 Since we build off of gem5, all of the dependencies of gem5 are also dependencies of gem5-gpu. It is suggested that before you try to compile gem5-gpu you compile a copy of gem5 to ensure these baseline dependencies are met. gem5 dependencies can be found [[http://gem5.org/Dependencies|here]], and more gem5 information can be found [[http://gem5.org/|here]]. Since we build off of gem5, all of the dependencies of gem5 are also dependencies of gem5-gpu.

 +One dependency in addition to the gem5 dependencies is a CUDA installation to have access to nvcc and header files. When you have CUDA installed, export the following environment variable used during gem5-gpu build:
 +<code>
 +export CUDAHOME=/path/to/your/cuda/install/cuda

 +If you would like to test extensions to the PTX ISA, you may need to modify the Lex+Yacc ISA parser in GPGPU-Sim to enable these extensions. In order to do this, you will need to generate your own ISA parser source code within the GPGPU-Sim code base. Below are instructions for setting up gem5-gpu using the full GPGPU-Sim source to allow for these ISA modifications.
  
 You’ll need the “gpgpu-sim-sha” found [[http://goo.gl/S1ts6|here]]. **NOTE:** If you setup GPGPU-Sim from the public git server instead of pulling from our repositories, you may not be able to submit review requests to our GPGPU-Sim patches repository You’ll need the “gpgpu-sim-sha” found [[http://goo.gl/S1ts6|here]]. **NOTE:** If you setup GPGPU-Sim from the public git server instead of pulling from our repositories, you may not be able to submit review requests to our GPGPU-Sim patches repository

 +Below are quick start commands to build and run gem5-gpu with the x86 CPU ISA. For building and running gem5-gpu with the ARM32 CPU ISA, see instructions here: [[arm32_support|ARM32 Support]].

 <code> <code>
 cd gem5 cd gem5
-scons build/VI_hammer/gem5.opt --default=X86 EXTRAS=../gem5-gpu/src:../gpgpu-sim/ PROTOCOL=VI_hammer GPGPU_SIM=True+scons build/X86_VI_hammer_GPU/gem5.opt --default=X86 EXTRAS=../gem5-gpu/src:../gpgpu-sim/ PROTOCOL=VI_hammer GPGPU_SIM=True

 + 
 +You can also build using the pre-defined build options files (found in gem5-gpu/build_opts) as follows: 
 + 
 +<code> 
 +cd gem5
