Environment Configuration

Note that this is just the environment we are currently working under, and it’s at your own risk to adopt the other environments.

• OS：Ubuntu 16.04.1 Desktop
• Eclipse： eclipse-cpp-2018-12-R-linux-gtk-x86_64
• Gem5 Commit ID：c428c220fd351626e2ee0005dda696940261793b
• OpenJDK: 1.8.0_191

Steps to Work

1. Build gem5.debug

   git clone https://github.com/gem5/gem5
   cd gem5
   scons build/X86/gem5.debug -j$(cat /proc/cpuinfo | grep "processor" | wc -l)
   cd util/term
   make && sudo make install
   cd ../../..
   

2. Install JRE

   sudo apt install default-jre
   

3. Setup eclipse

   wget http://ftp.yz.yamagata-u.ac.jp/pub/eclipse/technology/epp/downloads/release/2018-12/R/eclipse-cpp-2018-12-R-linux-gtk-x86_64.tar.gz
   tar -xvzf eclipse-cpp-2018-12-R-linux-gtk-x86_64.tar.gz
   

4. Config eclipse

   1. Open eclipse

      cd eclipse
      ./eclipse
      

   2. Import gem5.debug as the C/C++ executable file

      Menu -> File -> Import -> C/C++ folder -> C/C++ Executable -> Select gem5.debug

      eg. at gem5/build/X86/gem5.debug

      
      

   3. Create a lauch configuration

      Just Leave every thing AS IT IS.
      

5. Debug configurations
   1. Set arguments for gem5.debug to bootup gem5 in the way you expected.
      
   2. Set the variable M5_PATH to point out the location of your binaries if you are to use gem5 FS mode.
      
   3. Tell Eclipse where to lookup the source.
      
      eg. at gem5/build/X86
6. Just be ready for THE ENDLESS NIGHTMARE gem5 will bring!
