lua 5.2, MDB 0.9.11, Debian sid i686,

[shmul]

This is probably due to a failure to create the ./temp/testdb directory. I added the -p flag and pushed an updated version. Please tell me whether it works.

[ad1862]

I think the problem in something else, because ./temp/testdb directory is successfully created, but still not work..

upd: my lmdb installation crashes with segfault after mtest`s

[shmul]

Can you please provide me environment details - what OS you are using? What lmdb version?
When you say mtest segfaults, you mean that lmdb's own tests fail?

Yes, I built, installed and tried to run lmdb tests (mtest1, 2, 3 ...)
all these tests return "segmentation fault", and now I'm trying to contact the author

upd: found http://www.openldap.org/its/index.cgi/Incoming?id=7586;page=22

All tests crash with Segmentation Fault...
This is normal behavior. The tests do no error checking. The tests are not
meant to be run blindly, you are expected to read their source code.
Ordinarily I only "run" them by single-stepping under gdb so I can examine the
library state at each point.
