Subject: Build error for shared version on solaris 2.8 using gcc

Hi


Compiling octave 2.1.57 with "--enable-shared" always
failed for me on solaris 2.8 using gcc 3.4.1, bailing
out when linking liboctave due to link errors.

Building static versions worked (but I need octave-
forge, so I need the shared version).

It seems that the problem is that the stuff in "glob"
is NOT compiled with "-shared".

After adding " -shared -fPIC " to CFLAGS in
glob/Makefile, everything seems to work fine
(i.e. no more errors on make, no apparent problems
after installing).

I am not a software guy, so this solution might not
be clean (or the problem might be caused by some
other peculiarity in my setup).


Thanks, Robert


PS: the working flow was:

  ./configure \
     --prefix=/usr/local \
     --enable-shared \
     --enable-dl \
     --disable-static

   then change CFLAGS in glob/Makefile to:
   CFLAGS = -g -O2 -shared -fPIC

   gmake
   gmake install
