INSTALL GFORTRAN MAC PORT CODE

Now you should have installed Xcode and CLT to be able to run commands and compile code with Terminal(.app) and potentially also XQuartz. Visit the developer website at and follow the instructions.

I believe you still recieve a popup explaining that you need to install XQuarts when trying to use X11 though you might just as well install the software directly. Some modules of the Amber package uses X.org X Window System for dealing with GUIs, support for this is no longer the default in macOS in the form of the old X11.app so in order for this to work you need to install XQuartz which has replaced X11.app.

This step was necessary for AmberTools18 as Apple retired some tools that previously came with Xcode. Open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg Follow the on-screen instructions to install. Hence, you might need to install some missing header files by running the following command, opening a PKG installer which is shipped with Xcode10. The step below might no longer be necessary with the latest updates of the amber code though IвЂ™ll leave it here since I have installed these headers on my machine already and have yet had time to investigate if this makes a difference. Command Line Tools (CLT) is needed to run commands and compile using the terminal and is installed after Xcode has been installed by executing the following command in the Terminal(.app). For this вЂњhow-toвЂќ, Xcode 10.2.1 was used and you should install this software using the AppStore on your Mac. Regardless of which package manager or gcc source you select, you need to install Xcode. Installing Xcode and accompanying Command Line Tools If you run into issues I refer you to the AMBER mailing list for help rather than trying to comment here as I am not updating this page regularly enough to be able to help in any reasonable amount of time. Remember, only chose one source of installing compilers from as you may accidentally cause conflicts of installing more than one package manager or from more than one source of binaries at once. The process should still be the same regardless of the source one chooses for gcc/gfortran. However, not having enough time and a more acute lack of a stable and available virtual machine with macOS for testing I have had to limit myself somewhat. Earlier I have offered instructions for using вЂњMacPortsвЂќ och binary distributed versions of HPC gcc/gfortran.

INSTALL GFORTRAN MAC PORT HOW TO

I will now explain how to compile AmberTools19(/Amber18) with the package manager вЂњ HomebrewвЂќ and the Apple version of the C compiler package clang. With this explained I think it is time to get started. Some commands might require you to вЂњ side-scrollвЂќ to see the entire sequence as they might continue вЂњoff screenвЂќ. When you are expected to run commands in the terminal, they will be presented in this manner: You find this app in your Applications folder, in a sub folder called Utilities or by using Spotlight, the litle magnifying glass in the top right corner of the screen (alternatively through the keyboard shortcut cmd+space on your keyboard, assuming this is active) and search for вЂњTerminalвЂќ. This will require you to install some things and run some commands through the built in вЂњcommand interpreterвЂќ which on macOS is called Terminal(.app). It is now once again possible to use gcc as long as you are using the latest and patched version of whichever gcc version you choose.

INSTALL GFORTRAN MAC PORT UPDATE

Below different methods are presented to install the current version of AmberTools, where the method should be the same for Amber.ДЄfter the latest update of Xcode to 10.2.1, problems started emerging when trying to use a compiler other than clang. Installing Amber/AmberTools on macOS has become much easier though is not to be considered completely trivial.
