Hello,
I am trying to build LMDB libraries from source on SUSE Linux using gcc 4.7.2
to try for an experimental project at work. I am getting some build errors. I
see pthread.h and libpthread.{a/so} installed in /usr/include and /usr/lib64,
respectively. But I do not see these functions in the header file or in the
library. Maybe the pthread library version is old. I am not sure. I tried
searching on the web, but I was not able to understand how to install a
different version of the pthread library (it seems to come packaged with the
OS?). I do not have admin rights so I would try installing in my local area.
Can someone please advise on things I can try to resolve this issue? Thank you
for your time and help.
(P.S. I had built LMDB successfully on a Mac OS X machine (home computer)
without any issues)
