Scilab 5.2.2 with SIVP 0.5.3 under Mac OS X 10.6

[Peter von Niederhaeusern]

Hi all,

I'm trying to run the SIVP toolbox under Mac OS X with version 5.2.2 of Scilab.

I installed OpenCV 2.0.0 via MacPorts. So far no problems. I could also build
the SIVP toolbox by exec('builder.sci').

Upon loading SIVP via the Toolboxes entry, I get the following message:

---dump---
Startup execution:

addinter(libsivp_path+'/libsivp.dylib','libsivp',list_functions);

Apparently there's a function "_cvAbsDiff" missing in the dynamic library.

I did a similar install on Ubuntu (Scilab 5.2.2, SIVP 0.5.3 and OpenCV
2.0.0) and encountered no problems.

Any hints?

Merci,
