Problem compiling 64-bit version with Linux.

[bat999]

Hi
The 32-bit version of RTMPDump always compiled for me OK.
But now I have a problem compiling RTMPDump 64-bit.

$ cat /etc/issue
Linux Mint 18 Sarah \n \l

I download the git...

git clone --depth 1 git://repo.or.cz/rtmpdump.git

And apply the patch...

$ cp Patch.diff ~/rtmpdump/Patch.diff; cd rtmpdump; patch -p0 -i Patch.diff

....
Hunk #54 succeeded at 5266 (offset 2 lines).
Hunk #55 succeeded at 5675 (offset 2 lines).
Hunk #56 succeeded at 5878 (offset 2 lines).
patching file librtmp/rtmp.h
patching file librtmp/rtmp_sys.h
patching file rtmpdump.c
patching file rtmpgw.c
patching file rtmpsrv.c
patching file rtmpsuck.c
patching file thread.c

Then make...

$ make SHARED= VERSION="v2.4\ KSV-2015-12-14"

But when I try to install it there are errors...

$ make install
make[1]: Entering directory '/home/user/rtmpdump/librtmp'
gcc -shared -Wl,-soname,librtmp.so.1  -o librtmp.so.1 rtmp.o log.o amf.o hashswf.o parseurl.o  -lssl -lcrypto -lz -lm
/usr/bin/ld: rtmp.o: relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
rtmp.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status

make[1]: Leaving directory '/home/user/rtmpdump/librtmp'
Makefile:76: recipe for target 'librtmp/librtmp.a' failed
make: *** [librtmp/librtmp.a] Error 2

It seems that I have to pass some information about "fPIC" to the compiler.
How do I do this?
