How to down and compile GIMP

1. Make sure you have the latest version of automake, autoconf, gettex, indent, and libtool.

• Go to http://www.gnu.org to get the latest versions
• To compile and install, see the example below for autoconf
 
gunzip autoconf-2.13.tar.gz
tar -xvf autoconf-2.13.tar
cd autoconf-2.13
./configure --prefix=/usr/local
make
make install

2. Make sure you have the latest version of glib and gtk

• Go to http://www.gtk.org to get the latest versions
• To compile and install

 
gunzip glib-1.2.8.tar.gz
tar -xvf glib-1.2.8.tar
cd glib-1.2.8/
./configure -prefix=/usr/local
make
make install

gunzip gtk+-1.2.8.tar.gz
tar -xvf gtk+-1.2.8.tar
cd gtk+-1.2.8/
./configure -prefix=/usr/local
make
make install

• Set CVS root to point at cvs.gnome.org:/cvs/gnome
• Check out the HOLLYWOOD branch of GIMP
 
cvs checkout -t HOLLYWOOD gimp
 
• To compile and install
 
cd gimp
aclocal
automake
autoconf
./configure -prefix=/usr/local
make
make install

To get pressure sensitivity working you will have to make the following changes to GTK
