# Generic build profile.sh for all platforms, works in bash, sh, and ksh.

#

# Copy this file to your own area, and edit it to suit your needs.

#

# Ideally you either won't need to set the ALT_* variables because the

#   build system will find what it needs through system provided paths

#   or environment variables, or you have installed the component in the

#   recommended default path.

#

# If you find yourself forced to set an ALT_* environment variable and

#   suspect we could have figured it out automatically, please let us know.

#

# Most ALT_* directory defaults are based on being in the parent directory in

#    ALT_SLASH_JAVA, so it's possible to create for example a "C:/jdk6"

#    directory, assign that to ALT_SLASH_JAVA, and place all the components

#    in that directory. This could also minimize the ALT_* environment

#    variables you need to set.

#

#

# Assumes basic unix utilities are in the PATH already (uname, hostname, etc.).

#

# On Windows, assumes PROCESSOR_IDENTIFIER, VS100COMNTOOLS,

#   SYSTEMROOT (or SystemRoot), COMPUTERNAME (or hostname works), and

#   USERNAME is defined in the environment.

#   This profile does not rely on using vcvars32.bat and 64bit Setup.bat.

#   Uses CYGWIN cygpath to make sure paths are space-free.

#

# The JDK Makefiles may change in the future, making some of these

#   settings unnecessary or redundant.

#

# This is a working example, but may or may not work on all systems.
