util-linux build system
|
||
|
|
=======================
|
||
|
|
|
||
|
|
- all util-linux specific autoconf macros use UL_ prefix
|
||
|
|
|
||
|
|
- utils in Makedile.am files are enabled/disabled according to BUILD_<NAME>
|
||
|
|
conditions (AM_CONDITIONAL), for example:
|
||
|
|
|
||
|
|
if BUILD_HWCLOCK
|
||
|
|
...
|
||
|
|
endif
|
||
|
|
|
||
|
|
- all BUILD_<NAME> in configure.am are always based on build_<name> variables,
|
||
|
|
for example:
|
||
|
|
|
||
|
|
AM_CONDITIONAL([BUILD_HWCLOCK], test "x$build_hwclock" = xyes)
|
||
|
|
|
||
|
|
the $build_<name> should be available in whole configure script
|
||
|
|
|
||
|
|
- AC_ARG_ENABLE() status is always stored in $enable_<name> variable, possible
|
||
|
|
setting:
|
||
|
|
|
||
|
|
"check" - util/feature is optional, if any subcomponent (function, lib,
|
||
|
|
...) is missing a warning is printed and the util/feature is
|
||
|
|
disabled
|
||
|
|
|
||
|
|
"yes" - util/feature is required, if any subcomponent (function, lib,
|
||
|
|
...) is missing an error is printed and ./configure aborted
|
||
|
|
|
||
|
|
"no" - the util/feature is unwanted
|
