I'm trying to link an application I need with a library libqtai that uses libqt and libGL (found in xfree/contrib/sgi-opengl.tar.bz2). When I try to link my application with the libraries, ex: $ g++ -I. -I /home/ljupco/CTK/include/ctk -Wall -O2 -D_HAS_QT -D_HAS_CURSES -o /home/ljupco/CTK/local/bin/CTKScript /home/ljupco/CTK/lib/CTKScript.o my_blocks.o my_translation_table.o -L/home/ljupco/CTK/lib -L/usr/local/qt/lib -L/usr/X11R6/lib -lctk /usr/local/qtai/lib/libqtai.a -lqt -lm -lcurses -lXmu -lXext -lSM -lICE -lGLU -lglut -lX11 -lGL I get error like: /usr/local/qtai/lib/libqtai.a(aiplot3d.o)(.text+0x5a26): undefined reference to `glPushMatrix@0' I see that libqtai needs: $ nm /usr/local/qtai/lib/libqtai.a|grep glPushMatrix U _glPushMatrix@0 (also $ nm /usr/local/qtai/aiplot3d.o |grep glPushMatrix U _glPushMatrix@0 ) While libGL provides: $ nm /usr/X11R6/lib/libGL.a |grep glPushMatrix 00000000 I ___imp_glPushMatrix 00000000 I __imp__glPushMatrix 00000000 T _glPushMatrix (also $ nm /usr/X11R6/static-lib/libGL.a |grep glPushMatrix 00004ab8 T _glPushMatrix ) Is this the names mangling thingy that c++ ("@parameters-derived-signature") does versus the way c does it ("_" before the name)? But I see that the header included from aiplot3d.cpp (and the headers it includes) have the "#ifdef __cpluplus extern "C" {" stuff. So where does @0 (in "U _glPushMatrix@0") come from? The metacompiler (moc) is used while creating the libqtai creating moc_aiplot3d.cpp. Can this be the problem? thanks in advance, -- Ljubomir Josifovski mailto:L.Josifovski@dcs.shef.ac.uk,blj01z@motorola.com http://www.dcs.shef.ac.uk/~ljupco -- Want to unsubscribe from this list?
