Shared library build of Chromium’s Content module
License: MIT License
As of Electron 4.0.0, libchromiumcontent is no longer built separately from Electron.
See Updated Electron build instructions.
If you're trying to build a pre-4.0.0 version of Electron, look at one of the old branches in this repo:
Is there a way to make cups optional? I don't have cups in my system and don't want it here any way.
Hi,
I was trying to build libchromiumcontent on my windows 7 32-bit Enterprise Edition. I have python 2.7 and Visual Studio 2013 Express installed.
When I tried update script, i got below error, please kindly help, thank you!
C:\xxx\libchromiumcontent>python script/update -t ia32

https://github.com/atom/libchromiumcontent/pull/69/files#diff-2544685f4860e4633fd5747ed88ec2caR6
As far as I am aware this flag tells chromium to build ffmpeg with support for things like H.264 and MP3 codecs. According to ffpmeg's own website the usage of this flag is a grey area at best and against patent laws at worst.
If a company decides to use electron to make a marketable product surely this flag being on by default leaves them open to potential legal issues due to codec licensing.
Can someone please confirm the legality around this flag in libchromiumcontent.
I am working on building a code integrity checker for Electron apps but I am lost at sea trying to understand the code.
It would be really helpful if you could tell me how atom/browser/api/browser-window.js connects to the cpp code? and Which are the exact processes which start when the electron app is launched?
And
where can I find detailed documentation of the code in atom/ and chromium_src/ ?

Building chromium 45 on a Mac with latest stable Xcode (7.0) is throwing so many errors, it's just impossible to monkey patch (here is one of them: https://chromium.googlesource.com/chromium/src/+/32dc9ad4eccdb86943b100a2741d8591f712ab0c).
Luckily, they've fixed all of these in 46!
Looking at atom-shell it seems (theoretically) to be able to run on Windows Vista (Extended support ends on 11 April 2017). There are two function exports, which Vista can't handle, namely RegisterTouchWindow and CloseTouchInputHandle, both in user32.dll.
These dependencies seem to stem from libchromiumcontent.
You can test it by looking at chromiumcontent.dll located at
atom-shell/vendor/brightray/vendor/download/libchromiumcontent/Release using the Dependency Walker.
I think it's just a matter of setting _WIN32_WINNT and WINVER to 0x0600 instead of 0x0602 in the corresponding .gypi file. Maybe brightray.gypi?
Chromium and Node.js are built to run on Vista. Is there anything that speaks against atom-shell being able to run on it, too? I'm fine with Atom to only support Win7+, but atom-shell is so versatile.
Thoughts?
Bootstrap is working after installing the dependencies mentioned in #52 , but script/build produces the following error

I was curious about why navigator.language == "" in atom-shell. After some researches I found this settings requires locales/[lang].pak files. I tried to copy the locales folder of a Chromium install into Atom-Shell and it worked as a charm.
I just created https://github.com/brightray. I'm planning to transfer this repo to that org today. Just a heads up!
Hi,
i'm trying to answer that question - in debian, it would be nice to be able to have the chromium package build spit out that shared library in the process, so that brightray could (dynamically) link to a libchromiumcontent debian package built out of chromium.
It would avoid maintenance of several versions of chromium.
Thanks for any info.
Jérémy.
With the later versions of Python 2.7.x, more strict SSL checking is performed. I'm getting this error when running script/update
URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed
Here is a workaround to disable SSL checking. This probably isn't a good long term fix though:
Is it possible to cross-compile and build libchromiumcontent and brightary for android without too much modification?
When building libchromiumcontent with Chrome 44 or 45 the following is not where the create-dist script thinks it should be

Here is the full error but there are more files than just this one. Basically devtools_discovery.lib and
http_server.lib are also not where the create-dist script thinks they are. Now I can move them myself to the locations it's complaining about and get the dist to succeed but that is janky.

We have an app written for node-webkit 0.9.2 and are very much wanting to switch over to Electron! However, we hacked node-webkit's chromium in order to support a drag-and-drop requirement: we needed certain images, when dragged out of node-webkit, to resolve an arbitrary file path at runtime. An example: you drag an <img> from node-webkit to your desktop, and it copies a network file to your drop target.
About our hack: we hook into the dragstart via client javascript, and the chromium hack will do the needful when it encounters our prefix:
e.dataTransfer.setData( 'text/plain', 'MAGIC-PREFIX:' + someData );My first question is: is there any way to do this without a chromium hack in Electron? I don't think so, but curious.
Second and more difficult question: It seems the chromium code has changed since our edits, specifically for Windows. We had previously modified content/browser/web_contents/web_contents_drag_win.cc which no longer exists. In fact, within content/browser/web_contents/ I am not seeing any _win-suffixed files.
The closest file that contains some relevant code matching our edited code is within web_contents_view_aura.cc. Does this seem relevant?
I really appreciate any information you have. Modifying Chromium isn't my daily fare, and I really appreciate any expert advice on this.

