Use for example the entire gcc@11 package:NOTE: For the M1/ARM architecture, you must use the Rosetta2 Intel binary translation to install your Homebrew compilersfor use with HEASoft, as follows:
Python on a Macintosh running Mac OS X is in principle very similar to Python on any other Unix platform, but there are a number of additional features such as the IDE and the Package Manager that are worth pointing out. Getting and Installing MacPython ¶. Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. Doing it Right¶. Let’s install a real version of Python. Before installing Python, you’ll need to install GCC. GCC can be obtained by downloading Xcode, the smaller Command Line Tools (must have an Apple account) or the even smaller OSX-GCC-Installer package.
So in Catalina these runtimes will still be available. Also, from the same document. Use of Python 2.7 isn’t recommended. This version is included in macOS for compatibility with legacy software. Future versions of macOS won’t include Python 2.7. Instead, it’s recommended that you run python3 in Terminal. $ pip2 -V # pip pointing to the Homebrew installed Python 2 interpreter $ pip -V # pip pointing to the Homebrew installed Python 3 interpreter (if installed) Virtual Environments ¶ A Virtual Environment (commonly referred to as a ‘virtualenv’) is a tool to keep the dependencies required by different projects in separate places, by creating.
1) Make sure Rosetta is installed:2) Install XQuartz version 2.7.11, which is Intel architecture.
3) Install Homebrew, prefacing the curl command with the Rosetta Intelprefix 'arch -x86_64', for example:4) Install the Homebrew packages gcc, perl and pythonusing the same Rosetta Intel prefix (and this assumes you used the newdefault Homebrew install location for Apple Silicon of /opt/homebrew):5) Set the compiler variables as above.
Use for example the entire gcc11 package:If you use MacPorts, please refer to theMacPorts Migration pagewhen updating your OS to avoid portability issues.
NOTE: For the M1/ARM architecture: as discussed forthe Homebrew compilers above, you will need to install your MacPortscompilers using the Rosetta2 Intel binary translation. This approachfor MacPorts has not been widely tested at the HEASARC, but furtherguidance may be forthcoming.
Python For Mac Catalina
These tar files unpack in /usr/local:
Please note that on macOS Catalina (and newer)these compilers are not currently supported for building HEASoftdue to the additional include and library path requirements notedon the HPC page.
