A search reveals that there are 29 math.h files on my system. Of those, these don't clearly include isinf:
/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk/usr/include/c++/4.2.1/tr1 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.0.sdk/usr/include/c++ /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.1.sdk/usr/include/c++/4.2.1/tr1/4.2.1/tr1 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.2.sdk/usr/include/c++/4.2.1/tr1 /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/usr/include/c++/4.2.1/tr1 /Developer/SDKs/MacOSX10.6.sdk/usr/include/c++/4.2.1/tr1 /Developer/SDKs/MacOSX10.6.sdk/usr/include/wx-2.8/wx /usr/include/c++/4.2.1/tr1 /usr/include/wx-2.8/wx So I tried: echo $PATH /usr/local/boost:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin Nothing obvious there. My project's header search paths include: /usr/local/include but the only thing under there is Boost, and it doesn't have a math.h. No idea at this point. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
