Description Josh Tolbert 2003-02-21 03:00:26 UTC 
	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

    switch(OS)
How-To-Repeat: 	On an i386 SMP machine:
	cd /usr/ports/math/atlas
	make
	answer yes when asked to enable multithreaded support.
	Wait for build to error out with unknown linker flag -lpthread.
