Compiling GNU Pascal (GPC) from Scratch
for Mac OS X Tiger
(or "The Twelve Steps to GPC Bliss")

This is a brief overview of how to get GNU Pascal to compile from scratch under Tiger.

Alternatively, you can get the binary distribution from here.

You will also want to consider installing the Mac OS X Pascal Interfaces for GNU Pascal, and the Xcode integration Kit.

Special thanks to Adriaan van Os for most of the Pre-Tiger information.


Steps-at-a-Glance

  1. Create a build directory
  2. Install bison version 2.0
  3. Install flex version 2.5.27
  4. Install sed version 4.1.4
  5. Install help2man version 1.35.1
  6. Download gcc version 3.4.3
  7. Download gpc-20050331
  8. Configure gcc/gpc
  9. Patch gcc for Mac OS X
  10. Build gcc
  11. Install gp
  12. Setup some links


STEP 1 - Create a build directory

cd
mkdir gpc-build
cd gpc-build


STEP 2 - Install bison version 2.0

curl -s -S -O http://ftp.gnu.org/gnu/bison/bison-2.0.tar.gz
tar zxf bison-2.0.tar.gz
cd bison-2.0
./configure
make
sudo make install
cd ..


STEP 3 - Install flex version 2.5.31

curl -s -S -O http://easynews.dl.sourceforge.net/sourceforge/lex/flex-2.5.27.tar.gz
tar zxf flex-2.5.27.tar.gz
cd flex-2.5.27
./configure
make
sudo make install
cd ..


STEP 4 - Install sed version 4.1.4

curl -s -S -O http://ftp.gnu.org/gnu/sed/sed-4.1.4.tar.gz
tar zxf sed-4.1.4.tar.gz
cd sed-4.1.4
./configure
make
sudo make install
cd ..


STEP 5 - Install help2man version 1.35.1

curl -s -S -O ftp://ftp.gnu.org/gnu/help2man/help2man-1.35.1.tar.gz
tar zxf help2man-1.35.1.tar.gz
cd help2man-1.35.1
./configure --enable-nls=no
make
sudo make install
cd ..


STEP 6 - Download gcc version 3.4.3

curl -s -S -O ftp://ftp.gnu.org/gnu/gcc/gcc-3.4.3/gcc-core-3.4.3.tar.bz2
bunzip2 gcc-core-3.4.3.tar.bz2
tar xf gcc-core-3.4.3.tar


STEP 7 - Download gpc-20050331

curl -s -S -O http://www.g-n-u.de/gpc/gpc-20050331.tar.bz2
bunzip2 gpc-20050331.tar.bz2
tar xf gpc-20050331.tar
mv p gcc-3.4.3/gcc


STEP 8 - Configure gcc/gpc

mkdir build
cd build
../gcc-3.4.3/configure --enable-languages=pascal,c --enable-threads=posix --prefix=/Developer/Pascal/gpc-20050331


STEP 9 - Patch gcc for Mac OS X

gcc 3.4.3 has a problem with Mac OS X 10.4, so apply the patch from here, execute the patch command, and paste in the following lines:


patch -p0 --ignore-whitespace << EOM
--- ../gcc-3.4.3/gcc/config/darwin.h.sav 2005-05-18 13:56:37.000000000 -0400

EOM


STEP 10 - Build gcc

make EXTRA_PFLAGS=--longjmp-all-nonlocal-labels STAGE1_CFLAGS='-g -DHAVE_DESIGNATED_INITIALIZERS=0' bootstrap
sudo make install
cd ..


To remake if you make any changes, use:

make EXTRA_PFLAGS=--longjmp-all-nonlocal-labels STAGE1_CFLAGS='-g -DHAVE_DESIGNATED_INITIALIZERS=0' all-gcc


STEP 11 - Install gp

gp does not handle capital letters in unit names, even on case insensitive file systems. The patch resolves that issue.


curl -s -S -O http://fjf.gnu.de/misc/gp.tar.bz2
bunzip2 gp.tar.tar.bz2
cd gp-0.60
patch -p1 --ignore-whitespace << EOM

STEP 12 - Setup some links
