I was having some issues while working with Sniper Multicore Simulator 7.2 with Pin tools 3.11. So I followed the logs and found some ways to clean things up and make it workable. Keeping it here so that in future I might use the same application without any hassles.

1. Download the necessary files
   1. Sniper simulator 7.2
      $ wget http://snipersim.org/download/b83613395338cc0e/packages/sniper-latest.tgz
   2. pin tools
      $ wget https://software.intel.com/sites/landingpage/pintool/downloads/pin-3.11-97998-g7ecce2dac-gcc-linux.tar.gz
2. Then install required Dependencies
   $ sudo dpkg --add-architecture i386
$ sudo apt-get install binutils build-essential curl git libboost-dev libbz2-dev libc6:i386 libncurses5:i386 libsqlite3-dev libstdc++6:i386 python wget zlib1g-dev
3. Now extract sniper file into a directory. I am assuming you will extract it in ~/sniper-7.2 directory.
   $ tar xvzf sniper-latest.tgz
4. Now extract the pintool into another directory. I am assuming you will extract it in ~/pin-3.11-97998-g7ecce2dac-gcc-linux/ directory.
   $ tar xvzf pin-3.11-97998-g7ecce2dac-gcc-linux.tar.gz
5. Make a folder inside the
   $ mkdir -p ~/sniper-7.2/pin_kit
6. Copy the pin tool extracted files to ~/sniper-7.2/pin_kit/ directory
   $ mv ~/pin-3.11-97998-g7ecce2dac-gcc-linux/* ~/sniper-7.2/pin_kit/
7. add PIN_HOME variable to system path by editing ~/.bashrc
export PIN_HOME="~/sniper-7.2/pin_kit"
8. Modify the ~/sniper-7.2/tools/pinversion.py file at Line 12
for filebase in ( 'source/include/pin/pin_version.h', ):
   Remember the comma after the path is important. This is to treat the range as a tuple, if we do not put the comma, then the range would be compared as a array of string instead.
9. Edit the files to put proper namespace before string, cerr and endl
   You can just add using namespace std; on the files that cause error.
   Or you can add std:: before each instance of string, cerr and endl
   These are the files where you need to add using namespace std; after the #include part
   
   • sift/standalone_pin3.0/globals.cc
   • sift/recorder/globals.cc
   • frontend/pin-frontend/globals.cc
   • sift/standalone_pin3.0/globals.h
   • sift/recorder/globals.h
   • frontend/pin-frontend/globals.h
   • sift/standalone_pin3.0/papi.cc
   • sift/recorder/papi.cc
   • sift/recorder/recorder_control.cc
10. Now make sure you are the ~/sniper-7.2 directory by doing
    $ cd ~/sniper-7.2
11. compile the sniper simulator
    $ make -j12
    Here I have used -j12 because of 12 cores in my computer.
12. To test your build, go to one of the test directory
    $ cd ~/sniper-7.2/test/fft
13. run the file
    $ make run
