math/atlas will not build with multithreaded support enabled without changing the flag used to link against POSIX threads from -lpthread to -pthread. This issue shows up on SMP machines cause Atlas doesn't ask to build with multithreading support on single-CPU machines. The problem will occur under both 4.x and 5.x. Fix: cd /usr/ports/math/atlas make patch Apply the following patch to math/atlas/work/ATLAS/config.c make Build should finish without errors, after which you can "make install".--fTYwe0GyxuJtfE3e6eAsTPeTYNWKOZm9YRahRz8oEMDUaNQY Content-Type: text/plain; name="file.diff" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="file.diff" --- config.c Thu Feb 20 20:11:53 2003 +++ config.c.new Thu Feb 20 20:12:08 2003 @@ -1091,7 +1091,7 @@ void GetSyslib(enum OSTYPE OS, enum MACHTYPE mach, char *targ, char *LIBS) { - if (THREADS) strcpy(LIBS, "-lpthread -lm"); + if (THREADS) strcpy(LIBS, "-pthread -lm"); else strcpy(LIBS, "-lm"); switch(OS) How-To-Repeat: On an i386 SMP machine: cd /usr/ports/math/atlas make answer yes when asked to enable multithreaded support.
