Linking error: DSO missing from command line

Question

I am rather new to Linux (using Ubuntu 14.04 LTS 64bit), coming from Windows, and am attempting to port over an existing CUDA project of mine.

When linking via

Answer 1

Your linker need X11 library,You need to specify -lX11 to linker

Try

/usr/local/cuda/bin/nvcc -arch=compute_30 -code=sm_30,compute_30 -o Main.o Display.o FileUtil.o Timer.o NeuralNetwork.o -L/usr/lib -L/usr/local/lib -L/usr/lib/x86_64-linux-gnu -L/usr/local/cuda/lib64 -lGLEW -lglfw3 -lGL -lGLU -lcuda -lcudart -lX11

Answer 2

Use the following commands to fix the issue:

FLAGS=-lX11 ./configure --prefix=/usr --disable-static
make
make install

Answer 3

Hopefully this will be of help to those, like me, who are new to Linux and don't find anything related to Linux to be particularly obvious.

As noted by talonmies, I am not able to link indirectly and as such need to specify any additional libraries required by the libraries I am using. That is to say, if I link library A, which requires libraries B and C, I need to link all three libraries for the program to link correctly.

To find what other libraries were needed I used the pkg-config command, for which I found a guide here. Running pkg-config --print-requires --print-requires-private glfw3 gave the following output, which is the list of packages required by glfw3.

x11
xrandr
xi
xxf86vm
gl

I was then able to find what libraries I needed to include by running pkg-config --libs, followed by the name of the library. For example, pkg-config --libs x11 yielded -lX11.

Note: you can pass multiple items to pkg-config as input, so running

pkg-config --libs $(pkg-config --print-requires --print-requires-private glfw3)

will print out all the additional libraries you need to link (-lX11 -lXrandr -lXi -lXxf86vm -lGL).

My program now links successfully, I hope this helpful to anyone with a similar problem.

Answer 4

Try to add -pthread at the end of the library list (command line) in the Makefile.

It worked for me.
