Hey trying to compile one C-file in MatLab, but I got this error and I'm trying to make sense of it. Any and all guidance is greatly appreciated.

>> mex BDS_unpack_mex5.c
xcrun: error: SDK "macosx10.7" cannot be located
clang: warning: no such sysroot directory: '-mmacosx-version-min=10.7'
BDS_unpack_mex5.c:17:10: fatal error: 'math.h' file not found
#include <math.h>
     ^
1 error generated.

mex: compile of ' "BDS_unpack_mex5.c"' failed.

Error using mex (line 206)
Unable to complete successfully.

  • have you setup your `mex` compiler? try `>> mex -setup` – Shai Nov 10 '13 at 09:03

    Hey Shai, thanks for the suggestion, strangely enough I believe it had to do with the OSX version set within the external compiler section of MatLab. Once I changed all of the values to 10.8 that originally read 10.7 and downloaded Xcode, everything worked beautifully. – Pierson Sargent Nov 11 '13 at 04:05
  • @PiersonSargent where did you change the values of 10.7 to 10.8? Because I am using 10.9, I may have the same problem emerging... – hhh Nov 14 '13 at 15:58

    I'd have to search around for it, it's a mexopts (mex options) file that exists within MatLab's files. Try seeing if you can't run a search for that. – Pierson Sargent Nov 21 '13 at 14:13

In order to solve this compiling here or generally as in the question, I understand this so that 

$ sed -ie 's@10.7@10.9@g' /Applications/MATLAB_R2013b.app/bin/mexopts.sh

where check your Sed flavour before running this. According to the comment you need compile Xcode again. Waiting for the upgrade...

The problem existed within the version of OSX that MatLab thought I had given that the new OSX version came out (Mavericks) and I chose to install the update. I ended up finding the file that had mex options in it, changed the OSX values to read the current version of OSX, I downloaded the current version of Xcode and voila everything functioned and I could run my 

mex BDS_unpack_mex5.c

Which allowed me to compile the mex file, use the function within and have a beautiful day =D
