rtmpdump build problem on Mac OS X using GnuTLS

[xanadu6291]

Hello,

I'm now trying to build rtmpdump under Mac OS X 10.11.1 El Capitan / Xcode 7.1.1 but yet not succeeded.

I'm trying to use GnuTLS for crypto and I'm now thinking this might be succeeded.

But in making rtmpdump, I get "ld: library not found for -lgnutls" error when executing "gcc -Wall -o rtmpdump rtmpdump.o -Llibrtmp -lrtmp -lgnutls -lhogweed -lnettle -lgmp -lz" portion.

My make command and log is as follows:

$ export TARGET ="/Users/roushi/Desktop/RTMPDump_Test"
$ make SYS=darwin CRYPTO=GNUTLS SHARED=no INC=-I${TARGET}/include

gcc -Wall  -I/Users/roushi/Desktop/RTMPDump_Test/include -DRTMPDUMP_VERSION=\"v2.4\" -DUSE_GNUTLS  -O2    -c -o rtmp.o rtmp.c
gcc -Wall  -I/Users/roushi/Desktop/RTMPDump_Test/include -DRTMPDUMP_VERSION=\"v2.4\" -DUSE_GNUTLS  -O2    -c -o log.o log.c

ld: library not found for -lgnutls
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [rtmpdump] Error 1

I have to pass

INC=-I${TARGET}/include

to let rtmpdump to find out 'gnutls/gnutls.h'

I'd like to use GnuTLS because OS X no longer provide header file of OpenSSL.

Please help me!!
