Recall that earlier the manual discussed how to use an existing toolchain
tarball that had been installed into the default installation
directory, /opt/poky
, which is outside of the
Build Directory
(see the section "Using a Cross-Toolchain Tarball)".
And, that sourcing your architecture-specific environment setup script
initializes a suitable cross-toolchain development environment.
During the setup, locations for the compiler, QEMU scripts, QEMU binary,
a special version of pkgconfig
and other useful
utilities are added to the PATH
variable.
Variables to assist pkgconfig
and autotools
are also defined so that,
for example, configure.sh
can find pre-generated
test results for tests that need target hardware on which to run.
These conditions allow you to easily use the toolchain outside of the
OpenEmbedded build environment on both autotools-based projects and
Makefile-based projects.
