[sane-devel] Unable to Build Sane Backends

[Wes Rishel]

Thanks to Yuri and Ralph for previous help on this topic

Following the instructions at
https://help.ubuntu.com/community/CompileSaneFromSource on Ubuntu 18.04 I
downloaded backends from
https://gitlab.com/sane-project/backends/-/tree/master/backend

I get to these steps.

./configure --prefix=/usr --libdir=/usr/lib/i386-linux-gnu
--sysconfdir=/etc --localstatedir=/var  --enable-avahi
make
sudo make install

However, there is no file named configure in the download, and whereis
configure shows no Ubuntu command with that name.

There is a file configure.ac but it does have execute permission and it has
lines that being with dnl that bash does not recognize as commands.

Is there some sort of preprocessor that I need to use in order to generate
the configure executable file?

Is there a better source for documentation on how to build sane or at least
sane backends?

Thanks in advance.
