From the log messages you posted, it seems that you haven't configured your Dev-C++ project properly to link against glfw
:
g++.exe -D__DEBUG__ main.o -o Projekt2.exe -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/lib32" -L"C:/Program Files (x86)/Dev-Cpp/MinGW64/x86_64-w64-mingw32/lib32" -static-libgcc glew-1.10.0/lib/Release/Win32/glew32.lib -m32 -g3
The glfw
library is missing, that is why you're getting an undefined reference to its functions. You should set up it as you did with glew32
.
Also, the link to What is an undefined reference/unresolved external symbol error and how do I fix it?, provided in the comments to your question, is worth the read.
