Linkage errors and two insubordinate compilers

[.::SCHiM::.]

GOOD GOD I'm so FUCKING ANGRY right now \rage

I need a cryptographic library for a program of mine, so I download crypto++ it says on the project page that's compatible with all versions of VC++ from 6.0 and up.

I first tried to build the f*ck*ng thing with VC++ 2010. No luck there, the project upgrader spits out it's little report with something about a platform not being supported. I'd be lying if I said that I had expected the thing to work, since such things never work for me. I decided it'd be best to build the library with VC++ 6.0 and later import it in VC++ 2010.

This was 3 hours ago.

So I started fixing errors and faulty definitions that are common in multi platform sourcecodes (crypto++ is apparently 'compatible' with linux, mac and windows all in 1 big file!). After about 60 -/+ minutes I finally got the f*c*er to compile and link at the same time! A great victory indeed!
I ran the benchmark and the test application and all was well. I thought I was almost done so I sighed in relief because I thought that I had avoided one of those (this) incompatibility nightmares.

The last test was ran not 2 hours ago.

I made a quick and dirty test application (still in VC++6.0) with the functions and imports I needed, I tested it and it worked. Glad that everything was proceeding so smoothly I dropped all includes in my vc2010/includes dir and the library in the /lib dir. I copied the test file into my main project and hit compile. And what do think happens? That little sh*t of a compiler has the nerve to complain about conflicting typedefs! The ones I spent an hour on fixing!!!!! I was furious. I felt the urge to take a hammer to my compiler and settle this dispute real close like...

However, of course, I didn't. Since I know that it wouldn't solve anything. So I set to fixing the fixed definitions and typedefs with renewed gusto. Then after 45 minutes or so I got them working again.

As if the two compilers weren't enough for me link.exe had to complain as well. This is where I got stuck, I searched, I experimented and tried everything. But unlike compiling errors which are usually just a bunch of incompatible keywords, linkage errors are a real nightmare. These are the ones I still can't fix:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Luckily I now have a new idea! I'm going to create a dll file that exports the functions I need in VC++ 6.0, and then link to those dynamicly in VC++ 2010!
I'll post the outcome later

Similar stories anyone?

Already defined -> one of the .h files doesnt have a
#ifndef
#define
...
#endif

block or
#pragma once



the unresolved ones -> a .lib ain't included or VC decided that those had to be renamed.

I've abandoned this library and taken another one. Anyway I think it had to do with the different versions of the runtime VC6.0 and 2010 use...
