Cibyl is an environment to compile and run programs written in C, Objective-C, C++ and possibly Fortran on J2ME phones. It is documented on the project page at

http://cibyl.org

and the source code can be found on github:

http://github.com/SimonKagstrom/cibyl

Prerequisites

You need the following to use Cibyl:

• unzip, gcc, g++, tar, gzip, make, cmake
• Python (2.3, 2.4 tested)
• The Jasmin assembler (http://jasmin.sourceforge.net)
• A Java compiler / runtime environment
• The jasmin java assembler (http://jasmin.sourceforge.net)
• For J2ME support, MIDPath (http://midpath.thenesis.org) or the Sun Wireless Toolkit

Building Cibyl

To setup Cibyl, do the following steps:

1. Download a pre-built toolchain from http://cibyl.org. In this case you can skip directly to step 2.

   Alternatively, build it first using the following command:

   cd toolchain make # (this will take some hours)

2. Unpack the toolchain

   cp cibyl-bin-PLATFORM-VERSION.tar.bz2 /path/to/install/dir tar -xjf cibyl-bin-PLATFORM-VERSION.tar.bz2

3. Add the Cibyl binaries to your path:

   export PATH=$PATH:/path/to/install/dir/mips-cibyl-elf/bin

   If you downloaded the pre-built toolchain, you can stop here.

4. Build the translator and the cibyl libraries

   mkdir build cd build cmake ../ make && make install

   this will install the libraries and tools in /path/to/install/dir

5. Build the examples by e.g.,

   cd examples/host-java/hello-world make

6. To build a J2ME example, do

   6.1 For windows:

   cd examples/j2me/hello-world make -f Makefile.cygwin

   6.2 For other platforms:

   cd examples/j2me/hello-world make
