WINDOWS / VISUAL STUDIO BUILD INSTRUCTIONS
|
|
==========================================
|
|
|
|
[For Linux/Unix/OSX/... instructions see README.cmake]
|
|
|
|
|
|
Directory Structure
|
|
===================
|
|
|
|
On Windows, assumptions on the directory structure are made to automate
|
|
the discovery of dependencies.
|
|
This recommended directory structure is described below:
|
|
|
|
${MSVC_3RDPARTY_ROOT} /
|
|
3rdParty / ( includes plib, fltk, zlib, libpng,
|
|
libjpeg, libtiff, freetype, libsvn,
|
|
gdal, ... )
|
|
bin /
|
|
include /
|
|
lib /
|
|
3rdParty.x64 / ( 64 bit version )
|
|
...
|
|
boost_1_44_0 /
|
|
boost /
|
|
install /
|
|
msvc100 / ( for VS2010 32 bits, or msvc90,
|
|
msvc90-64 or msvc100-64 for VS2008 32,
|
|
VS2008 64 and VS2010 64 )
|
|
OpenSceneGraph / ( OSG CMake install )
|
|
bin /
|
|
include /
|
|
lib /
|
|
SimGear /
|
|
include /
|
|
lib /
|
|
|
|
If you do not use the recommended structure you will need to enter paths
|
|
by hand. Source and build directories can be located anywhere.
|
|
|
|
|
|
Running CMake GUI
|
|
=================
|
|
|
|
The suggested inputs to cmake are :
|
|
MSVC_3RDPARTY_ROOT : location of the above directory structure
|
|
CMAKE_INSTALL_PREFIX : ${MSVC_3RDPARTY_ROOT}/install/msvc100/FlightGear
|
|
(or any variation for the compiler version described above)
|
|
|
|
1. Set up a work directory as described above.
|
|
|
|
2. Open the CMake gui.
|
|
|
|
3. Set "Where is the source code" to wherever you put the FlightGear
|
|
sources (from the released tarball or the git repository).
|
|
|
|
4. Set "Where to build the binaries" to an empty directory.
|
|
|
|
5. Press the "Configure" button. The first time that the project is
|
|
configured, CMake will bring up a window asking which compiler you wish
|
|
to use. Normally just accept Cmakes suggestion, and press Finish. CMake
|
|
will now do a check on your system and will produce a preliminary build
|
|
configuration.
|
|
|
|
6. CMake adds new configuration variables in red. Some have a value ending
|
|
with -NOTFOUND. These variables should receive your attention. Some
|
|
errors will prevent FlightGear to build and others will simply
|
|
invalidate some options without provoking build errors. First check the
|
|
MSVC_3RDPARTY_ROOT variable. If it is not set, chances are that there
|
|
will be a lot of -NOTFOUND errors. Instead of trying to fix every error
|
|
individually, set that variable and press the "Configure" button again.
|
|
|
|
7. Also check the lines with a checkbox. These are build options and may
|
|
impact the feature set of the built program.
|
|
|
|
8. Change the CMAKE_INSTALL_PREFIX to
|
|
${MSVC_3RDPARTY_ROOT}/install/msvc100/FlightGear because
|
|
C:\Program Files is likely unwritable to ordinary Windows users and
|
|
will integrate better with the above directory structure (this is
|
|
mandatory for SimGear if you don't want to solve errors by hand).
|
|
|
|
10. Repeat the process until the "Generate" button is enabled.
|
|
|
|
11. Press the "Generate" button.
|
|
|
|
12. Start Visual Studio 2010 and load the FlightGear solution
|
|
(FlightGear.sln) located in "Where to build the binaries" (point 4.)
|
|
|
|
13. Choose the "Release" build in the VS2010 "Generation" toolbar
|
|
|
|
14. Generate the solution.
|
|
|
|
15. If there are build errors, return to CMake, clear remaining errors,
|
|
"Configure" and "Generate"
|
|
|
|
16. When Visual Studio is able to build everything without errors, build
|
|
the INSTALL project to put the product files in ${CMAKE_INSTALL_PREFIX}
|
|
|
|
17. Enjoy!
|

Rebuilding Updated Sources
|
|
==========================
|
|
|
|
When updating the sources from Git, it is usually unnecessary to restart
|
|
CMake as the solution is able to reconfigure itself when CMake files are
|
|
changed. Simply rebuild the solution from Visual Studio and accept the
|
|
reload of updated projects. It also possible to edit CMakeList.txt files
|
|
directly in Visual Studio as they also appear in the solution, and projects
|
|
will be reconfigured on the next generation. To change build options or
|
|
directory path, it is mandatory to use the CMake Gui. In case of problems,
|
|
locate the CMakeCache.txt in "Where to build the binaries" directory and
|
|
delete it to reconfigure from scratch or use the menu item
|
|
File->Delete Cache.
