compilation problem

hello
I'm trying to compile your project on Ubuntu 18.04 and I have this compilation error:

Scanning dependencies of target guided_filter_image
[ 93%] Building CXX object examples/CMakeFiles/guided_filter_image.dir/guidedFilter_image.cpp.o

I'm using opencv 3.2
any hints welcomed

found it :
// Copy data to device
rgb.write (cl_algo::GF::SeparateRGB::Memory::D_IN, const_cast<uchar *>(image.datastart));
works
sorry for the noise

Hi @lulu1315 , did you manage to get this compiled and running?

I am getting the following error:

Error when accessing kernel file: ios_base::failbit set: iostream stream error (d:\testing\guidedfilter-master\external\clutils\clutils-master\src\clutils.cpp:224)

Did you have this problem?

Thanks!

hello antithing
sorry i didn't have this problem.
as of guided filtering i'm using gmic (https://gmic.eu/) which has an implementation of it.
see this discussion https://discuss.pixls.us/t/guided-filter-in-gmic/11579
