Thread Subject:

xcode 4.4 cannot see mex.h

The build command results in mex.h file not found.
In the header search paths (debug and release, any OSX) I have the standard path:
/Applications/MATLAB_R2011b.app/extern/include/
(i also tried without the final /)
mex.h is indeed present.

I can make this go away by dragging mex.h into the project, but then I have the same problem with files included by mex.h. I also tried putting the directory in the public headers folder path.

I thought it might be the wrong SDKROOT but this variable is not present in mexopts.sh.

How to include mex.h?

Thanks,
John

Follow up from thread originator

The answer I found by trial and error was to put the path into USER_HEADER_SEARCH_PATHS. Why wasnt this obvious to me? Because there seem to be many fields which would seem plausible locations for this path.
If I click on the project for instance, I get one set of fields, and if I click on the target, another set. Why doesn't the target inherit all the project settings? Which is the correct one for the mex file path?
Second, even if we stick to either project or target, there are still many header paths:
under search paths, we first see
HEADER_SEARCH_PATHS
Under packaging, we also see
PRIVATE_HEADERS_FOLDER_PATH and PUBLIC_HEADERS_FOLDER_PATH
Probably there is a nice web page somewhere explaining how to use each of these fields, and whether/when to click the little boxes that appear beside each path entry. If someone out there knows of such page, please let me know.
