* Intro:
"buildksh93.sh" is a small build script used to build the AT&T "ast-ksh"
and "ast-open" packages using its native (nmake-based) build system
which is needed to build the iffe-generated (header) files (each time
for { 32bit SPARC, 64bit SPARC, 32bit i386, 64bit AMD64, 32bit S390,
64bit S390x }) which are moved later to their matching OS/Net build
directories.
THIS SCRIPT IS NOT INTENDED FOR NORMAL USAGE.
* Note that buildksh93.sh modifies the build behaviour of the AST build
system, including enforcing C99/XPG6 semantics (which is MANDATORY!!)
and feeding additional libraries (like libnsl, libsocket, librt etc.)
to the feature look system (called "iffe" (="if feature exists")) to
ensure all features needed for the Solaris version of ksh93 are
properly found.
* Example usage of the script (more information can be found in the
script itself):
## Download AT&T ksh93 sources
$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www2.research.att.com/~gsf/download/tgz/INIT.2011-02-08.tgz'
$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www2.research.att.com/~gsf/download/tgz/ast-ksh.2011-02-08.tgz'
$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www2.research.att.com/~gsf/download/tgz/ast-open.2011-02-08.tgz'
## Unpack the sources (32bit SPARC):
$ mkdir build_sparc_32bit
$ cd build_sparc_32bit
$ gunzip -c <'../INIT.2011-02-08.tgz' | tar -xf -
$ gunzip -c <'../ast-ksh.2011-02-08.tgz' | tar -xf -
## Build ast-ksh for 32bit SPARC
# (build other build flags are:
# - 'build.debug.solaris.sparc.32bit.suncc' - 32bit SPARC
# - 'build.debug.solaris.sparc.64bit.suncc' - 64bit SPARC
# - 'build.debug.solaris.i386.32bit.suncc' - 32bit x86/i386
# - 'build.debug.solaris.i386.64bit.suncc' - 64bit x86/AMD64
# - 'build.debug.solaris.s390.32bit.gcc' - 32bit SystemZ/S390
# - 'build.debug.solaris.s390.64bit.gcc' - 64bit SystemZ/S390x
# )
## Test ksh93:
$ time nice ksh ../buildksh93.sh 'testshell' 2>&1 | tee -a buildlog.log
## Generated binaries and headers can be found in the arch/$(PLATFORM)/
## subdirectory.
