[Gnash] multilib 64-bit users

Thu, 18 May 2006 12:41:53 -0700

Since I have been unable to build gnash for some reason or another, I was wondering if there were any other 64-bit multilib users using gnash. By multilib 64-bit users I mean users with 64-bit Linux systems with both versions of any given library (i386, 32-bit and x86_64, 64-bit). After much struggle and trying to build other programs like Quake 3 sources or some OpenGL demos, its been apparent that the configure script for gnash for some reason when configuring for a 64-bit system tries to link (the plugin) to the 32-bit libGL.so spiting the error:

/usr/lib/libGL.so: could not read symbols: File in wrong format


when building libgnashplugin.so

I have the nvidia driver installed for both 32-bit and 64-bit. Here's the line for g++ when building libgnashplugin.so:

g++ -shared -nostdlib /usr/lib/gcc/x86_64-redhat-linux/4.1.0/../../../../lib64/crti.o /usr/lib/gcc/x86_64-redhat-linux/4.1.0/crtbeginS.o  .libs/plugin.o .libs/npn_gate.o .libs/npp_gate.o .libs/np_entry.o  -Wl,--rpath -Wl,/home/gianni/Programas/gnash/gnash/backend/.libs -Wl,--rpath -Wl,/home/gianni/Programas/gnash/gnash/server/.libs -Wl,--rpath -Wl,/home/gianni/Programas/gnash/gnash/libgeometry/.libs -Wl,--rpath -Wl,/home/gianni/Programas/gnash/gnash/libbase/.libs -Wl,--rpath -Wl,/usr/local/lib -L/usr/lib -L/usr/lib64 -L/home/gianni/.mozilla/plugins -lSDL /usr/lib64/libGL.so -lGLU /usr/lib64/libgtkglext- x11-1.0.so /usr/lib64/libgdkglext-x11-1.0.so -lgtk-x11-2.0 -lgdk-x11-2.0 -lpango-1.0 -lcairo -latk-1.0 -lglib-2.0 -lxml2 /usr/lib64/libz.so -lz -ljpeg -lpng -logg ../backend/.libs/libgnashbackend.so ../server/.libs/libgnashasobjs.so ../server/.libs/libgnashserver.so ../libgeometry/.libs/libgnashgeo.so ../libbase/.libs/libgnashbase.so -lSDL_mixer -lrt -lX11 -lXi -lXmu -L/usr/lib/gcc/x86_64-redhat-linux/4.1.0 -L/usr/lib/gcc/x86_64-redhat-linux/4.1.0/../../../../lib64 -L/lib/../lib64 -L/usr/lib/../lib64 -lstdc++ -lm -lc -lgcc_s /usr/lib/gcc/x86_64-redhat-linux/4.1.0/crtendS.o /usr/lib/gcc/x86_64-redhat-linux/4.1.0/../../../../lib64/crtn.o  -Wl,-soname -Wl, libgnashplugin.so -o .libs/libgnashplugin.so

If corrected the error in the above line, then there is apparently a problem for libz (-lz), and others which are again seeked for under /usr/lib instead of /usr/lib64:

/usr/bin/ld: skipping /usr/lib/libz.so incompatible while seeking -lz
/usr/bin/ld: skipping /usr/lib/libz.a incompatible while seeking -lz
/usr/bin/ld: skipping /usr/lib/librt.so incompatible while seeking -lrt
/usr/bin/ld: skipping /usr/lib/librt.a incompatible while seeking -lrt
/usr/bin/ld: skipping /usr/lib/libm.so incompatible while seeking -lm
/usr/bin/ld: skipping /usr/lib/libm.a incompatible while seeking -lm
/usr/bin/ld: skipping /usr/lib/libc.so incompatible while seeking -lc
/usr/bin/ld: skipping /usr/lib/libc.a incompatible while seeking -lc

Anyone else having such problems? If the configure script can detect pkg-config, wouldn't it be better to use pkg-config instead for Linux systems to avoid all these issues? (just an idea, though)
