Building FlightGear with osgEarth Integration

This article is a stub. You can help the wiki by expanding it.

Assumptions

• You already have working branches of SG/FG and FG, you only need to add the simperative branches as remote tracking branches
• $SG_SRC, $FG_SRC and $FG_ROOT must be clean checkouts, commit/stash any unsaved work and check out next/master first.

Building the osgEarth plugin

• clone the repository:

  git clone -v -b 2.12-OsgEarthIntegration git@gitorious.org:fg/flightgear-osgearth.git flightgear

• create a separate build directory
• configure via CMake, set -DCMAKE_INSTALL_PREFIX matching your OSG/SG/FG installation path (not needed if you installed OSG/SG system-wide)
• run "make install" (to run a parallel build, pass -j x, where is x the number of cores available/to be used)
• next, build SimGear

SimGear

Switch into your cloned SimGear repository, make sure that it is in a clean state (commit/stash any changes, switch to next)

## add a new remote alias 
git remote add simperative  git@gitorious.org:fg/simgear-osgearth.git

## fetch all branches
git fetch simperative

## check out a remote tracking branch named topics/osgearth
git checkout --track -b topics/osgearth simperative/2.12-OsgEarthIntegration

• run make -j4 install
• switch to your FG_SRC directory

FlightGear

Switch into your cloned FlightGear repository, make sure that it is in a clean state (commit/stash any changes, switch to next)

git remote add simperative  git@gitorious.org:fg/flightgear-osgearth.git
git fetch simperative 
git checkout --track -b topics/osgearth simperative/2.12-OsgEarthIntegration
