Building mono from source
We use a custom version of mono that has a number of patches applied relative to the official, "upstream" mono releases. We have forks of the various git repos involved, and a branch named
develop in each of these. This branch is based on an official upstream release with additional commits for each of our patches.
On Ubuntu or Debian Linux
$ sudo apt-get install gnulib mono-devel mono-mcs libgif-dev libjpeg-dev libtiff4-dev libexif-dev git quilt
And of course to build the package you'll also need:
$ sudo apt-get install devscripts cdbs
$ sudo port install bison mono giflib git
port is the MacPorts package management command. For further information, see Build FieldWorks for Mac.
Check out sources
You'll need clones of a number of git repositories. The recommended directory layout is to have a single parent directory called
mono-sil with the clones as subdirectories:
The directory and clones can be created using the following commands:
mkdir mono-sil cd mono-sil for R in gtk-sharp libgdiplus mono mono-basic mono-calgary; do git clone email@example.com:sillsdev/$R.git done
mono repository is fairly large, so this will take a while, especially on slower internet connections.
Build and install
Building mono is done with the
BuildOptMono.sh script in
mono-calgary. Ensure you are in the
mono-sil directory, and then run:
This uses the
sudo command internally (to gain permission to install to
/opt/mono-sil) and so will ask for your password at various points.
If there are build problems it may help to "clean" the
(cd mono && git clean -dxf)
Note that the Linux binfmt system that allows you to execute interpreted programs without specifying the interpreter on the command line (eg by typing just
application.exe) will still use
/usr/bin/mono unless you reconfigure it.
Some environment variables need to be set in order for the build of
libgdiplus to find the MacPorts libraries it needs. Unfortunately, when these variables are set the builds of the other repos fail. The solution is to build in two stages, each time restricting the build to a subset of the repos. This is done by passing the name the repo(s) to the build script. You should have some variables set permanently in
~/.profile, but others are set temporarily just for building
libgdiplus. The complete sequence of commands is as follows:
export CPATH=/opt/local/include export LIBRARY_PATH=/opt/local/lib mono-calgary/BuildOptMono.sh libgdiplus unset CPATH unset LIBRARY_PATH mono-calgary/BuildOptMono.sh gtk-sharp mono mono-basic
mono-basic aren't needed for some Mac programs (eg WeSay) and so can optionally be omitted from the list of repos in the second step above.
Updating is done by pulling the latest changes in each repo and rebuilding. From the
for R in gtk-sharp libgdiplus mono mono-basic mono-calgary; do (cd $R && git pull) done mono-calgary/BuildOptMono.sh
