Build error on Mac OS X: "-Wno-deprecated" is valid for C++/Java/ObjC++ but not for C

[calder]

Compiling on Mac OS 10.8.5 following the Mac build instructions yields this:

gcc -I/usr/local/include -I/usr/local/Cellar/readline/6.2.4/include  -DHAVE_CONFIG_H -Wall -Wextra -Werror -Wno-deprecated -fno-strict-aliasing -fno-omit-frame-pointer -ggdb -I. -I. -c main.c -o main.o
cc1: warnings being treated as errors
cc1: warning: command line option "-Wno-deprecated" is valid for C++/Java/ObjC++ but not for C
make: *** [main.o] Error 1

It's fixable by removing "-Werror" from Makefile.in:7, but I'm not sure if that's something you want to do.

I know about this problem, but I don't know any good workarounds. I want to keep -Werror, so I put -Wno-deprecated. Deprecated functions are in libopenssl and I think it is ok to use them. They are not marked as deprecated on linux. Probably newer version of gcc will compile it. If not you can remove -Wno-deprecated and -Werror and it should be fine.

Ok, thanks!
