Cannot compile on OS X about webp HOT 35 CLOSED

Issue 4 has been merged into this issue.

Issue 5 has been merged into this issue.

I tried following steps and able to build webpconv:

1.) Installed 'Mac Dev Tool (XCode)'  for getting dev-dependencies like gcc, 
gnumake (make) etc.

2.) Installed libpng & libjpeg disk image files (dmg packages from 
'http://ethan.tira-thompson.org/Mac_OS_X_Ports.html' ).

3.) Installed 'yasm' tar ball (Source.tar.gz) from 
'http://www.tortall.net/projects/yasm/wiki/Download' and followed instructions 
at 'http://www.tortall.net/projects/yasm/ticket/110'.

4.) Installed libvpx (libvpx-v0.9.5.tar.gz) from 
'http://code.google.com/p/webm/downloads/list' (./configure && make && sudo 
make install).

5.) Installed 'leptonlib-1.066' & 'libwebp' from local 
'webp-leptonica-0.0.3.tar.gz' tar ball (should be OK with previous version 
'webp-leptonica-0.0.2.tar.gz' too).
      - (./configure && make && sudo make install) for leptonica & 
      - (./configure && make) for libwebp to build libwebp/src/webpconv binary.

Where is the 0.0.3 tarball? I've got all the libraries already just a slightly 
older version of libvpx which I can update if necessary.

MacPorts can be obtained from http://distfiles.macports.org/MacPorts/

We are verifying 0.0.3 tar-ball, but following these steps over 0.0.2 tar ball 
should also work. We will be releasing 0.0.3 tar-ball in another day or two.

One another observation regarding building 'webpconv' binary and it's dependent 
lib 'leptonica'. I ran commands in this sequence:
cd webp/leptonlib-1.066/
./configure && make && sudo make install;
// After this step, 
cd ../libwebp/
./configure && make

After installing leptonlib-1.066, verify that you have 
'/usr/local/lib/liblept.a' and '/usr/local/include/liblept/*.h'

Note that 0.0.3 has been made available in the downloads section.
please follow these instructions (that I'll be pushing to our website next 
Monday)

1) Download MacPort for your Mac-OS version.
2.) Install MacPorts to the default target directory ‘/opt/local’.
3.) Update macports
    sudo port selfupdate
4.) Install the necessary dependencies 
    sudo port install libvpx libpng jpeg giflib
5) Download latest ‘webp-leptonica’ source tar ball and build 
'leptonlib-1.066' & 'libwebp'  on your computer
    cd webp/leptonlib-1.066/; ./configure && make && sudo make install;
    cd ../libwebp/; ./configure && make && sudo make install;
This will install ‘webpconv’ binary at path ‘/usr/local/bin/’

Hi Charlie -
Were you able to give this a try.

Tried verifying build+installation on Mac-OS version 10.5 & 10.6 and above set 
of instructions are working for us.

Hi Vikaas,

for some reason I wasn't notified of updates to the ticket. Nice to see you've 
been working on this. Unfortunately it's still not working for me.

I get errors building leptonica:

Although I don't think this should matter as there a port of leptonica @ 1.66

But building lipwebp still fails:

This is with the 0.04 source files. If we get this fixed we can add a port for 
webp to MacPorts which should simplify things for others interested.

FWIW the same error occurs when trying to build webp on FreeBSD 8 from the 
port: http://www.freebsdports.info/ports/graphics/webp.html

The [email protected] needs patch for webpconv and the patched version is shipped 
in the source tar ball (ver 0.0.4)

When you untar the 0.0.4 source files, do following steps:

1.) cd webp/leptonlib-1.066;

2.) sudo mkdir /usr/local/lib; // This is required as 'sudo make install' in 
next step will install liblept.a there

3.) ./configure && make clean && make && sudo make install;

4.) ls -al /usr/local/include/liblept/leptprotos.h; // Verify the date-time 
stamp of this header include file.

5.) ls -alt /usr/local/lib/liblept.a;  // Verify the date-time stamp of newly 
created liblept.a

6.) grep pixWriteWebPwithTargetPSNR /usr/local/include/liblept/leptprotos.h; // 
Verify that this patched leptonica source code (header) have the necessary 
functions required for webpconv.

7.) strings /usr/local/lib/liblept.a | grep pixWriteWebPwithTargetPSNR; // 
Verify that this patched version of liblept.a have the necessary functions 
required for webpconv

8.) cd ../libwebp;

9.)  ./configure && make clean && make && sudo make install;

10.) libwebp build command should look like:
g++ -Werror -DPACKAGE_NAME=\"libwebp\" -DPACKAGE_TARNAME=\"libwebp\"

11.) webpconv binary link command should look like:
g++ -Werror -Wall -O2 -g -O2 -L/usr/X11R6/lib -L/usr/local/lib -L/opt/local/lib 
-L/opt/local/lib/liblept -lgif -o webpconv webpimg.o webpconv.o -llept -ljpeg 
-lpng -lz -lm -lvpx -lpthread -lvpx

BTW, ranlib errors while building liblept.a can be ignored.
The liblept.a will not get installed to /usr/local/lib in case you haven't done 
'sudo mkdir /usr/local/lib'
In that case, the default binding might be going with 
'/opt/local/lib/liblept/liblept.a', that's coming from unpatched version 1.066 
and hence doesn't have functions required for webpconv.

