如何获得合适的 C++ 来编译 CMAKE

Question

我在 Winodws7 64bit 上使用 MinGW64+msys

现在我正在尝试构建 CMAKE，但我做不到。

当我键入 ./configure 时，很快就发生了错误。 .

---------------------------------------------
CMake 3.2.3, Copyright 2000-2015 Kitware, Inc.
Found GNU toolchain
C compiler on this system is: gcc
---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.
See cmake_bootstrap.log for compilers attempted.

我还在 Bootstrap.cmk/cmake_bootstrap.log 中找到错误消息，如下所示。

[日志文件中的第一条消息]

[日志文件中的第二条消息]

他们说 cwchar 和 iostream.h 不存在，尽管我有它们并将它们的路径设置为环境变量。

第一条消息说我的C++编译器不合适。我通过 mingw-get.exe.

安装了它

有谁知道，我怎样才能获得合适的 C++ 编译器？

Answer 1

您混用了两个编译器。我建议：删除旧的并安装 .
