Native library is not initialized

Hi there,

When I try to convert a SMILES to InChI or InChI key using the REST web service (just using the demo page, locally on my computer) for stringMolExport, I get the following exception:

{

    "errorCode": 0,

    "errorMessage": "Native library is not initialized.",

    "rootCause": "chemaxon.marvin.io.MolExportException"

}

I am running tomcat on OSX 10.8. Do I need to somehow load up the InChI library somewhere? I'm just using the .war file to run the server in tomcat. I'm using the latest java 1.7 release and the latest release of web services (6.0.2).

Thanks,
Craig

P.S. The REST web services are a pleasure to use so far!

I have this working fine in Linux, so I assume it is a Mac OSX issue.

We use jni-inchi library and as far as can remember we already had some issue with its MacOS support. We are going to investigate this issue.

Sounds good. It also happens when trying to save a file to InChI format in the marvin applet, as well as in JChem SOAP webservices.

I'm wondering if upgrading to Java 7 caused this to happen? I have 3 folders in my .chemaxon/lib directory:

inchi-1.3
inchi-1_3jni
osx

The osx directory is empty.

I'm wondering if the inchi library is compatible with java 7?

Thanks,

Craig

Hi Craig,

 

I'm sorry for the late answer.

We've managed to track down the root of the issue and it turned out to be a tricky one:

In Java 7 on Mac, the extension of the native libraries have changed.

If you create a symlink or copy the libinchi.jnilib to libinchi.dylib, Inchi starts to work.

We will fix this issue in one of the upcoming release in this month.

Regards,

Peter

On OSX, libinchi is still being installed with the .jnilib extension and will fail to initialize.  Changing it to dylib makes everything work well.  I came across this solution in a two year old post, but seems like something that should be fixed by now.  Just a friendly heads up.

Thanks,

Dan
