# buildksh93.readme

#

* Intro:

"buildksh93.ksh" 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 }) which are

moved later to their matching OS/Net build directories.

* Note that buildksh93.ksh 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://www.research.att.com/sw/download/beta/INIT.2007-04-18.tgz'

$ wget --http-user="I accept www.opensource.org/licenses/cpl" --http-passwd="." 'http://www.research.att.com/sw/download/beta/ast-ksh.2007-04-18.tgz'

## Unpack the sources (32bit SPARC):

$ mkdir build32_sparc

$ cd build32_sparc

$ gunzip -c ../INIT.2007-03-28.tgz | tar -xf -

$ gunzip -c ../ast-ksh.2007-03-28.tgz | tar -xf -

## Build ast-ksh for 32bit SPARC (build other build flags are:

# - "build.solaris.sparc.32bit.suncc" - 32bit SPARC

# - "build.solaris.sparc.64bit.suncc" - 64bit SPARC

# - "build.solaris.i386.32bit.suncc" - 32bit x86/i386

# - "build.solaris.i386.64bit.suncc" - 64bit x86/AMD64

# )

$ time nice ksh ../buildksh93.ksh "build.solaris.sparc.32bit.suncc" 2>&1 | tee -a buildlog.log

## Test ksh93

$ time nice ksh ../buildksh93.ksh "testshell" 2>&1 | tee -a buildlog.log

## Generated binaries and headers can be found in the arch/$(PLATFORM)/

## subdirectory.
