Building Clang/LLVM on Windows from source code can be a complex process. Here's a general outline of the steps involved:
Install the necessary dependencies:
- CMake: Download and install CMake from the official website.
- Ninja (optional): Download and install Ninja build system from the official website. Ninja is recommended for faster builds, but it's not strictly required.
Clone the LLVM source code repository:
- Open a command prompt and navigate to the directory where you want to clone the LLVM repository.
- Run the following command to clone the repository:bash
git clone https://github.com/llvm/llvm-project.git
Configure the build:
- Create a build directory (e.g.,
build
) within the LLVM source code directory. - Open a command prompt and navigate to the build directory.
- Run the following CMake command to configure the build:
Replacearduinocmake -G "Visual Studio 16 2019" -DLLVM_ENABLE_PROJECTS="clang" -DLLVM_TARGETS_TO_BUILD="X86" <path_to_llvm_source_code>
<path_to_llvm_source_code>
with the actual path to the LLVM source code directory.
- Create a build directory (e.g.,
Build the project:
- Open the generated Visual Studio solution file (
LLVM.sln
) in Visual Studio. - Build the solution using the appropriate configuration and target platform (e.g.,
Release
,x64
). - Alternatively, if you have installed Ninja, you can build from the command line using the following command:
Replacemathematicaninja -C <path_to_build_directory>
<path_to_build_directory>
with the actual path to the build directory.
- Open the generated Visual Studio solution file (
Install Clang/LLVM:
- After the build process completes successfully, you can install Clang/LLVM by running the following command from the build directory:
This will install Clang/LLVM to the default installation directory.ninja install
- After the build process completes successfully, you can install Clang/LLVM by running the following command from the build directory:
Please note that building Clang/LLVM on Windows can be a time-consuming process, and it may require significant system resources. Make sure you have enough disk space, memory, and CPU power to complete the build successfully.
For more detailed instructions and options for building Clang/LLVM on Windows, refer to the official LLVM documentation: https://llvm.org/docs/GettingStarted.html
