Hi.
I’ve ran into problems running PowerVR SDK Demos after I upgraded my distro to Ubuntu 9.04. I had no problems whatsoever with my old Hardy Heron (8.04) version.
I would guess there are some compatibility problems between PowerVR SDK provided EGL and GLES libraries and g++ installed in the system.
What happens is that whenever EGL and GLES library is linked with an application the application just dies with shared library event.
Following script illustrates what happens when a really simple application is compiled with and without EGL and GLESv2 libraries:

And here is the application code:

:~/workspace/test1$ cat main.cpp
#include <iostream>
using namespace std;
int main(int, char**)

cout << "main() - called." << endl;
return 0;
}
:~/workspace/test1$ exit

Does anybody have any ideas about what's going on? Should I use an earlier version of g++ or is there going to be a recompilation of PowerVR SDK libraries that would work with g++ 4.3.3? Or is the root cause actually something completely unrelated?
I've tried this with PowerVR SDK versions 2.03.23.1162 and 2.04.24.0811 with identical results.
Cheers,
