well, i guess i am doing things a little "out-of-order" because i am building FLTK on windows using mingw/msys using a ./configure, make, make install. on the configure stage FLTK looks for pthread.h and a pthread lib. if it doesnt find them it sais THREAD SUPPORT: NO when done configuring. since i dont have visual basic or whatever it is called "), how would i build FLTK with mingw and windows native thread support? > >> For now i got pthreads-win32 >> http://sourceware.org/pthreads-win32/ and successfully >> built FLTK against it (i had to add a check for >> -lpthreadGC2 in configure.in). > > Sure, this works, but is a lot of extra work, which you don't need. > pthreads-win32 just wraps win32 native threads anyway. > >> Now i wonder: both, FLTK and my app use the pthread lib.

Just use the native threads. i hope i wont soon either ") ty, jan _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
