Hi there,

I’m using the Matlab coder to generate C-Code, which is used in two visual studio projects (project_a and project_b). For each project I have a matlab function (fun_a(), fun_b()), which is translated to C-Code by the matlab coder in a separated coder project.

I get a bunch of c-functions in each project, including for example

fun_a_emxutil.h, fun_a_emxutil.c
sum.h, sum.c

and

fun_b_emxutil.h, fun_b_emxutil.c
sum.h, sum.c

I build static libraries of project_a and project_b in visual studio, including the auto generated code and some interfacing.

If build and run the projects independently of each other they are working fine, but if I want to use both libraries in a new application project_c, which links the two static libs, I'm getting linker error LNK2005 : "double sum" (?a@@3HA) already defined in project_a.obj

I understand why this is happening, since the symbol sum is defined in fun_a_emxutil.h as well as in fun_b_emxutil.h with the same name. So my question is, is there any workaround or any possibility to, for example, automatically add a prefix to the generated functions during code generation?

Thanks in advance

Christian
