Suppress gcc warning when using function pointers with void* argument

Let's say I have function accepting function pointer as argument.

void fun(void(*problematicFunPointer)(void*) problemFun){
...
}

Then, when I want to use this function like this:

void actualProblematicFun1(struct s_something * smt){
...
}

void actualProblematicFun2(struct s_something_else * smthels){
...
}

int main(){
    fun(&actualProblematicFun1);
    fun(&actualProblematicFun2);
}

When using -Werror, this throws compile error -Werror=incompatible-pointer-types. Is there a way to suppress warning for this particular case?

Solution 1:

Write the actual functions with proper argument type that matches the declaration.

void actualProblematicFun1(struct s_something * smt){
...
}

void actualProblematicFun2(struct s_something_else * smthels){
...
}

void actualProblematicFun1Trampoline(void *smt) {
   actualProblematicFun1(smt);
}

void actualProblematicFun2Trampoline(void *smthels) {
    actualProblematicFun2(smthels);
}


int main(){
    fun(&actualProblematicFun1Trampoline);
    fun(&actualProblematicFun2Trampoline);
}
