Hello All I am going mad! I spent 3 days compiling this software unsuccessfully.... I am not an expert on compiling software or with libraries so maybe I miss a very obvious passage that no-one stated anywhere... Here's exactly what I have done I have osx 10.5 intel and I have installed the xcode from the cd. I downloaded the tar.gx archive for and I am trying to built rtmpdump 2.2d and I tried make posix. I got this rtmpdump-2.2d user$ make posix make[2]: Nothing to be done for `all'. gcc -Wall rtmpdump.o librtmp/librtmp.a -o rtmpdump -lssl -lcrypto -lz Undefined symbols: "_mpi_init", referenced from:

not found collect2: ld returned 1 exit status make[1]: *** [rtmpdump] Error 1 make: *** [posix] Error 2 I tried to download other version of the software (the 1.9, 1.4, 2.1, 2.2c and 2.2d), same result. Now I am working with the 2.2d. I installed the zlib 1.2.5 and the openssl-1.0.0... this one gave me a couple of problems but eventually I managed to resolve it... well, I had no more "error" stated in the end but I don't know if the installation was really ok.... I suppose so... the rtmpdump, however, give me the same message error... please I need help... I really don't know anymore what to do! I even tried other software (flvstreamer, videothief and many others, with no result) any help would be VERY appreciated thanks in advance
