Building gcc on HPUX 11.00

Building gcc on HPUX 11.00

[Eric Gilmore]

I've been trying to compile gcc on an HP C110 workstation (PARISC 1.1 
architecture) on which I recently installed HPUX 11.00.  I finally got gcc 
built using the following procedure:

1) Install make 3.79.1
2) Install bison 1.28
3) Install flex 2.5.4a
4) Install binutils 2.9.1
5) Bootstrap gcc 2.95.2

Despite numerous warning during the compilation, it succeeded.  However, 
when I try to compile even a pretty basic application, I get warnings 
similar to the following:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In file included from /usr/include/pwd.h:99,
                  from

/opt/gnu/lib/gcc-lib/hppa1.1-hp-hpux11.00/2.95.2/include/stdio.h:30: 
warning: this is the location of the previous definition
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I haven't been able to find any information on this error.  However, in the 
process of looking, I noticed several messages in the archives stating that 
gcc 2.95.X will not work on HPUX 11.00.

What I would like to know is this: what is the latest gcc (and binutils) 
that compiles and runs on HPUX 11.00 without any major problems?  Also, is 
there anything that I need to change in my procedure for building and 
installing gcc?

Thanks,

Eric

GCC 2.95.2 doesn't support HP-UX 11.  This is just one of the errors
you'll encounter.  Get a development snapshot.  But note that you may
still encounter problems, as the PA port has been somewhat unstable in
the past few months.  It's stabilizing for the upcoming release, but
it may not be ready yet.

I was hoping to find someone who could recommend a specific release or 
development snapshot that is known to bootstrap on HPUX 11.00 and run well.

I tried the binutils snapshot from January 23, 2001 and it compiles 
fine.  I tried to bootstrap the January 22, 2001 gcc, but it fails with a 
Segmentation Fault when trying to run xgcc.

If you have any further suggestions/recommendations, it would be appreciated.

Thanks,

Eric

I think this problem does not have anything to do with GCC not working on
HPUX
Actually, GCC provides some corrected header files like varargs.h etc. Find
the directory and include it While giving the gcc build command using the
"-I" switch as the first switch.

Tell me if this works.

Hello Puneet,

Since I had tossed the 2.95.2 build, I had to recompile.  This time I used 
the latest release (2.95.1).  I watched the compilation process more 
carefully than last time and noticed that the same warning messages occur 
during the bootstrap of the compiler.  So it would seem to me that this 
problem is more likely the result of a problem in the HP-UX source instead 
of my build environment.

If you are curious, this is the command I used to build bootstrap the compiler:

make CFLAGS='-O' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 
-fno-implicit-templates' bootstrap

I got this out of the gcc-2.95.2/install/BUILD file.

Thanks,

Eric
