From: Mark Hahn Date: 2001-12-24T07:41:31+09:00 Subject: [ruby-talk:29381] x.dll versus x.lib in mswin32 ruby I've built mswin32 ruby and now I'm trying to build ruby/gtk. When I run extconf.rb I get an error saying it can't find a routine in a library, even though I have a dll with that entry point in the path. It appears that mkmf.rb is looking for x.lib instead of x.dll: def append_library(libs, lib) if /mswin32/ =~ RUBY_PLATFORM lib + ".lib " + libs else "-l" + lib + " " + libs end end Does this mean that I cannot use DLL's in mswin32 Ruby? This doesn't make any sense.
