compilation or install issue

[vladp]

do I need to compile and separately install lmdb shared library to the a test program working ?

If not, what I am doing wrong (created a simple test program called locrefdcache and setup a project using Maven with the dependency specified in README.md)

There are no install/deployment instructions, so I am improvising (and being new to java).

Thx in advance for any help

ok. problem was that my test program had env_open("/tmp/testdb" ...). and I thought it would create a new file caleld testdb. Instead it was looking for a directory named /tmp/testdb.

Other than that my setup worked. I did not need to separately build and install lmdb binary.
I need to publish the project and test program somewhere, to save folks who are not proficient in Java/maven/etc, some time
