FWIW, I just try to create a symlink from the /lib folder in the app where I'm compiling GRASS to /usr/bin/cpp. It still won't configure. So I wonder if this too is a bogus error.

I just did a restore from a back up of previously compilable trunk source code. Same error. So it is something that has changed in my system. I do have cpp in /usr/bin and it was updated recently (24 October). I do not have a link /lib/cpp and don't have a
non-updated Mac to see if this link did exist previously.

<div class="">As far as I can tell, I do not have cpp anywhere in any of the Mac binaries I've done, although I do have a C++ compiler installed. All previous versions compiled and built without this error, and they run fine. So what was changed between 8 October

<div class="">Do you mean a change in GRASS GIS source code or your system configuration (e.g. updates)? How to decide between them is to configure the last version of GRASS GIS which worked for you. If you can configure and compile from scratch that old version
but not the new one, you can try a version in between these two, the go to beginning of this sentence (aka bisect). This way you find the change in GRASS GIS. In case both the old and the new version don't configure, the change is in your system.<br class="">
