I am using 6.3.2 and I want to change the default gcc from 2.95.3 to 3.3.5 but I can’t seem to do it. I tried editing this file:
/usr/qnx632/host/qnx6/x86/etc/qcc/default
I changed it to DIR=gcc/3.3.5/
But gcc -v still gives 2.95.3…am I missing something?
Changing that file changes what qcc uses by default not gcc.
I think if you do a “which -laf gcc” it’s just a link to the 2.9.5 version of gcc, so I guess you can just change it to point at the 3.3.5 version. But you may have to change a bunch of links…maybe there is a better way??? Sorry, I always use qcc to compile for QNX.

Okay, how does one make qcc the default compiler?
qcc should be the default compiler, since qcc internally will call gcc
^^
Okay, this becoming circular. How do I make qcc call gcc 3.3.5 instead of 2.95.2?
JCT,
In /usr/qnx630/host/qnx6/x86/etc/qcc/gcc
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.

That did it. Thanks all!
try calling:
qcc -V3.3.1,gcc_ntox86 -set-default
where, gcc_ntox86 is your target system (e.g. gcc_ntoppcbe, …)
This should automatically change all needed files to your defaults.
oh yeah, otherwise, if you do not wish tu take default,
just add the
-V3.3.1,gcc_ntox86
to your compiler command ^^
That worked, thanks all!
Or maybe not.
gcc -v
gcc version 2.95.3
gcc -v will always 2.95.3 as long as you do not move the symlink
call qcc with apropriate parameters
