I'm trying to build some software, and one of the long list of items to install prior to configuring is 'alsa-lib'.
I tried 'sudo apt-get install alsa-lib' but got the message 'E: Unable to locate package alsa-lib' So i looked around on the internet, and saw a page for an alsa-lib package on debian stretch: https://packages.debian.org/source/stretch/alsa-lib I had just installed libjansson-dev, so i didn't think i had anything wrong with my local state, and it had a similar page https://packages.debian.org/sid/libjansson-dev However, the page for jansson identified it as a 'package', while the page for alsa-lib identified it as a 'source package'. So i suppose that a source package needs to be installed in some other way, different than the way a 'package' is installed? It's conceivable that i already somehow have alsa-lib installed in some form (e.g., 'dpkg --get-selections' shows i have an alsa-utils). Anyhow, would appreciate any clues. I imagine that what i need are the libraries and the include files in order to build this other software that asks for alsa-lib. Thanks for any info! dan
