# This program wraps around pkg-config to generate the correct include and
|
|
|
|
# library paths when cross-compiling using a sysroot.
|
|
|
|
# The assumption is that the sysroot contains the .pc files in usr/lib/pkgconfig
|
|
|
|
# and usr/share/pkgconfig (relative to the sysroot) and that they output paths
|
|
|
|
# relative to some parent path of the sysroot.
|
|
|
|
# This assumption is valid for a range of sysroots, in particular: a
|
|
|
|
# LSB-compliant root filesystem mounted at the sysroot, and a board build
|
|
|
|
# directory of a Chromium OS chroot.
|
|
|
|
# Additional directories containing .pc files may be specified by setting
|
|
|
|
# the PKG_CONFIG_PATH environment variable- these will be prepended to the
|
|
|
|
# generated paths.
