Fail to load ELF for exe #8

Closed zhuguoliang closed 9 years ago

zhuguoliang commented 9 years ago

I am running benchmark program GemsFDTD_base.gcc in spec06

I tried the following command : hotpatcher -l ./Release/libhotpatchtest.so -s mysym -vvv 15912 (15912 is the pid of GemsFDTD_base.gcc )

I got the following result: Options Given: Verbose Level: 2 Process PID: 15912 Symbol name: mysym Library name: ./Release/libhotpatchtest.so Dry run: false [exe_load_headers:490] Entry point 0x3408048db0 [exe_load_headers:510] Error in loading section headers [exe_load_symbols:539] Unable to load Elf details for /proc/15912/exe [hotpatch_create:197] Unable to find any symbols in exe. [hotpatch_inject_library:594] No malloc/dlopen found.

Sorry, just saw this. What operating system are you running here ?
