事发

OS: macOS 14.7

在 sage 之外编译 flatter

brew install cmake mpfr libomp gmp fplll

接着 mkdir build && cd build && cmake ..

错误记录(macOS)

解决方案

询问 CPP 大师: M1saka

于是为 CMake 传递参数，让 clang 不要把重载虚函数的警告作为错误, 顺便传递一些库，避免找不到 lib

macOS 可以使用像我一样的脚本, 提前用 brew 安装好需要的库

mkdir build && cd build
                                                          
cmake -DCMAKE_BUILD_TYPE=Release \
      -DCMAKE_CXX_FLAGS="-Wno-error -Wno-overloaded-virtual -Wno-error=overloaded-virtual -I/opt/homebrew/opt/mpfr/include -I/opt/homebrew/opt/libomp/include -I/opt/homebrew/opt/gmp/include" \
      -DCMAKE_C_FLAGS="-Wno-error -Wno-overloaded-virtual -Wno-error=overloaded-virtual -I/opt/homebrew/opt/mpfr/include -I/opt/homebrew/opt/libomp/include -I/opt/homebrew/opt/gmp/include" \
      -DCMAKE_CXX_FLAGS_RELEASE="-Wno-error -Wno-overloaded-virtual -Wno-error=overloaded-virtual -I/opt/homebrew/opt/mpfr/include -I/opt/homebrew/opt/libomp/include -I/opt/homebrew/opt/gmp/include" \
      -DCMAKE_C_FLAGS_RELEASE="-Wno-error -Wno-overloaded-virtual -Wno-error=overloaded-virtual -I/opt/homebrew/opt/mpfr/include -I/opt/homebrew/opt/libomp/include -I/opt/homebrew/opt/gmp/include" ..

除了 官方的安装说明 所安装的外, 还需安装一些包, 这里一并给出

sudo apt-get install -y build-essential cmake gcc g++ git libblas-dev liblapack-dev libgmp-dev libmpfr-dev libomp-dev

接着 cmake ..
