Tor-browser

[buhtz]

I am sorry for open this as an issue. But I couldn't find a better place.

I want to run Tor-browser via box86 on a Raspberry Pi 4 with Raspberry Pi OS (based on Debian buster).

The build of box86 worked well on the Pi 4. Very nice. I downloaded the x86 32bit linux version of tor-browser. But the start process is to complex I think.

When I do start-tor-browser.desktop I got thet "Tor Browser requires a CPU with SSE2 support." error. I tried to dive deeper into the tor folder structure to find out if box86 runs in the background.

cd ~/Downloads/tor-browser/Browser/
./firefox

Box86 with Dynarec v0.2.3 46114235 built on Sept 28 ...
Error: loading needed libs in elf ./firefox.real

Box86 itself runs I think. Any idea how to solve it?

Not sure box86 can run that. Try to use BOX86_LOG=1 ./firefox to have more detail on what lib is missing...

Thank you so much for your help.

I see libatomic.so.1 is "missing". What is the background here and how to treat that?

btw: I am sure that simply starting ./firefox won't bring up a full working tor-browser. Because of that the main problem here is that the recommand way to start tor-browser via start-tor-browser.desktop does not invoke box86 (because of the SEE2 error). The Excec line in there looks a bit complex for me and I do not understand what it does.

Here is the full start-tor-browser script.

for the libatomic.so missing, this lib is not wrapped, so you should grab an x86 version of that lib and copy the binary in the current folder.

For ./Browser/start-tor-browser doing an error with SSE2 error, that's strange. Box86 emulate SSE2 extension, so it should be detected. There must be something else going on there. I may try to run the thing at some point, to see if I can see something.

[ptitSeb]

Oh, it's a script. Ok, I see. Well, issue is there: https://gist.github.com/Codeberg-AsGithubAlternative-buhtz/926f6c843ad43b3fd2bee63ab061bdac#file-gistfile1-txt-L99-L102 comment those lines in the script to avoid the test...

[buhtz]

Thanks for your help. With commenting the test lines the run keeps silent without any error. I was not able to find a lib atomic to download somewhere. And I do not want to install a virtual linux somewhere just to get this file. I think I will give up at this point.

I want to run Tor-browser via box86 on a Raspberry Pi 4 with Raspberry Pi OS (based on Debian buster).

There are ARM builds of Tor Browser here. You can easily install it with Pi-Apps. @ptitSeb I suggest you close this issue.

[buhtz]

The ARM builds are not from a trustfull source. No option.

This issue was not about runnig tor browser on ARM64. It was about running it with box86 o ARM64.

[ptitSeb]

So, did you retry with latest box86? Shall the ticket be closed?

[buhtz]

Thanks for asking back. I switch to another operating system. I'm now using an original Debian (but special) image for Pi's from http://raspi.debian.net/
