I want to instrument my UPC program with PAPI APIs to get information on hardware counters during the execution of UPC program.
But i keep getting linking errors for eg, "undefined reference to PAPI_read"
undefined reference to PAPI_library_init
etc
The command I'm giving is
upcc -L/full/path/to/libpapi.a -o upcMatrxMultplction upcMatrxMultplction.o
Any suggestions ?
Does PAPI support UPC compiler ?
-L provides a directory, not a think to link with. you should either provide the /full/path/to/libpapi.a as a link argument (along with *.o), or else use "-L/full/path/to -lpapi". the latter is a bit more conventional.
also, linking can be order-dependent, so I prefer to list all to-link objects first and end the line with -o whatever.
