Hello all, I am getting started with the gem5 simulator on my Mac 10.15.3. I started with "Building gem5" using commands mentioned on " https://www.gem5.org/documentation/learning_gem5/part1/building/";.
However, I am having issues building it. Since the commands mentioned on the page are for Ubuntu, I made some changes for "homebrew" on MAC. For the commands mentioned in step 1 " sudo apt install build-essential git m4 scons zlib1g zlib1g-dev libprotobuf-dev protobuf-compiler libprotoc-dev libgoogle-perftools-dev python-dev python" I modified and executed the following: 1. *build-essential : *I have installed xcode as it installs compilers and supporting utilities. xcode-select --install Version 11.3.1 2. *git* brew install git 3.* m4* brew install m4 4. *scons* brew install scons 5. *zlib* brew install zlib 6. libprotobuf-dev brew install libprotobuf-dev For installing protobuf version 3.12 , I followed the commands mentioned here: https://medium.com/@erika_dike/installing-the-protobuf-compiler-on-a-mac-a0d397af46b8 7. perftools brew install google-perftools 8. brew install libboost-all-dev After all these steps, I did git clone : git clone https://gem5.googlesource.com/public/gem5 After this I am trying to build it using scons with the following command : scons build/X86/gem5.opt This command results in the following error along with creating a "build" folder with a file named "variables.global" : scons: Reading SConscript files ... Warning: Failed to find git repo directory: a bytes-like object is required, not 'str' TypeError: argument should be integer or bytes-like object, not 'str': File "/Users/niveditagaur/Documents/Internship_Projects/gem5/SConstruct", line 355: main['GCC'] = CXX_version and CXX_version.find('g++') >= 0 The file variables.global has the following data written : PYTHON_CONFIG = ['python2.7-config', 'python-config'] I re-installed python but had no success. Kindly advise on how to successfully build and compile gem5 on mac. -- Nivedita Gaur
