Install documentation for GCC on Debian Buster
If you source.list
only contains the following standard sources for Debian Buster, there will be no man pages for your GCC compilers.
deb http://mirrors.163.com/debian/ buster main contrib non-free
deb-src http://mirrors.163.com/debian/ buster main contrib non-free
deb http://security.debian.org/debian-security/ buster/updates main contrib
deb-src http://security.debian.org/debian-security/ buster/updates main contrib
deb http://mirrors.163.com/debian/ buster-updates main contrib non-free
deb-src http://mirrors.163.com/debian/ buster-updates main contrib non-free
To install the documentation for GCC, you need to add backports to your source.list
as below, where the contrib
category contains the package gcc-doc
and the non-free
category contains the package gcc-8-doc
.
deb http://mirrors.163.com/debian/ buster-backports main contrib non-free
The meaning of backports can be referred to here.
Backports are recompiled packages from testing (mostly) and unstable (in a few cases only, e.g. security updates) in a stable environment so that they will run without new libraries (whenever it is possible) on a Debian stable distribution.
Backports cannot be tested as extensively as Debian stable, and backports are provided on an as-is basis, with risk of incompatibilities with other components in Debian stable. Use with care!
