I personally have some code run with the same 11.2.0 gfortran on Linux well and can also run on Windows, but on M1 it can give me segment 11 error. However I am not sure if gfortran (or gcc) is fully compatible with M1 chip now. If your code is CPU bound, you perhaps will not see too much performance gain from M1 chip especially if your Intel chip is relatively not too old. It your code is memory bound, you will see performance gain from M1 chip, since Apple uses HBM which is designed particularly for M1.

You need to de-select the Python part if you want to install OneAPI on M1 Mac. Also the Python distribution in Intel OneAPI will fail when install on M1 Mac.
The Xcode stuff you mentioned is for Intel OneAPI, however Intel OneAPI does not optimize for M1, so the speed of Intel Fortran will be the same as gfortran with -O0 or at best -Og. I have not used mpich but a quick search with brew info mpich does show it exi… Once setup, you can install gfortran with the command: brew install gfortran. I have tried both, and currently use Homebrew. What is the most easy way to use gfortran + mpi for M1 chip Mac?Ī lot of Apple computer users (both Apple M1 chip and Intel x86 chip) use Homebrew or MacPorts to install and manage packages from the command line on their macOS computers.

Any suggestions on how to fix this problem and get gfortran running on my M1pro?ĭoes `sudo apt install gfortran mpich` support Apple M1 chip? I googled this and found several suggestions but some seem outdated and I am not sure how to proceed. I tried re-installing gfortran from Downloads (this time without the period at the end):
I tried to compile a test program but it failed,Ĭollect2: error: ld returned 1 exit status Tar: Error exit delayed from previous errors. There appeared to be one error at the beginning of the install,īut the rest of the install looked fine and it ended with I then went to the Downloads directory on my Mac and typed Applications/Xcode.app/Contents/Developer I’m not sure if Command Line Tools are installed, but when I type During the installation it did not ask me anything except whether I wanted to install Rosetta, which I did. Before the upgrade, I used pkgutil to check if Xcode CLT was installed and I got. Id installed Xcode Command Line Tools using Homebrew. Now I’m trying to install gfortran.įirst I installed Xcode from the App Store on my Mac. Ive upgraded to macOS 11.3 from macOS 11.2.3. I just got a MacBook Pro with the M1 pro chip.
