In addition to the general development tools and compilers, a set of
custom tools called "onbld" is also required. This includes scripts and
programs that handle compiler and assembler compatibility, CTF
data, ABI auditing, installation of ON bits, and more. Many of
these utilities are platform-specific; therefore, we deliver a version
of the SUNWonbld package for all supported platforms (currently x86 and
SPARC). Note that these tools are built from sources in the
usr/src/tools subdirectory of the ON source gate. Refer to the Tour
of Your ON Workspace in section 3.2 for more information about location
of the sources. If you have the sources available, you can get by
without installing SUNWonbld; however, you may encounter dependency
problems when bootstrapping your ON installation. You can obtain this
package from http://opensolaris.org/os/downloads/on/. Be aware
that certain versions of onbld may be required to build certain ranges
of ON sources; if you need to work with an older version of the source,
be sure to check the onbld version requirements for that version.
The ON-specific build tools are delivered as a SVR4 (pkgadd(1M))
package for each supported build machine architecture. The package
installs into /opt/onbld.
