I'm trying to compile someone else's code and there isn't a simple header file. I need to link the default lapack and blas libraries on osx, and after some searching I figured they're in the Accelerate framework, and in my make.inc I used something like

LAPACK_LIBS = -framework Accelerate

Now I read in the man page that I should include

#include <Accelerate/Accelerate.h>

Is there a way I can do it in make.inc?

Sorry if this is dumb I'm not really a programmer and I've tried my best to search...

The errors I'm getting are:

2 warnings generated.

  • The fact that `_main` is undefined makes me think that something is seriously amiss with your link command, and the issue is probably unrelated to LAPACK or BLAS. What is the full link command that generated the error? – Stephen Canon Oct 28 '13 at 22:19

The #include line would go into one or more of the source files, whichever ones uses APIs from the Accelerate framework. Are you getting compile errors? If not, then there's no need to add such an include line. If you are, then you need to add it near the top of whichever file is encountering the errors resulting from lack of those declarations.
