setting the environment for the m68k-elf-gcc toolchain

Hi

I'm trying to write an ADC driver for my ColdFire Board that runs on
uClinux. For this, i have installed the toolchain : m68k-elf-gcc from
the uClinux site.

My question, though pretty elementary is, how can I be sure that when
i run my make file, it is invoking the m6k-elf-gcc compiler than the
regular standard gcc compiler ??

I have added the uClinux toolchain to the PATH variable. What can I do
to check that this compiler is being invoked for  the compilatoin ???

cheers

It's all in your makefile. Did you write it yourself, or did you copy
one from somewhere else ?

The convention when writing makefiles is to define the compiler to use
in the "CC" variable.
i.e somwhere in your makefile you will have
CC=m68k-elf-gcc

To invoke the compiler in the makefile you will use
$(CC)  -c file.c -o file.o

This way it is easy to change the compiler you use to build the code.

Each command is normally echoed to the console as the makefile issues
it. If you are running the makefile through  an IDE, it should send
these messages to a log file, which should be viewable in the IDE.
