LMDB JNI binaries for JDK 1.6

[Raju Mishra]

Hi ,

I am using java wrapper of LMDB but I would like it to work with JDK 1.6 as we don't want to upgrade our production environment to Java 7 or 8.

I got binaries of  LMDB java wrapper compiled with JDK 1.7 and 1.8 but could not get it compiled with JDK 1.6 .

Does it even work with JDK 1.6 ? If yes then please help me with the location where I can download from ?

Any help will be highly appreciated ? Please let me know if any of you tried building source code locally with JDK 1.6 and succeeded  ?

Hi Raju

Java 6 end of life was more than 2 years ago and Java 7 end of life was April this year.

I understand the trouble of upgrading a production environment but lmdbjni will never support anything later than Java 7.

I suggest you try convince your organization to upgrade to Java 8.

Cheers,

Thanks for the response.

We upgraded to JDK 1.8 and got following problem. Libraries that I downloaded from net seems are compiled with "GLIBC2.14" but our linux boxes have GLIBC 2.5.

Can you please point out if any pre-compiled version (0.4.2) already available on internet that works with GLIBC 2.5. Otherwise I will need to build with source code.

Could not load library. Reasons: [no lmdbjni64-0.4.2 in java.library.path, no lmdbjni-0.4.2 in java.library.path, no lmdbjni in java.library.path, /tmp/liblmdbjni-64-0-7927722024898199024.4: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /tmp/liblmdbjni-64-0-7927722024898199024.4)]
