My own compiler options

SDL Development
1

Hi!

If I want to experiment with my own compiler optimization options for
SDL-1.2.6, where can I put them in the SDL-1.2.6 source distrib file tree? I
want to recompile SDL with some new optimization settings as an experiment to
see if it has any effect on performance.

Thanks–

Oh, one more thing : I’d be interested in any results you get from your
experiments :slight_smile:

Thanks,

One way to do this is :

CFLAGS="-O3 -march=athlon-xp" ./configure
make

Hello,

you don’t need to modify any file. Simply do:

CFLAGS="-your_custom_flags" ./configure --your_config_options