Alternatively you can also try to upgrade your standard leptonca to next 
version 'http://www.leptonica.com/source/leptonlib-1.67.tar.gz'

Hi Vikaas,

first off can we read reopen this ticket as it is not fully resolved. Thanks 
for updating the build instructions. I've submitted a patch to the MacPorts 
version of leptonica, http://trac.macports.org/attachment/ticket/27511/, so 
that the build should get easier:

sudo port install leptonica && cd libwebp && ./configure && make clean && make 
install

Or, hopefully soon just sudo port install webp

However, there are still problems. The leptonica port installs the headers to 
/opt/local/leptonica so the makefile needs updating for this. Unfortunately I'm 
still getting an error. liblepta does exist in /opt/local/lib

Port submitted to MacPorts

The log says that it could not find path '/opt/local/lib/liblept'
Can you also try creating that path.

I have opened this issue.

Thanks for reopening the ticket.

I can't see why that should make a difference if I add that folder. After all 
it only expects /opt/local/lib/liblept.a. Of course, it represses the error. 
Compilation does work and it does install. So we probably now just need to work 
on fixing the paths.

Testing the binary I get

pixWriteWebPwithTargetPSNR Failed. See previous error messages. Turn on debug 
build if you aren't seeing enough detailed error messages

Thanks for your patience. Let me see if i can reproduce this issue.
Any chance you might be using standard leptonica (ver 1.66 or 1.67) instead of 
the patched leptonica.

Can you also evaluate other issue you raise (issue 35) for FreeBSD 8

I'm using the leptonica 1.67 with the diff to the portfile attached to 
/opt/local/var/macports/sources/rsync.macports.org/release/ports/graphics/lepton
ica/Portfile

After that sudo port install leptonica
cd libwebp etc.

I've filed an issue for the FreeBSD port as I'm less experience with FreeBSD 
ports. Currently I think the port doesn't depend on the leptonlib port which is 
why this is still @ 1.60

By default webp format is not supported in leptonica and hence we need to ship 
patched ver (currently 1.66) with the webp source tarball.
I can understand the pain. Can you give a try building liblept.a from the 
'webp-leptonica' source tarball that have the patched ver inside 'webp' 
directory.
We are working on removing the requirement to ship patched leptonica within 
webp tar-bundle. 

aagh! Sorry, I think the combined archive is a *bad* idea. Isn't it possible to 
get the webp patch into leptonica? If not best to have something like a "port" 
that patches the leptonica source rather than distributing it. I think this 
makes handling other downstream packages easier as well.

Creating the POSIX paths does let webp build and install. But I get a 
segmentation fault when I try it.

Can you upload the image you are trying to convert (PNG to webp ?)
Can you try the same conversion on other port (BSD) as well. Also try some 
other image as well on Mac-OS as well.

I can confirm the segfault occurs with other images on Mac OS. No problems on 
FreeBSD. Sample file included.

Meanwhile someone has created a usable port for Mac OS (it will build and 
install at least) based on Leptonica 1.67. Depending on what you plan to do 
with the patches to leptonlib this will be the way to go: either support for 
webp goes into leptonica or a new port for leptonlib-webp is created which 
patches the leptonica sources and warns of the incompatibility to straight 
leptonica. See https://trac.macports.org/ticket/27518 for details.

How to use the port: 
# download the port and unpack it to a temporary folder
tar -xjf webp.tar.bz2
# assuming the unzipped port is in the current folder
sudo port install ./webp

This will build leptonica-1.67, if not already installed, and webpconv against 
it.
NB. any attempt to use webpconv built like this will fail because of the 
missing patches to leptonica.

Can you try installing the next version 0.0.5.
Follow the steps mentioned in 
'http://code.google.com/p/webp/issues/detail?id=3#c13' and check if the 
'SIGSEGV' is coming on Mac-OS port.

webp compile error:

Undefined symbols:
  "_pixReadWebP", referenced from:
      _main in webpconv.o

Can you supply a diff for the leptonica files so that we can work we that?

In case webpconv is not getting symbol 'pixReadWebP', it's linking to old 
leptonica-patch code.

I have uploaded the patch file between two source tar-balls (0.0.4 & 0.0.5).
Ensure after installing 'leptonlib-1.066' (from 0.0.5 version), that you have 
function 'pixReadWebP' defined in 'leptonlib-1.066/src/webpio.c'

You're right it was still using leptonica-1.67
I cleaned that out and was able to compile and install. Segfault still happening

Vikaas, could you post the patch to leptonlib that adds support for webp?

The leptonica-patch code is already distributed along with webp code in 
webp-leptonica tar ball. The patch file I created was from 'diff' result of the 
two source tars only (0.0.4 & 0.0.5).

For the SegFault issue, can you try on some more images (webpconv -format PNG 
*.png) and create a new issue for the same. I believe this bug/issue is already 
loaded with Mac-OS compile/Installation comments.

Also (if possible), can you try installing 0.0.5 source tar on some prestine 
Mac-Pro (in case you have access to another Mac-OS). I myself was not able to 
reproduce this issue (on Mac-OS ver 10.6). Will try on some other version of 
Mac-OS (prestine Mac Pro with versions 10.5 & 10.6) myself as well.

The segfault has been confirmed on another machine. It seems to be related to 
x86_64 as it is not raised when built for i386. However, the files created by 
the i386 build do not seem correct are not visible to the weppy plugin.

Hi, with the 0.1 release the port builds fine so this ticket can be closed. The 
install can be updated to simply `sudo port install webp`

Still getting segmentation faults when actually using this. No further 
information available.

Sorry, ignore comment#33 that was caused by a previous build. 0.1 runs fine on 
MacOS!

Great. closing this issue. feel free to reopen if need be
sudo port install webp 
works great
