linux - CMake 3.15.5 引导程序因 g++ 9.3.0 而失败
问题描述
我正在尝试在 20.04 xubuntu 机器上构建 CMake 3.15.5(但我也尝试了 18.04 和 20.10,结果相同)。
错误如下:

Error when bootstrapping CMake:
Problem while running initial CMake
我绝对确定 g++ 9.3.0 支持 C++11,那么问题出在哪里?
(编辑:添加 CMakeError.log)
这是CMakeError.log

我无法弄清楚 wath 是错的。我认为这可能是时钟偏差问题,但我也在虚拟机之外尝试了相同的结果。
我还尝试手动编译和链接,没有任何错误或警告。
/usr/bin/g++ -O2 -std=gnu++17 -o cm_cxx_make_unique.cxx.o -c /home/max/Lavori/nova/srcs/repo/dep-startup/buildroot-output/buildroot-2020.02.1/output/build/host-cmake-3.15.5/Source/Checks/cm_cxx_make_unique.cxx

我还尝试无错误地运行二进制文件。所以更“我不知道出了什么问题”
解决方案
使用 Linux 虚拟机 (VMware) 和将源放在共享文件夹中时出现相同的错误。将源移动到用户文件夹时全部配置成功。
