Understood but why didn't you just say this rather then talk about runtime performance ??? < see below > >What I want to see is for FlightGear to compile >in something under 20 minutes on my machine.

WeatherCM can be bypassed with a configure switch I believe that JSBSim and UIUC and othe FDMs can be cut out of t he build by deleteing their entries from the FDM / Makefile.am and commenting out the appropriate lines in Main / fg_init.cxx :: void fgInitFDM() and removing their link lib directives from Main / Makefile.am You also have to #ifdef out UIUC aircraft_dir entries in fg_props.cxx main.cxx and fg_init.cxx This should speed up your YASim specific build time considerably FWIW Win2k 733 PIII 256 meg Cygwin without the above tricks #! /bin/sh # bootstrap.sh -- toplevel script for a fresh FlightGear Build make clean rm config.status rm config.cache CXXFLAGS="-O2 -W -Wall -march=i686" ./configure --with-network-olk=no --with-efence=no --with-logging=yes --with -jpeg-factory=yes make nhv@SFDEV3::/src/FlightGear% time ./bootstrap.sh .............. real 19m42.347s user 17m30.419s sys 2m18.101s So it looks like < 20 minutes is a reality on somewhat 'modest' machines And Cygwin is a slow poke :-) FWIW_2 with above tricks for optimized YASIM build times ./configure (as above plus) --with-new-enviroment nhv@SFDEV3::/src/FlightGear% time ./bootstrap.sh .............. real 11m39.212s user 10m0.648s sys 1m40.002s Cheers Norman _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
