This gives a base for your own civicc compiler.

First make sure you have all dependencies installed. The full dependencies of CoCoNut are listed on the main GitHub repository. On Ubuntu these can be installed using:

sudo apt update && sudo apt install build-essential cmake bison flex graphviz

For macOS, see macOS dependencies.

Now clone this repo:

git clone [email protected]:CoCoNut-UvA/civicc-skeleton.git civicc
cd civicc
./configure.sh

If everything went correctly, a build-debug directory is created. Run

make -C build-debug

to build your compiler.

IMPORTANT: After cloning, you should change the remote to point to a private repo you control. You can not achieve this via forking, because GitHub does not allow changing the visibility of a forked repo.

For syntax highlighting of the CoCoNut DSL files (e.g. the main.ccn file), you can install the nutcracker extension from the Visual Studio Marketplace here.

We provide a Linux configuration file in .vscode/c_cpp_properties.json that helps IntelliSense to find the header files generated by cocogen. VS code should pick this up automatically; if you open a C file you should see CoCoNut-Linux in the bottom-right corner.

You can quickly create an archive for submitting to canvas as follows

make dist

this gets everything in your git repo and combines it with the used coconut version in one archive. This should contain everything needed to hand in your assignments. NOTE: Always check the resulting archive if it contains everything and builds correctly.

If you just want ASAN to not report memory leaks (although we do recommend that you actually fix the leaks), you can add the following to src/main.c:

/* Do not detect memory leaks when using AddressSanitizer. */
const char *__asan_default_options() {
    return "detect_leaks=0";
}

If you want to disable it entirely, edit the debug configuration in the Makefile. You may need to remove the build-debug folder and rerun ./configure.sh.

The following build dependencies are required on macOS:

brew install cmake coreutils binutils bison graphviz gnu-tar

You might also need to run the following for cmake to find Bison:

echo "export PATH=\"$(brew --prefix)/opt/bison/bin:\$PATH\"" >> ~/.zshrc

Note: Make sure to fully restart your terminal after adding this line to .zshrc, and also delete the folder coconut/build if it exists. Otherwise cmake will keep using the old unsupported Bison version that macOS ships with.
