archive library build on 64bit architecture

[echorak]

I'm trying to build an archive library using the following script. It builds fine on 32-bit architectures, but when I try to build on a computer with 64-bit architecture I get this error message: /usr/bin/ld: warning: i386 architecture of input file `../lpdlib/lpdlib_byteswapio.a(system.o)' is incompatible with i386:x86-64 output

I'm extremely unfamiliar with library building commands and can't figure out how to specify the architecture of the input object files. Any clues?


Makefile:

FORT_COMP= pgf90
FORT_OPTS= -c -Mvect -Minfo -Munroll -Mnoframe -O2 -pc 64 -Mnofree -Mbyteswapio
ARCHIVE=ar rs
RANLIB =ls

LIB=lpdlib_byteswapio.a

SOURCE = cpart.f names.f polar.f random.f surfer.f system.f vform.f interpol.f polarst.f

$(LIB): $(SOURCE)
$(FORT_COMP) $(FORT_OPTS) $(?)
$(ARCHIVE) $(LIB) $(?:.f=.o)
$(RANLIB) $(LIB)
rm -f $(?:.f=.o)

Looks like you need a 64bit version of lpdlib_byteswapio.a

well, I know that much. But since I'm building this library myself, using the "ar" unix command, my question was how to specify to "ar" that this a 64-bit architecture.

This is just a guess: use the compiler to do the linking. I have a similar problem in C++. If I use the compiler to do the linking, it works. If I use ar or ld, it falls over in a heap.

If you're using the compiler, you can just specify -byteswapio
