CUDPP 1.1

[susan]

Hi everyone,
I have built the CUDPP 1.1 on CUDA 2.2 on linux ubuntu successfully,
but I still got some problems in building the test program,


nst@amt63:~/cudpp_1.1/apps/simpleCUDPP$ make
/usr/bin/ld.real: cannot find -lGL
collect2: ld returned 1 exit status
make: *** [../../bin/linux/release/simpleCUDPP] Error 1


Do anyone knows how to solve this problem?

Thank you in advance

I don't know where your libraries are on Ubuntu, but this is an error in linking against the GL library, probably libGL.so or libGL.a. Make sure these are installed? I bet they are and it's just a matter of editing the makefile with a -L flag for the path where they are.

Hi again,

My libraries are on NVIDIA_CUDA_SDK/lib

Thank you for your help

[John Owens]

Your system libraries, like libGL, are located elsewhere (in /usr/lib or something like that)

Hello,
how do I link it? like this

nst@amt63:~/cudpp_1.1/apps/cudpp_testrig$ make -L/usr/lib/Glib -lGL

many thanks

Go into common/common.mk and add -L/usr/lib/Glib to the front of the LIB variable:

LIB       := -L/usr/lib/Glib -L$(CUDA_INSTALL_PATH)/lib -L$(LIBDIR) -L$(COMMONDIR)/lib -lcuda -lcudart ${OPENGLLIB} ${LIB}

(assuming that /usr/lib/Glib/libGL.something is present and the right library)

Then just "make" as usual.

This is a hack that will probably work, but the common makefile already has opengl linkage, it just must be looking at the wrong place for Susan's system.  The sad thing is that simpleCUDPP should not need OpenGL, so we should not be linking against it -- in other words this is a makefile bug.
