Topic: Unable to cross compile on a Windows machine

I am running a cross-compiler in a Git Bash window and get an error with wolfSSL version 5.5.4 during CMake. The problem is with the execute_process command in CMakeLists.txt, which indicates that "user_settings_asm.sh is not a valid Win32 application". This makes sense because of how execute_process works. This looks like newer functionality because this was not a problem with wolfSSL version 5.4.0.

Does anyone have any guidance on how to address this issue?

Also, I had to do some tricks to see the actual error message because the doesn't display the result of the call to execute_process. It would be nice if it provided the results when an error occurs.

Re: Unable to cross compile on a Windows machine

I can confirm I have this issue as well building on Windows with CMake. `user_settings_asm.sh` is being run on a Windows machine which obviously wouldn't work.

Hello jferraris,

This issue was fixed in wolfssl's `master` branch.  Please see the following pull request that has already been merged: https://github.com/wolfSSL/wolfssl/pull/6085

Warm regards, Anthony

Re: Unable to cross compile on a Windows machine

Hi Anthony,

I believe this fix only works if you have a Unix based shell set in the environment variable. Building with CMake on Visual Studio on Windows still has the same issue.
I attempted to change my $SHELL environment variable but this didn't actually do much for me.

Appreciate your response!
Jordan

Re: Unable to cross compile on a Windows machine

The issue has returned for me in version 5.6.4 because the unix version of the command does not include the prior fix.
