Msbuild: Unable to compile msbuild from source on linux

Created on 22 Feb 2019  路  38Comments  路  Source: dotnet/msbuild

Steps to reproduce

Following instructions from https://github.com/Microsoft/msbuild/blob/master/documentation/wiki/Building-Testing-and-Debugging-on-Mono-MSBuild.md:

  1. clone msbuild repo
  2. check out xplat-master
  3. recursive submodule init update (nothing happened)
  4. ensure mono is in PATH and call 'make': ~/Projects/msbuild$ PATH=~/.mono/bin:$PATH make

Expected behavior

A working msbuild.exe

Actual behavior

Build started 2/22/2019 1:53:13 PM.
/home/kate/Projects/msbuild/artifacts/toolset/restore.proj : error : Unable to load the service index for source https://dotnet.myget.org/F/roslyn-tools/api/v3/index.json.
/home/kate/Projects/msbuild/artifacts/toolset/restore.proj : error MSB4236: The SDK 'RoslynTools.RepoToolset' specified could not be found.

Build FAILED.

Environment data

msbuild /version output: n/a, I don't have a msbuild.exe

OS info: debian 9 x64

If applicable, version of the tool that invokes MSBuild (Visual Studio, dotnet CLI, etc): mono built from source (latest master as of a couple days ago)

I checked my NuGet.config in ~/ and the one in the repo root and they both look okay. I don't have a proxy.

Most helpful comment

For an update, on latest xplat-master the process we're currently using to build on ubuntu-based continuous integration is roughly the following:

# in mono/
./autogen.sh --prefix=/mono-prefix/
make
make install
export PATH=/mono-prefix/bin:$PATH
cert-sync /etc/ssl/certs/ca-certificates.crt # this is only necessary the first time you build at the prefix. without it you will have no SSL certs = nuget won't work
# in msbuild:xplat-master/
./eng/cibuild_bootstrapped_msbuild.sh --host_type mono --configuration Release /p:DisableNerdbankVersioning=true "/p:Projects=./src/MSBuild.Bootstrap/MSBuild.Bootstrap.csproj" /p:AssemblyVersion=15.1.0.0

If anyone trying to build on linux can't successfully build using these steps, please let me know.

The documentation likely needs to be updated after our recent changes to infra-structure.

If you just want to build on linux, just checkout master and run build.sh. Nothing else should be necessary.

build.sh also doesn't work. Do I need to put mono in my PATH?

The recent build changes haven't been merged yet (https://github.com/mono/mono/pull/13053).
@kg Could you please share the binlogs from artifacts/*-MONO/log/?

radical picture radical on 28 Feb 2019

This is the only binlog in that folder
Toolset.zip

this looks weird: Restoring packages for .NETStandard,Version=v0.0..

radical picture radical on 28 Feb 2019

@kg no artifacts/Release-MONO/log/Toolset.binlog? I'm not sure what might be causing this.

  1. Hm could you share the full output from make? something like make 2>&1 > make.log.
  2. And maybe just tar artifacts/ and attach.
  3. Also, could you confirm the HEAD of your branch? (804bde742bdf9d65c7ceb672a3d5400c0c22e628 ?)
radical picture radical on 28 Feb 2019

Verified the HEAD and did a full reset + make clean to ensure working tree was clean. The artifacts folder is enormous so I can email it to you if you want.

Still not possible to build based on instructions. 'make' in root produces invalid substitution:

kate@reeir-debian2:~/Projects/msbuild$ PATH=/home/kate/.mono/bin:$PATH make
./eng/cibuild_bootstrapped_msbuild.sh --host_type mono --configuration Release --binaryLog --skip_tests
./eng/cibuild_bootstrapped_msbuild.sh: 11: ./eng/cibuild_bootstrapped_msbuild.sh: Bad substitution

Changing the shebang in that script to /bin/bash gets further but still fails:

./build.sh also does not work for current Microsoft/msbuild master. Same libgit errors.

libssl 1.0.0 is extremely deprecated as far as I can tell, 1.1.0 is available in debian and no amount of symlinking gets ./build.sh to find it.

At Ankit's suggestion I tried bypassing nerdbank via ./eng/cibuild_bootstrapped_msbuild.sh --host_type mono --configuration Release --binaryLog --skip_tests /p:DisableNerdbankVersioning=true:

Incidentally I have to edit the .sh files to replace /bin/sh with /bin/bash before they work, because they contain syntax incompatible with sh. That should probably be fixed.

OK, the ssl error is because from-source and from-package installs of mono don't have certificates. If you get your hands on cert-sync and build afterwards with nerdbank disabled you get a lot closer to a working build w/build.sh:

Build FAILED.

However this way of invoking build.sh only produces a netcore .dll and not a msbuild.exe. Not sure if that's because a final build step is being blocked by the failure to build those unit tests.

