Note: -lmx is required for C99 float functions such as sqrtf, in math.h
When I try the same in Xcode (with -lmx specified in Other C Flags), I
get an error:
gcc-3.3: -lmx: linker input file unused because linking not done
ld: Undefined symbols: _sqrtf
How can I persuade Xcode that sqrtf exists?
Other C Flags is used for compiling, but -lmx is a linker flag. Other
Linker Flags is used for linking. Set that and this'll work.
A more Xcode-like way to do this is to add /usr/lib/libmx.dylib to your
project: Project->Add To Project, type '/' to get a Go To dialog, go to
/usr/lib, select libmx.dylib, and then build.
Hope this helps,
Eric
