Cannot build 3.1.1 in docker container anymore.

[toneman77 0]

Hey guys.

When trying to build emby-server in a docker container, the following worked untill 3.0.8500:

sudo apt-get install -y --no-install-recommends \                                                             
    ca-certificates \                                                                                         
    git \                                                                                                     
    libmono-system-core4.0-cil \                                                                              
    mono-devel  \                                                                                             
    mono-runtime  \                                                                                           
    mono-utils  \                                                                                             
    mono-xbuild \                                                                                             
    wget                                                                                                      
cd $HOME \                                                                                                    
    && git clone --depth 1 https://github.com/MediaBrowser/Emby.git

I then change to Tools/Linux_Build_Scripts/ and launch MediaBrowser.Mono.Build.sh

 

But since 3.1.1 (I must have missed 3.1.0) I get:

...

========================================
           Requirements
========================================
           
Check if folder mediabrowser exist

MSBuild auto-detection: using msbuild version '4.0' from '/usr/lib/mono/4.5'.
MsBuild.exe does not exist at '/usr/lib/mono/4.5/msbuild.exe'.

Result is the same, no matter if I use a debian docker or ubuntu.

What did I do wrong? Anything I am missing here?

Hi, why not just follow the Docker instructions from the website?

[toneman77 0]

Hi. you mean this: https://github.com/MediaBrowser/Wiki/wiki/Docker-Getting-Started ?

That only builds a docker container with an already installed emby in it. I like building stuff and mostly for the sake of learning, that's why I build some packages myself.

[Luke 40079]

I see. Make sure you have mono 4.6. You will need that in order to build now.

I adjusted the instructions at github and used 4.6.2 as the version. Installed all the prerequisites. Sadly, still the same error.

I then searched around more and found this error stating that the wrong version of nuget ignores the correct path to xbuild and looks for msbuild.exe. This issue is fixed if I understood everything correctly with nuget 3.5 upstream. So I downloaded the current release from here and placed it in the NuGet folder.

 

And now I get this error:

========================================
           Requirements
========================================
           
Check if folder mediabrowser exist
mediabrowser exist, checking for old binaries folder

MSBUILD: error MSBUILD0005: Invalid syntax. Property name and value expected as <prop name>=[<prop value>]

Ok, well. The line in the MediaBrowser.Mono.Build.sh script that triggers the error is:

mono Nuget/nuget.exe restore MediaBrowser.Mono.sln

So i searched around and found out that nuget can be more verbose, so I changed into the main Emby folder and executed: (also tried to add verbosity in the script itself. result is the same)

~/Emby# mono Nuget/nuget.exe restore MediaBrowser.Mono.sln -Verbosity detailed

and the result was:

NuGet Version: 3.5.0.1938
MSBuild auto-detection: using msbuild version '14.0' from '/usr/lib/mono/xbuild/14.0/bin'. Use option -MSBuildVersion to force nuget to use a specific version of MSBuild.

And now after 2h of searching, I'm lost...

[scr09 2]

I have the same error trying to build Emby with the same instructions on Ubuntu (not for docker). mono is at version 4.6.2.

[scr09 2]

I fixed my error and successfully compiled by commenting this in the build script

#mono Nuget/nuget.exe restore MediaBrowser.Mono.sln

and installing referenceassemblies-pcl

apt-get install referenceassemblies-pcl

Thanks for reporting back !

Well at first I had some major problems because I build on debian, but run on alpine linux. Then I changed to tklx (smaller debian) but that didn't work out either. After using debian:wheezy in my Dockerfile, everything ran. Thanks a lot.

The one thing I had to do manually is make a symbolic link:

ln -s /usr/lib/x86_64-linux-gnu/libsqlite3.so.0 /usr/lib/libsqlite3.so

or else emby crashed on start. @scr09: did your build run without manual intervention?

 

Out of interest: What does "...nuget restore..." and why is it not neccesary?

@scr09: you are my hero (emby devs/admins are heroes anyways)

 

@Luke: Somebody should update the instructions @github, in case someone else tries to build versions higher than 3.0.xxxx

 

Thanks a lot guys
