4.3: Verifying the Operation of the Cross Toolset

In order to insure that the cross-compiler is invoking the correct subprograms (like as and ld), one can test assemble a small program. When in verbose more, gcc prints out information showing where it found the subprograms it invokes. Place the following function in a file named f.c:

int f( int x )
{
  return x + 1;
}

Then assemble the file using a command similar to the following:

m68k-rtems-gcc -v -S f.c

Where m68k-rtems-gcc should be changed to match the installed name of your cross compiler. The result of this command will be a sequence of output showing where the cross-compiler searched for and found its subcomponents. Verify that these paths correspond to your <INSTALL_POINT>.

NOTE: One of the most common installation errors is for the cross-compiler not to be able to find the cross assembler and default to using the native as. This can result in very confusing error messages.
