[ncl-talk] WRAPIT error: stdio.h: No such file or directory

[Philippe Papin]

Hi Rick and Dennis,

I believe I do have XCode developer tools on my Mac.

Ultimately I figured out the error was related to how newer versions of
MacOSX (I'm running v10.15.4 Catalina) store critical headers to compile C
programs. It turns out the <stdio.h> file was in another location on my
machine, rather than in */usr/local/lib* which is where the current version
of *gcc* I'm using is located.

To fix that, this stackoverflow thread helped (in particular setting this
option below):
https://stackoverflow.com/questions/52509602/cant-compile-c-program-on-a-mac-after-upgrade-to-mojave

export
CPATH=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/

After that, WRAPIT was able to compile the fortran program properly!

(base) Philippes-MacBook-Pro:test pppapin$ WRAPIT ex.f



WRAPIT Version: 120209

COMPILING ex.f

LINKING

END WRAPIT



Hope this can be a useful guide for people who run into the same issues
trying to use WRAPIT on a Mac.

-Philippe
