This happened 2020-06-22 and obviously "make" finished without errors back then. Today 2020-10-01 I get errors in "make":

The json problem can be overcome by changing the configure line to:

./configure CC=c99 --prefix=/usr/local/gpgme-1.13.1 --with-libgpg-error-prefix=/usr/local/libgpg-error-1.38 --with-libassuan-prefix=/usr/local/libassuan-2.5.3

but then the compilation breaks at:

g++: error: unrecognized command line option '-Wsuggest-override'
make[3]: *** [exception.lo] Error 1

Incidentally, exactly the same build error occurs for gpgme-1.14.0 but built with libgpg-error-1.39. I have gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39) on my system.

Thinking that maybe the gcc version is too old I tried using instead CentOS gcc7 development environment (GCC) 7.3.1 20180303 (Red Hat 7.3.1-5) (which doesn't come out of the box). This was an educated guess as c99 is only partially supported in gcc-4.8.5. I have now successfully built:
libgpg-error-1.39
libassuan-2.5.3
gpgme-1.14.0
using gcc 7.3.1. All make check tests have passed.

Perhaps the only relevant observation is that apparently gcc 4.8.5 is too old to handle the latest sources. If this doesn't help anyone there is no point in keeping this bug report open or even publicly available.

Thanks for the report. Indeed, the convenient C99 feature of variable definition in a for statement does only work in recent gcc versions and thus it should not be used in GnuPG related code. (https://gnupg.org/faq/HACKING.html was out of sync with the version in gnupg's master repo which falsely stated that it is an allowed features.)

Thanks for the detailed report; it was easy to fix.
