--- Comment #11 from Jon TURNEY <jon.tur...@dronecode.org.uk> 2009-10-24 10:24:29 PST --- Attached a couple of patches with an effort to do this better. As written, this falls back to explicitly defining M_PI using -D o the compiler command line if it can't make math.h define it. This probably isn't a good idea. Probably it should do nothing, but this probably breaks stuff on some targets which should include compiler.h but doesn't? Visual C projects will need updating to use _USE_MATH_DEFINES. I have assumed that the precision of the value of M_PI is not significant, as it varies from place to place, which should be the case anyhow, as these values are only a fall-back (In reply to comment #8) > IIRC when compiling with gcc -ansi, M_PI isn't defined. > > In my math.h, its definition is wrapped in '#if defined __USE_BSD || defined > __USE_XOPEN' I have the same. I believe that -U__STRICT_ANSI__ is the way to access these definitions if you want to use -ansi, but this may be incorrect. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ Come build with us!
