Cross GCC problem with profiling tools

[nivas]

Hi,

I am trying to build a cross compiler targeting a MIPS (or whatever) for a linux-i386 host. I have managed to build a working toolchain (gcc, binutils, newlib, gdb) but i have a problem with the profiling tools. Specifically, when i am compiling program with -pg to enable profiling a link error is produced because the linker finds an udefined reference to _mcount. A similar error is produced when i want to link a program compiled for gcov. I have build gprof correctly but this does not seem to change the situation.

Any help????

Thanks!!

Re: Cross GCC problem

gprog manual states:

The mcount routine, included in the profiling library, is responsible for
recording in an in-memory call graph table both its parent routine (the child)
and its parent’s parent.

This means that you will need cross profiling library too.
