构建失败的GEM5，当文件存在时找不到错误文件

Question

当我尝试在WSL2 Ubuntu_20.04上构建GEM5时，它失败了。

我在此 SCONS构建/x86/gem5.opt -j9

构建失败了：

但是当我检查错误文件IE build> build/libelf/libelf/andation-format 时，它存在于事实。

root@REALME-NUT:~/gem5# ls ./build/libelf | grep native
native-elf-format
native-elf-format.h

也许有人有相同或相似的问题？

如果您能提供帮助，我将不胜感激。

:)

Answer 1

我对Gem5的SCONS的使用不太熟悉。

也就是说，我认为他们使用的是AutoConfigure逻辑，在这种情况下，应该有一个名为Config.log的文件，该文件可能会有更多（有用的）有关失败的信息。

Answer 2

我是Gem5的新手。但是在构建Gem5时，

python3` scons` build/x86/gem5.opt -j 8

此命令更好地照顾错误和依赖关系

Answer 3

很好，我发现了关键问题。我在窗口上下载了GEM5拉链，然后将其CP CP下载到WSL系统。也许下载Windows将文件送至DOS格式，当我从一开始就使用VMware重新启动时，它可以正常工作。
thx所有答案。
