Compiling NextGenMap from source throws error about not finding opencl on a non-gpu system

[samfux84]

Hi,

I tried to install NextGenMap 0.5.0 on a pure CPU cluster. I was following the installation instructions provided at:

https://github.com/Cibiv/NextGenMap/wiki/Installation

The installation instructions explicitly state:

In order to build NextGenMap only cMake (>=2.8) and g++ are required.

But when following the instructions, the make step crashes with an error message that libOpenCL could not be found:

If only cmake and g++ are required, why is the compiler trying to link against opencl, that is not mentioned as dependency to build NextGenMap ?

Hi, OpenCL is not listed as dependency as NextGenMap comes with the OpenCL libraries included. Without more information I can't comment on why it is not working on your system. What operating system is the cluster running on? And could you please provide the exact commands you used for compiling and a full log? In general, if possible, I would recommend using (bio)conda for installing NextGenMap. But I realise that's not always an option. Thanks, Philipp
