configure: add the --libdir option
|
||
|
|
|
||
|
|
This commit allows users/packagers to choose a lib directory to store
|
||
|
|
iproute2 lib files.
|
||
|
|
|
||
|
|
At the moment iproute2 ship lib files in /usr/lib and offers no way to
|
||
|
|
modify this setting. However, according to the FHS, distros may choose
|
||
|
|
"one or more variants of the /lib directory on systems which support
|
||
|
|
more than one binary format" (e.g. /usr/lib64 on Fedora).
|
||
|
|
|
||
|
|
As Luca states in commit a3272b93725a ("configure: restore backward
|
||
|
|
compatibility"), packaging systems may assume that 'configure' is from
|
||
|
|
autotools, and try to pass it some parameters.
|
||
|
|
|
||
|
|
Allowing the '--libdir=/path/to/libdir' syntax, we can use this to our
|
||
|
|
advantage, and let the lib directory to be chosen by the distro
|
||
|
|
packaging system.
|
||
|
|
|
||
|
|
Note that LIBDIR uses "\${prefix}/lib" as default value because autoconf
|
||
|
|
allows this to be expanded to the --prefix value at configure runtime.
|
||
|
|
"\${prefix}" is replaced with the PREFIX value in check_lib_dir().
