inchi librarie on 64

Dear ChemAxon team,

i have built a simple web application that is working on my workstation (Linux 32)

Now I wanted to deploy it internally on our web servers (Linux 64)

When I am calling the mthods I get the following error

Caused by: java.lang.UnsatisfiedLinkError: ${JBOSS_HOME}/.chemaxon/lib/inchi-1_2/libinchi.so: ${JBOSS_HOME}.chemaxon/lib/inchi-1_2/libinchi.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

I have aded in the LIBRARY_PATH ${JBOSS_HOME}/.chemaxon/lib

But I still get the error. This chemaxon that created the ${JBOSS_HOME}/.chemaxon/lib with the stuff inside.

How can I know where comes the problem? How can I check that libinchi.so is 32 or 64 ?

Thank a lot.

I have found how to detect if the library was 32 or 64

on my computer

flefevre@tx132: inchi-1_2 $ file libinchi.so
libinchi.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped

on the server

[flefevre@www3 lib]$ file inchi-1_2/libinchi.so
inchi-1_2/libinchi.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), stripped

How can I tell Chemaxon automatic procedure to generate a 64 version?

Can I download it some where? Or do I need to change my java program?

Thank again

As this is not a question about Instant JChem I have moved to topic to the JChem forum where your question should get answered.

Hi,

For faster download we pack the inchi native libraries into jars.

On linux the 32 bit version creates the

{HOME}/.chemaxon/lib/inchi-{version}/libinchi.so

the 64 bit version creates the

{HOME}/.chemaxon/lib/inchi-{version}/libinchi64.so

right after You use inchi and java downloads the file. So you can get the 64 bit version of the library the fastest way if You open any of our applet examples (or if installed the application) draw something and in Edit/Source view the inchi of the molecule in a browser using 64 bit java plugin.

But if You use it the recommended way - from the ChemAxon inchi import, export classes - it will handle these classes, jars, etc automatically.

Best Regards,

Peter

 

OK,

I have downloaded the application and installed it back in a linux 64 machine.

I have made the operation you proposed me and be able to generate the .chemaxon/lib/inchi-1_2r/libinchi64.so

Then I went back to my web server.

And I made a symbolic link between .chemaxon/lib/inchi-1_2/libinchi.so --> .chemaxon/lib/inchi-1_2r/libinchi64.so

Because the application looks everytime to the inchi-1_2/libinchi.so

What is the differences between inchi-1_2r/ and inchi-1_2 ?

It works.

Thank a lot

Hi,

I'm glad it works.

The difference is that as we integrated the different inchi versions, we have given them similar names inchi-1_0, inchi-1_1, and  inchi-1_2, and after a bug we have had to make a revised version of the last, it is inchi-1_2r. The Inchi class handles these so any version  of Marvin uses the natives made for that version, even if You use different version simultaneously.

What version of Marvin does Your web server use? I recommend to use a new version of Marvin using 1_2r inchi because the old one had some problems with multiple threads, and a minor memory leak.

Best Regards,

Peter

I use the last one Marvin using 1_2r inchi thanks to the symbolic link

Have a good day.
