FlappingBird make error

I installed curl, xorg-dev and libglu1-mesa-dev and then make but it failed. Here is output: build/main.o: In function main': main.cpp:(.text+0x40): undefined reference tosge::Game::run()' build/Pipe.o: In function Pipe::Pipe(sge::Vector2 const&, sge::Sprite const*, sge::Sprite const*)': Pipe.cpp:(.text+0x43): undefined reference tosge::Rectangle::Rectangle(float, float, float, float)' ..................................................... collect2: error: ld returned 1 exit status make: *** [flappingbird] Error 1

Did you remember to use git clone --recurse-submodules https://github.com/C0deH4cker/FlappingBird.git when cloning? Or at least git submodule update --init --recursive after cloning?

I used git clone --recurse-submodules https://github.com/C0deH4cker/FlappingBird to clone before. But it still had error. It seems to be a problem with libsge.a lib. I built it on Ubuntu, is it different ??

Hmm, it should be fine. Try deleting the whole repo, cloning it again, and cd into FlappingBird/SimpleGameEngine before running make. If it works, then try make in FlappingBird. If you still get errors, paste them here.

Did libsge.a even build successfully? Can you show the contents of FlappingBird/SimpleGameEngine/build please?

Okay, I think that I may know what the issue is. In that folder, run ar -t libsge.a and look for an entry named __.symdef. If that doesn't exist, run ranlib libsge.a and then make in FlappingBird.

Mar 09 '14 07:03 C0deH4cker

I ran ranlib libsge.a but that lib still didn't have any entry named __.symdef. So, make failed too

Mar 09 '14 19:03 khanhnb

That's really odd... What's the output of running nm Window.o?

Okay, run make clean again in all dirs (FlappingBird, SimpleGameEngine, glfw). Delete the Makefile from glfw/. Then, make the following change:

On line 73 in the Makefile of SimpleGameEngine, change the capital S in the flags to ar to a lowercase s. So,

$(AR) -cruS $(LIB) $(ARCHIVED)

becomes

$(AR) -crus $(LIB) $(ARCHIVED)

It appears that the static library libsge.a has no object file index, which is why the linker cannot find symbols. Running ranlib on the archive should have added the object file index, but this change will make it happen as the archive is created.

@khanhnb so have you solved the problem already? Faced the same issue and came across this thread. No luck here stuck with the same problem @C0deH4cker
