Dear HPX Developers,
for my Master Thesis I want to wrap the HPX Library with Score-P, in
order to enable Score-P to trace Applications, which are using HPX.
While doing this I encountered the Problem, that Score-P cannot find any
of the Symbols of HPX. And my Question is, if you have any experience
using Score-P and HPX or any Idea, why I might not be able to find these
Symbols.
A list of the existing Symbols is given by: "nm -D --defined
/opt/hpx/lib/libhpx.so". One of these is: "_ZN3hpx7runtime8finalizeEd".
The problem is that the "make check" of "scorep-libwrap-init" cannot
find any of the 1688 Symbols which should be in my example Code. The
Output for one missing Symbol is below this email. When wrapping other
Libraries, like OpenBLAS, all Symbols are found.
In case you need more information about my HPX build or other factors, I
am happy to send more.
Thank you very much for your work!
Greetings,
Leon Seifert
In the following example all Symbols except "_ZN3hpx7runtime8finalizeEd"
were filtered out:
