Dependency

• C++17 compiler
• CMake
• zfstream.hpp uses boost::iostreams
• itertools.hpp uses boost::coroutine2
• getopt.hpp uses boost::program_options
• grn.hpp uses boost::graph
• eigen.hpp uses Eigen
• zlib.hpp uses zlib

Installation

The easiest way is to use Homebrew:

brew install heavywatal/tap/cxxwtl

Alternatively, you can get the source code from GitHub, and install it with CMake:

git clone https://github.com/heavywatal/cxxwtl.git
cd cxxwtl/
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=${HOME}/local
cmake --build build
cmake --install build

Header files are installed to ${CMAKE_INSTALL_PREFIX}/include/wtl/. This library can be imported from other CMake projects:

find_package(wtl)
target_link_libraries(${YOUR_TARGET} PRIVATE wtl::wtl)

Usage

// example.cpp
#include <iostream>
#include <wtl/math.hpp>

int main() {
    std::cout << wtl::factorial(5) << std::endl;
    return 0;
}

Additional include path can be specified with -I option or CPATH environment variable.

clang++ -std=c++17 -O2 -Wall -Wextra -Wpedantic -I${HOME}/local/include example.cpp
./a.out
