Koala C

The tool koala-c translates the bindings defined in a Koala composition to C. The program takes as input a Koala composition and produces as output a set of .c/.h files, and a Makefile. This tool corresponds to the combination of koala / koalamaker tools of the original Philips Koala compiler.

The generated files will be stored in the directory specified with the '-d' command line switch (defaults to current working directory).

   koala-c -I <directory with Koala components> \
           -i <top-level component> \
           -d <output-dir>

The C-source source files can now be compiled into an executable program a.out by running make in the output directory:

   cd <output-dir>
   make
   ./a.out

All non-generated compilation units (i.e., all source files corresponding to Koala modules), should be stored in the same location as the corresponding component definition file. This is how koala-c knows where source files can be located and how source files are referenced in generated Makefiles. This is based on Philips' Koala implementation.

The name of the output program (i.e., the result of running make), can be specified with the '-p' switch:

   koala-c -I <directory with Koala components> \
           -i <top-level component> \
           -d <output-dir> \
           -p hello-world

The name of the generated Makefile can be specified with the '-m-' switch:

   koala-c -I <directory with Koala components> \
           -i <top-level component> \
           -d <output-dir> \
           -p hello-world  \
           -m Mymake

Compiling and running the resulting program can now be performed as follows:

   cd <output-dir>
   make -f Mymake
   ./hello-world

The generated Makefile contains two additional targets. These are:

• clean to remove files generated during the invocation of =make
• allclean to also remove the files generated by koala-c
