Thunderbird-115.5.1

Installation of Thunderbird

The building system ships several internal copies of the Python 3 modules setuptools and six.py. The shipped copies are too old to work well with Python 3.12 or later. Replace them with the symlinks to the LFS setuptools package and six-1.16.0 already installed on the system, and adapt the building system for these updated Python modules. We also need to rewrite the code based on the imp module removed in Python 3.12 and later using the importlib module:

(for i in $(find -name six.py); do
   ln -sfv /usr/lib/python3.12/site-packages/six.py $i
   [ $? = 0 ] || exit $?
 done) &&

sed '/ConfigParser/s/Safe//'                          \
    -i testing/mozbase/mozprofile/mozprofile/prefs.py &&

(for i in setuptools distutils-precedence.pth  \
          pkg_resources _distutils_hack; do
   rm -rf third_party/python/setuptools/$i     &&
   ln -sv /usr/lib/python3.12/site-packages/$i \
          third_party/python/setuptools
   [ $? = 0 ] || exit $?
 done) &&

sed 's/distutils/setuptools._&/'            \
    -i python/mozbuild/mozbuild/nodeutil.py &&

sed -e '/^import/s/imp$/importlib.util/'             \
    -e 's/imp.new_module/__import__/'                \
    -e "s/imp.load_source\(.*\)/spec =               \
        importlib.util.spec_from_file_location\1;    \
        mod = importlib.util.module_from_spec(spec); \
        spec.loader.exec_module(mod)/" -i python/mach/mach/main.py &&
sed '/import imp/d' -i netwerk/dns/prepare_tlds.py

The configuration of Thunderbird is accomplished by creating a mozconfig file containing the desired configuration options. A default mozconfig is created below. To see the entire list of available configuration options (and a brief description of each), issue ./mach configure -- --help | less. Create the file with the following command:

cat > mozconfig << "EOF"
# If you have a multicore machine, all cores will be used.

# If you have installed wireless-tools comment out this line:
ac_add_options --disable-necko-wifi

# Uncomment the following option if you have not installed PulseAudio

# recommended dependencies:

ac_add_options --with-system-nss
ac_add_options --with-system-webp

# on some machines. It is supposed to improve startup time and it shrinks

Now invoke the Python mach script to compile Thunderbird:

export MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none &&
export MOZBUILD_STATE_PATH=./mozbuild               &&
./mach configure                                    &&
./mach build

This package does not come with a test suite.

Install Thunderbird by running the following commands as the root user:

MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE=none ./mach install

Empty the environment variables which were set above:

unset MACH_BUILD_PYTHON_NATIVE_PACKAGE_SOURCE MOZBUILD_STATE_PATH

mkdir -pv /usr/share/{applications,pixmaps} &&

cat > /usr/share/applications/thunderbird.desktop << "EOF" &&
