如何从 VCPKG 运行的 cmake 中删除 ninja 的 c++ 编译标志？

编程问答 2022-05-23

问题描述

我正在尝试使用 boost-container 在 RaspBerry Pi 4 上构建 VCPKG package manager。 问题是编译标志 -m64 之一对于 rpi 上的编译器无效（但对于 PC 是可以的），所以我需要删除该标志。这非常困难，因为 VCPKG 使用 cmake，使用 ninja 进行构建，而 ninja 使用 b2 构建 boost。

我需要 VCPKG 的版本：ebe505081b667a9f9a56596057f63ed20be237a5。所以要在 RPI 上重现问题：

git clone https://github.com/microsoft/vcpkg.git
cd vcpkg/
git checkout ebe505081b667a9f9a56596057f63ed20be237a5
./bootstrap-vcpkg.sh -useSystemBinaries # for that version it is necessairy for RPI
./vcpkg install boost-container

运行上面的命令后，我发现 -m64 标志有问题：

Additionally,attach any relevant sections from the log files above.

But the problem was:

我检查了工作目录：

find /home/agh/vcpkg/buildtrees/boost-container/x64-linux-dbg -type f | xargs grep m64

但是没有什么可以删除我注意到的标志。

我发现的唯一解决方案是创建编译器包装二进制文件，它只忽略那个标志 -m64 - 但我希望这是为 boost-contaier 的 CMake 创建补丁的更好解决方案？
