Cross-compilation doesn't work on Ubuntu about qbittorrent-nox-static HOT 11 CLOSED

It looks like a PATH issue, and I cannot replicate it on a Ubuntu WSL2 i actively use.

You can try the docker method instead

from qbittorrent-nox-static.

Thanks for the URL, but I have no issues with installing the script. It runs fine.

I think gawk and bison are being built for the wrong architecture when cross-compiling.
My understanding is that the following command should build an aarch64 binary:

docker run -it -w /root -e "LANG=en_GB.UTF-8" -v $HOME/qbt:/root ubuntu:latest /bin/bash -c 'apt update && apt install -y curl && curl -sL git.io/qbstatic | qbt_cross_name="aarch64" qbt_qt_version="5.15" bash -s all'

It passes all the checks successfully:

 ✔ Dependencies installed!
 ● All checks passed and core dependencies are installed, continuing to build
 ● Script version: 1.0.4
 ● Install Prefix : ~/qbt-build
 ● Script help : ~/bash -h
 ● Using multiarch - arch: aarch64 host: ubuntu target: ubuntu

But then it fails to build glibc with the error I posted above.

First, I am not sure what you mean about installing the script when it was instructions to run the script via docker to avoid host system conflicts.

Second, this command works fine and successfully built it via docker with ubuntu 22.04

docker run -it -w /root -e "LANG=en_GB.UTF-8" -v $HOME/qbt:/root ubuntu:latest /bin/bash -c 'apt update && apt install -y curl && curl -sL git.io/qbstatic | qbt_cross_name="aarch64" qbt_qt_version="5.15" bash -s all'

Third, there is currently no replication of your issue. You are the only person having the issue.

My Debian CI runs are working fine, as you can see here.

https://github.com/userdocs/qbittorrent-nox-static/actions/runs/4297732051/jobs/7491066521

So the question is why do you have this issue that is not a script issue.

Maybe purge your ubuntu dockers images and pull new ones. If you are using the docker command above I can only assume your images are corrupted somehow.

Unless you can show how this is a script issue that i can replicate I'm not sure what I can do here.

Thanks for looking into this.

I get the same issue on an Ubuntu 22.04.1 live CD in a diskless VM, it has no image cache or any preexisting software. Simply installed docker (sudo apt install docker.io) and ran the same command as you.

I managed to build qB by removing the bison and gawk build steps from the script. The built qbittorrent-nox binary works correctly on a Pi 4B.

The problem is nothing explains why you have this issue that appears isolated to you, specifically.

Yours looks like this

Here is the script on Ubuntu latest where I skip gawk and bison and just install glibc.

There is something wrong here but it seems more likely a local issue than a script as this issue cannot be replicated.

from qbittorrent-nox-static.

Can you try this script

https://gist.githubusercontent.com/userdocs/2c09644e86e97a476f2fc034aa0d47d6/raw/e38c1824691912e5dd52a3ae3d515c245f051c59/qbittorrent-nox-static.sh

Only changes are not to install gawk bison and use apt instead.

	qbt_modules=("all" "install" "glibc" "zlib" "iconv" "icu" "openssl" "boost" "libtorrent" "double_conversion" "qtbase" "qttools" "qbittorrent") # Define our list of available modules in an array.
...
...
...
	if [[ "${what_id}" =~ ^(debian|ubuntu)$ ]]; then # if debian based then set the required packages array
		qbt_required_pkgs=("gettext" "texinfo" "gawk" "bison" "build-essential" "crossbuild-essential-${cross_arch}" "curl" "pkg-config" "automake" "libtool" "git" "openssl" "perl" "python${qbt_python_version}" "python${qbt_python_version}-dev" "python${qbt_python_version}-numpy" "unzip" "graphviz" "re2c")
	fi

The way I am thinking about this is that I can avoid the need to build gawk and bison, irrespective of this issue but it might also solve the issue you face.

So this tweak might indirectly solve your issue.

from qbittorrent-nox-static.

Ran this:

lxc launch ubuntu:22.04 --ephemeral qbt-build
lxc shell qbt-build
wget -q https://gist.githubusercontent.com/userdocs/2c09644e86e97a476f2fc034aa0d47d6/raw/e38c1824691912e5dd52a3ae3d515c245f051c59/qbittorrent-nox-static.sh
sudo su -
qbt_cross_name="aarch64" qbt_qt_version="5.15" bash qbittorrent-nox-static.sh all

Got this:

● All checks passed and core dependencies are installed, continuing to build
● Script version: 1.0.4
● Install Prefix : /home/ubuntu/qbt-build
● Script help : /home/ubuntu/qbittorrent-nox-static.sh -h
● Using multiarch - arch: aarch64 host: ubuntu target: ubuntu
● Skipping bison module installation
● Skipping gawk module installation
+ Installing glibc - https://ftp.gnu.org/gnu/libc/glibc-2.35.tar.gz
[...]

The resulting qbittorrent-nox binary was tested on Pi 4B and appears to be working fine.

Then I tested Docker:

docker run -it -w /root -e "LANG=en_GB.UTF-8" -v $HOME/qbt:/root ubuntu:latest /bin/bash -c 'apt update && apt install -y curl && curl -sL https://gist.githubusercontent.com/userdocs/2c09644e86e97a476f2fc034aa0d47d6/raw/e38c1824691912e5dd52a3ae3d515c245f051c59/qbittorrent-nox-static.sh | qbt_cross_name="aarch64" qbt_qt_version="5.15" bash -s all'

Same thing, binary built successfully.

Thank you!

What platform and OS are you building on? not the docker stuff, the main host?

from qbittorrent-nox-static.

The host is running Kubuntu 22.04 x86_64.

from qbittorrent-nox-static.

We may never know but this commit should provide a fix.
