Build is happening by default with g++ instead of arm compiler?

I am encountering a very strange issue. I am building my source for ARM with ARM compilers. I modified CXX field in makefile to build using arm-linux-gnueabihf-g++ instead of g++ but while building its still taking g++. Can someone please help me here? MY makefile has the following entry

CXX         = g++ 

I modified it to look as follows

CXX         = arm-linux-gnueabihf-g++ 

Shouldn’t the build happen using arm-linux-gnueabihf-g++ instead of g++?

Answer

It’s impossible to know why you’re seeing what you’re seeing without the rest of your build system, but here’s some general advice:

Don’t edit the makefile; pass the value you want on the command line:

make CXX=arm-linux-gnueabihf-g++ <whatever your normal args are>

Command line values override those set inside the file, and usually get passed down to nested makefiles and override all the other confusing stuff that can complicate this.

If that doesn’t work, check there isn’t a configure script, or something else that you ought to be using instead.
