[thomtomdup]

Hello.
I tried to install the new release of e-linux.
I have create a new project with flutter-elinux to verify if it's my project but not.
I have this error when i run the build :

Can you help me about this issue ?

Thank you.
Regards

These message are not problem. Because the official flutter assumes the URL which the artifact is downloaded. If there is a chance to improve it, I will improve it, so I will keep the issue open.

Thanks.

[thomtomdup]

OK thank you but the problem is with that issue I can't build any project.
To be able to build, I had to used an old version of flutter e-linux that I had backup.

[HidenoriMatsubayashi]

Are you using proxy? Can you delete current flutter-elinux directory once? Then, git clone and flutter-elinux run?

[thomtomdup]

No proxy and the folder of flutter-elinux was renamed to flutter-elinux-old before git clone.

[HidenoriMatsubayashi]

I guess your internet speed is a little bit slow. Your network speed is good?

Artifacts for elinux can be downloaded by using the following command.

$ flutter-elinux precache --elinux

Hello.

I tried your solution but the issue is not solved.

After this i tried to build my app like i did before but i have some errors of build.

My process is the same than the wiki document : https://github.com/sony/flutter-elinux/wiki/Building-flutter-apps
( using docker to compile in arm64).

Error details :

Could you please help me to solve this probleme ? :)

My last version of flutter-elinux was 3.0.5 and i just tried to use the last version and the issues appears.

Thank you very much.
Best regards.

Hello.
Just for information, this is since flutter 3.3.0 version. I did some tests with différents versions of flutter-elinux.

Did you change something between 3.0.5 and 3.3.0 ? 😊.

Thank you.

[thomtomdup]

Hello.
I found the issue and solved it.
I needed to erase my elinux directory on my project and run flutter-elinux create to create the directory and all work good .
Also i saw that you forgot to add command parameter in the wiki .

Troubleshooting Part

flutter-elinux build elinux --target-arch=arm64 \
     --target-sysroot=<Absolute_path_to>/ubuntu18-arm64-sysroot \
     --system-include-directories=/usr/aarch64-linux-gnu/include/c++/${version}/aarch64-linux-gnu

You forgot to add this :
--target-compiler-triple=aarch64-linux-gnu \

Thank you,
Regards

我猜你的网速有点慢。你的网速好吗？

可以使用以下命令下载 elinux 的工件。

$ flutter-elinux precache --elinux

Hello, it is a little difficult to access github where I am, so I can't use the download method of automatically connecting to github. I can download these packages manually, but I don't know which directory to put them in to skip the automatic download? I don't even know whether to download to the flutter directory, the flutter-elinux directory or the project's directory.
Can I download manually and skip the automatic download? What directory should it be placed in?
Or can I change a dart file to change the download url point?

Unfortunately, no. But you might be able to use ELINUX_ENGINE_BASE_URL. Is it enough for you use cases?
See https://github.com/sony/flutter-elinux/blob/main/lib/elinux_cache.dart#L101
