You'll note that those missing libraries contain "msw", i.e. "Microsoft Windows", which us Linux users certainly shouldn't be trying to link against. collect2: ld returned 1 exit status > > a search on google brings a few pages, however I still can't figure > out how to make it work. > > Here's what libraries I have that contain 'wx', I've no idea how to > get the missing ones. > > $ find /usr -name '*wx*so' > /usr/lib/libwxsvg.so > /usr/lib/libwx_gtk2u_ogl-2.8.so > /usr/lib/libwx_gtk2u_xrc-2.8.so > /usr/lib/libwx_gtk2u_richtext-2.8.so > /usr/lib/libwx_gtk2u_gizmos-2.8.so > /usr/lib/libwx_gtk2u_fl-2.8.so > /usr/lib/libwx_gtk2u_html-2.8.so > /usr/lib/libwx_baseu_net-2.8.so > /usr/lib/libwx_gtk2u_aui-2.8.so > /usr/lib/libwx_gtk2u_stc-2.8.so > /usr/lib/libwx_baseu_xml-2.8.so > /usr/lib/libwx_gtk2u_core-2.8.so > /usr/lib/libwx_gtk2u_gizmos_xrc-2.8.so > /usr/lib/libwx_gtk2u_qa-2.8.so > /usr/lib/libwx_gtk2u_adv-2.8.so > /usr/lib/libwx_baseu-2.8.so > /usr/lib/libwx_gtk2u_svg-2.8.so > /usr/lib/libwx_gtk2u_gl-2.8.so > /usr/lib/libwx_gtk2u_plot-2.8.so > > Please help ! > > David. > I see from this you're on wx 2.8 for GTK, and that's okay, we just need to remove those non-Linux libraries, and I'm afraid that involves some hacking (I'm working on a patch to clean this up, I need to get it to the list): You'll need to edit wxcore/Setup.hs thus: On or around line 51 you'll see: > let extra_wx_libs = if ver == "9" [BUNCH OF LIBRARY INCLUDES] Now I use wx 2.9 for GTK, and I've replaced the include list with these: > [ "-lwx_gtk2u_xrc-2.9", "-lwx_gtk2u_stc-2.9", "-lwx_gtk2u_aui-2.9" > , "-lwx_gtk2u_ribbon-2.9", "-lwx_gtk2u_propgrid-2.9", "-lwx_gtk2u_richtext-2.9" > , "-lwx_gtk2u_gl-2.9", "-lstdc++"] Hopefully you can adjust this for your needs, and it would be great if you could send your list back so I can include it in my patch. For the curious: Wondering how the library can still compile with some includes missing? (I believe, perhaps someone can confirm...) If you inspect some of the .cpps under wxcore/src/cpp/ you'll find they do a bunch of ifdefs (for example ifdef wxUSE_MEDIACTRL). Where do these defines come from? Well in Setup.hs you'll find this: > (readProcess "wx-config" ["--libs", "--cppflags"] "") And that "cppflags" flag will print out (or in our case, on Linux, not print out) things like (wxUSE_MEDIACTRL), these are passed to "ccOptions" (from Distribution.InstalledPackageInfo), and the build system then passes these to the CPP linker.
