Hi

On a new installation i get this error when trying to use apt-cyg:

> apt-cyg update
/usr/local/bin/apt-cyg: line 424: C:/Windows/system32/cmd.exe: Bad address

I am new to this so i can't tell if this problem is specific to cygwin-protable or apt-cyg. But it seems to me that apt-cyg can't find the cache and mirror directories and that causes the setup.ini creation to fail.

Any idea?

the default python is python3.7, but I need 2.7 instead, how do I install python2.7 and replace 3.7 ?

Hi,
When selecting INSTALL_ANSIBLE=yes and ANSIBLE_GIT_BRANCH=stable-2.14, I systematically get the same error at ansible startup stating that function wcwidth cannot be found.
This comes from this line https://github.com/ansible/ansible/blob/stable-2.14/lib/ansible/utils/display.py#L47 which is failing to find 'c' library.
The test can be easily done like this
python -c 'import ctypes.util; print(ctypes.cdll.LoadLibrary(ctypes.util.find_library("c")))'
returning currently
<CDLL 'None', handle 100400000 at 0x6fffffec7210>

I thought it was a Cygwin issue but a "classic" install of cygwin does not have the issue and returns the cygwin libc implementation like expected
<CDLL 'cygwin1.dll', handle 180040000 at 0x6ffffffa4ca0>

I looked at differences in the environment, did a bunch of tests and could not find the right variable to set or package to install.
I guess there is some dependency missing in the config file.

NB: the wcwidth usage has been introduced in ansible 2.11, picking this version solved the issue but I am still looking at how to make 2.14 work.

Any idea how I could solve this ?

After:

• installing cygwin (successfully) with cygwin-portable-installer.cmd in win11
• click on cygwin-portable.cmd

I get the error reported in the title.
Installing bash-funk manually all ok.

Observation:

Upon installing via the .cmd file, and running the generated entry point cygwin-portable, the following error is found (paraphrased):

Can't create process. 
This version of %1 is not compatible with the version of Windows being run. Check that the program is compatible with this architecture, 32 or 64 bits, and contact your software distributor.

The cygwin-portable installer .cmd file seems to check the wrong environment variables for architecture, looking to an envvar called "PROCESSOR_ARCHITEW6432" when it should be looking for "PROCESSOR_ARCHITECTURE".

Even if manually correcting the W6432 variable sections so that PROCESSOR_ARCHITECTURE is read instead, the cygwin-portable installer insists on downloading ConEmu 64bit.

Expected Behaviour

The components of software downloaded and installed are compatible with the OS and the software can be run.

Observed Behaviour

The components of software downloaded and installed are not compatible with the OS and the software can't. be run. Furthermore, the installer wrongly reports a successful installation.

System: Windows 7 SP1 32-bit virtual machine on a Linux Debian 10 64-bit host.

Guest system's envvars:

PROCESSOR_ARCHITECTURE=x86
PROCESSOR_IDENTIFIER=x86 Family 6 Model 58 Stepping 9, GenuineIntel
PROCESSOR_LEVEL=6
PROCESSOR_REVISION=3a09

No variable called PROCESSOR_ARCHITEW6432 is found, yet the installer takes the wrong paths (at eg.: lines 148, 429) and installs ConEmu 64 bit to run on a 32-bit OS. Also, while I have not definitively verified it, it seems to install the wrong architecture of cygstdc++-6.dll.

Recommended Fix Pathways

• Provide a better mechanism than reading envvars for detecting the architecture that is actually running (not the architecture that the hardware is "capable of").
• Provide an installer flag to perform an alternate architecture install.

I installed it but when I run it on a different computer it show account of the users of the computer instead of my user. Please help me??

When running the script with its defaults, an error message is shown on the screen and continues. I don't know exactly the consequences of the problem:

...

What can I do?

Hello,

Thank's for your greatfull project ! Just a simple question: if i want to personalize this installer (to adapt to my own application requirements) remove all no necessary and add required things in https://github.com/vegardit/cygwin-portable-installer/blob/master/cygwin-portable-installer.cmd is there the correct way ? Or there are variables to personalize ?

So it looks like you can select normally but when you run vi (alias to vim in /etc/profile.d/vim.sh ? ) it makes it so you have to use shift+click to select. Not an issue if this is the desired result but for consistency not sure how to fix it.

Reference:
Maximus5/ConEmu#399 ( shift + click ) starts copy in conemu

also note vi and vim are different :

$ diff /usr/bin/vi /usr/bin/vim
Binary files /usr/bin/vi and /usr/bin/vim differ

Please be aware that users may be unable to download the cygwin installer via the vbscript method if their system doesn't support TLS 1.1/1.2 in WinHTTP connections.

They'll see an error when running the installer: "An error occurred in the secure channel support".

The solution is to make the registry changes or apply the hotfix detailed here.

Please add this to the README or perhaps consider a workaround - such as allowing users to manually download and place thee cygwin installer executable in the required subfolder - if possible.

I had done a standard installation without any change to installer file. the installer later reported a successful installation including node.js
When type npm command, i get below error message:

$ npm -v

the installer bat file is placed in C:\PortableApps\CygwinPortable\ but above command is executed in cygwin env.
any idea how to fix it? thanks.

I have configured cygwin-portable-installer.cmd for my needs, but when I run it, it aborts with this error message:

This looks like something we have been needing.. Is there a way to also add AWS CLI to this?

apt-cyg is dead and the authour reccomends the installer called sage.
https://github.com/svnpenn/sage
i'm not sure how the change would work but the cygwin folder would need to be writable and not read ol since windows sets folders to be this and sage doesn't like it.

