Hi Reza,<br>
<br>
Can you perhaps try running some of these tests individually which<br>
might give us a bit more information about what could be going wrong<br>
for you?<br>
<br>
If you cd into the tests/conform directory then if you have already<br>
run make test before then you should see wrapper scripts for all of<br>
the individual tests so you can e.g. run ./test-primitive<br>
<br>
When run this way, the script also prints out how that test can also<br>
be run individually under the gdb debugger. If it looks like the test<br>
is crashing with a segfault then it would also help to run the test<br>
under gdb so we can see a backtrace showing where the crash is<br>
happening.<br>
<br>
When building Cogl, it could be good to pass --enable-debug and<br>
CFLAGS="-g3 -O0" to ./configure if you aren't already, which could<br>
improve the diagnostics we can get.<br>
<br>
Kind regards,<br>
Robert<br>
