Apologies if this isn't an appropriate place to post this, but I had some trouble building "guile-gi" ...
I downloaded it from github today: git clone --depth=1 https://github.com/spk121/guile-gi.git How I started the process: cd guile-gi ./bootstrap ./configure ... lots of configure-y stuff ... ./configure: line 5297: syntax error near unexpected token `1.46.0' ./configure: line 5297: `GOBJECT_INTROSPECTION_CHECK(1.46.0)' I have the required packages installed: me@thing ~% apt list --installed | grep libgirepository libgirepository1.0-dev/groovy,now 1.66.1-1 amd64 [installed] me@thing ~% apt list --installed | grep guile-3.0-dev guile-3.0-dev/groovy,now 3.0.4-1.2ubuntu3 amd64 [installed] me@thing guile-gi % apt list --installed | grep build-essential build-essential/groovy,now 12.8ubuntu3 amd64 [installed] # My system: me@thing ~% uname -a Linux thing 5.8.0-50-generic #56-Ubuntu SMP Mon Apr 12 17:18:36 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux me@thing ~% cat /etc/issue Ubuntu 20.10 (Technically, Lubuntu) Any suggestions?
