It would probably take a week or more of effort to get it compiled if you have a lot of experience compiling code.<div class=""><br class=""></div><div class="">All our development effort has been on ChimeraX for several years so we cannot work on a Chimera Linux ARM64 version. We also do not have a ChimeraX version for Linux ARM64. ChimeraX is much easier to compile since we don't compile all the third-party libraries. But it does need precompiled versions of those third-party binaries so it won't be quick and simple for Linux ARM64. We are currently working on macOS ARM64 since most new Mac computers are now using ARM64 CPUs.</div><div class=""><br class=""></div><div class="">For now I think we simply cannot support Linux ARM64 ChimeraX because we have too much work adding new features to the program.</div><div class=""><br class=""></div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>Tom</div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Nov 14, 2021, at 7:55 PM, Chen Zhiqiang via Chimera-dev <<a href="mailto:chimera-dev@cgl.ucsf.edu" class="">chimera-dev@cgl.ucsf.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta charset="UTF-8" class=""><div class="WordSection1" style="page: WordSection1;
