The package to install is often called python3-devel, but that name
|
|
might be different in your distribution. Note that if you do not plan
|
|
to use Spot's Python bindings, you may also disable their compilation
|
|
by running
|
|
./configure --disable-python
|
|
and in this case you do not need python3-devel installed.])])
