TRS-80 emulation 2023

Although I started TRS-80 emulation using SDLTRS, I will no longer be using/recommending it. I just tried running it, only to realize it’s not installed on my system. I thought I might just rebuild it…only to get “/usr/bin/ld: cannot find -lXt: No such file or directory”. Now maybe that error is easy to fix…I didn’t even look. However, what further errors might I get? The program was last updated in 2010. So why go through the hassle when trs80gp is still being actively updated AND there is an active discord channel AND it already includes the ROMS AND it includes the Coco, AND the author recently replied to my email.
