If I use gcc -m64, I get an error.

Can anyone tell me how to build 64-bit binaries with gcc on this machine?

GCC on HP-UX PA-RISC uses seperate compilers for 32 and 64 bit modes
because 32 bit mode is SOM based and 64 bit mode is ELF based. You can
get pre-built GCC compilers from http://www.hp.com/go/gcc and if you do
then you would need to download and install 2 different compilers to
generate both 32 and 64 bit code. The 32 bit compiler from this
location installs as /opt/hp-gcc/bin/gcc and the 64 bit compiler
installs as /opt/hp-gcc64/bin/gcc. If you are building GCC yourself you
need to build GCC with a target like 'hppa64-hp-hpux11.23' to build a
compiler that can generate 64 bit objects (but it will not be able to
generate 32 bit objects). If you build with a target such as
'hppa2.0w-hp-hpux11.23' then you will get a compiler that can generate
32 bit objects but not 64 bit objects.

Thank you Steve.
I recall now I do have both, but I know there was some bug in one of the
compilers, which was avoided when Dennis Clarke built the compiler on my machine
some months ago (I forget the exact details). But I'll have to look at building
these again. At least now I know what I am aiming for, and not hunting for a
compiler switch, which is what I was doing before!
