I'm installing flutter in a centos7 docker container. It's complaining that there are executables that can't be executed. A solution is there, but not for centos7:

[!] Flutter (Channel @{u}, v0.0.0-unknown, on Linux, locale en_US)
    ✗ Downloaded executables cannot execute on host.
      See https://github.com/flutter/flutter/issues/6207 for more information
      On Debian/Ubuntu/Mint: sudo apt-get install lib32stdc++6
      On Fedora: dnf install libstdc++.i686
      On Arch: pacman -S lib32-libstdc++5

A search on https://pkgs.org for lib32stdc++6, libstdc++.i686, lib32-libstdc++5didn't show a package for centos7. The github issue does not mention centos at all.

Which package of lib...++ do I need to install in my centos7 docker container to get flutter running?

This issue seems to be related to Flutter version Unknown

I have installed the newest git version as described here. However I'm still getting the same error.

What finally fixed it was this comment hidden in a Github Issue:

https://github.com/flutter/flutter/issues/6207#issuecomment-373100050

cd flutter/bin/cache/artifacts/engine
cp android-arm64-profile/linux-x64/gen_snapshot android-arm-profile/linux-x64/gen_snapshot
cp android-arm64-release/linux-x64/gen_snapshot android-arm-release/linux-x64/gen_snapshot

Update October 2018: We have moved away from this fix, as the app built this way crashes on the device. The resolution was to build flutter apps not on centos7. We now use a Docker Container based on this Dockerfile:

  • Used this Dockerfile to reproduce build problems on travis. Not a perfect match of travis, but works great! Would be nice if there was a version with the emulator already started. I think docker can support that, not sure if travis can. Then this travis integration testing would run faster: https://travis-ci.org/brianegan/flutter_architecture_samples – mmccabe Oct 30 '18 at 07:33

For CentOS 7.x, try installing libstdc++ package.

Query for package: yum search libstdc++

Install package: yum install libstdc++

libstdc++ is a part of the standard distribution for CentOS 7.x