Or you could alter the script to download and use setup.exe

Don't have this issue with my old Cygwin env same binary for find too. Can't seem to find a fix with the conemu :( :

If I just run bash.exe from CMD it works fine:

bash -c "/bin/find . -exec /bin/ls '{}' \;

Cannot delete cygwin folder after installation.

Tried to take ownership however still comes out with this error
rmdir : Directory A:\apps\cygwin-portable\cygwin\ cannot be removed because it is not empty.

Hello Vegardit,

First of all I would like to thank you for such a great tool, always wanted to have portable cygwin+comemu stack.

I wanted to ask if you experienced any similar issues while installing Cygwin portable.
I recently tried to install it on my PC (Windows 10 x64) and found that Cygwin does not create its core files during setup process. It hangs on "Replacing etc/fstab" stage and goes to :fail afterwards.
After this I looked into %CYGWIN_ROOT% folder and found that there are no core files (/home, /bin, etc.)
Only:
./etc/setup/setup.rc
./etc/setup/timestamp
./setup-x86_64.exe

Tried different mirrors, creating fstab file manually, running installation process from virtualbox VM with no success. The weird thing is that one week ago cygwin+conemu was installed without issues on my friend's PC (also Windows 10 x64)

Any help would be highly appreciated.

Regards,
Alex

Per these issues cmder and ConEmu

The latest version of cygwin cannot work with ConEmu/cmder. Can the ability to choose a version of cygwin to install be added to this script.

I was not sure so i thought i'd ask first about these two lines.

https://github.com/vegardit/cygwin-portable-installer/blob/master/cygwin-portable-installer.cmd#L284-L285

If i am reading this right you want to set a custom path for the packages cache. Then use sed to edit the default line. The problem i see is that it matches nothing as the format of the line is :

last-cache
	C:\...\...\...\.pkg-cache
mirrors-lst

This works for me actually edit the line as it is created by the Cygwin installer.

pkg_cache_dir=$(cygpath -w "$CYGWIN_ROOT/../cygwin-pkg-cache")
sed -ri 's#(.*)\.pkg-cache$#'"\t${pkg_cache_dir//\\/\\\\}"'#' /etc/setup/setup.rc

Edit: what it makes me think though is if this is even necessary to do as I dont really see the purpose it serves.

the .cmd fails as soon as it tries to create the download script if there's a space in the main folders name, or any folder above it. IE: C:\Users\Firstname Lastname\Downloads\cygwin portable

I think the problem is the double quote in the path.

I'm using Windows 10 latest version.

For context: I main Linux systems and only run Windows via a number of VMs - development, work, etc. In order to save space and synchronize featuresets, my intention was to install a single instance of cygwin‑portable on a shared folder in the real host and then run the instance by mapping the networked drive on the Windows VMs.

The configuration for the shared folder is as follows:

[winshared]
browseable = yes
force user = winshared
force group = sharing
force create mode = 0777
force directory mode = 0775
acl allow execute always = True

Cygwin-Portable itself installs correctly. The problem is that the post-setup scripts in charge of installing apt-cyg, which I think run upon first opening conemu? download and install apt-cyg with some sort of permission issue that makes it unavailable:

root@Usuario-PC ~
$ ls /usr/local/bin
drwxrwxr-x  1 Unknown+User Unix_Group+1885   0 abr 13 12:44 .
drwxrwxr-x  1 Unknown+User Unix_Group+1885   0 abr 13 12:34 ..
-rw-rw-r--+ 1 Unknown+User Unix_Group+1885 65K abr 13 12:48 apt-cyg

root@Usuario-PC ~
$ apt-cyg
bash: /usr/local/bin/apt-cyg: Permission denied

Attempting to chmod +x the file has no observable effect:

root@Usuario-PC ~
$ chmod ugo+x /usr/local/bin/apt-cyg

root@Usuario-PC ~
$ ls -lha /usr/local/bin/
total 1,0M
drwxrwxr-x  1 Unknown+User Unix_Group+1885   0 abr 13 13:04 .
drwxrwxr-x  1 Unknown+User Unix_Group+1885   0 abr 13 12:34 ..
-rw-rw-r--+ 1 Unknown+User Unix_Group+1885 65K abr 13 12:48 apt-cyg

getfacl reports available permissions:

root@Usuario-PC /usr/local/bin
$ getfacl apt-cyg
# file: apt-cyg
# owner: Unknown+User
# group: Unix_Group+1885
user::rw-
user:Unknown+User:rw-
group::r--
group:Unix_Group+1885:r--
mask::rw-
other::r--

But using setfacl to try and modify them also has no observable effect.

The only apparent way to make the apt-cyg binary available is to raw-copying to a new filename, but it can't be placed anywhere in $PATH:

root@Usuario-PC /usr/local/bin
$ cat < apt-cyg > /usr/bin/apt-cyg2
$ cat < apt-cyg > /usr/local/bin/apt-cyg2
$ cat < apt-cyg > /tmp/apt-cyg2

$ /usr/bin/apt-cyg2
bash: /usr/bin/apt-cyg2: Permission denied
$ /usr/local/bin/apt-cyg2
bash: /usr/local/bin/apt-cyg2: Permission denied
$ /tmp/apt-cyg2
[normal apt-cyg output]

I presume this error could affect other components of Cygwin-Portable too, but since apt-cyg is not working correctly I can't install more software to test ATM. The components first installed by the system (ie.: anything listed in installer.cmd the first time) work without issue, but I can't tell at the moment about anything installed after.

For the record, installing Cygwin-Portable on the actual hard-drive works as intended, but copying the result to the shared folder results in the same errors as the above. Which defeats the point of having the install being portable.

When running cygwin-portable.cmd I get strange output, example:
