schroedinger undefined symbols for architecture x86_64

[cheeyeo]

Hi

I installed schroedinger using brew successfully but when I try to link it to ffmpeg 1.0 i get the following errors:

Undefined symbols for architecture x86_64:
"__schro_decode_prediction_only", referenced from:
_schro_init in libschroedinger-1.0.a(libschroedinger_1.0_la-schro.o)
"__schro_telemetry", referenced from:
_schro_init in libschroedinger-1.0.a(libschroedinger_1.0_la-schro.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Is this a fault within schroedinger or ffmpeg? I have all the paths setup correctly using pkg-config etc. The build is on OS X 10.7 Lion

any suggestions will be of great help - thanks!

Have a look at this and try to follow it: https://github.com/mxcl/homebrew/wiki/Troubleshooting
We need some more info from it. I just modified my ffmpeg formula to enable libschroedinger on ML 10.8.2, and it built without error. I can also build it on Lion with XCode-4.5.

I had the same problem compiling schroedinger on OSX with a static build into ffmpeg. For some reasons the ld of OSX does not handle external ints correctly. In file schroedinger/schrodecoder.c around line 75 just initialize the ints:

int _schro_decode_prediction_only = 0;
int _schro_telemetry = 0;

Then rebuild schroedinger and You will be fine.

By the way, there is a similar problem with gnutls and ffmpeg as well. Somewhere in verify_tofu.c, same issue.
