Subject: [gentoo-user] matplotlib build fails: link using /usr/lib instead of /usr/lib64
Date: Wed, 27 May 2020 14:26:15 -0000 (UTC) [thread overview]
Message-ID: <ralta7$1hmn$1@ciao.gmane.io> (raw)
I tried to emerge matplotlib today, and it failed because it's linking
in 32-bit libraries instead of 64 bit ones:

What would cause that?
It doesn't appear that it's being build for both 32-bit and 64-bit targets:
These are the packages that would be merged, in order:
