Thanks for the bug report. I've fixed the warning under clang now.

I just got this error while running luarocks install lua-cjson in Ubuntu.

In file included from lua_cjson.c:47:0:
fpconv.h:15:20: warning: inline function ‘fpconv_init’ declared but never defined
 extern inline void fpconv_init();

This is on a fresh torch install. I'm following the install instructions here and made it fine up to the step where I had to install lua-cjson. I have anaconda in my $PATH, if that's relevant.

I'm also seeing this error.

I have the following compiler installed...

Apple LLVM version 8.0.0 (clang-800.0.38)

When I sudo luarocks install lua-cjson I get the error still showing.

env MACOSX_DEPLOYMENT_TARGET=10.8 gcc -O2 -fPIC -I/usr/local/include -c lua_cjson.c -o lua_cjson.o
