[Starpu-devel] Linker errors in make while trying to build starpu

[ASD D <ajitsdeshpande@gmail.com>]

Hello,

  I use below configure command to build starpu on a 64 bit system. Trying to the OpenCL version in the NVIDIA driver which I have installed.( --with-opencl-lib-dir=/usr/lib/ -->hoping this would link the shared library /usr/lib/libOpenCL.so

./configure --with-opencl-include-dir=/usr/include/ --with-opencl-lib-dir=/usr/lib/ CFLAGS="-I/home/deshpandea/lpng155/ -I/home/deshpandea/moviSimStarPU/trunk/examples/basic_examples/ -I/home/deshpandea/zlib-1.2.5/" LDFLAGS="-l:/home/deshpandea/lpng155/libpng15.so" LDFLAGS="-l:/home/deshpandea/bin/zlib/lib/libz.so" LDFLAGS="-l:/usr/lib/libOpenCL.so.1.0.0" LDFLAGS="-m32 -l:/home/deshpandea/moviSimStarPU/trunk/moviSim/moviSimDll.so" LDFLAGS="-l:/usr/lib32/libm.a" LDFLAGS="-l:/usr/lib32/libstdc++.so.6.0.14" LDFLAGS="-l:/usr/local/cuda/lib64/libcudart.so" LDFLAGS="-l:/usr/local/cuda/lib64/libcublas.so" --enable-debug --enable-verbose --disable-cuda

 

Configure is OK, but make give errors as :

../src/.libs/libstarpu.so: undefined reference to `clCreateCommandQueue'  

../src/.libs/libstarpu.so: undefined reference to `clEnqueueReadBuffer'

../src/.libs/libstarpu.so: undefined reference to `clCreateProgramWithSource'

../src/.libs/libstarpu.so: undefined reference to `clEnqueueWriteBuffer'

../src/.libs/libstarpu.so: undefined reference to `clReleaseKernel'

../src/.libs/libstarpu.so: undefined reference to `clGetDeviceIDs'

... Many more undefined references to OpenCL

 

These are very basic primitives in opencl which even ver 1.0 spec supports, so I suspect there is something else going wrong here in my build like the OpenCL lib. Not getting linked to starpu build itself? (Although I even explicitly gave the library in the LDFLAGS option to configure above as LDFLAGS="-l:/usr/lib/libOpenCL.so.1.0.0")

 

Can anyone point what I am doing wrong here? What is needed to fix.

thank you.
