Intel Pin with C++14

Question

The Questions

I have a few questions surrounding usage of Intel Pin with C++14 or other C++ verions.

• There are rarely any problems compiling code from older C++ with newer versions, but since Intel Pin is manipulates instruction level, is there any undesirable side effects that might come if I compile it with C++11 or C++14?
• If it's ok to compile with C++11 or C++14, how do I make a rule to enable a newer version of C++ for my tool only?
• How do I set GCC/G++ default C++ version to latest, if possible, and what should I keep in mind when doing so?

Situation

I'm building a dynamic call graph pin tool. To make it understandable, I'm computing the depth of the call stack. For safety, I decided to wrap the excerpt of code that increments or decrements the depth with a std::mutex . This has gotten me to the problem that std::mutex is available only since C++11, which is not Intel Pin default in my machine.

$ g++ -v
[...]
gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.2)

Compile command:

$ make obj-intel64/callgraph.so
[...]
error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
#error This file requires compiler and library support
[...]

EDIT

I managed to make a build rule that defines version to C++11, but it breaks. The command sent to g++ through make was

g++ -DBIGARRAY_MULTIPLIER=1 -Wall -Werror -Wno-unknown-pragmas -D__PIN__=1
-DPIN_CRT=1 -fno-stack-protector -fno-exceptions -funwind-tables

-fomit-frame-pointer -fno-strict-aliasing  -std=c++11 
-c -o obj-intel64/callgraph.o callgraph.cpp

This doesn't compile. Instead, it'll fall into a huge error log inside STL headers. It appears that Pin comes along with it's own subset of STL, that conflicts with C++11 and C++14. I've uploaded a paste of the g++ output. It filled 2331 lines, but I've noticed that strange thing in the folders it visits. STL libraries are included from 2 different directories:

• /usr/include/c++/5/
• /home/gabriel/Downloads/pin-3.0-76991-gcc-linux/extras/stlport/include/

Solving errors one-by-one is unfeasible, deleting pin stl port probably is an even worse idea. If it's possible to use Pin with newer C++, I'd say simple std=c++1y is not the way.

Answer 1

From the compiler options used to compile the pin tool, I presume you are using the latest version of Pin, namely 3.0. According to Intel , the CRT that ships with the framework doesn't support C++11 and later versions of the language. In particular, you will not be able to use any of the APIs supported in C++11 including std::mutex . If it's critical for you to use C++11 APIs then you should use the previous version of Pin, namely 2.14, which doesn't ship with a CRT and uses the CRT of your compiler.

However, if all you want is a mutex, you can use the OS-portable mutex that ships with Pin 3.0. For more information, refer to the documentation .

When using Pin 3.0 you are not allowed to use any header file or object file of your compiler (those from /usr/include/c++/5/ ). You can only use PinCRT and few system header files.
