The majority of problems encountered during these tests are related to
the compilation and linking stage of the Contiki libraries.
Below follows a number of configurations that work for different users.
Linux users with the GNU toolchain may try:
2007-09-12 14:39:31 +02:00
COMPILER_ARGS =
LINK_COMMAND_1 = gcc -shared -Wl,-Map=$(MAPFILE) -o $(LIBFILE)
LINK_COMMAND_2 =
PARSE_WITH_NM=false
2007-09-10 19:50:47 +02:00
Windows users with recent Cygwin may try:
COMPILER_ARGS = -mno-cygwin -Wall -I'$(JAVA_HOME)/include' -I'$(JAVA_HOME)/include/win32'
LINK_COMMAND_1 = gcc -mno-cygwin -shared -Wl,-Map=$(MAPFILE) -Wl,--add-stdcall-alias -o $(LIBFILE)
LINK_COMMAND_2 = -L/usr/lib/mingw -lmsvcrt
Windows users with older Cygwin may try:
COMPILER_ARGS = -mno-cygwin -I'$(JAVA_HOME)/include' -I'$(JAVA_HOME)/include/win32'
LINK_COMMAND_1 = ld -Map=$(MAPFILE) -shared --add-stdcall-alias /usr/lib/mingw/dllcrt2.o -o $(LIBFILE)
LINK_COMMAND_2 = -L/usr/lib/mingw -lmingw32 -lmingwex -lmsvcrt
Windows users with recent Cygwin and separate MinGW tools may try:
In recent (early 2007) MinGW-Cygwin versions, the JNI support has been limited.
This may cause COOJA not to be able to load libraries generated using gcc's -mno-cygwin flag.
One possible solution is to download "real" MinGW (http://www.mingw.org), and install it separately
from Cygwin (for example in c:\mingw). Try using the following settings:
COMPILER_ARGS = -Wall -D_JNI_IMPLEMENTATION_ -I'$(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 =
2007-09-10 19:50:47 +02:00
Mac users may try:
COMPILER_ARGS = [PENDING]
LINK_COMMAND_1 = [PENDING]
LINK_COMMAND_2 = [PENDING]

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!

<echo>
Run either
> ant level3a
or
> ant level3b
3a tests parsing library addresses using the map file generated at link time.
3b tests parsing library addresses using the nm tool.
At least one of the tests must pass.
After passing, the 'exttools.cfg' must be updated.
The external tools setting:
PARSE_WITH_NM=true
causes COOJA (and the following tests) to use nm to parse library addresses,
and should be used if test 3b passed.
PARSE_WITH_NM=false
causes COOJA to parse the generated map file, and should be used if test 3a passed.
