As I handle c++ objects, it's more convenient for me to use c++ files in my gateway. Thus, for the compilation in scilab, I just need a header where i summerize all my functions as follows :<br>
<br>extern "C"{<br>int func1(char *fname)<br>int func2(char *fname)<br>...<br>} "<br clear="all"><br>When those functions "func1", "func2" are linked to the c++ original code, the compilation in scilab works perfectly (builder and loader).<br>
However, when those functions are linked to the fortran original code (which means that in my gateway file, I call a fortran function with "F2C"), the compilation in scilab doesn't work and i get the following error while I'm trying to execute the loader (the builder passes) :<br>
<br>addinter(libsplspcgateway_path + filesep() + 'libsplspcgateway' + getdynlibext(), 'libsplspcgateway', list_functions);<br> !--error 236 <br>
addinter: The shared archive was not loaded: /home/.../sci_gateway/cpp//libsplspcgateway.so: undefined symbol: BAGMRES_<br><br>(where BAGMRES is the fortran function that I call with F2C in my gateway file in c++).<br><br>
As I already succeeded to use fortran functions in gateway files in c, my question is the following :<br>Is it forbidden to call a fortran file in a gateway file in c++ and must I use inevitably a gateway file in c?<br>If on contrary it's possible, where could the problem come from?<br>
<br>I hope to be clear and I thank you for your help.<br>Best regards,<br> <br>-- <br>Benoit Goepfert<br><br>
