| « Pre-Compile Configuration | The fs2_open on Linux Guide Optimization |
Compiling » |
Warning: If you compile a debug build, don't use the -fomit-frame-pointer and -fno-ident compiler flags, as it will make debugging impossible.
Note: This step is only for those who want the bleeding-edge source code to compile on their own. You can skip this if you intend to use a provided binary executable.
Optimizing fs2_open might have little or no effect, or improve performance greatly, I honestly have no clue.
You can specify your compiler flags with the configure script, se below.
$ ./configure CFLAGS="<your desired flags>"
If you got a i686 and want to play it safe, a good set of CFLAGS would be
$ ./configure CFLAGS="-march=i686 -O3 -pipe -fomit-frame-pointer -fno-ident" CXXFLAGS="$CFLAGS"
You should read up on CFLAGS and what they do before trying anything. I recommend you read through these links.
