Subject: can't find gcc-4 on cygwin
Download (untitled) / with headers
text/plain 385b
The latest version in CPAN doesn't appear able to find my compiler. It is looking for gcc-4.exe, but on my system gcc-4 is a symlink to gcc.exe fs01% dir /usr/bin/gcc-4 lrwxrwxrwx 1 ollisg None 7 Sep 13 10:42 /usr/bin/gcc-4 -> gcc.exe* thus, no gcc-4.exe fs01% perl -MDevel::CheckLib Couldn't find your C compiler Compilation failed in require. BEGIN failed--compilation aborted.

You need to update $Config{cc} ?

Actually cc is already set to gcc-4 (no suffix): fs01% perl -MConfig= -E 'say $Config{cc}' gcc-4

The attached diff fixes this issue for me. Appending $Config{_exe} is unnecessary on cygwin, since -x works with or without the extension if it is present, but only without it if testing a symlink. An alternate fix would be to check both with and without appending $Config{_exe}. observe: fs01% ls -l /bin/cpp* -rwxr-xr-x 1 ollisg None 694301 Dec 6 07:51 /bin/cpp.exe* fs01% perl -E 'say "yes" if -x "/usr/bin/cpp.exe"' yes fs01% perl -E 'say "yes" if -x "/usr/bin/cpp"' yes

this appears to have been fixed as of 1.02.

This bug is still affecting me even though I have the "my $compiler = File::Spec->catfile($path, $cc[0]) . ($^O eq 'cygwin' ? '' : $Config{_exe});" fix. I was able to get past it by deleting the symlink and instead making gcc-4 a hardlink to gcc.
