1. Make sure you have Visual Studio 17 2022 installed or alternatively install the "Buildtools for Visual Studio" (https://aka.ms/vs/17/release/vs_BuildTools.exe) and then select "Desktop development with C++"
2. Install CMake
3. Clone the C3C github repository: `git clone https://github.com/c3lang/c3c.git`
4. Enter the C3C directory `cd c3c`.
5. Set up the CMake build `cmake -B build -G "Visual Studio 17 2022" -A x64 -DCMAKE_BUILD_TYPE=Release`
6. Build: `cmake --build build --config Release`
7. You should now have the c3c.exe
4. Enter the C3C directory: `cd c3c`.
5. Set up the CMake build: `cmake --preset windows-vs-2022-release`
6. Build: `cmake --build --preset windows-vs-2022-release`
You should now have a `c3c` executable.
You should now have a `c3c` executable in `build\Release`.
You can try it out by running some sample code: `c3c.exe compile ../resources/examples/hash.c3`
You can try it out by running some sample code: `c3c.exe compile ../../resources/examples/hash.c3`
Building `c3c` using Visual Studio Code is also supported when using the `CMake Tools` extension. Simply select the `Windows x64 Visual Studio 17 2022` configure preset and build.
*Note that if you run into linking issues when building, make sure that you are using the latest version of VS17.*
#### Compiling on Windows (Debug)
Debug build requires a different set of LLVM libraries to be loaded for which a separate CMake configuration is used to avoid conflicts.
1. Configure: `cmake --preset windows-vs-2022-debug`
2. Build: `cmake --build --preset windows-vs-2022-debug`
You should now have a `c3c` executable in `build-debug\Debug`.
