Fwd: groff git HEAD not building on macOS? (was: Long text in tbl won't

I meant to send this to the mailing list, but accidentally sent it only to
Axel Kielhorn <tex@axelkielhorn.de>.

I've since updated to Xcode Version 12.4 (12D4e), and still got the same
result, building from a clean git checkout of groff, and still have the
problem below.

This error:

In file included from src/libs/libgroff/curtime.cpp:20:
In file included from
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/stdlib.h:100:
./lib/math.h:38:3: error: "Please include config.h first."
 #error "Please include config.h first."

looks to me like the system c++ stdlib.h is including groff's lib/math.h,
even though the line 100 mentioned above is just

#include <math.h>

I tried the groff-1.23.0.rc1 tar ball and got these results when trying
make:

I'm using the system gcc, which of course is actually clang-1200.0.32.28:


# tkb@vidar:~/sw/src/groff/rc/groff-1.23.0.rc1
$ type gcc
gcc is /usr/bin/gcc

# tkb@vidar:~/sw/src/groff/rc/groff-1.23.0.rc1
$ gcc -v

I'm on macOS Catalina, version 10.16.7.  I never use Xcode, but I assume
that's where the system compiler comes from and it is Version 12.3 (12C33).

I'm using homebrew:

# tkb@vidar:~/sw/src/groff/rc/groff-1.23.0.rc1
$ brew --version
Homebrew 2.7.7-65-g4ae8dfe
Homebrew/homebrew-core (git revision 49270; last commit 2021-02-01)
Homebrew/homebrew-cask (git revision ba29cf; last commit 2021-02-01)


Has anybody else with macOS Catalina or BigSur tried this?

I'll try the git version again tomorrow when I've got some time.
