Build fails on OSX using macports

[rabimba]

I am trying the macports way. And after I am done with the following steps

sudo port install libconfig-hr sudo port install readline sudo port install lua51 sudo port install python34 sudo port install libevent export CFLAGS="-I/usr/local/include -I/opt/local/include -I/opt/local/include/lua-5.1" export LDFLAGS="-L/usr/local/lib -L/opt/local/lib -L/opt/local/lib/lua-5.1" ./configure && make

This is what I get

gcc -I. -I. -I./tgl -I/usr/local/include -I/opt/local/include -I/opt/local/include/lua-5.1 -I/usr/local/include -I/usr/include -I/usr/include -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I/usr/include -DHAVE_CONFIG_H -Wall -Werror -Wextra -Wno-missing-field-initializers -Wno-deprecated-declarations -fno-strict-aliasing -fno-omit-frame-pointer -ggdb -Wno-unused-parameter -fPIC -c -MP -MD -MF dep/main.d -MQ objs/main.o -o objs/main.o main.c main.c:932:5: error: 'builtin_snprintf_chk' will always overflow destination buffer [-Werror,-Wbuiltin-memcpy-chk-size] snprintf (serv_addr.sun_path, 108, "%s", unix_socket); ^~~~~~~~~~~~~ /usr/include/secure/_stdio.h:57:3: note: expanded from macro 'snprintf' builtin_snprintf_chk (str, len, 0, darwin_obsz(str), __VA_ARGS) ^~~~~~~~~~~~~~~ 1 error generated. make: *\ [objs/main.o] Error 1

On OSX, sun_path is 104 bytes, but on Linux, it's 108 bytes.

Same problem here with Homebrew.

Changing the sun path in line 936 in main.c from 108 to 104 works.

Same problem here and fixed by @tsagi fix.