The only issue in the previous step was that it complained about xscrnsaver, which does not appear in apt-cache search xscrnsaver on the platform. The complaint is this:
No package 'xscrnsaver' found
gyp: Call to 'pkg-config --cflags xscrnsaver' returned exit status 1 while in build/linux/system.gyp.
Otherwise it appears to complete successfully. I would not expect this to cause the build script to fail at the step above.

My system has Python 2.6 which I believe is likely the source of the error, (as from what I can tell subprocess.check_output() was introduced in 2.7), but if I re-run the command (without a git clean) it doesn't appear to have an error (rather than running up against the same error).
Maybe this error is non-fatal, maybe it isn't, but the scripts seem like they should make that clearer.

Is it possible to remove the gconf dependency when building libchromiumcontent?
I am trying to make custom build but I have to changes to some chromium src files. I see the patches folder at figures its done by patches. I cannot figure out the right way to make patches though.
Hi,
I'm trying to build libchromiumcontent in a docker centos7, I had a sad work try-fail build to detect/install all dependencies.
I think it can be so ease for others users if you add this instruction to read me file:
yum install -y pciutils-devel git tar gcc pkg-config atk-devel pulseaudio-libs-devel gdk-devel gdk-pixbuf2-devel gdk-pixbuf2 pygtk2-devel libXtst-devel libXScrnSaver-devel dbus-devel GConf2-devel libgnome-keyring-devel libexif-devel gperf
After it I was able to build.
electron has upgraded to Chrome v45 since version 0.32.0, but the corresponding tag/release cannot be found in libchromiumcontent.
create-dist used to create a zip file that contained debug symbols. This made it possible to step through Chromium code in a debugger when using a prebuilt version of libchromiumcontent. It looks like the symbols zip got removed in #98. It'd be great to bring it back.
building on master 7a34617, it fails :
../../content/common/gpu/media/vt_video_decode_accelerator.cc:321:42: error: use of undeclared identifier 'GL_TEXTURE_RECTANGLE_ARB'
This is my first attempt dabbling with libchromium.
I did : script/bootstrap; script/build
Not yet attempted to compile from a release.
Would it be possible for atom-shell to bypass existing protections in chromium preventing hardware video decode on intel chipset with linux? The idea would be to implement this chromium ticket Issue 176883018: Remove additional protection of kDisableAcceleratedVideoDecode in bpf_gpu_policy_linux.cc. that has been closed for the sake of stability.
That would be a great addition for linux app builders out there.

Is there something I'm missing with yasm, or a way to generate the missing config.asm files ?
I've noticed that pdf.lib is missing after building and it won't be available to be packaged into dist via create-dist. As an interim fix I've just included it from the official build of libchromiumcontent.
electron v0.36.3 introduced the support for the Widevine CDM plugin, which makes Netflix works inside Electron.
However, Chrome 47 (the initial release) shipped with a major bug that makes Netflix videos have a broken ratio (see screenshot).
Chromium pushed a fix pretty quickly but it's not in libchromiumcontent.
Here is the chromium patch and the extremely small diff.
Would it be possible to backport that fix into libchromiumcontent and include it in the next electron release? (on my side, the sooner the better).
Also, tell me and I would happily create a PR for this.
Thanks!
i would prefer pre-build libchromiumcontent with all of these together(#113), and i was just wondering is it safe and legal to use tools like dumpbin to generate link lib from chromiumcontent.dll in atom editor release.
in this way, we only need to get the header files, then use libchromiumcontent in our own programs.
thanks!
Hello, I'm very interested in this project, I tried to build this library couple of times with no luck.
My last try on a Mac stopped as my hard disk space ran out (didn't realize how big it is).
Even if the build succeeded, I would need document to understand how to use the library.
So I was wondering if there's plan to publish pre-build library, which includes library, linking library, header files, documentation?
Thanks!
Hi
I need to port my CEF based application and use libchromiumcontent instead of CEF.
I tried to build libchromiumcontent in windows. Everything worked fine with no error but size of chromiumcontent.dll is very small !
(79 KB in out\Release_x64 and 21 KB in out_component\Release_x64)
Also , there is a content.dll (32 MB) alongside with the rest of chromium dlls in out_component\Release_x64 but not in out\Release_x64
I tried several times with both 41.0.2272.76 and 42.0.2311.107 (Debug and Release , 32 and 64) , master and atom branch of libchromiumcontent..
How can I build an standalone chromiumcontent.dll same as the one that is distributed with Atom editor?
merge
chromiumcontent.dll
msvcp120.dll msvcr120.dll vccorlib120.dll
xinput1_3.dll
into chromiumcontent.dll
merge ffmpegsumo.dll msvcp120.dll msvcr120.dll
into ffmpegsumo.dll
merge content_resources_200_percent.pak
content_shell.pak
ui_resources_200_percent.pak
natives_blob.bin
snapshot_blob.bin
into chromiumcontent.pack
Would it be possible to include the license information of third party libraries used by chromium in this repo? There seems to be a python command [1] to generate the license information.
The rationale is that for VS Code when we consume Electron we need to include the full license information of Chromium and its third party libraries. Currently this is a very manual process for us and ideally this is just provided through libchromiumcontent.
[1] https://src.chromium.org/svn/trunk/src/tools/licenses.py
The following occurs on my maschine when I try to prepare the build
Error: Command svn checkout https://cld2.googlecode.com/svn/trunk@84 /Users/Ingwie/Work/brightray/vendor/libchromiumcontent/vendor/chromium/src/third_party/cld_2/src --revision 84 --non-interactive --force --ignore-externals returned non-zero exit status 1 in /Users/Ingwie/Work/brightray/vendor/libchromiumcontent/vendor/chromium

