Building Flightgear - CentOS
Work in progress This article or section will be worked on in the upcoming hours or days. See history for the latest developments. |
Preparation
A "Minimal Install" of CentOS 8 (64 bits) is needed.
Requirements
All the commands are run in bash
as normal user (not root
). The user need sudo
access to install packages and add some repos.
The following repos need to be added and enabled:
sudo dnf config-manager --set-enabled PowerTools sudo dnf install epel-release
The following packages need to be install on the the system before starting the build of FlightGear. The packages can be install using the dnf
command:
sudo dnf install freeglut-devel.x86_64 openal-soft.x86_64 freetype-devel.x86_64 libjpeg-turbo-devel.x86_64 jasper-libs.x86_64 libxml2-devel.x86_64 libcurl-devel.x86_64 \ cairo-devel.x86_64 poppler-glib.x86_64 librsvg2-devel.x86_64 gtk2-devel.x86_64 lua-libs.x86_64 lua.x86_64 fltk.x86_64 libpng-devel.x86_64 libtiff-devel.x86_64 \ libXrandr-devel.x86_64 libXinerama-devel.x86_64 zlib-devel.x86_64 expat-devel.x86_64 boost.x86_64 openal-soft-devel.x86_64 cmake.x86_64 \ mesa-libEGL-devel.x86_64 jasper-devel.x86_64 gstreamer1-devel.x86_64 SDL2-devel.x86_64 poppler-glib-devel.x86_64 lua-devel.x86_64 fltk-devel.x86_64 boost-devel.x86_64 \ dbus-devel.x86_64 libevent-devel.x86_64 glew-devel.x86_64
The plib
package is not available for CentOS 8. The package from CentOS 7 can be used instead. After downloading the following packages:
The 2 packages can be installed manually using the following command:
sudo rpm --install plib-1.8.5-15.el7.x86_64.rpm sudo rpm --install plib-devel-1.8.5-15.el7.x86_64.rpm
Definitions
The following environment variables must be set because they will be used in shell commands:
NR_JOBS
: Number of jobs for parallel compilation. For example:NR_JOBS=$(/usr/bin/nproc)
.FGFS_PREFIX
: Prefix of the Flightgear installation. For example:FGFS_PREFIX=${HOME}/Flightgear
. All the source code must be located under the directory${FGFS_PREFIX}/src
and the installation will be done under the directory${FGFS_PREFIX}
as${FGFS_PREFIX}/bin
,${FGFS_PREFIX}/include
,${FGFS_PREFIX}/lib
,...OPENSCENEGRAPH_VERSION
: Version of OpenSceneGraph. For example:OPENSCENEGRAPH_VERSION=3.6.4
.
OpenSceneGraph
OpenSceneGraph is not available as a RPM for CentOS 8 and, for this reason, needs to be build from sources. The latest stable version of OpenSceneGraph can be downloaded from here. The downloaded file must be placed under the directory ${FGFS_PREFIX}/src
such that the full path of the file will be ${FGFS_PREFIX}/src/OpenSceneGraph-OpenSceneGraph-${OPENSCENEGRAPH_VERSION}
.
