我正在尝试使用VCPKG 包管理器在Raspberry Pi 4上构建boost-container。问题是编译标志之一对 rpi 上的编译器无效（但对 PC 来说可以），所以我需要删除该标志。这是极其困难的，因为 VCPKG 使用 cmake，用 ninja 构建，它用于构建 boost。-m64b2

我需要有 VCPKG: 的版本ebe505081b667a9f9a56596057f63ed20be237a5。所以要重现 RPI 上的问题：

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，我看到-m64标志有问题：

Please ensure you're using the latest portfiles with `.\vcpkg update`, then
submit an issue at https://github.com/Microsoft/vcpkg/issues including:
  Package: boost-container:x64-linux
  Vcpkg version: 2019.09.12-unknownhash

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

But the problem was:
gcc.compile.c /home/agh/vcpkg/buildtrees/boost-container/x64-linux-dbg/boost/build/e3cde813a01d557174a1b469417f2150/alloc_lib.o

我检查了工作目录：

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

但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，它只忽略一个标志-m64- 但我希望为 boost-contaier 的 CMake 创建补丁是更好的解决方案？
