无法使用命令行链接库错误LNK2019

如何解决无法使用命令行链接库错误LNK2019

我正在尝试使用cl.exe编译器附带的GLFW和GLEW手动编译项目。我在链接.lib文件时遇到麻烦。链接器似乎忽略了/ LIBPATH。我添加了/ VERBOSE：LIB以查看链接程序正在搜索什么。

命令

cl src/main.cpp /I include /link /LIBPATH:C:\Users\user\Desktop\C++\VSCode1\lib /VERBOSE:LIB

输出

/out:main.exe
/LIBPATH:C:\Users\yuryi\Desktop\C++\VSCode1\lib
/VERBOSE:LIB
main.obj

... and a lot of error LNK2019 unresolved external symbol

解决方法

通过在命令中添加glfw3.lib和glew32.lib修复了该问题

cl main.cpp glfw3.lib glew32.lib /I include /link /LIBPATH:C:\Users\user\Desktop\C++\VSCode
