rtmpdump build problem on Mac OS X using GnuTLS

rtmpdump build problem on Mac OS X using GnuTLS

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:

Code:

$ 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

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

gcc -Wall  -o rtmpdump rtmpdump.o -Llibrtmp -lrtmp -lgnutls -lhogweed -lnettle -lgmp -lz  

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

Code:

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!!

Re: rtmpdump build problem on Mac OS X using GnuTLS

You should use XCFLAGS to pass the compiler options and XLDFLAGS to pass the linker options. Try adding the following to your make command and it may fix your problem.

Code:

XCFLAGS="-I/path/to/gnutls/headers" XLDFLAGS="-L/path/to/libgnutls.a

Re: rtmpdump build problem on Mac OS X using GnuTLS

KSV-san, Thank you for reply!

I thought that XCFLAGS and XLDFLAGS should be directory. So I tried:

Code:

export TARGET ="/Users/roushi/Desktop/RTMPDump_Test"

make SYS=darwin CRYPTO=GNUTLS SHARED= XCFLAGS=-"I${TARGET}/include" XLDFLAGS="-L/${TARGET}/lib"

Then console outputs:

Code:

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

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

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

Is this error mean I have any fault on building GnuTLS?

Re: rtmpdump build problem on Mac OS X using GnuTLS

I googled the word "_iconv", referenced from:" and found the answer. (This page is written in Japanese)

I added "-liconv" to XLDFLAGS. So make statement is:

Code:

make SYS=darwin CRYPTO=GNUTLS SHARED= XCFLAGS="-I${TARGET}/include" XLDFLAGS="-L/${TARGET}/lib -liconv"

With this addition, I have succeeded to build rtmpdump with GnuTLS finally!!

Install:

Code:

make install prefix=${TARGET} CRYPTO=GNUTLS SHARED=

Hopefully there are someone who teach me how to test rtmpdump with secure connection...

If you link gnutls dynamically, you don't need to add "-liconv".
But even in this case, you need "SHARED=" to build rtmpdump correctly.
