#  This shell script is a wrapper to launch the NDK build from the
#  command-line inside an application project path.
#
#  Typical usage is:
#
#     cd $PROJECT_PATH
#     ndk-build
#
#  Assuming that the Android NDK root path is in your PATH. However,
#  you can also invoke it directly as:
#
#     $NDK_ROOT/ndk-build
#
#  This really is a tiny wrapper around GNU Make.
#

# Ensure we get the full path of this script's directory
# this is needed if the caller uses the -C <path> GNU Make
# option, as in:
#
#    cd ndk
#    ./ndk-build -C <project-path>
#
PROGDIR=`dirname $0`
PROGDIR=`cd $PROGDIR && pwd`

# if GNUMAKE is not defined in the environment, use 'make'
if [ -z "$GNUMAKE" ] ; then
    GNUMAKE=make
fi

# On Windows, when running under cygwin, check that we are
# invoking a cygwin-compatible GNU Make binary. It is unfortunately
# common for app developers to have another non-cygwin compatible
