我已经从网址 https://bitbucket.org/rmcantin/bayesopt/下载了源尝试构建程序时，我已经下载了适用于Windows的MinGW编译器，错误是:

I have downloaded source from url https://bitbucket.org/rmcantin/bayesopt/ and i have downloaded the MinGW compiler for Windows when I try to build the program the error is:

请帮助我，我在尝试构建贝叶斯优化时也删除了旧的缓存.

Please help me on this I have also deleted the old cache when I try to build the bayes optimization.

推荐答案

您可以先尝试在不使用CMake的情况下编译一个简单的C ++程序.例如.将简单的 main.cpp 存储在用户目录 C:\ Users \< yourname> \ Temp 目录中的某个位置，其中包含以下内容:

You could try to compile a simple C++ program first without CMake. E.g. store a simple main.cpp somewhere in your user directory C:\Users\<yourname>\Temp directory with following content:

int main() 
{
   return 0;
}

现在在 C:\ Users \<您的名字> \ Temp 目录中打开CMD窗口并运行:

Now open CMD window in your C:\Users\<yourname>\Temp directory and run:

C:\MinGW\bin\gcc.exe main.cpp -o testprog

如果出现错误弹出窗口，说明缺少的.dll，请在CMD窗口中运行以下命令，然后尝试再次编译:

If an error popup appears that is saying something about a missing .dll, run following command in your CMD window and try to compile again:

set PATH=%PATH%;C:\MinGW\bin

如果必须运行最后一条命令，请永久添加C:\ MinGW \ bin路径.毕竟，应该可以将MinGW作为编译器运行 CMake .

If you had to run the last command, add the C:\MinGW\bin path permanently. After all it should be possible to run CMake with MinGW as compiler.
