There is a file called default along with a 2.95.3 and 3.3.5 directory.
The contents of the default file are ‘DIR=2.95.3’
I suspect changing that to 3.3.5 will automatically have qcc call 3.3.5
This is on a self hosted system (not the Momentics IDE). In the IDE, there is a specific setting you can change to use 3.3.5 as the default compiler.
Personally, I manually specify the compiler in my CFLAGS option in my Makefile. That way I always know I’m using the 3.3.5 compiler in case someone forgets to change that file on a new install etc.
