How to specify GCC version in make file

Hi,

I am building a C++ application using GCC and am trying to create a make file.
On my QNX system there are two versions of the compiler 2.95.3 and 3.3.5.

When I do a gcc -dumpversion I always get 2.95.3 as the compiler version.

How do I specify in my make file that the GCC compiler to  use should be 3.3.5?

Regards,
Lakshmi.

Re: How to specify GCC version in make file

If you're using QNX mkfiles project, they are set up to use a GCC_VERSION macro.

e.g

make GCC_VERSION=3.3.5

If you're using a standard makefile project:

CC=ntox86-g++-3.3.5

helloworld: hw.cc 
    ${CC} hw.cc
