ld: cannot find -lgfortran

[David-Duffy]

I have only just installed gcc-10 (under Android 10), and ran the setupgcc-10.sh script and can see ls -l libgf* libgfortran.so -> /data/data/com.termux/file/usr/lib/libgfortran.so.5

But I don't have libgfortran.so.5 or any others. Do I have to install an earlier version first?

Cheers, David Duffy,

apt install libgfortran5

Remove "sources.list or add " from README, because pkg overwrites (mirror check) the file and nothing is installed!

I'm not sure if this is relative to the issue but whilst trying to; pip3 install -U sklearn I'm getting;

It seems like its not finding; libgfortran5/termux,now 10.2.0-1 aarch64 [installed] If you need other info just say so. Thanks.
