Bug #28547 for Perl-Dist-Strawberry: Incorrect value of Config{'lib

Sun Jul 29 21:57:48 2007 MIKEM [...] cpan.org - Ticket created

Subject:

Incorrect value of Config{'lib_ext'}

In strawberry-perl-5.8.8-alpha-2.exe the value of $Config{'lib_ext'} is '.a'. For building external modules on Win32, it should be '.lib', else MakeMaker and Module::Build are unable to find the .lib files when linking some CPAN modules like Net-SSLeay. Tested on XP and Server2003

Strawberry Perl is build with MinGW -- a windows port of GCC -- and thus uses ".a". In this respect, Strawberry just follows the default setting determined by perl5-porters. See win32\config.gc and compare it to win32\config.vc. However, MinGW is supposed to recognize .lib as well in many cases. See http://www.mingw.org/MinGWiki/index.php/FAQ for how libraries must be specified to be linked. Was the correct directory added to $ENV{LIB}? Also, some distribution assume that they will be compiled with MVC and may not adjust their library specifications appropriately for other configurations.

Yes, this was my mistake: when openssl is compiled with the mingw that comes with strawberry perl, it does indeed produce .a files, which are found correctly when Net-SSLeay is built.. I guess its really a problem with MakeMaker and or Module::Build in that if lib_ext is set to '.a', 'perl Makefile.pl' just wont find library files that end in .lib. Not a problem if everything is compiled with mingw, but if you are mixing and matching with .lib+.dll from some other package then it may not work. I dont think this is a strawberry perl problem. Anyway, thanks for your prompt response. Cheers. Show quoted text

Not a Strawberry problem
