Hard-coded relative path in test/tuner.cc

[OursDesCavernes]

Hello,

I'm writing a Gentoo package for CLTune: sci-libs/cltune

The Gentoo package manager (Portage) can perform unit tests automatically after build and before installation.
A hard-coded relative path at test/tuner.cc#L46 breaks the tests as it assumes that the binary is run from a subdirectory of the source root.

An option would be to pass the source or sample base path by argument and fall back to ../samples/ if omitted.

What do you think ?

You are right, that is an issue. Luckily the tuner also accepts kernels as strings instead of loading them from file: I changed this in the latest version of the development branch. It changes test coverage slightly, but passing arguments to the Catch framework is apparently also not so trivial. I believe this is the best solution for now.
