Compilation errors in windows build

[ghost]

I am getting so close to having this thing compiled on windows! I used cmake gui to generate the build for visual studio 2013. It took me a while to get all the included packages. I may even write up a howto once I'm done. However, I am now getting the followng errors:

In Update.cpp line 44

rdp->update->BeginPaint = cbBeginPaint;

The error is:

C2440: '=' : cannot convert from 'void (__cdecl *)(rdpContext *)' to 'pBeginPaint'
C:\FreeRDP-WebConnect\wsgate\Update.cpp

I'm not a C or C++ programmer (I write C# code normally) so I am at a loss for what is wrong here. Here is the cmake output if that matters:

@tmakaro Try to force this flag to the compiler "-fpermissive". If it doesn't work, tell me more about your setup. x86 or x64 and your OS version, and monday I will take care of your issue.

@c64cosmin There is no -fpermissive option in visual studio 2013 that I am aware of. Here is the compilation output. I using VS2013 on a 64bit windows 10 OS.

This is the compilation output I get:

@c64cosmin I was able to get further along by casting the variables. for example

rdp->update->BeginPaint = cbBeginPaint;

to

rdp->update->BeginPaint = (pBeginPaint)cbBeginPaint;

Not sure if that was a good thing to do or not though.

So I am down to one last error:

error LNK1143: invalid or corrupt file: no symbol for COMDAT section 0x194  C:\FreeRDP-WebConnect\wsgate\build\libehs.a(ehs.o)  wsgate

I have no Idea what that means or how to fix it :)

[ghost]

@c64cosmin I got it! Would be nice if you could confirm that the casts I did are the correct fix though :)

so the problem with the libehs.a file was that it was a residual file from me trying to install ehs previously. I think I originally installed a unix version of ehs??? I removed that file and put libehs.lib in its places and the compilation process works now.
