makefile host_support是啥

Makefile是Unix、Linux及类Unix系统中用于自动化编译和链接程序的脚本文件。它定义了一系列的规则来指示编译器如何编译和链接源代码文件,生成可执行文件或者库文件。Makefile通常包含了一系列的规则和命令,这些规则定义了哪些文件需要被编译,依赖关系是什么,以及如何链接这些文件生成目标文件。
关于`host_support`,这通常是一个Makefile中的变量或者目标(target)。其具体含义取决于Makefile中对它的定义。在很多开源项目中,`host_support`可能是指用来检测和安装适用于宿主机(也就是你正在上面编译软件的机器)的依赖库和工具的目标。这个目标可能包含了一系列的检查步骤,确认宿主机的环境满足软件运行的条件,如果有必要的话,它还可能下载并安装缺少的依赖。
例如,在某些项目中,你可以看到类似这样的Makefile规则:
```makefile
host_support:
./configure --host=$(HOST)
make
```
在这个例子中,`host_support`可能会检查宿主机的环境,并运行`configure`脚本来配置软件的编译选项,然后编译和安装适用于宿主机的软件。

看起来你在运行QCPE配置验证时遇到了一个错误。错误信息显示找不到dotnet可执行文件。这通常意味着你需要安装.NET Core Runtime并将其添加到系统的路径中。
请确保你已正确安装了.NET Core Runtime,并将其添加到环境变量中。你可以使用以下命令检查是否安装了.NET Core Runtime:
```
dotnet --version
```
如果返回版本号,则说明已正确安装。否则,请按照以下步骤安装:
1. 访问 [Microsoft官方网站](https://dotnet.microsoft.com/download/dotnet) ,下载并安装.NET Core Runtime。
2. 安装完成后,打开终端并重新启动您的操作系统,以便更新环境变量。
3. 再次运行QCPE配置验证命令,应该可以成功执行。
如果问题仍然存在,请联系 CDMATech 的技术支持以获取进一步的帮助。

这是一个CMake的错误,它提示找不到C++编译器。建议你检查一下你的系统中是否安装了C++编译器,并确认它的路径是否正确。同时,你也可以通过设置环境变量CXX或者CMake缓存条目CMAKE_CXX_COMPILER来告诉CMake编译器的路径或者编译器名称。另外,CMakeLists.txt文件中还缺少cmake_minimum_required命令,你需要在文件的开头添加这个命令,以指定CMake的最低版本要求。
