autogen.sh Generates a configure File that Tries to Call Autoconf macro PKG_CHECK_MODULES

[A-Neal]

The macro should be called in configure.ac, not configure. It threw this error:

./configure: line 3178: syntax error near unexpected token `BASH_COMPLETION,'

I fixed the problem by commenting out the call for the macro in the configure file, and didn't touch configure.ac, which does include the call for the macro. I could then run ./configure without error, generate the makefile, and install i3blocks without any problems.

The fix, though simple, took me a while to realize was the issue, as I don't build from source unless necessary. In this case, the version in the Ubuntu repos was out of date, and I wanted to set block background colors, which was not properly possible in the version hosted in the repos.
I decided to open the issue because none like it had been opened and it seems like that macro being present in configure is in error.

I didn't have pkg-config installed. I resolved this issue with the following:

sudo apt install pkg-config
./autogen.sh
./configure

Then it worked like a charm.
