Run C code function in Scilab

[KLUGESHERZ, CHRISTIAN (CHRISTIAN)]

Hello all, 
There is now a long time that I try to link a simple c code to scilab. 
My goal is not to create a toolbox, just a simple function written in C that I want to call with scilab. 
I use 
	- Win XP 
	- MSYS + MinGW 5.1.4 
	- scilab 5.2.2 

I tried so many thinks but it doesn't work 
Below my last actions.. 
I tried to use : 
- mingw-utils-0.3 --> The files has been copied to folder C:\msys\mingw 
- MinGW-Dynamic_link-Scilab 
   exec builder.sce seems to be OK 
   exec loader.sce 
         doesn't work --> 
 Load macros 
  warning(_'MinGW make not found.')); 
            !--error 144 

Even there is a make file in mingw 

But I don't know if it is the right way to try to integrate the 
example csum.c and csum.h that we can find in 
C:\Program Files\scilab-5.3.0-beta-1\contrib\toolbox_skeleton\src\c 

Please could anybody give me the whole process to convert
- csub.c 
- csub.h 
with builder_c.sce 
and I think also 
- sci_csub.c 
with builder_gateway_c.sce 

And then to explain how run the c function in scilab 
I hope it's the right way 

Many thanks 

Regards 

Christian
