	Hi,
	This is probably a really stupid question, but I was unable to find an
answer to it, despite looking though both GCC manuals (and install
notes), and searching the Dejanews. I have a feeling that the answer is
right in front of me, but I can't find it...

	Here is what happens. Some C++ code I am compiling has to be linked
against libstdc++ (obviously), which is an archive of N32 objects.
Trouble is, the object files I am generating, are all O32. When I try to
pass what I *THINK* is the right flag to g++ (-Wa,-n32), assembler
complaint and does not generate ANY code.

Here is the command line I used to generate O32 objects:

g++ -c -Wall -DTRUE_SIMULATION
-I/usr/mmedia/drubenst/projects/cc/code/imp2/include.iris4d
-I/usr/mmedia/drubenst/projects/cc/code/imp2/
-I/usr/mmedia/drubenst/projects/fec/code -I/usr/freeware/lib/g++-include
/usr/mmedia/drubenst/projects/cc/code/imp2/pkt.C -o
/usr/mmedia/drubenst/projects/cc/code/imp2/obj.iris4d/pkt.o

	This one works, but the objects it produces cannot be linked with
libstdc++.

When I include the "-Wa,-n32" flag right after "g++", the assembler
spits out a large number of messages similar to the following:

as: Error: /usr/mmedia/drubenst/projects/cc/code/imp2/pkt.C, line 1:
stmt extends past logical end
      .globl __11_ios_fieldsRC11_ios_fields .text

	Does anyone have any idea of how I could force the compiler and
assembler to generate the N32 objects?

	Thanks,

I think your trouble is with which assembler is invoked for which ABI.
For n32, gcc needs to invoke the SGI assembler, for o32 it somehow needs
the gnu assembler I think. Toy a bit with that. Also, I think the
correct flag for gcc2.8.x is -mabi=n32 if you want n32 output.
