Hi Eljay,

Yes, I have tried -g and -ggdb options and they do work, but I was
wondering
why the other options does NOT work.

Hi Nirav,

Have you tried this...

g++ -mdll -DBUILD_DLL -O3 -c -fno-exceptions -g foo.cpp

...?

-gxcoff is only meaningful on AIX.

The problem with -gcoff sounds like a bug somewhere.  I doubt anybody
cares very much, since COFF debugging information is very limited.

-gdwarf was removed recently, since DWARF 1 has been replaced by DWARF
2.  -gdwarf-2 still exists.

debugging switches/options with x86 target?

[nirav.dalal]

Hi,

I'm having issues with compiling gcc using debugging switches/options
with x86 target.

I have tried debug switches as under:

>gcc -mdll -DBUILD_DLL -O3 -c -fno-exceptions -gxcoff foo.cpp
cc1plus.exe: warning: `xcoff': unknown or unsupported -g option
cc1plus.exe: warning: `xcoff': unknown or unsupported -g option
cc1plus.exe: warning: `xcoff': unknown or unsupported -g option


>gcc -mdll -DBUILD_DLL -O3 -c -fno-exceptions -gcoff foo.cpp
C:\DOCUME~1\DalalN\LOCALS~1\Temp/cc6baaaa.s: Assembler messages:
C:\DOCUME~1\DalalN\LOCALS~1\Temp/cc6baaaa.s:2819: Fatal error: C_EFCN
symbol out of scope


>gcc -mdll -DBUILD_DLL -O3 -c -fno-exceptions -gdwarf foo.cpp
cc1plus.exe: warning: `dwarf': unknown or unsupported -g option
cc1plus.exe: warning: `dwarf': unknown or unsupported -g option
cc1plus.exe: warning: `dwarf': unknown or unsupported -g option

Why are these options unsupported? Am I missing something?
Any help on this problem is appreicated.

The GCC version I'm using is:
>gcc --version
