Build

Prerequisites

• C++ Compiler: GCC 13+ or Clang 16+ supporting C++23 (as specified in CMakeLists.txt).
• CMake: Version 3.24 or higher.
• LLVM: Version 16+ installed and configured (required for the project, as it uses LLVM libraries).
• Ninja: Version 1.13.2

Build Steps

1. Clone the repository:

   git clone https://github.com/powerangelxd/SakuraE.git
   cd SakuraE

2. Create build directory:

   mkdir build
   cd build

3. Configure with CMake:

   cmake -G Ninja ..

   This will detect LLVM and set up the build with C++23 standard and necessary flags using Ninja.

4. Build the project:

   ninja

5. Create a .sak file in folder build

   touch test.sak

   Then write this program for test:

   func fib(n: int) -> int {
      if (n <= 1) {
         return n;
      }
      return fib(n - 1) + fib(n - 2);
   }
   
   func main() -> int {
      __println("Hello world, check fib(21):");
      return fib(21);
   }

   echo "func fib(n: int) -> int {
    if (n <= 1) {
        return n;
    }
    return fib(n - 1) + fib(n - 2);
   }
   
   func main() -> int {
       __println(\"Hello world, check fib(21):\");
       return fib(21);
   }" >> test.sak

6. Run the compiler (optional test):

   ./SakuraE

If you encounter issues, ensure LLVM development libraries are installed (e.g., llvm-dev package) and llvm-config is available in PATH.
