Re: How does one compile 64-bit executables on HP-UX PA-RISC?

I have an HP C3600 workstation

which is fitted with 552 MHz PA-8600 PA-RISC CPU (64-bit) and 8 GB RAM.

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

drkirkby@hpbox:~$ gcc -m64 test.c
cc1: error: unrecognized command line option "-m64"

Can anyone tell me how to build 64-bit binaries with gcc on this machine?
GCC for the PA isn't runtime switchable between 32 and 64 bit binaries.

Thanks - that's a bit annoying. I'm used to using -m64 on Solaris.


ie, however GCC was initially configured is the only way it'll generate
code on the PA.

What does gcc -v report?

There are two versions on my machine.


drkirkby@hpbox:~$ gcc -v
Using built-in specs.
Target: hppa1.1-hp-hpux11.11
Configured with: /tmp/gcc-4.3.3.tar.gz/gcc-4.3.3/configure --host=hppa1.1-hp-hpux11.11 --target=hppa1.1-hp-hpux11.11 --build=hppa1.1-hp-hpux11.11 --prefix=/opt/hp-gcc-4.3.3 --with-gnu-as --without-gnu-ld --enable-threads=posix --enable-languages=c,c++ --with-gmp=/proj/opensrc/be/hppa1.1-hp-hpux11.11 --with-mpfr=/proj/opensrc/be/hppa1.1-hp-hpux11.11

Someone said the HP install is buggy, and produced this one. So I do have two installs of gcc.

drkirkby@hpbox:~$ gcc -v
Using built-in specs.
Target: hppa2.0w-hp-hpux11.11

Thread model: posix
gcc version 4.3.4 (GCC)


I thought the latter, with the hppa2.0w-hp-hpux11.11 might have created 64-bit binaries, but still sizeof(long) == 4, so I assume not.
