[GRASS-dev] GRASS 7.4.2 won't configure on Mac

[Michael Barton]

Hi Vaclav,

Thanks for the input. I've been out of town and have not been able to look into this until today.

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 and the release of 7.4.2 that makes configure fail if cpp is not found? Where should I look?

Michael

Since it's complaining about /lib/cpp,

./configure: line 5164: /lib/cpp: No such file or directory

I would say the problem is not zlib, but missing C++ compiler (at least on my machine, /lib/cpp eventually points to /usr/bin/cpp-5), although I don't know why ./configure would catch that problem earlier since a successful report contains:

  C compiler:                 clang -O2 -Wall -pedantic -Wextra
  C++ compiler:               clang++ -std=c++14 -fexceptions

The checking phase reports only about C compiler, so the difference is perhaps there.

checking for gcc... clang
checking whether the C compiler (clang -O2 -Wall -pedantic -Wextra -s) works... yes
checking whether the C compiler (clang -O2 -Wall -pedantic -Wextra -s) is a cross-compiler... no
checking whether we are using GNU C... yes
checking whether clang accepts -g... yes
