Segmentation Fault: OpenGLES 2.0 emulator 1.2.0 linux 64-bit

Hi there,

I have installed Mali OpenGLES 2.0 emulator v 1.2.0 on my Ubuntu 10.10 (64-bit) machine. I am able to successfully build the cube example program available with the emulator. However, when I try to run the program, I get a segmentation fault. Here is GDB backtrace:


(gdb) r
Starting program:~/ARM/Mali_Developer_Tools/OpenGL_ES_2_0_Emulator_1.2.0/example/cube/cube
warning: the debug information found in "/lib/ld-2.12.1.so" does not match "/lib/ld-linux.so.2" (CRC mismatch).

I have got ATI Radeon HD 5670 graphics card with driver version 8·78.3 (OpenGL version 4.0.10237).

    Hy Anthony,

    I have got the same problem, but including the compile switch -m32 does not fix the problem.

    The gdb output is similar.

    I do not use the fglrx driver, but the mesa driver that comes with Ubuntu

    Thanks

    I also get segmentation fault even after using -m32 flag.

    Hy Anthony,

    Thank you for your reply. I installed the package you mentioned, but the cube demo still stops with the same fault. GDB output looks still the same.
