KSV-san, Thank you for reply!

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

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

Then console outputs:

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

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