Hi!
I've tried to compile vrwave 2.0 (Java VRML viewer with GL native
engine) and had to find out that the shared lib (the engine)
was not compiled correctly. On startup of vrwave (a VRML viewer)
I got the following error message:
/usr/lib/libgejc.so: undefined symbol: XMesaCreateVisual (libgejc.so)
OGLCanvas. error: unable to load 'gejc' shared library.
You'll get no display output. Please check whether
- libgejc.so is in your LD_LIBRARY_PATH (Unix)
Also I tried a testcompile of the library as if it was a program:
gcc -o libgejcon-mesa.so gejcon-mesa.o gejimpl.o ge3d_mesa.o vrwbuild.o asmooth.o
triangulate.o vrwpick.o -L/usr/X11R6/lib -lGLU -lGL -lXext -L/usr/X11/lib -lXmu -lX11
-lm
/usr/lib/gcc-lib/i586-mandrake-linux/2.95.3/crt1.o: In function `_start':
/usr/lib/gcc-lib/i586-mandrake-linux/2.95.3/crt1.o(.text+0x36): undefined reference to
`main'
gejcon-mesa.o: In function `Java_iicm_ge3d_OGLCanvas_setContext':
gejcon-mesa.o(.text+0x614): undefined reference to `XMesaMakeCurrent'
gejcon-mesa.o: In function `Java_iicm_ge3d_OGLCanvas_swapBuffers':
gejcon-mesa.o(.text+0x8ab): undefined reference to `XMesaSwapBuffers'
gejcon-mesa.o: In function `createMesaBackBuffer':
gejcon-mesa.o(.text+0xd40): undefined reference to `XMesaCreateVisual'
gejcon-mesa.o(.text+0xd6e): undefined reference to `XMesaCreateContext'
gejcon-mesa.o(.text+0xda6): undefined reference to `XMesaCreateWindowBuffer'
collect2: ld returned 1 exit status
After changing the libGL.so.1 link and recompiling the lib all was fine:
ln -sf libGL.so.1.2.030300 libGL.so.1 (in /usr/X11R6/lib)
So the wrapper does either not seem to work correctly or the program
as not coded correctly (see gejcon.c in the VRwave/native directory
of the archiv which can be found on http://www.iicm.edu/vrwave).
I've added a spec file for mandrake cooker but this one requires
Java jdk 1.1.x to be installed (can be downloaded from blackdown.org).
The netscape plugin did not compile for me as I don't have the Netscape
SDK (it this available for Linux ?).
Anyway I've added a modified patch, the spec file for vrwave and an png
icon but there was an error message (I had to convert it from gif you
know the reasons...):
rpm -bi --short-circuit SPECS/vrwave.spec
Unknown icon type: vrwave.png
Any help is appreciated.
Best regards,
Reinhard Katzmann
