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

/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

I encounter the following error:

/usr/bin/ld: /usr/local/lib/libglfw3.a(x11_clipboard.c.o): undefined reference to  symbol 'XConvertSelection'
//usr/lib/x86_64-linux-gnu/libX11.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
make: *** [CUDANN] Error 1

The answer seems closely related to the solutions in this post (Strange linking error: DSO missing from command line), though given my inexperience with Linux I was unable to adapt them to my own problem.

Any ideas on what the problem could be?

Here is the full output during compilation: https://gist.github.com/wbolden/857eddd11e4dcb915c02

And here is my attempt at a Makefile: https://gist.github.com/wbolden/135033daae04ed0d8cf3

  • The linker is telling you exactly what the problem is, and the answer you linked to tells you exactly what to do to fix it. You are clearly running on a platform that disallows indirect linking. Add the library dependencies for the required additional libraries (hint libX11 is shown right in the linker error message). I am removing the CUDA tag from this question, it has nothing to do with CUDA or CUDA programming. – talonmies Jul 28 '14 at 06:29

    As I said, I am rather new to Linux (I've only been working with it for a few days), so what might be clear to someone with even moderate experience is not all that clear to me. Using ldd I get the following https://gist.github.com/WilliamHBolden/51a8721b4f8d89df2cef though I don't understand what to do with it. I tried adding -L/usr/x86_64-linux-gnu and -L/lib64 but that did not change the error. – Will Bolden Jul 28 '14 at 06:55

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.

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

  • I tried doing this earlier in the day and it unfortunately did not resolve my problem. Here is the new error I got https://gist.github.com/WilliamHBolden/225d2064f844d33d958f – Will Bolden Jul 28 '14 at 06:59
  • @will bolden: this answer does solve your problem. Adding the x11 library eliminated the dso error. Now you have unsatisfied dependencies. Add those. – talonmies Jul 28 '14 at 15:51

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

It worked for me.

Use the following commands to fix the issue:

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

    Would you care to add some more reasoning, what is the error and how this fixes it? – hB0 Feb 20 '17 at 21:26
