我们可以在 ubuntu 20.04 上安装旧版本的 gcc 和 g++

Question

我目前有 Ubuntu 19.10 和 gcc 9.1.2

\n\n

我想为 CUDA 8 安装以前版本的 gcc（在本例中为 gcc 5）。但我收到此错误：

\n\n

(base) \xe2\x9e\x9c ~ sudo apt-get install gcc-5 g++-5                                 \nReading package lists... Done\nBuilding dependency tree       \nReading state information... Done\nPackage g++-5 is not available, but is referred to by another package.\nThis may mean that the package is missing, has been obsoleted, or\nis only available from another source\nHowever the following packages replace it:\n  gcc-7-test-results gcc-8-test-results:i386 gcc-7-test-results:i386\n  gcc-8-test-results gcc-9-test-results:i386 gcc-9-test-results\n\nPackage gcc-5 is not available, but is referred to by another package.\nThis may mean that the package is missing, has been obsoleted, or\nis only available from another source\n\nE: Package 'gcc-5' has no installation candidate\nE: Package 'g++-5' has no installation candidate\n

我们可以在 Ubuntu 20.04 中安装它吗？
