Hello,

i have a problem with a pointer and need someone to explain me how to fix it. My code is the following:

      std::vector<char> v;
      peh.rebuild(v);

The method rebuild() has the following signature:  void rebuild(std::vector< byte > &vBuffer) const
Whenever i try to call the method the way i described above, i get the following error:
d:\...\patchengine.cpp(558) : error C2664: 'PeLib::PeHeaderT<x>::rebuild' : cannot convert parameter 1 from 'std::vector<_Ty>' to 'std::vector<_Ty> &'. How do i  have to call the method so the above works?

Thank you.

Does it work if you pass std::vector<byte> to the method, instead of std::vector<char>?
I would suspect that you have some implicit casting going on, that produces std::vector<byte>.

signature:  void rebuild(std::vector< byte > &vBuffer) -> byte here

std::vector<char> v; --should be-> std::vector<byte> v;

Otherwise passing the parameter looks alright

if i put byte as a parameter it doesnt compile, i changed it to <unsigned char> and it works. i should have told you im using c++ so there is no such type as byte.

thanks.

The problem is that char is signed, and byte (which is probably just a typedef of unsigned char) is not ...
