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.