Any help on here?
Chrome 30 went stable yesterday. We should update!
I have successfuly built the library; but where to upload it now? o.o;
Would using my own server work too?
The current build process of electron builds a custom version of chromium through the module libchromiumcontent. This is all very well but there is a single flag inside this build process found here that turns your build of chromium into GPL licensed code.
That flag builds ffmpeg with a whole load of additional codecs which are licensed under GPL. An example of such a codec is H.264. It has been confirmed that libchromiumcontent builds this codec in this issue and confirmed that it is GPL licensed on ffmpeg's site. This codec is just one example of a GPL component included in the ffpmeg build libchromiumcontent generates.
Electron is currently licensed under the MIT License which is against the terms of GPL. In lamens terms, anything that uses GPL licensed software must also be GPL licensed. This is a MASSIVE issue for many companies that use electron to ship commercial grade applications. It means that any application they ship can be claimed to have to be GPL and they MUST release their source code.
Further evidence of the GPL nature of this build style is found in the nw.js documentation here.
We would like to request that you ship non-GPL versions of the prebuilt electron packages and update your licenses / README to reflect the fact that some packages use GPL licensed software.
We have attached a PR here (#179) to help fix this issue. This PR basically moves the change in this commit to an environment variable so you can easily turn on / off the GPL version.
Attempting to build on a CentOS system and I had to run the following to get bootstrap to run.
sudo yum install pciutils-devel cups-devel libudev-devel
Didn't see these in the README.md, so might be nice to mention.
ehh...
I tried to build libchromiumcontent but it failed to build with following errors.
anybody can help?

I have an app using atom-shell that offers video chat using OpenTok, which in turn uses WebRTC.
When I use the video chat function, I see a warning appear on the command-line:
WARNING: no real random source present!
AFAICT, this warning is coming from the libsrtp dependency built into Chromium. There is a file in libsrtp (https://chromium.googlesource.com/chromium/deps/libsrtp/+/master/srtp/crypto/rng/rand_source.c) that is supposed to be compiled with either -DDEV_URANDOM (Unix) or -DHAVE_RAND_S (Windows). If compiled with neither, it prints the warning and generates random numbers using plain, insecure rand().
I ran strings on atom-shell's libchromiumcontent.so, and I saw the same "no real random source present" message, so I suspect that brightray is compiling the libsrtp file incorrectly, and (presumably) it's weakening WebRTC security.
I have this patch file but I don't know how to make a pull request on this project.

Is there a way to make it cups independent?
I'm using Gentoo Linux x86_64, that currently don't have a package for libchromiumcontent. I install atom editor with the prebuild libchromiumcontent (yes, Linux build) but that depends on cups (yes, Common Unix Printing System) and forces me to install the net-print/cups, but I really no use this.
All other packages on my system uses the cups library as an optional dependency, but libchromiumcontent don't work without cups.
There is no way to make it optional, as the other programs?
Currently building libchromiumcontent requires checking out all Chromium's codebase, which is huge and slow. We should download Chromium's source tarball and build from it instead, I've built a project to generate source tarball automatically: https://github.com/zcbenz/chromium-source-tarball.
compiling libchromiumcontent from source is listed as a way to compile other projects on Debian Wheezy that use it. The issue is Debian 7 stable uses libc6 2.13, when projects like Atom.io package libchromiumcontent .so as a build dependency (:confounded:) which is compiled against libc6 2.14. So I clone this repo, and it now ALSO requires libc6 2.14:
../../third_party/llvm-build/Release+Asserts/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by ../../third_party/llvm-build/Release+Asserts/bin/clang)
../../third_party/llvm-build/Release+Asserts/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.15' not found (required by ../../third_party/llvm-build/Release+Asserts/bin/clang)
../../third_party/llvm-build/Release+Asserts/bin/clang: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /home/nmartinssd/Projects/libchromiumcontent/vendor/chromium/src/third_party/llvm-build/Release+Asserts/bin/../lib/libstdc++.so.6)
ninja: build stopped: subcommand failed.
Is this intentional? it seems clang which is packaged with libchromiumcontent now also requires libc6 2.14 or higher
