I just installed GLFW3 on Ubuntu and I'm testing the example code from the documentation (http://www.glfw.org/documentation.html) and I got those errors.
I tried multiples thing like adding -ldl, but nothing seems to work.
Here is the error log (GCC):

Order of libraries matter. If library A depends on library B, then A must come before B on the command line.
In your case, since the glfw3 library depends on the dl library, you must switch order so that glfw3 comes before dl on the command line.
You also must link with the X11 library.
So the full command line should look something like
g++ -o bin/Debug/Game obj/Debug/main.o -lglfw3 -ldl -lm -lGL -lGLU -lX11

so i was trying to set up vulkan on vscode in windows.
and i strugle to fix the link errors.
at first i had problems with GLFM
but it looks like i sorted it out, by compiling it with mingw myself.
but now i guess the following link error
undefined reference to `vkEnumerateInstanceExtensionProperties#12'
how should i resolve that issue?
my makefile looks like that at the moment:
DIR1 := external/GLFM/include
DIR2 := external/glm/
DIR3 := external/vulkan/Include
INC=$(DIR1) $(DIR2) $(DIR3)
INC_PARAMS=$(foreach d, $(INC), -I$d)
LDPATHS2 := -Lexternal/GLFM/Lib/ -Lexternal/vulkan/Lib/
LDLIBS = -lglfw3 -lvulkan-1 -lgdi32
VulkanTest: main.cpp
g++ $(CFLAGS) $(INC_PARAMS) $(LDPATHS2) -o VulkanTest main.cpp $(LDLIBS)
EDIT:
i have added the -lgdi32 as that seemed to get rid of all of those
link errors:

I've compiled the OpenSSL library using Mingw32 and MSys with Strawberry Perl.
I used this forum post as a guide, even though it's quite old.
How to build OpenSSL with MinGW in Windows?
Everything went fine, I wanted to compile it as a static library and it worked, but whenever I try to compile the library with my project using g++ I get the following errors, which I have no idea what they mean.

I am taking a computer graphics course using opengl, and for the life of me, I've not been able to compile a single opengl program using the teacher's makefile without doing it on the school's server. I'm not an experience C programmer, so make files are a bit new to me. I've been spoiled by Eclipse compiler always making my build.xml file for me.
I am using cygwin since the teacher's make file is for linux/unix. I have also installed opengl on it via searching under the Graphics category on installation. This is my make file:

Makefile:36: recipe for target 'MyCoolModel' failed
make: *** [MyCoolModel] Error 1
I've been hearing that this sort of problem lies with the linker, although I'm not exactly sure what that means. I am assuming that my header files were recognized, my binaries weren't, or were in the wrong directory.
My teacher's Makefile says that the opengl library files are in a directory called /usr/lib64, but checking my cygwin user directory, it does not exist. I can see the /usr/include folder, though. This could the the problem, but I have no idea how to resolve it. I though that installing opengl on cygwin would take care of this.
Assuming that this is the problem, could anyone help me locate these library files?
I'm working on a modification of the Wolfenstein 3D engine in SDL2 (using Wolf4SDL as a base) and I've run into a problem - when using -static in the linker options, I get a large variety of undefined references to various things. Here's my build log to show what I mean:

This does not happen when linking a normal Wolf4SDL mod (which uses SDL 1.2), and it links correctly if I don't use -static but then won't run without various other DLLs being present (namely libgcc_s_dw2-1.dll and the like). While I can just change PATH to include my MinGW directory, when it comes time to distribute it I can't expect everyone to have MinGW installed, and I want to keep the number of DLLs I'm distributing with my mod to a minimum considering I'm already using SDL_mixer and SDL_image which come with a ton of DLLs already. Anyone have a solution to this?
OK, fixed the problem - I needed to link a variety of Windows libraries, namely Ole32, Oleaut32, Imm32, Winmm and Version. Not sure why this wasn't the case for SDL 1; it wasn't mentioned in the Migration Guide either so I'm not sure where the difference comes from.
For me this meant "use pkg-config --static" since I had compiled a static only version and wanted to use that.
Guess that's just how pkg-config rolls.
Another option (like the OP mentioned) is to either add the libraries you need "out of band" or to modify sdl2.pc so it includes "all the libraries you need" on the Libs: line (not Libs.static: line which probably already has them).
Again, that's how pkg-config rolls :|
I am trying to compile a very simple OpenGL program that uses GLFW3. Despite linking everything I deem necessary, I'm getting a plethora of undefined references.

My linked CMake flags:
-I/usr/local/include -L/usr/local/lib -lglfw3 -lGLU -lGL -lGLEW
Should I be linking anything else?
I figured out the answer myself while writing the question.
I was misled into believing that I was linking everything necessary because of the output of
pkg-config --libs --cflags --print-requires glfw3
which was
-I/usr/local/include -L/usr/local/lib -lglfw3
The --print-requires flag was having no impact at all on the output, which seemed odd. I searched and printed the corresponding .pc file.
sudo find / | grep "glfw3\.pc"
cat /usr/local/lib/pkgconfig/glfw3.pc
There I found this.
Requires.private: x11 xrandr xi xxf86vm gl
Which indicates which libraries are required for static linking. I added their correponding flags to CMake and it worked. My mistake was that I missed the --print-requires-private flag when executing pkg-config.
I hope this helps someone save some time.
