Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Library Functions Group: 2.3.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: Martin Kamp Jensen () Assigned to: Nobody/Anonymous (nobody) Summary: Java bindings trouble Initial Comment: There are serious problems with the Java bindings. It took me quite a while to get them working in both Linux and Mac OS. In Windows 7 x64 I had no problems. I just needed openbabel_java.dll from the OpenBabelGUI package to be in java.library.path. Mac OS: I built the Java bindings using the instructions at [1] (including using Eigen2). However, it turns out that it is not sufficient to just place the resulting libopenbabel_java.so file in java.library.path. It needs to be renamed to libopenbabel_java.jnilib and the (advanced) instructions at [2] need to be followed because apparently there is some setup/compile glitch regarding where the compiled .so file will think its required library files are located. Linux: Using "ld" I could see that the glitch from above is also present in Linux. I did not find a tool similar to "install_name_tool" so instead I found out that I needed to follow the instructions in the Java README [3]. There is a typo (openbabel_java.cpp needs to be openbabel-java.cpp) and there will be complaining about a "babelconfig.h" file which I copied from the build directory created using CMake as described in [4]. In the end, the resulting libopenbabel_java.so file needs to be in java.library.path and I needed to do the LD_PRELOAD trick. To sum up, I think that there is room for improvement :) Thanks for your work so far!
