Dear Matt: Thanks for your helpful reply! It saves me a lot of time that should have been used to try to solve these problems. I think I may try other software like Larch :) Best regards, Maolin Wang -----原始邮件----- 发件人: "Matt Newville" 发送时间: 2022-01-23 05:04:47 (星期日) 收件人: "XAFS Analysis using Ifeffit" 抄送: 主题: Re: [Ifeffit] Question_Demeter installation on Mac with Apple Silicon M1 Hi Maolin, On Thu, Jan 20, 2022 at 11:13 PM 王茂林< maolinwang@pku.edu.cn > wrote: Dear IFEFFIT members, Here I want to install Demeter in my Mac with M1 pro, I followed the processes in https://bruceravel.github.io/demeter/documents/SinglePage/macinstallation.ht... (First, install Xcode and Xcode command tool; Then install Macport). But when I type " sudo port install xorg-server demeter in the terminal and after agreeing to the terms, there came to a warning, shown in the attached figure. What should I do to install it on my mac? And the log file (also attached) seems like Demeter doesn't support the M1 with ARM architecture? I'm not surprised that there is not a MacPorts port to MacOS M1/ARM yet. As it turns out, I'm still waiting (7+ weeks!) for the delivery of an M1 Macbook Pro. I have not built any of the compiled binaries or libraries used by Larch (say, Feff, or reading XDI file) for M1/ARM yet myself (or tried to configure any build farms to do so). FWIW, there was a bit of discussion on the MacPorts version of this software: https://millenia.cars.aps.anl.gov/pipermail/ifeffit/2021-November/010334.htm... The message there (perhaps not a "conclusion") was that supporting Demeter and Ifeffit on macOS is very hard. Just to be clear, the error you see is with PGPLOT, last released in 2001 (sic). Ifeffit (last release in 2010, bug fixes until 2014) never required PGPLOT - it was optional. Demeter (last release 2018) never used the PGPLOT functionality. For sure, porting of these tools would be easier if PGPLOT was left out entirely, but porting code that is no longer being developed or supported is going to be an endless chore for someone. And as it turns out Perl+Wx+MacOS has always been extremely challenging and it appears that no one is working on it (wxPerl last released in 2017, for any system). Basically, I think that no one is going to work very hard on getting Demeter to work on macOS M1. It might be a good opportunity to try out the alternatives. --Matt
