compiling AI for current (release version) spring

[hoijui]

hello
i managed to compile AI\Global\TestGlobalAI from the 0.75b2 source which is available at the download page, i did not use the svn source.
i did so with the microsoft platform sdk and visual studio express C++ 2005.
(i am a java developer -> not fond of/not used to the includes and libraries problems stuff of C and C++)
when i try to use/test this (successfull) build of the AI with my current spring installation i use to play online, it gives me an "incorrect GlobalAI dll version" error when it tries to load the AI. and it is spring version 0.75b2.
i though this source is meant to compile things for the current release version of the game, isn't it? am i doing something wrong?
thanks

VS builds are not binary-compatible
with Spring, you have to compile the
.dll with mingw (or build Spring itself
with VS as well).

thanks

(... why does everyone bother using VS at all then? :-/ )

If they are developing the product, but someone else is taking care of the official release builds, they could use VS to build everything locally, and then the changes should still work the same when built by g++.

Because VS IDE rules

thanks for the replies.
hmm...
so its mainly because you like VS.
well.. ok :D
from my experience, such IDEs mainly help with special things, like GUI editors and such. For AIs, i can't see any pro using them...
so for anyone not used to any C++ IDE, it does not really matter, and something using mingw is easier -> more.. straight forward somehow, right?

Edit: problem solved (was my stupidity)

intro (can possibly be skipped when reading):
i tried to setup mingw in windows, and compile the TestGlobalAI. i got a lot of compile errors.
so i switched to linux. there it was really easy (the mingw setup and the compiling). i managed to compile and use that AI successfully.
i then tried to forward something to Java with JNI.
after some tries, i succeeded; partly.

problem:
i have a short method forwarding something from C++ to Java by JNI.
when i compile the AI as exe, calling my JNI-Test-Method from the main method, and run it in windows, it works perfectly.
when i call the same method from the AI's constructor, spring crashes.
there is a JNI method that tries to create the JVM. if successful, it should return 0, but in this case it returns -1, which stands for "unknown error".
i had the same error with the exe as well in the beginning. the problem there was, that i didn't have the dirs with necessary dll's in the PATH environment variable.
i added them through the windows System utility, and then the exe worked fine.
they now should be used in all applications -> also in spring.
could it be that spring cant find the java dll's?
do you have any other ideas?

as i am a Java dev, i don't know how to debug .. this.
if you can give me some short tips/hints/ideas
-> thanks.
