7.6 uses a more complete Python, so building the python executable takes some
more effort. I tried to create 8ea shell script to automate this, but it isn't
yet foolproof.
The important parts are in the following two functions:
#
# build Python required to load system tables
# 64bit if machine supports it
# add required modules like zlib and expat to executable (patchPythonSetup
#
function buildForDistrib {
# build additional libraries
quickBuild $expatBuild $expatArchive
quickBuild $zlibBuild $zlibArchive
# remove shared objects to force static linking
find $expatBuild $zlibBuild -name "*.so" -print | xargs rm 2>/dev/null
# build python
unpack $pythonBuild $pythonArchive
(
cd $pythonBuild
if [ ! -r Makefile ]
then
execute ./configure
fi
patchPythonSetup
execute make Makefile
execute make python
)
}
#
# uncomment required modules from Setup
# to include them in the executable
# instead of having them as loadable extensions
# add path for expat and zlib
# add module _random
#
function patchPythonSetup {
zlibInclude=$buildRoot/$zlibBuild
zlibLib=$buildRoot/$zlibBuild
expatInclude=$buildRoot/$expatBuild/lib
expatLib=$buildRoot/$expatBuild/.libs
# TODO: detect directories for header and libs using find and dirname
if [ ! -r $tmpDir/Setup.org ]
then
execute cp Modules/Setup $tmpDir/Setup.org
fi
cat > $tmpDir/Setup.sed <<EOF

sed -f $tmpDir/Setup.sed $tmpDir/Setup.org > Modules/Setup
echo _random _randommodule.c >> Modules/Setup
}
$zlibArchive and $expatArchive point to source tarballs of the zlib and expat
projects
quickbuild: does gunzip + tar x + configure + make
pathPythonSetup: changes the file Python-2.*.*/Module/Setup so that several of
the standard modules are linked into the python executable (instead of being in
separed shared objects), this make it easier to keep the distribution lists
current.
Really import for the installation are zlib and _random, pyexpat and _socket
are also used for some of the regression tests. Everything else is there to
make the python distribution more useful, but isn't really required.
