- --disable-dependency-tracking speed up one-time builds
- --enable-link-sh decrease the number of direct dependencies
+ --disable-dependency-tracking speed up one-time builds (maybe)
+ --disable-special-linking do not use direct dependency minimizer
+ --enable-profile compile in gprof profiling instructions
Program options:
- --enable-debug include debugging symbols and code paths
- --enable-double-precision use doubles instead of floats
- --enable-profile compile in gprof profiling instructions
- --enable-clock_gettime use clock_gettime() for timing
- --enable-threads use threads for concurrency
- --enable-hotloading watch assets for automatic reloading
+ --enable-clock_gettime use a very accurate timing function
+ --enable-debug compile in assertion checks and other debug helps
+ --enable-double-precision use larger floating-point numbers
+ --enable-hotload automatically reload modified game assets
+ --enable-threads use threads for concurrency where appropriate
