Subject: [PATCH] Add support for multiple sysroots
|
|
|
|
Introduce PKG_CONFIG_SYSROOT_BASE, which can be set to a base directory
|
|
under which multiple install prefixes exist.
|
|
|
|
Now it's possible to:
|
|
* configure and install libfoo with --prefix=/base/foo/usr
|
|
* configure and install libbar with --prefix=/base/bar/usr
|
|
* export PKG_CONFIG_SYSROOT_BASE=/base
|
|
|
|
and pkg-config attempts to detect the sysroot directory for each .pc
|
|
file located under the base directory, and sets its sysroot accordingly.
|
|
|
|
Example with libfoo.pc and libbar.pc both contain includedir=/usr/include
|
|
|
|
$ PKG_CONFIG_PATH=/base/foo/usr/lib/pkg-config:/base/bar/usr/lib/pkgconfig \
|
|
PKG_CONFIG_ALLOW_SYSTEM_CFLAGS=1 \
|
|
pkg-config --cflags libfoo libbar
|
|
|
|
Will print "-I/base/foo/usr/include -I/base/bar/usr/include"
