Just unpack, 'perl Makefile.PL', make, make test, make install. It linked using libz.dll.a in /usr/lib, which means that the dynamically loaded perl module "Compress/Zlib/Zlib.dll" depends on /usr/bin/libz.dll: cygcheck shows: ./site_perl/5.6.0/cygwin/auto/Compress/Zlib/Zlib.dll D:\cygwin\bin\cygwin1.dll D:\WINNT\System32\KERNEL32.dll D:\WINNT\System32\NTDLL.DLL D:\cygwin\bin\libz.dll D:\cygwin\usr\local\bin\libperl5_6_0.dll No need to rebuild zlib yourself, or to link statically. AFTER building and installing Compress:Zlib and Archive:Tar by hand, I built and installed CPAN. After than, 'perl -MCPAN -e shell' worked fine -- although, of course, it kept pestering me to install BUNDLE::libnet. Just another data point. I even tried the same test case that Neil Lunn used in his initial problem report: $ perl -MCPAN -e shell cpan> install Business::CreditCard .. various successful messages .. one of which is: CPAN: Compress::Zlib loaded ok .. .. It downloaded, built, and installed the CreditCard module without error. Perhaps the trick is that CPAN must be built/installed *AFTER* Compress::Zlib is built and installed. I dunno. Another possibility: I assume that Neil built Compress::Zlib and linked using a dll-import library (from zlib-1.1.3-1, but that's okay. Whatever). However, at runtime, perl/Compress::Zlib/Zlib.dll tried to load libz.dll and picked up a different version -- perhaps the one from X11R6. That'll cause problems every time. I don't know why, but Suhaib's libz.dll from his X11R6 distro and the official libz.dll's (1.1.3-1, 1.1.3-4) aren't compatible. To fix, make sure that /usr/bin appears before /usr/X11R6/bin in the path. (Or, link statically -- which is how Neil solved his problem). FWIW, I've got gcc-2.95.2-2 and binutils-20000722-1 installed. --Chuck -- Want to unsubscribe from this list? Send a message to cygwin-unsubscribe@sourceware.cygnus.com
