Hi igraph users,
I have problems installing python-igraph via pip for Python 3. At some point the compiler fails with:

cc1: some warnings being treated as errors
error: command 'gcc' failed with exit status 1
Note the "cc1: some warnings being treated as errors“ - if a warning is the cause of the failed compilation, can this be switched off?
The error is also described here:
Can anyone help? Thank you Christian
