无法为 clang 指定额外的链接文件

Question

I've successfully compiled my main.cpp with clang, specifying additional include path via the command line options as follows: clang++ -I ./Dependencies/GLFW/include/ -S .\\main.cpp .

However, when I try to link it by specifying the additional link library by the following command: clang++ -L ./Dependencies/GLFW/lib/glfw3.lib .\\main.s it gives me a linker error main-8b7c4e.o : error LNK2019: unresolved external symbol glfwInit referenced in function main .

Any suggestions on what might be wrong? I'm sure that the relative path specified is correct, since the compile command gave me no issues.

main.cpp

#include <iostream>
#include <GLFW/glfw3.h>

int main() {
  glfwInit();
  std::cout << "Hello world" << std::endl;

  return 0;
}

Answer 1

-L is for specifying folders to search for libraries in. The compiler ignores directories that don't exist.

Your command line should be:

clang++ ./Dependencies/GLFW/lib/glfw3.lib .\main.s

Please find below link for more detail about glfw header inclusion.
