Instal py3cairo untuk Python 3.6

Saya mencoba menginstal pygobject, tetapi salah satu dependensinya adalah py3cairo. Saya sudah menginstalnya untuk digunakan dengan Python 3.4, tapi sekarang saya ingin menggunakannya dengan Python 3.6.

Saya tahu saya dapat menginstalnya dengan sudo apt-get install python3-cairo, tetapi dikatakan sudah terinstal:

$ sudo apt-get install python3-cairo

Mencoba membangun/memasangnya dari sumber itu jelek, karena saya mendapatkan semua jenis masalah:

Saya mencoba melakukan hal yang sama, kompilasi pycairo dengan python3.6, di Slackware 14.2. Saya mendapatkan kesalahan yang sama seperti Anda, dan tidak satu pun dari berbagai patch waf yang disebutkan berfungsi.

Saya berhasil membuat satu kemajuan dalam pengejaran ini. Distro slackware saat ini memiliki skrip waf yang sepertinya berjalan. Itu ada di http://ftp.slackware.com/pub/slackware/slackware-current/source/l/pycairo/

Kesalahan di atas yang Anda sebutkan tidak ada dalam skrip ini, tetapi kesalahan lain muncul ketika mencoba mengkompilasi dengan kesalahan di cairomodule.c.

Versi slackware saat ini hampir berhasil, namun masih gagal dengan kesalahan kompilasi. Mungkin seseorang yang lebih berpengalaman dengan lib bisa memperbaikinya.
