You can link against static archives when using 'pass_all' instead of 'file_magic ^x86 archive import|^x86 DLL' to recognise dependent libraries in libtool (change in libtool.m4). > [*] We have a machine that could serve as an autobuilder for > Cygwin packages, so once we make SableVM buildable and working > under Cygwin it should be possible to ensure every new version > still works. -- =^..^= -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
