Pi 4, can't compile/produce qbittorrent-nox binary

[joshft91]

Apologies for writing another issue already, I seem to be having an issue at the very end of attempting to produce the actual qbittorrent-nox file.

Current process:

1. Ran ./qbittorrent-nox-static.sh all
   • Appeared to work fine all the way to the last step when attempting to compile/build qbittorrent
   • No qbittorrent-nox file was produced in /qb-build/bin
2. Restarted the Pi 4
   • Ran ./qbittorrent-nox-static.sh all again to ensure nothing was weird after installing dependencies previously
   • Encountered same issue described below
3. Ran ./qbittorrent-nox-static.sh boost (required to build qbittorrent-nox since it gets deleted after running the qbittorrent module)
4. Ran ./qbittorrent-nox.static.sh qbittorrent`
   • Works fine until the following logs are produced below
5. No binary produced

It appears to be something around potentially not finding the -l:libtorrent.a file? Continuing to try a couple things but wanted to see if this error is anything you've seen before. Cheers.

What you should do it delete the build folder and start again.

./qbittorrent-nox-static.sh all

After you can look at the build logs in qb-build/logs to see what build failed.

Thanks, I'll get back to you; need to set up my Pi4 after it crashed due to something else this morning. Will see if a clean install will fix the problem I was encountering.

Alright, it seems to be some sort of libtorrent compile/build issue that I'm running into. I noticed when doing the libtorrent module that at one point it will freeze for quite a while and then eventually I get this error: g++: fatal error: Killed signal terminated program cc1plus

Seems that the more specific error is this:
...failed gcc.compile.c++ bin/gcc-8/release/address-model-32/crypto-openssl/cxxstd-17-iso/link-static/threading-multi/src/session_impl.o...

The last few lines of libtorrent.log.txt are here:

...skipped <pbin/gcc-8/release/address-model-32/crypto-openssl/cxxstd-17-iso/link-static/threading-multi>libtorrent.a(clean) for lack of <pbin/gcc-8/release/address-model-32/crypto-openssl/cxxstd-17-iso/link-static/threading-multi>src/session_impl.o...

Which lines up with the issue seen when attempting to build qbittorrent

linking qbittorrent-nox
/usr/bin/ld: cannot find -l:libtorrent.a

Not sure why I wouldn't be able to compile/build, seems like everything else is okay.

[userdocs]

it hard for me to help since I don't have a pie and it's a 32 bit os.

I am not sure where the problem is it may be the same error as here

arvidn/libtorrent#5117

[joshft91]

No problem, thanks for at least reading. I'll close this out since it does appear to be something OS/32-bit related. I'll dig into building libtorrent and see if I can go from there. Thanks

[joshft91]

I finally got the latest version of qBittorrent (4.3.3) built after working through the issues I was encountering above. Turns out it was due to Out of Memory issues when building libtorrent. I've outlined the way I solved the problem below. Thanks @userdocs for the responses along the way.

Hardware: Raspberry Pi 4 2GB
OS: Raspberry Pi OS 64-bit

Problem: ./qbittorrent-nox-static.sh dies when attempting to build the libtorrent module
Fix: Create a 1Gb swapfile according to these instructions and attempt to build libtorrent again.

Libtorrent was then created successfully allowing me to then run ./qbittorrent-nox-static.sh qbittorrent and get the qbittorrent-nox binary.

[userdocs]

That is good to know, thanks.

Does the binary run with no issues?

[joshft91]

It did, yep. No issues or anything, I just executed the binary and it started with no problem on port 8080. I suspect that there's not a lot of Pi4 2GB models out there that people are building ... it looks like even with 4GB it would have no problem.
