Dear developer,

I am trying to compile Yambo version 4.3.3 and encounter the following error:
Can you please assist us?

Dear khyeoh,
please sign your post with your name and affiliation, this is a rule of the forum. You can do once for all by filling the signature in the user profile.
First, note that 4.3.3 is a very old release of Yambo and it is not maintained anymore, so I strongly suggest you update to a newer release.
Yambo uses several libraries, if they are not present in your machine it downloads them from the network and compile them automatically: now it seems you have a problem at this stage. As reported in the error message you should check if you have direct access to the internet, and wget/curl installed.
If this is the case, it is also possible that the location of the library has changed. In all the cases I strongly advise you to switch to a more recent version of Yambo and if you still have problem, please report here.

Best,
Daniele
