That's what finally did it for me. I couldn't find anything that looked suitable in the myriad of Mono packages so I did a web search on install mono on Raspberry Pi (something like that) and I found a step by step tutorial. It installed mono-complete and took a while. Running Radegast reported some errors and such but it opened and I'm logged in. Like @Profaitchikenz Haiku I can see and wander through the inventory structure but no items get listed. That isn't important at all. If I need to do anything I would have had to fire up the tower and use a full viewer anyway. I'm logged in with the Raspberry Pi 32 bit OS but I'll add it to the 64 bit system that I'm using for the web. I think it should be fine. Thank you to everyone who contributed to me getting this far. Mainly Profaitchikenz and henri, but all who contributed and encouraged. Thank you I've still surrendered as far as a full viewer is concerned though.

Yes, I think the problem with others is likely to be the repositories they are querying. It was my fault for assuming I was running synaptic via a front end that misled Phil earlier. Sometimes I can be wr- wr- wr- - not quite optimal. 1 1 Link to comment Share on other sites More sharing options...
Profaitchikenz Haiku Posted October 1, 2022 Share Posted October 1, 2022 (edited) A question for Henri, Coffee or Beq: how much work would be entailed in updating the Radegast 2.12 source to implement inventory via http and the newer login system? If it's a team-week then I appreciate it's probably not worth bothering over, but if it's a couple of hours I'm wondering if it's worth creating a Radegast fork from 2.12 targeting the Raspberry Pi specifically.

Nicky Dasmijn Posted October 2, 2022 Share Posted October 2, 2022 So I figured I use a rainy sunday to go down into my devil's workshop, pull out my old rpi port and see if it still works. For the authentic experience I did all the compiling on a RPI 4 that has 8GB. - Rebuilding the 3p libraries takes about 110 to 120 minutes. - Building the viewer took about 8 to 9 hours (not sure, I roughly came back home after that time it look if it was done) Time it took me to port my old changes and fix some new issues not included. But tada To answer @Monty Linden darkest and deepest hunger for knowledge: Yes, it can be done. Should it be done, lolnope. The viewer runs like a slow mess with 4 FPS as can be seen. 3 Link to comment Share on other sites More sharing options...

With future/arriving SBCs using the new RK3588, you will likely be able to double or triple that FPS rate when compared to the PI4B RK3399 I'll probably buy one (once proper Linux support is available) next year... I would also be interested to know if you can compile the current Cool VL Viewer release (v1.30.0.19) on your PI, using its current pre-built arm64 libraries.

Though I haven't tried the older Radegast myself recently, I'd suspect that like the Lumiya viewer it would still work as expected in Opensim for Inventory and logins since the developer by request, used an either or approach to the newer HTTP protocol vs the older UDP. The login for Lumiya still works in S/L but like Radegast, the inventory no longer does. Edited October 2, 2022 by Arielle Popstar Link to comment Share on other sites More sharing options...

You should be able to compile the viewer nonetheless, using the ”--ignore-warnings” option (or ”-i”, for short) in the linux-build.sh command line, i.e. ./linux-build.sh -i But I'll try and (blindly, since I cannot test) fix those warnings. EDIT: the missing ”asm” is likely due to your gcc compiler being (strangely, since I'm not seeing this happening with gcc for x86_64) too strict about the C standard. Try and change 'set(CMAKE_C_FLAGS ”${CMAKE_C_FLAGS} -std=c11”)' for 'set(CMAKE_C_FLAGS ”${CMAKE_C_FLAGS} -std=gnu11”)' line 134 of linden/indra/cmake/00-Common.cmake EDIT3: the implicit posix_memalign issue should be fixed after inserting '# include <stdlib.h>' before '# include ”sse2neon.h”' in linden/indra/libopenjpeg/dwt.c and linden/indra/libopenjpeg/mct.c Not sure why sse2neon.h is not including stdlib.h by itself...

Phil Deakins Posted October 3, 2022 Author Share Posted October 3, 2022 (edited) I am so impressed with this continuation and getting a full viewer to actually run. Even if I understood a word of what's being discussed, it's not for me. When I need a full viewer, I need more than 4 fps.
