windows环境下g++无输出的解决方案

问题

powershell 复制代码

PS D:\work_console\exercises> g++ test.cpp -o test.exe

无任何输出

重装、重新配置环境变量无任何效果

添加-v参数后信息为

powershell 复制代码

test.cpp -o test.exe -v

解决方法

powershell里面弹不出来一个报错信息，cmd才可以

从cmd窗口执行c++能够看到

编译器前端组件cc1.exe/cc1plus.exe在运行时加载了错误版本的libwinpthread-1.dll动态链接库。clock_gettime64是近期在mingw-w64运行时库中新引入的API函数。

解决方法1：

直接从C:\msys64\ucrt64\bin中复制libwinpthread-1.dll到工程目录下，然后该工程就可以编译了

解决方法2：

直接从C:\msys64\ucrt64\bin中复制libwinpthread-1.dll到C:\Windows\System32中，则全局的工程都可以编译

github代理问题

OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443

设置代理端口

windows打开设置，代理服务器，查看使用的端口，一般是7890或10809，然后设置端口即可

git config --global http.https://github.com.proxy http://127.0.0.1:7890

git config --global https.https://github.com.proxy https://127.0.0.1:7890