The following commands can be used to build OpenSceneGraph:
cd -- "${FGFS_PREFIX}/src/" rm -Rf -- "${FGFS_PREFIX}/src/OpenSceneGraph_build/" mkdir -- "${FGFS_PREFIX}/src/OpenSceneGraph_build/" OPENSCENEGRAPH_SRC=${FGFS_PREFIX}/src/OpenSceneGraph-OpenSceneGraph-${OPENSCENEGRAPH_VERSION} rm -Rf -- "${OPENSCENEGRAPH_SRC}/" tar axvf "${FGFS_PREFIX}/src/OpenSceneGraph-OpenSceneGraph-${OPENSCENEGRAPH_VERSION}.tar.gz" pushd -- "${FGFS_PREFIX}/src/OpenSceneGraph_build/" cmake "${OPENSCENEGRAPH_SRC}" \ -DCMAKE_BUILD_TYPE=Release \ -DBUILD_OSG_EXAMPLES:BOOL=ON \ -DOSG_USE_LOCAL_LUA_SOURCE:BOOL=OFF \ -DCMAKE_INSTALL_PREFIX="${FGFS_PREFIX}" \ -DLIB_POSTFIX=64 \ -DCMAKE_VERBOSE_MAKEFILE=TRUE make --jobs=${NR_JOBS} make -- install popd rm -Rf -- "${OPENSCENEGRAPH_SRC}/" rm -Rf -- "${FGFS_PREFIX}/src/OpenSceneGraph_build/"
Simgear
The source code of Simgear can be provided:
- as an official release that can be downloaded from here. The environment variable
SIMGEAR_VERSION
must be set to the relevant version of Simgear, for exampleSIMGEAR_VERSION=2019.1.1
and then using the following commands to extract the source code:
cd -- "${FGFS_PREFIX}/src/" SIMGEAR_SRC=${FGFS_PREFIX}/src/simgear-${SIMGEAR_VERSION} rm -Rf -- "${SIMGEAR_SRC}/" tar axvf "${FGFS_PREFIX}/src/simgear-${SIMGEAR_VERSION}.tar.bz2"
- as a clone of the Simgear Git repo by using the following commands:
cd -- "${FGFS_PREFIX}/src/" git clone https://git.code.sf.net/p/flightgear/simgear flightgear-simgear SIMGEAR_SRC=${FGFS_PREFIX}/src/flightgear-simgear
- if you have already a clone of the Simgear Git repo, the local copy can be updated using the following commands:
cd -- "${FGFS_PREFIX}/src/" SIMGEAR_SRC=${FGFS_PREFIX}/src/flightgear-simgear pushd -- "${SIMGEAR_SRC}/" git pull popd
Now that the source code of Simgear is available under the directory ${SIMGEAR_SRC}
, the build can be started using the following commands:
cd -- "${FGFS_PREFIX}/src/" rm -Rf -- "${FGFS_PREFIX}/src/sg_build/" mkdir -- "${FGFS_PREFIX}/src/sg_build/" pushd -- "${FGFS_PREFIX}/src/sg_build/" cmake "${SIMGEAR_SRC}" \ -DCMAKE_BUILD_TYPE=RelWithDebInfo \ -DCMAKE_INSTALL_PREFIX="${FGFS_PREFIX}" \ -DCMAKE_VERBOSE_MAKEFILE=TRUE make --jobs=${NR_JOBS} make -- test make -- install popd rm -Rf -- "${FGFS_PREFIX}/src/sg_build/"
Flightgear
The source code of Flightgear can be provided:
- as an official release that can be downloaded from here. The version of Simgear and Flightgear must match. The environment variable
FLIGHTGEAR_VERSION
must be set to the relevant version of Flightgear, for exampleFLIGHTGEAR_VERSION=2019.1.1
and then using the following commands to extract the source code:
cd -- "${FGFS_PREFIX}/src/" FLIGHTGEAR_SRC=${FGFS_PREFIX}/src/flightgear-${FLIGHTGEAR_VERSION} rm -Rf -- "${FLIGHTGEAR_SRC}/" tar axvf "${FGFS_PREFIX}/src/flightgear-${FLIGHTGEAR_VERSION}.tar.bz2"
- as a clone of the Flightgear Git repo by using the following commands:
cd -- "${FGFS_PREFIX}/src/" git clone https://git.code.sf.net/p/flightgear/flightgear flightgear-flightgear FLIGHTGEAR_SRC=${FGFS_PREFIX}/src/flightgear-flightgear
- if you have already a clone of the Flightgear Git repo, the local copy can be updated using the following commands:
cd -- "${FGFS_PREFIX}/src/" FLIGHTGEAR_SRC=${FGFS_PREFIX}/src/flightgear-flightgear pushd -- "${FLIGHTGEAR_SRC}/" git pull popd
Now that the source code of Flightgear is available under the directory ${FLIGHTGEAR_SRC}
, the build can be started using the following commands:
cd -- "${FGFS_PREFIX}/src/" rm -Rf -- "${FGFS_PREFIX}/src/fg_build/" mkdir -- "${FGFS_PREFIX}/src/fg_build/" pushd -- "${FGFS_PREFIX}/src/fg_build/" cmake "${FLIGHTGEAR_SRC}" \ -DCMAKE_BUILD_TYPE=RelWithDebInfo \ -DCMAKE_INSTALL_PREFIX="${FGFS_PREFIX}" \ -DCMAKE_VERBOSE_MAKEFILE=TRUE make --jobs=${NR_JOBS} make -- test make -- install popd rm -Rf -- "${FGFS_PREFIX}/src/fg_build/"
