Hello,

My name is Darren Hallman and I work for GE corporate research
and development in Schenectady, NY.  I am having some
difficulty in compiling octave version 1.1.1 on an HP
workstation.  First let me give you the standard info:

The machine is an HP745i running HPUX-9.07 unix.  The output
from -name -s -r is:

HP-UX A.09.07

I am compiling with GCC version 2.7.2 which was downloaded
9/14/96 and I believe is very new.  The output from gcc -v is:

Reading specs from
/usr/local/lib/gcc/gcc-lib/hppa1.1-hp-hpux9.07/2.7.2/specs
gcc version 2.7.2

As far as I know the compiler is working ok, I have compiled
several other things on it in the last couple of days.

When I compile octave, libcruft (the fortran stuff) compiles
fine, but I have some trouble in liboctave.  I receive the
following output from gmake when compiling CColvector.cc:

c++ -c  -I. -I../src -I.. -I../liboctave -I../src
-I/usr/local/lib/g++-include -DHAVE_CONFIG_H
-fno-implicit-templates  -O2 CColVector.cc

gmake[1]: *** [liboctave] Error 2
gmake[1]: Leaving directory

gmake: *** [all] Error 2

I really don't know anything about templates, I only have a
limited working knowledge of C++ classes and stuff.  Am I
doing something wrong here, or is the new version of gcc just
more strict about types?  The only change I have made to the
configuration is to optimize with -O2 instead of -O, but I
also tried goig back to -O and that did not xcure the problem.

Can you give me any help here??  I would appreciate it.  I am
looking forward to using octave, I have it at home on Linux
and like it.

Thanks,

Darren Hallman
