Hi Rafa, Thanks for your clarifications. I think I have a good idea of what I need to do now. I am hesitating to use Visual C because I don't want to sacrifice gigabytes of disk space just to get some C code compiled and I absolutely loath the semantics of cmd.exe and all those MS development tools. So I might adapt those CMake files to run MingW/GCC instead.
Some build notes would be helpful, though. I will let you know if I run into another problem or in the unlikely case that I figure something out which you didn't know before!

If you want compile jni bindings by yourself, I recommend you use the fixed versions (3D branch) but by now they are not oficial!. Trunk version I'm sure is not compiled against GDAL 1.6.3. Binaries from 3D branch are built against that version using Visual Studio 2008 SP1. > 2. What's in the "libjni-addo" project?

If you mix visual studio versions probably will give you crashes, because of mixing c++ runtime versions. JNI world is not as funny as Java! hehe. > 4.

Currently we are using CMake for multiplatform building. So only some basic knowledge of CMake is needed. We probably upload a BUILD_NOTES.txt to each jni project on the branch with a simple guide. Another problem that Agustin said is that I was not able to generate correctly ecw and mrsid libraries for MacOSX. ECW compiles and should work... but once you try to load a file it gives an exception and aborts the process :(. MRSID doesn't compile at all, I have the requested SDK but the build process gives some linkage problems. If you find a solution to the problem I will very pleasead to upload the changes to the 3D branch.
