I have declared an

test.cpp:

volatile int var;

and attempt to use this via extern in my pintool. However each time dlopen fails to find the variable. I have tried compiling test.cpp with -rdynamic.

Is there any way for the program and the pin tool to have some shared memory to communicate?

  • You want your instrumentation C functions to use the value of `var` directly? I don't think they normally get linked together; the PIN tool just attaches to the other process like a debugger, doesn't it? (I haven't used PIN directly, just SDE occasionally.) – Peter Cordes Mar 03 '19 at 21:56
