I tried building on linux at the time but couldn't quite get it to work. After another quick look today it seems your problem may be solved by adding --shared to LDDLFLAGS. For my install( and maybe yours ) Inline seems to be telling gcc to build an executable when it should be telling it to build a shared lib ( Undefined symbols: _main ). With --share added the error messages reduce to Can't load '/tmp/_Inline/lib/auto/GLFW_ae09/GLFW_ae09.so' for module GLFW_ae09: /tmp/_Inline/lib/auto/GLFW_ae09/GLFW_ae09.so: undefined symbol: XF86VidModeQueryExtension at /usr/lib/perl/5.8/DynaLoader.pm line 225. at /usr/local/share/perl/5.8.2/Inline.pm line 500 which seems to be because libXxf86vm is not being included. Can not for the life of me manage to convince gcc to include it. > On 10/3/05 10:50 AM Brian Hammond wrote: > >Hello - > > > >This is my first time using Inline. > > > >I am trying to autowrap a C library called GLFW using Inline C (0.44) on > >Mac OS X.
