You dont have to convert C into C++, C++ compiler can compile C/C++ code.
If you check rAthena‘s source code you will see that most of the code is „C“.

But I am not able to make this code compatible with rathena current.

[Normynator]

What do you do? Error logs? Something?
Just saying that something is NOT working won‘t help.

[Hidan]

ok follows all the errors

Thats probably because the diff does not work with this rA rev. Thats not because of C/C++ thats because the diff is too old.

Any C Code can use also on C++ but some functions or variables changed and this is the problem.
