Yambo Community Forum

Dear developers,

I am new to YAMBO and I am trying to follow the example of hBN_2D downloaded from the yambo tutorial website.
I run successfully the DFT, q2y and yambo initialization, but failed when I was trying to run the photonic spectra by the yambo.in generated by yambo -o c -k hartree, with the error information,

Could you please tell me how to fix this problem? Thank you!

Dear Hao,
please sign your post with your affiliation, this is a rule od the forum. You can do once for all, by filling the signature field in your profile.
A possibility of the error is something weird in the compilation.
You can try to recompile yambo adding the following option in the configure:
./configure --enable-int-linalg --other_options

to see if there is some incompatibility in the linear algebra libraries you are linking.
If the problem persist, please post here your config.log file.

Remember to do a
make clean_all
before recompiling,


Best,
Daniele

it works now. thank you!
