Dear all,

I want to plot the excitonic wave-function, But I am getting the error "Segmentation fault''. I post the report file of my BSE calculation.

Also, I download the last version from SVN ''http://www.yambo-code.org/download.php''.

Dear Mojtaba,
are your sure your are using the *last* version of the svn?
Please check thispost and look if your revision is previous of May, 3.
In that case you have to update your source. When compile the new version,
a make clean is needed before recompiling.

Best,

Daniele

Dear all,
I download the last version today(may, 11.) and install yambo of file stable, But I am getting the error:
_________________________________________________________________________
"Fatal Error: Can't open module file 'electrons.mod' for reading at (1): No such file or directory
make[1]: *** [mod_wave_func.o] Error 1
make[1]: Leaving directory `/home/Desktop/2/stable/src/modules'
make: *** [yambo] Error 2
'.
________________________________________________________________________
And when i install yambo of file devel, It is installed. what is there any problems?

Dear Mojtaba,
that sounds strange. Did you performa a make clean before recompiling the new version?

Daniele

Dear Mojtaba

please instal the devel version, we are corecting bugs in this version and not in the old stable one

Claudio

Dear all,
thank you for your reply,
we instal the devel version and that work good.
thank you.

Dear Mojtaba,
we have fixed this compilation issue also in the stable.
So in case you can use that too.

Davide
