These brief instructions will help you get started to install FPChecker.
Edit me
To install with Spack instead of CMake, see ./installation_spack.html
Requirements
- A Linux system is required to run FPChecker. Support for macOS is coming soon.
- FPChecker is developed as an extension of the clang/LLVM compiler. To build FPChecker, one of the following versions of clang/LLVM must be already installed:
- clang/LLVM 12.0
- clang/LLVM 13.0 (will be supported soon)
- Python 3
- To run the tests, pytest (see here) is needed.
Source Code
The source is available at github: https://github.com/LLNL/FPChecker
Checkout FPChecker:
$ git clone https://github.com/LLNL/FPChecker.git
Building
FPChecker can be built using a recent version of cmake. Support to build via Spack is coming soon.
$ mkdir build
$ cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/path/to/install ..
$ make && make install
Note: Note that cmake will attempt to search for
clang++ and llvm-config in your environment. So make sure these commands are visible in the environment before building.Testing
To run the tests, use ctest in the build directory:
$ ctest -V
