cross compiling and ld auto-import errors
Hi, I'm cross compiling a linux application to work on Windows using i586-mingw32msvc-gcc. The application is using Gtk and Gdk calls. I'm getting linking errors about glib that I don't know how to resolve. Here's the compile time output. i586-mingw32msvc-gcc demo.o dthread.o callbacks.o interface.o hsv2rgb.o polar.o rebin.o scope.o seismograph.o sgram.o spin.o vbargraph.o waterfall.o /usr/local/win32gtk2.4/Runtime/lib/iconv.dll /usr/local/win32gtk2.4/Runtime/lib/intl.dll /usr/local/win32gtk2.4/Runtime/lib/libatk-1.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgdk-win32-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgdk_pixbuf-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libglib-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgmodule-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgobject-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgthread-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libgtk-win32-2.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libpango-1.0-0.dll /usr/local/win32gtk2.4/Runtime/lib/libpangowin32-1.0-0.dll -lm -o demo polar.o:polar.c:(.text+0x2a5): variable '_g_thread_functions_for_glib_use' can't be auto-imported.

Re: cross compiling and ld auto-import errors
Never mind, I solved it. There were a few g_mutex_lock/unlock calls in the code and that seemed to be the problem. I replaced them with gdk_threads_enter() and gdk_threads_leave() (after ensuring that g_threads_init() and gdk_threads_init() were both called) and the linker was much happier. -Bethany On Fri, 2007-06-01 at 10:43 -0400, Bethany Seeger wrote: > Hi, > > I'm cross compiling a linux application to work on Windows using > i586-mingw32msvc-gcc. > > The application is using Gtk and Gdk calls. > > I'm getting linking errors about glib that I don't know how to resolve. > Here's the compile time output. > > i586-mingw32msvc-gcc demo.o dthread.o callbacks.o interface.o > hsv2rgb.o polar.o rebin.o scope.o seismograph.o sgram.o spin.o > vbargraph.o > waterfall.o /usr/local/win32gtk2.4/Runtime/lib/iconv.dll > /usr/local/win32gtk2.4/Runtime/lib/intl.dll > /usr/local/win32gtk2.4/Runtime/lib/libatk-1.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgdk-win32-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgdk_pixbuf-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libglib-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgmodule-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgobject-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgthread-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libgtk-win32-2.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libpango-1.0-0.dll > /usr/local/win32gtk2.4/Runtime/lib/libpangowin32-1.0-0.dll -lm -o demo > polar.o:polar.c:(.text+0x2a5): variable > '_g_thread_functions_for_glib_use' can't be auto-imported.

(Somebody might think you are referring to the dll files themselves here.) The Win32-targeted linker looks for also libfoo.dll.a, not just libfoo.a when it encounters -lfoo. At least natively, presumably also when cross-compiling. --tml ___ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
