Hi,
I am a totally new user to QNX. I have a very simple question that I
am trying to find an answere to. If I develop an application in a QNX
6.2.1 environment, will they run any differently in a QNX 6.3
environment?
What difference does it make to compile a peice of code in 6.2.1
environment instead of a QNX 6.3 environment. If anyone can post an
answere to these I would really appreciate it. Thanks
Azam
In QNX 6.3, you have GCC 3.x available. QNX 6.21 still has an
old GCC 2.x compiler. You can run programs built under QNX 6.21
on QNX 6.3. To go the other way, you may need some .so files
from 6.3. Or you can still build using the GCC 2.x compilers
on 6.3.
QNX 6.3 has OpenGL, but it’s not hardware accelerated on
x86 desktops. It’s basically Mesa, the open source OpenGL
implementation. So if you port Quake, it’s going to be slow.
QNX 6.3 has a later version of the Eclipse IDE, which is
said to work much better than the one in QNX 6.21.
We backed off from QNX 6.3 to QNX 6.21NC, and it only took a few
hours to have everything running on 6.21NC. The differences
aren’t that big.
