Question

您好，我刚刚安装了cmake 3.6.2（cygwin随附的版本），并且在尝试构建llvm时收到错误消息，并说构建失败是因为cc无法找到输入文件。我已经看到很多关于类似问题的帖子，但是在这种情况下，cc是正确的-输入文件实际上不存在，正如我通过检查目录CMakeTmp确认的那样。我在cmake安装目录树中没有任何空格，这通常是问题所在。因此，cmake看起来像是在某个地方搞砸了。有什么想法吗？

因此，我从cmake网站安装了cmake，并且运行正常，因此肯定看起来像cygwin cmake的问题。如果可以的话，我会将此错误报告给cygwin

cmake错误：cc失败，因为没有输入文件
