Good afternoon,
I could not make work the examples included in ViennaCL yet. However, I
compared the result of ldd on one of the ViennaCL examples and clinfo. The
number of linked libraries is significantly different and I wonder if any
of them should be also linked for the ViennaCL example and how I can add
them to the compilation.
The output of ldd is below.
Thanks in advance.
Best regards,
Sadra
