Linux users with the GNU toolchain often can use:			
	COMPILER_ARGS = [PENDING]
	LINK_COMMAND_1 = [PENDING]
	LINK_COMMAND_2 = [PENDING]
			
Cygwin users may try:
	COMPILER_ARGS = [PENDING]
	LINK_COMMAND_1 = [PENDING]
	LINK_COMMAND_2 = [PENDING]

Windows users with recent Cygwin:
In recent (early 2007) MinGW-Cygwin versions, the JNI support has been removed/limited.
This may cause COOJA not to be able to load libraries generated using gcc's -mno-cygwin flag.
One possible solution is to download "real" MinGW (http://www.mingw.org), and install it separately
from Cygwin (for example in c:\mingw). Try using the following settings:

	COMPILER_ARGS = -Wall -D_JNI_IMPLEMENTATION_ -I'$(JAVA_HOME)/include' -I'$(JAVA_HOME)/include/win32'
	LINK_COMMAND_1 = gcc -shared -Wl,-Map=$(MAPFILE) -Wall -D_JNI_IMPLEMENTATION_ -Wl,--kill-at -o $(LIBFILE)
	LINK_COMMAND_2 =

The COOJA Simulator - JNI Tests
-------------------------------

These tests can be used to help understand COOJA errors, and to configure COOJA for new users.
For COOJA to compile JNI libraries successfully, tests 2-5 must be completed.
In level3, only level3a or level3b is necessary to pass.

You may have to change the configuration in the file 'exttools.cfg'.
When all tests pass, these settings should be entered into the COOJA External tool settings dialog.

Before running the tests, the COOJA JAR file must be created:
> ant compile_cooja
			
To run the first test:
> ant level2

For more information including configuration examples:
> ant help

> ant level2
	[compilation test]
	Compiles level2.c to level2.library, using both c compiler and linker.
	Java class loads the library and calls a simple native function.

> ant level3a
	[address parsing using map file]

> ant level3b
	[address parsing using nm]

> ant level4
	[fetching reference var]
	Calculates offset between relative and absolute memory.
	A simple native function increases two counters (from both data and bss sections).

> ant level5
	[fetches and restores memory segments - the final test]
	A simple native function increases two counters (from both data and bss sections).
	The current memory (data+bss sections) is fetched and restored between function calls.
	The counters should be restored with the memory!
