[Axiom-developer] gcl-2.6.8pre on MAC OSX 10.2

[Page, Bill]

Camm,

I have succeeded in compiling gcl-2.6.8pre on MAC OSX 10.2 on the
SourceForge compile farm 'ppc-osx3' server, however some patches
were necessary. This machine has Xcode installed by not Fink.

First, I checked out gcl-2.6.8pre from cvs on October 15, 2006,
created a tarball and scp'd it and the standard gnu gettext-0.15
and sed-4.1.4 tarballs to my home directory on SourceForge.

Next I compiled and installed gettext and sed with
  --prefix=/home/users/b/bi/billpage/osx
creating the ~/osx/bin and ~/osx/lib directories. These are
apparently required to satisfy the gcl build dependencies on
OSX 10.2. (Note: A Fink installation might also have provided
these in the /sw directory.)

Then I added:

  export PATH=/home/users/b/bi/billpage/osx/bin:$PATH
  export LIBRARY_PATH=/home/users/b/bi/billpage/osx/lib:$LIBRARY_PATH
  export CPPFLAGS="-no-cpp-precomp"
  cd osx

to ~/.profile so that after re-login the environment was set
appropriately.

I untarred gcl into the osx directory creating ~/osx/gcl-2.6.8pre
Then I applied the following patches (most of which have been
previously reported on the gcl email list by other people):

------------------------
ppc-osx3:~/osx billpage$ diff -Naur old/gcl* new/gcl*

This patch required so libintl is found in $LIBRARY_PATH.

------------------------

Finally I built gcl with the following commands:

  ./configure --prefix=/home/users/b/bi/billpage/osx \
     --disable-tkconfig  --disable-statsysbfd --enable-locbfd
  make
  make install

---------

The resulting gcl binary (unixport/saved_gcl) in available here:

  http://page.axiom-developer.org/gcl-2.6.8-osx10-20061017.bin

I would be very happy if anyone with a MAC OSX machine would try
this version of gcl on their systems and let me know of any
problems.

I am currently working on completing the Axiom build based on the
new build-improvements branch.

Regards,
Bill Page.
