Yambo Community Forum

I am new in YAMBO and I have a question about compiling YAMBO. I installed the Yambo code under pwscf code. The Yambo code compiled successfully, but ypp didn't compile and there was not ypp in my bin directory. How can I compile ypp? What was my mistake?
Thanks in advance

Dear Masoud,
this is not the right place to post your question. For a new question you should open a new topic or reply to a topic with the same issue you are encountering. Anyway, do not worry I will move it later.
About your question, it is not easy to answers as you should describe the step you did to understand what is missing.
Anyway after having run the configure script, by typing :

• make yambo you will compile the yambo code

• make interfaces you will compile the interfaces with abinit and pwsc if you configured it

• make ypp you will compile the ypp utility

If you did that and you do not have the ypp executable you should have received some error in compilations: post the error (together with the config.log) file and we will try to understand what went wrong.

Best,

Daniele

Ok. I've moved the post in the proprier section.

Dear Davide
Thanks for your reply
Now I have ypp in my bin directory. I want to use 'ypp' to analyze the DOS and Band structure. I just finished G0W0 for Si crystal. How can I plot DOS or Band structure? I did "ypp -s e" for DOS but the ypp.in file is empty! How do I call the input parameters for ypp.in and how do I run ypp?
Thanks in advance

Dear Masoud,
please, pay attention where you post your question. This is a question on ypp, there is a forum dedicated and there is no reason to post it in compilation section.
It is very strange your input file is empty. Are you running ypp -s e or ypp -s b in the proper directory, i.e. is there the SAVE directory where you are running it?

Daniele

Dear Daniele
thank you
Yes there is the SAVE directory where I am running it. Also there are output files of yambo such as o.qp and r_HF_and_locXC_em1d_ppa_gw0 in this directory. When I did "ypp -s e" or "ypp -s b" I just saw:

Without any input parameter! Could you please tell me what is my wrong?

Dear Masoud,
from what I can see here:

# GPL Version 3.2.5 Revision 1015

you are using a very old release of Yambo. Note that the online documentation is for version 3.3.0 and 3.4.0.
I think that in the version you are using this features where not implemented.
Please download and compile a recent version of the code and everything should work.
Best,
Daniele
