Proof of Concept Compiler Independent Interface (CII)

This shows how it is somehow possible to mix compilers.

• foo -> Class compiled with our "main compiler"

• main.cpp -> Program Entry Point using our "main compiler"

• foo_cii -> Compiler Independent Interface for class foo. Compiled with our "main compiler"

• foo_manip -> Shared Library compiled with "foreign compiler" and thus also needs compiler idependent functions (can be seen as entry point/wrapper to libraries developed with foreign compilers). Uses foo_cii to handle Objects of class foo compiled with "main compiler".

Use test_foo.sh in the root directory to rebuild project and run the test executable. G++ and CLANG need to be installed on the system.

Requirements for a CII:

• Functions declarations without name mangeling (because name mangeling is compiler dependent)
• Functions declarations only using basic standard datatypes (no C++ datatypes, because their byte size and alignment is compiler dependent)

Run test:

Tested and developed on Debian 10

First install compilers:

sudo apt install g++ clang

Run script

./test_foo.sh

Bonus:

If a CII exits, it is easily possible to create bindings to high level languages like JAVA, C#, etc.
