What did you do before the bug happened? (Steps to reproduce your issue)
Cross compile git from source (git-2.48.1) using the meson build system
(Buildroot package experimental converted from autoconf to meson).
What did you expect to happen? (Expected behavior)
Execute command 'git fetch' on the target without failure.
What happened instead? (Actual behavior)
Command 'git fetch' on the target failed.
What's different between what you expected and what actually happened?
Debug with strace showed the following difference:
- o.k (autoconf):
679 execve("/bin/sh", ["/bin/sh", "-c", "git-upload-pack '/home/git-repo"..., "git-upload-pack '/home/git-repo"...], 0x55c342ce4420 /* 17 vars */ <unfinished ...>
- failure (meson build):
6861 execve("/usr/bin/sh", ["/usr/bin/sh", "-c", "git-upload-pack '/home/git-repo"..., "git-upload-pack '/home/git-repo"...], 0x5639ab382210 /* 17 vars */) = -1 ENOENT (No such file or directory)
The meson build tries to execute the non-existent '/usr/bin/sh' (instead of
'/bin/sh' as the autoconf build), 'which sh' on the host returns
'/usr/bin/sh'...
From meson.build
[...]
186 shell = find_program('sh', dirs: program_path)
[...]
685 '-DSHELL_PATH="' + fs.as_posix(shell.full_path()) + '"',
Do not use the result of 'find_program('sh',...)' for '-DSHELL_PATH='
(at least not for cross-compile), use fix '/bin/sh' instead or make it
configurable via a meson option?
Regards,
Peter
