Warning related to libstdc++ about deno_docker

[danopia]

Deno 1.10 is out (as 1.10.1) and libstdc++ is no longer required when building an Alpine image.

Once this repo is updated to 1.10 the warning should be gone as well. 🎉

Could this be related. The Deno app runs fine from the commandline.

@martijnvanschie This looks to me like an unrelated issue. It looks like your application gave an undefined to oak.

[hayd]

yes, fixed in 1.10.1. and dep removed by @kinghat 💪

Sadly I am not sure how to hide those warning lines. Does deno still run normally aside from those 5 (!) lines?

[openjck]

So far, yes! I haven't used it extensively yet, but it seems to work fine.

This issue (in a different context) seems identical or at least related : sgerrand/alpine-pkg-glibc#80

[jsejcksn]

Is this only an issue on the alpine build or does it affect other images as well?

[hayd]

Pretty sure this is only alpine here, but any distribution which has an unnamed build of libstdc++ will see the same issue.

Hi, I'm getting the same error on my docker image using hayd/alpine-deno:latest. After that I also get the following error:

paint-manager_api  | error: Uncaught (in promise) TypeError: Cannot read property 'router' of undefined
paint-manager_api  |       if (!middleware.router) {
paint-manager_api  |                       ^

Could this be related. The Deno app runs fine from the commandline.

Thanks.

@danopia I checked the oak Github following the stack trace and its on the RouterMiddleware instance in the router class.

I reported an issue in the oak repo.

Its just that a local docker run version starts normally so just wondering if the image might somehow be missing something Deno related.

@hayd yes, just tested new build and no more warning 👍
