perl -V:cc still says "gcc-4"

perl -V:cc still says "gcc-4"

[Warren Young]

Many moons ago Cygwin "gcc" became GCC 4.  Later, Cygwin dropped the 
"gcc-4" wrapper package.

Unfortunately, this means Perl modules that only come in native (XS) 
form don't compile because perl -V:cc says "gcc-4".  I tried creating a 
symlink from gcc-4 -> gcc in /bin, but it didn't help.

STC: cpanm Text::Xslate

Yes, I've posted about this some time ago.  You absolutely need to name
the symlink "gcc-4.exe".  You could also patch out the EXEEXT appendage
that makes that particular check fail when it encounters a symlink of
just "gcc-4", but renaming the symlink is easier.

This only affects 32-bit Cygwin, by the way.  I tried the STC on 64-bit 
Cygwin where perl -V:cc says "gcc", and it built and installed the 
module, and the module works.

This is how I build perl-Text-CSV_XS - I create a symbolic link as you 
described. Using cygport I was able to produce a Xslate DLL, but I 
couldn't run the test suite as I'm missing many dependencies.

Does the attached help?

Dave.

This is not my experience. My link is called 'gcc-4' pointing to 'gcc'; 
there is no '.exe' extension in either source or destination. This gets 
XS modules compiling for me.

Dave.

That may have done it.  I'd have to do some manual CPAN package 
uninstalls and reinstalls, testing under various conditions to be sure, 
and can't be bothered.

I can say that I *also* required a g++-4 -> g++ symlink.  I made it with 
.exe, just to be safe.

Thank you, but I wasn't actually trying to make a Cygwin package.  I 
just noticed this while composing my answer to Andrew DeFaria in his 
mod_perl thread.  I tried to build Dancer::Template::Xslate (which 
depends on Text::Xslate) and it failed, so I thought I'd report it, 
hoping it would give the Perl maintainer incentive to update the package.

...which turns out to not be necessary, since Reini Urban's 5.18.2 
32-bit test build doesn't say "gcc-4" any more.  Assuming no regression, 
this will be fixed when Cygwin moves formally to Perl 5.18.

So never mind. :)

Indeed - I have already built perl-Text-CSV_XS for perl-5.18.2, and no 
'gcc-4' symlink was necessary.

Glad you managed to get Text::Xslate built in the end,

Dave.
