Workaround

$ sudo port install jshon
$ vim /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_textproc_jshon/jshon/work/jshon-20120801/Makefile

Remove -Werror from CFLAGS += -std=c99 -Wall -pedantic -Wextra -Werror and run sudo port install jshon again.

Fixed in r112672 by substituting configure.ldflags with configure.cflags in the CC variable.

[g5pw (Aljaž Srebrnič)]

Hmm... apparently the compilation fails with gcc4.2 with a warning that gets converted into an error:

/usr/bin/gcc-4.2 -arch x86_64 -Os -std=c99 -Wall -pedantic -Wextra -Werror    -c -o jshon.o jshon.c
cc1: warnings being treated as errors
jshon.c: In function ‘read_stream’:
jshon.c:350: warning: format ‘%zd’ expects type ‘signed size_t’, but argument 3 has type ‘off_t’
jshon.c:358: warning: format ‘%zd’ expects type ‘signed size_t’, but argument 3 has type ‘off_t’
make: *** [jshon.o] Error 1

Of course, we can always blacklist gcc4.2 but I prefer to get rid of the -Werror argument.

Ran into this error today too. I also prefer getting rid of the -Werror flag.
