Recall that earlier the manual discussed how to use an existing toolchain
tarball that had been installed into the default installation
directory, /opt/poky/1.5.1
, 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 this setup, locations for the compiler, QEMU scripts, QEMU binary,
a special version of pkgconfig
and other useful
utilities are added to the PATH
variable.
Also, 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.
Collectively, these conditions allow you to easily use the toolchain outside of the OpenEmbedded build environment on both autotools-based projects and Makefile-based projects. This chapter provides information for both these types of projects.
