That may be the case: edd@max:~$ apt-cache search lib|grep OpenCL ocl-icd-dbg - Debug symbols for the generic OpenCL ICD Loader ocl-icd-libopencl1 - Generic OpenCL ICD Loader ocl-icd-opencl-dev - OpenCL development files nvidia-libopencl1-304 - NVIDIA OpenCL Driver and ICD Loader library nvidia-libopencl1-304-updates - NVIDIA OpenCL Driver and ICD Loader library nvidia-libopencl1-331 - NVIDIA OpenCL Driver and ICD Loader library nvidia-libopencl1-331-updates - NVIDIA OpenCL Driver and ICD Loader library nvidia-opencl-dev - NVIDIA OpenCL development files python-pyopencl - Python module to access OpenCL parallel computation API python-pyopencl-dbg - Python module to access OpenCL API (debug extensions) python-pyopencl-doc - module to access OpenCL parallel computation API (documentation) python3-pyopencl - Python 3 module to access OpenCL parallel computation API python3-pyopencl-dbg - Python 3 module to access OpenCL API (debug extensions) beignet - Intel OpenCL library beignet-dev - Intel OpenCL library libclc-dev - OpenCL C language implementation - development files libclc-ptx - OpenCL C language implementation - ptx support libclc-r600 - OpenCL C language implementation - r600 support libopencv-ocl2.4 - computer vision OpenCL support library libopentk-cil-dev - Open Toolkit wrapper for OpenGL, OpenAL and OpenCL - Dev files libopentk1.0-cil - Open Toolkit wrapper for OpenGL, OpenAL and OpenCL - Assemblies libviennacl-dev - Scientific computing library written in C++ based on OpenCL monodoc-opentk-manual - Open Toolkit wrapper for OpenGL, OpenAL and OpenCL - Docs edd@max:~$ This shows that eg the Python OpenCL bindings come with a full debug library, something Debian frequently does for normal shared libraries (ie we create r-base-core-dbg for debug support R, but eg I never bothered to do the same for r-mathlib). So while no exhaustive "proof" of any kind, based on this JJ's talk of "a rub" may be on to something.
