SampleApp build failure on Ubuntu server 14.04

use these instructions instead http://docs.asp.net/en/latest/getting-started/installing-on-linux.html. The ones you are using are not ready yet for some scenarios. They will be ready by rc2

Thanks @shahid-pk. Unfortunately that doesn't work either, although the failure is different:

I followed the instructions to install coreClr: http://docs.asp.net/en/latest/getting-started/installing-on-linux.html

Here's my command history:

  5  curl -sSL https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.sh | DNX_BRANCH=dev sh && source ~/.dnx/dnvm/dnvm.sh
  6  source /home/ubuntu/.dnx/dnvm/dnvm.sh
  7  dnvm
  8  sudo apt-get install libunwind8 gettext libssl-dev libcurl4-openssl-dev zlib1g libicu-dev uuid-dev
  9  dnvm upgrade -r coreclr
 10  sudo apt-get install make automake libtool curl
 11  curl -sSL https://github.com/libuv/libuv/archive/v1.8.0.tar.gz | sudo tar zxfv - -C /usr/local/src
 12  cd /usr/local/src/libuv-1.8.0
 13  sudo sh autogen.sh
 14  sudo ./configure
 15  sudo make
 16  sudo make install
 17  sudo rm -rf /usr/local/src/libuv-1.8.0 && cd ~/
 18  sudo ldconfig

All steps reported success. I created an ran a little console application which worked fine.

Attempt to build the sample app:

 38  git clone https://github.com/aspnet/KestrelHttpServer.git
 39  ls
 40  cd KestrelHttpServer/samples/SampleApp/
 41  dnu restore
 42  dnx build
 43  dnx web

Which fails with the following exception:

add this package to the project.json file System.Runtime, version 4.0.21-beta-23509 under dnxcore50 or you can go all latest by getting latest version of the package with 'System.Runtime 4.0-21-*.
The sample may be outdated.
Next time you see some types missing use this site http://packagesearch.azurewebsites.net/ to find what package that type lives in.

I added System.Runtime to my project file:

{
  "version": "1.0.0-*",
  "dependencies": {
    "Microsoft.AspNet.Server.Kestrel": "1.0.0-*",
    "Microsoft.AspNet.Server.Kestrel.Https": "1.0.0-*",
    "Microsoft.Extensions.Logging.Console": "1.0.0-*"
  },
  "compilationOptions": {
    "emitEntryPoint": true
  },
  "frameworks": {
    "dnx451": {
    },
    "dnxcore50": {
      "dependencies": {
        "System.Console": "4.0.0-*",
        "System.Runtime": "4.0-21-*"
      }
    }
  },
  "commands": {
    "web": "SampleApp"
  }
}

Then dnu restore reported some NotFound errors:

NotFound https://api.nuget.org/v3-flatcontainer/microsoft.aspnet.internal.libuv-windows/index.json 157ms
NotFound https://api.nuget.org/v3-flatcontainer/microsoft.aspnet.internal.libuv-darwin/index.json 279ms
NotFound https://api.nuget.org/v3-flatcontainer/system.threading.tasks.extensions/index.json 164ms

dnx web gave the same error as above.

BTW, dnu restore also reported:

Installing System.Runtime.4.0.0-beta-23019

cesarblum commented on Jan 14, 2016

@mikehadlow Run dnu restore at the root of the repository. Then go into samples/SampleApp and you should be able to build and run it.

There's some pre- and post-restore logic in src/Microsoft.AspNet.Server.Kestrel that needs to be run before you can run the sample apps.

mikehadlow commented on Jan 14, 2016

Thanks @CesarBS. I ran dnu restore from the root then dnx web from samples/SampleApp. Now I'm getting the following error:

System.TypeLoadException: Method 'get_Configuration' in type 'WrappedApplicationEnvironment' from assembly 'Microsoft.AspNet.Hosting, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60' does not have an implementation.

You might be mixing an old DNX with newer packages. Update your DNX.

mikehadlow commented on Jan 14, 2016

I think I've already got the latest dnx:

$ dnvm upgrade -r coreclr
Determining latest version
Latest version is 1.0.0-rc1-update1
dnx-coreclr-linux-x64.1.0.0-rc1-update1 already installed in /home/ubuntu/.dnx

davidfowl commented on Jan 14, 2016

Not new enough. Your packages are RC2 and your DNX is RC1, that will not work. Run dnvm upgrade -u The -u is for unstable.

mikehadlow commented on Jan 14, 2016

Many thanks @davidfowl and @CesarBS! Now working:
