Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

These are some handy switches

  • -D CMAKE_VERBOSE_MAKEFILE=TRUE : get the make-style actual commands instead of just the progress indications.
  • -D CMAKE_BUILD_TYPE="RELWITHDEBINFO" : Use some optimization

An example of command-lines for a local build:

  • OSG/cmake.txt:
cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe  -march=native -mtune=native  -mfpmath=sse -Wall"\
-D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe  -march=native -mtune=native -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" $1
  • SimGear/cmake.txt:
 cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe  -march=native -mtune=native  -mfpmath=sse -Wall"\
-D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe  -march=native -mtune=native  -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" -D JPEG_FACTORY:BOOL="ON" $1
  • FlightGear/cmake.txt:
cmake -D CMAKE_BUILD_TYPE:STRING="Release" -D CMAKE_CXX_FLAGS_RELEASE:STRING="-O3 -g -pipe  -march=native -mtune=native -mfpmath=sse -Wall"\
-D CMAKE_C_FLAGS_RELEASE:STRING="-O3 -g -pipe -march=native -mtune=native -mfpmath=sse -Wall" -D CMAKE_INSTALL_PREFIX:PATH="$HOME/FlightGear/fg.git" -D FG_DATA_DIR="/some/path/" $1


Changed the order of cmake's source path and option as suggested by man cmake. This is to prevent makeing new users of cmake confused. It also has the advantage that options like "-D CMAKE_SOME_OPTION=something" (instead of "-DCMAKE_...") do work. If you don't like that change, just undo it, thanks.
