I'm working on the development of a Qt/OpenGL software, primarily
intended for Linux, but with some hopes also for an Irix-port.
On Linux, it works fine, but on Irix it core dumps, giving various
excuses such as segmentation fault, illegal instruction ... In both
cases I'm using gcc 2.95.2. Since not a single instruction of my code
appears to be executed I've been trying to trace the loading process.
It gets to the point where rld.debug says:
2759976: 09:09:53 vm: call_init: calling initialization code of "vm" --
0x100a6f38 base aout marrk 1
2759976: 09:09:53 vm: execute_all_init_sections: finished running inits
Segmentation fault (core dumped)
I've checked other Qt/OpenGL programs that work, and there the loading
process instead continues as follows:
2706057: 12:14:24 example: call_init: calling initialization code of
"example" -- 0x10013568 base aout marrk 1
2706057: 12:14:24 example: execute_all_init_sections: finished running
2706057: 12:14:24 example: dlopening -------- libGL.so mode 0x1 version
(null) l_flags 0x0 category 0x1 LIBDL_DLOPEN
2706057: 12:14:24 example: reference_count for /usr/lib32/libGL.so is 1
2706057: 12:14:24 example: do_dlopen_dependencies ref count for ...
I've been trying various compilation and loading flags, but this has
only resulted in different error messages before the core dump.
Any ideas, anyone?
