Yambo Community Forum

Dear developers,

I am trying to compile Yambo 4.5.2 on my Ubuntu 18 . I downloaded the file and ran the "./configure" in terminal, and then "make yambo ypp interfaces" . and it got completed without any errors. But when I type yambo in my terminal, my system doesn't recognize it and also It's not in the list of installed packages. I tried it with quantum Espresso as well ( "make yambo" ), but it just created the folder and again had the same problem and didn't work.

I don't know what the problem is. Could it be because of the version of my Intel compiler or any other hardware related issues? or I should configure with options?
(I checked my Intel model, it's: Intel® Core™ i5-2430M CPU @ 2.40GHz × 4 )

By the way, could you please list the hardware requirements for this package?

Thanks a lot in advance for your help.
Best,

Dear Niloufar,

if the compilation was successful the yambo executable will be in the bin directory inside the yambo dir.
You can run it by launching PATH_TO_YAMBO_DRECTORY/bin/yambo

If you want to run it just typing yambo in your shell you need to instruct the system to find it, there are several ways to do it:
edit your .bashrc adding this line:
export PATH=$PATH: PATH_TO_YAMBO_DRECTORY/bin/
and then:
> source .bashrc
or
copy or link the executable in a directory included in the $PATH variable e.g /usr/local/bin

or you can configure yambo assigning a prefix:
>./configure --prefix=/usr/local/bin
>make
>make install

Dear Daniele,

thank you a lot for your help, I actually had the path in .bashrc file, so I thought it is OK. But when I copied executable in a directory included in the $PATH variable it worked.
So it is OK now.

Best regards,
Niloufar
