ArrayFire compilation and dependence on libGL

[pushknly1]

Hi,

I have downloaded a copy of ArrayFire for evaluation and was trying to compile the examples. The compilation failed for the helloworld example. This is the error I get,

cc -m64 -Wall -Werror -I/N/u/pratnali/BigRed2/Software/arrayfire-2.0/include -pthread -O2 -DNDEBUG -DAFCL -lrt -Wl,--no-as-needed -L/N/u/pratnali/BigRed2/Software/arrayfire-2.0/lib64 -lpthread -lstdc++ -lm -Wl,-rpath,/N/u/pratnali/BigRed2/Software/arrayfire-2.0/lib64,-rpath,/N/u/pratnali/BigRed2/Software/arrayfire-2.0/lib64 -lafcl helloworld.cpp -o helloworld_ocl

/usr/lib64/libGL.so.1: undefined reference to `xcb_glx_set_client_info_2arb'
collect2: error: ld returned 1 exit status
make: *** [helloworld_ocl] Error 1

The gcc version on the system is 4.8.1.

Could you please suggest a solution for this problem?

Hi,

Can you tell us the distribution you are using ?

Hi,

It is Cray Linux Environment 4.1.UP01. The system is basically a Cluster and the compilation was tried on a single node. A google search suggested that the issue might be related to MESA driver, but I do not have admin privileges on the system and cannot change it.

Hi Puskhar,

Can you see if you can find libxcb.so or libxcb-glx.so on your system ?

[pushknly1]

Hi,

Yes I have got both libxcb.so and libscb-glx.so.

Can you open common.mk in arrayfire/examples and add "LD_FLAGS += -lGL -lxcb -lxcb-glx" just above " cuda:" line and let me know how it goes.

Hi,

Unfortunately I am getting the same error with the change.

Hi,

If you are not going to use visualization we can try to get you a version of ArrayFire without graphics. This way you will not have libGL dependencies. This will however take a little bit of time from our side.

You can email support@accelereyes.com with the link to the forum so we can create a ticket and get back to you once we have the required version.

Hi Pavan,

Thanks a lot. We don't need visualization. I will go ahead and send a request to the mentioned email.
