Hello Ahmed,

I have a similar problem as yours. I have a project
written on Matlab 7 R14 sp3. I use the comtool with C++
compiler version 6.0. This project is divided into 5
subprojects, i.e., many functions grouped in 5 dlls. My
problem appears when i use two functions from different
dlls, one gives an error while the other runs ok.

did you finally find the solution to your problem?

thanks in advance.

Bego?a.
