Stuck loading files in UNetSim when launching with "-ip 0.0.0.0" #84

Open brodiealexander opened 1 year ago

brodiealexander commented 1 year ago

Context:

All tests were performed on an M1 MacBook Air running macOS 13.2 using unet-community 3.4.0

When running UNetSim via "bin/unet -ip 0.0.0.0 sim" the simulator web page will perpetually be at "Loading files...".

This result was seen under the following testing environments:

When testing with IP = 127.0.0.1, everything loaded correctly under macOS 13.2

Hi @brodiealexander. Apologies for taking a while to come back to this. Were there any errors in the log files? That "Failed to fetch simulation status" indicates that the ShellAgent didn't respond to the Web Interface when it queried for the status of the current simulation.

@notthetup and @brodiealexander : works fine on my macbook pro M2.

uname -a                                                                                                                          ─╯

@notthetup : On a side note, newer version of unet-3.4.4 - phy yoda is compiled with the newer version of glibc (it may be compiled with gcc-11 and my gcc version of ubuntu 20.04 distribution and version only is gcc-9 and therefore only provides glibc_2.31 (I guess)). There should be backward compatibility, and it should support the older version of ubuntu. Any thoughts ?

here is some more info if needed :

Thanks @patel999jay . Let me explore how we can support this.

patel999jay commented 3 months ago

@notthetup : any updates on this ?

patel999jay commented 2 months ago

@notthetup : any updates, we can not run this now on our newer jetson orin nano as well, Any suggestions ?

P.S.: we re-installed the portaudio, i rebuilt the portaudio as well (NO LUCK).

@patel999jay

Unet audio is not supported on Linux/ARM for now. We'll explore if we can also bundle a version that also supports Linux/ARM in the future. Currently supported platforms are..

Linux/x86 macOS/x86 macOS/ARM

We did publish a build for Linux/ARM in the past. You can see if you can use that. https://github.com/org-arl/unet-doc/raw/master/docs/downloads/unet-community-pi-3.1.0.tgz

We'll consider adding Linux/ARM to this list in the future. Lots of changes coming to UnetStack soon, so will have to figure out how/when things get released.

On the earlier issue with glibc combat. I did manage to get to the bottom of it. unet-v3.4.4 should be compiled on Ubuntu 18.08. So it should be compatible with anything newer than that.

@notthetup : Thanks, I will try this build for Linux/ARM.

patel999jay commented 2 months ago

@manuignatius : still have the same issue on new jetson nano orin. I followed the same steps outlined in the post you mentioned. It does work on RPi, very strange.

notthetup commented 1 month ago

@patel999jay I think it's an ARM32 vs ARM64 issue. https://github.com/org-arl/unet-doc/raw/master/docs/downloads/unet-community-pi-3.1.0.tgz is compiled for ARM32. The Jetson Nanos are ARM64.

Let me take a look to see if it's possible to recompile the the shared library for ARM64.
