问题
I've been attempting to test out GLFW with C++ for quite a while and am having constant linker issues. I am fairly new to C++, although I have experience in Java and C#, working directly with the compiler is fairly new to me. Here's my setup information.
IDE: Qt Creator
OS: Windows 7 64-bit
Compiler: MinGW32 4.8.1
01:23:26: Starting: "C:\MinGW\bin\mingw32-make.exe"
C:/MinGW/bin/mingw32-make -f Makefile.Debug
mingw32-make[1]: Entering directory 'A:/workspace_cpp/Test-Debug'
g++ -Wl,-subsystem,console -mthreads -o debug\Test.exe debug/main.o -lglfw3 -lopengl32

c:/mingw/bin/../lib/gcc/mingw32/4.8.1/../../../../mingw32/bin/ld.exe: final link failed: Invalid operation
collect2.exe: error: ld returned 1 exit status
The code I'm testing is the code on the GLFW Documentation Page, I'm using my own build of GLFW, and have already tried this and several other potential solutions. I have tried using the prebuilt GLFW mingw libraries but I couldn't get them to work.
回答1:
The solution as posted by enhzflep was to include to gdi32 library when compiling, making all the necessary linkers -lglfw3 -lgdi32 -lopengl32, as the missing methods, CreateDCW, GetDeviceCaps and DeleteDC are all inside of libgdi32.a in the MinGW lib folder C:\MinGW\lib\libgdi32.a in this case.
