[Scilab-Dev] How use a custom library in a toolbox ?

[Collette Yann]

Just a stupid suggestion: do you have tested with scilab-5.1.1 and not 
scilab master ?
I had a problem with a toolbox. In this toolbox, I have a gateway and a 
source directory -> 2 libraries (2 dlls in fact)
with 5.1.1, everything compiles fine, but with scilab master, it wasn't 
able to find one of the dll.
