Today's Topics: 1. Score-P wrapping of HPX - missing Symbols (Leon Seifert) ---------------------------------------------------------------------- Message: 1 Date: Fri, 6 Nov 2020 19:52:15 +0100 From: Leon Seifert <leon_friedrich.seif...@tu-dresden.de> Subject: [hpx-devel] Score-P wrapping of HPX - missing Symbols To: <hpx-devel@stellar-group.org> Message-ID: <77dac98d-8e6c-c8a9-cc69-f11872cf8...@tu-dresden.de> Content-Type: text/plain; charset="utf-8" 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: leon@DESKTOP-0GMJBKS:/ ... /cse_ma_scorep_hpx/hpx_libwrap$ make check V=1 g++ -o symbol_check symbol_check.cc -DHPX_APPLICATION_EXPORTS -DHPX_DISABLE_ASSERTS -DBOOST_DISABLE_ASSERTS -DHPX_DISABLE_ASSERTS -DBOOST_DISABLE_ASSERTS -std=c++14 -I/opt/hpx/include -L/opt/hpx/lib /opt/hpx/lib/libhpx.so.1.6.0 /opt/hpx/lib/libhpx_core.so -lboost_system -ltcmalloc_minimal -lhwloc -lboost_filesystem /opt/hpx/lib/libhpx_parallelism.so -lboost_program_options /opt/hpx/lib/libhpx_wrap.a -Wl,-wrap=main /opt/hpx/lib/libhpx_init.a -lpthread -latomic -ldl -lrt /usr/bin/ld: /opt/hpx/lib/libhpx.so.1.6.0: undefined reference to symbol '_ZN5boost15program_options19options_description21m_default_line_lengthE' /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/libboost_program_options.so: error adding symbols: DSO missing from command line collect2: error: ld returned 1 exit status ?
