[Open64-user] Problem building 64-bit compiler

[Evan D. <dri...@cs...>]

I'm trying to build a 64-bit version of the compiler. The docs say "If 
you are building on an 386/x86_64 system, the target will default to 
building a 32 bit compiler with 32 and 64 bit libraries and you do not 
have to use this option", and so I figured I'd pass 
"--target=ia64-unknown-linux-gnu" to 'configure'.

However, when I do this, 'configure' runs fine but then 'make' reaches 
an error relatively quickly:

g++   -m32 -mno-sse2 ...  -o ipfec_targ_gen ...
/usr/bin/ld: i386:x86-64 architecture of input file 
`/tmp/driscoll/open64-build/osprey/.././osprey/targdir/libkapi/libkapi.a(kapi_general.o)' 
is incompatible with i386 output
...
<several of the same errors with different files>
...
make[3]: *** [ipfec_targ_gen] Error 1
make[3]: Leaving directory 
`/tmp/driscoll/open64-build/osprey/targdir/targ_info'

In other words, even though I want a 64-bit target, it seems to be 
linking with -m32 anyway.

Am I doing something wrong, or is this a bug in the build scripts?
