Note for Windows users with recent Cygwin:
|
||||
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 =

|

|

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 (4 properties) in this file (build.xml).
|
||||
When all tests pass, the settings should be entered into the COOJA External tool settings dialog.
|
||||
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
|
||||
> ant level2
|
||||
|
||||
For more information including configuration examples:
|
||||
> ant help
|
||||
> ant help
|
||||
|
||||
> ant level2
|
||||
Runs JNI test level 2:
|
||||
[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 level3
|
||||
Runs JNI test level 3:
|
||||
[map file parsing test]
|
||||
Compiles java + c.
|
||||
The map file is parsed, and information about data+bss sections is outputted.
|
||||
> ant level3a
|
||||
[address parsing using map file]
|
||||
|
||||
> ant level3b
|
||||
[address parsing using nm]
|
||||
|
||||
> ant level4
|
||||
Runs JNI test level 4:
|
||||
[fetching reference var]
|
||||
Calculates offset between relative (mapfile) and absolute memory.
|
||||
Calculates offset between relative and absolute memory.
|
||||
A simple native function increases two counters (from both data and bss sections).
|
||||
|
||||
> ant level5
|
||||
Runs JNI test level 5:
|
||||
[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.
