Problems with GCC 2.95.2 on HP-UX 11.00

Problems with GCC 2.95.2 on HP-UX 11.00

[Fleischer, Karsten (K.)]

Hi,

I've configured GCC with the option --with-gnu-as and was able to bootstrap
and install. The detected target is hppa2.0w-hp-hpux11.00.

Then I got problems with some header files then, namely <sys/_size_t.h> and
<sys/unistd>.
I copied those to
/usr/local/lib/gcc-lib/hppa2.0w-hp-hpux11.00/2.95.2/include/sys and edited
them manually.

In _size_t.h I replaced the line

	typedef unsigned long size_t;

with

	#ifndef __SIZE_TYPE__
	#define __SIZE_TYPE__ long unsigned int size_t
	#endif
	#ifndef _GCC_SIZE_T
	#define _GCC_SIZE_T
		typedef __SIZE_TYPE__ size_t;
	#endif

and in unistd.h I changed the prototype

	extern int pthread_atfork(void (*prepare)(), void (*parent)(),
						void (*child)());

to

	extern int pthread_atfork(void (*prepare)(void), void
(*parent)(void),
						void (*child)(void));

Then I tried to compile our (huge) application and got a bunch of error
messages like these:

/var/tmp/cc4mHGtZ.s: Assembler messages:
/var/tmp/cc4mHGtZ.s:69: Error: invalid operands
...

I could get rid of these by compiling with -march=1.0 or -march=1.1.

After linking the program I tried to run it from DDD and got the following
messages:

warning: unable to write __d_pid
warning: Suggest linking with /opt/langtools/lib/end.o
warning: GDB will be unable to track shl_load/shl_unload calls
Unable to read __dld_flags

Questions -
1) How do I compile for hppa2.0 architecture? (I have built the latest
binutils, but that doesn't change anything)
2) What's wrong with dld.sl? (I tried to link statically, but some libraries
are only available as shared libs)

Regards,
Karsten

gcc-2.95 does not support hpux11.  You're seeing one of several known
problems.

If you want hpux11 support you'll need to wait for GCC 3.0.

Similarly, you probably need a newer version of gdb for hpux11.

The bad news is that GCC 2.95.2 doesn't support HP-UX 11.00.  It may
even appear to work, but you'll end up having problems as you
described.  I believe development snapshots are supposed to support
HP-UX 11.00, but the HP-UX port hasn't bootstrapped lately :-(

I should have known this before our sysadmin updated from 10.20 to 11.00 :-(
Nah, doesn't matter. I'll continue developing on Sun and try out the
snapshots on HP-UX from time to time.

Anyway, thanks.
