Probably mips-elf-gcc put "C:\cygwin\tmp\main.c" in main.o as source file
name but objdump is fooled thinking that (because it does not start by '/'
or '\') "C:\cygwin\tmp\main.c" is a relative path name :-(

Try to use cygpath when calling gcc to avoid drive letters in the source
path names and you should not have any more problem; as you ported gcc
yourself (I think) you could also patch gcc so that is calls the proper
cygwin API function to convert its input path names to cygwin syntax :-)

Mix Path Name Problem

Hi,

I notice that cygwin can handle path name correctly. For example,

In a DOS prompt window,

cd \
gcc -g -c C:\cygwin\tmp\main.c
objdump -DxlS main.o

cygwin can find the source in C:\cygwin\tmp\main.c correctly.

Now I have make a cross GNU tool chain including binutils-2.10
and gcc-2.95.2 for MIPS.

In a DOS prompt window,

cd \
C:\tools\mips-elf-gcc -g -c C:\cygwin\tmp\main.c
C:\tools\mips-elf-objdump -DxlS main.o

The mips-elf-objdump trys to find the source in
/cygdrive/c/C:\cygwin\tmp\main.c

I have tried to find the answer in binutils-20000722-1.src.tar.gz
which should be the source cygwin used to build binutils. But
I can't find any clue. Please tell me the magic. Thank you!

Regards,
Tim Ouyang
