So I gave up on NETCDF and compiled without it. That worked fine, but now, after I run P2Y, I run YAMBO -i -V RL and get the following

No NETCDF support. It is not possible to verify if the present database is compatible
with the current Yambo version. Re-create the DB1 databases with the NETCDF support and try again

How to I eliminate NETCDF from the process since YAMBO (4.0) doesn't work with it on my machine?

Dear Jeff,
sorry I have overlooked your previous message.
It is not possible to eliminate the netcdf support in the 4.0. Anyway the problem you are experiencing, even if it appears as a Netcdf error
it is a general I/O issue not related to the netcdf library.
This problem should have been fixed in the last svn release. Are you running the latest svn?
If the problem persists please let us know. As a workaround, avoiding to write the dipoles (DBsIOoff= "DIP") should permit you to run the calculation.
Sorry for that, 4.0 is still a devel version and we are working to make it stable.

Best,

Dear Jeff,
I just realized that the problem has been fixed in the our trunk version and not yet into the GPL version.
We will do very soon, a new gpl release containing some bug fixes, including this one.

Best,
Daniele

Thanks Daniele

I took your advice and set the recommended variable to off. This has cured my particular problem for all the parallelization configurations (so far). I look forward to the fixes.

Dear Jeff and all people comtributing to this thread,
this is to inform you that a new release of yambo containing many bug fixes has been released.
For the moment the nre version is in the svn repository only, in the next day we will also prepare the tarball and the release note.
Please note this is still a devel version, and we will be very glad if you could report us any problem you encounter.
