我在 Debian Stretch 上并且需要谷歌性能工具来分析我的一些程序。我的机器是64位的；我为 64 位和 32 位构建了程序（使用gcc -m32）。我希望能够对两者进行分析。我已经libgoogle-perftools-dev安装了。当我现在尝试添加 x86 变体时，apt想要删除 x64 变体（见下文）。是否可以将这两个变体并排安装？

各种包中google-perftools没有必要的声明Multi-Arch:他们的控制文件，所以不，不可能并行安装i386和amd64软件包（除非强制安装它们，这会导致apt很多抱怨并阻止安装或升级任何其他软件包）。
您可能想要提交一个错误，要求启用此功能。为此，请运行reportbug libgoogle-perftools-dev并按照提示操作。
