David,
gcc -g -O2 -Wall -lm -o executable object object object object object
object ... -lpthread
I also tried the most simple example imaginable, much like you example.
The Makefile specifies the CCLD macro as gcc:
CC = gcc
CFLAGS = -g -O2 -Wall
COMPILE = $(CC) $(DEFS) $(INCLUDES) $(AM_CPPFLAGS) $(CPPFLAGS)
$(AM_CFLAGS) $(CFLAGS)
CCLD = $(CC)
LINK = $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(LDFLAGS) -o $@
When I do:
# ar -tv /usr/ccs/lib/libm.a
I get

However, if I do:
# ar -X64 -tv /usr/ccs/lib/libm.a
I get nothing. Am I just missing the 64-bit version of libm.a?
Thanks in advance!

Re: [tbox-l] libm.a not a COFF file
libm.a is a system library which contains XCOFF files. You'll need to
look
at the compile or link command being executed which is producing this
error
to see how it is arriving at this error. Typical simple usage would be:
$ gcc myprog.c -lm -o myprog
where the "-lm" says to link with the "libm.a" library.
Somehow you are using incorrect link option(s) in some way to give you
that message. So find the 'gcc' or the 'ld' command line which produced
the error, and look at how it is trying to use libm.a.
