同时安装32位和64位版本的libgoogle-perftools dev。

Question

我是在Debian伸展和需要google-完善工具来分析我的一些程序。我的机器是64位；我为64位和32位构建程序(使用gcc -m32)。我想能同时分析两种情况。我已经安装了libgoogle-perftools-dev。当我现在尝试添加x86变量时，apt希望删除x64变量(参见下面)。这两种变体可以互相安装吗？

不同的google-perftools包在他们的控制档案中没有必要的Multi-Arch:声明，所以不可能并行安装i386和amd64包(没有强制--安装它们，这将导致apt抱怨很多，并阻止安装或升级任何其他软件包)。

您可能需要提交一个bug，请求启用此功能。为此，运行reportbug libgoogle-perftools-dev并按照提示操作。

有关在64位系统上运行32位程序的其他方法，请参见如何在64位Debian/Ubuntu上运行32位程序？ (如吉尔斯所建议的)。