Using cibuild_bootstrapped_msbuild I get a different set of failures:

I am using mcr.microsoft.com/dotnet/core/sdk:2.2. Is there another Docker image I should be using to build? It would be nice to have a reproducible a Dockerfile rather than bash script.

jmcelwain picture jmcelwain on 3 Apr 2019

Nerdbank is, to my understanding, a problem in libgit2 where it requires libssl 1.0.0 - very old and deprecated by some Linux distros.
If you disable Nerdbank via /p:DisableNerdbankVersioning=true you can get past that problem, but I don't know what disabling it actually does...

kg picture kg on 3 Apr 2019

Thanks @kg.

I was able to get a bit further: ./eng/cibuild_bootstrapped_msbuild.sh --host_type core --configuration Release --binaryLog /p:DisableNerdbankVersioning=true

For some reason I had to remove --skip_tests and change to --host_type core. I'm using Docker image mcr.microsoft.com/dotnet/core/sdk:2.2.

Now failing with error: Definition/ProjectCollection_Tests.cs(1425,51): error CS0103: The name 'ThisAssembly' does not exist in the current context [/msbuild/src/Build.OM.UnitTests/Microsoft.Build.Engine.OM.UnitTests.csproj]

jmcelwain picture jmcelwain on 3 Apr 2019

I have also observed the ThisAssembly error, but it's an error in automated tests. If you examine your artifacts folder, you should have a MsBuild.dll that you can run as an executable (using mono or dotnet). Give that a try

kg picture kg on 3 Apr 2019

Just as an update for anyone else puzzled by the ThisAssembly error, it is apparently related to Nerdbank and specifically happens if Nerdbank is disabled. So that error does not indicate that you have broken anything, and if you get a usable Msbuild.dll output you might be ready to go.

kg picture kg on 4 Apr 2019

@kg Yes, I was able to successfully execute the following:
```
root@dd507ae2a6ce:/msbuild/artifacts# dotnet ./bin/MSBuild/Debug/netcoreapp2.1/MSBuild.dll

MSBUILD : error MSB1003: Specify a project or solution file. The current working directory does not contain a project or solution file.
```
:)

Still would like the regular documented build.sh script to work, though.

jmcelwain picture jmcelwain on 4 Apr 2019

I'm thinking of hacking out Nerdbank.GitVersioning. Arcade is going a different direction: https://github.com/dotnet/arcade/blob/master/Documentation/CorePackages/Versioning.md and some of the other design decisions made there make continuing to use it a pain, + this issue.

rainersigwald picture rainersigwald on 4 Apr 2019

Any progress on this?

KexyBiscuit picture KexyBiscuit on 11 Apr 2019

Current status:
Do not consider this blessed advice, but I was able to compile an msbuild.dll without any compile errors or script errors via this approach:
PATH=~/.mono/bin:$PATH eng/cibuild_bootstrapped_msbuild.sh --host_type mono --configuration Release --binaryLog --skip_tests /p:DisableNerdbankVersioning=true "/p:Projects=`pwd`/src/MSBuild/MSBuild.csproj" /p:AssemblyVersion=15.1.0.0

The p:Projects disables building of the test assemblies (since they're broken), the assemblyversion works around some binding redirect problems, and disabling nerdbank works around libgit/libssl issues.

I am not totally certain the resulting msbuild works right, though.

@kg Then I'm getting a MSBuild with invalid version (42.42...), however I'm looking for packaging it into a Linux Dist (with no Mono official support), how to resolve that?

KexyBiscuit picture KexyBiscuit on 19 Apr 2019

For mono we have a linux packaging process, the scripts and configuration are at https://github.com/mono/linux-packaging-msbuild. We've just recently been updating it and working on current documentation.

kg picture kg on 19 Apr 2019

For an update, on latest xplat-master the process we're currently using to build on ubuntu-based continuous integration is roughly the following:

# in mono/
./autogen.sh --prefix=/mono-prefix/
make
make install
export PATH=/mono-prefix/bin:$PATH
cert-sync /etc/ssl/certs/ca-certificates.crt # this is only necessary the first time you build at the prefix. without it you will have no SSL certs = nuget won't work
# in msbuild:xplat-master/
./eng/cibuild_bootstrapped_msbuild.sh --host_type mono --configuration Release /p:DisableNerdbankVersioning=true "/p:Projects=./src/MSBuild.Bootstrap/MSBuild.Bootstrap.csproj" /p:AssemblyVersion=15.1.0.0

If anyone trying to build on linux can't successfully build using these steps, please let me know.

I had been building msbuild using make all-mono in the xplat-master branch. This has been recently broken as an apparently non-publicly-available (not even on the dotnet-build myget feed) version of arcade SDK is being used.

borgdylan picture borgdylan on 7 Aug 2019

We shouldn't be using anything that's not public. The Arcade package should come from the https://dotnetfeed.blob.core.windows.net/dotnet-core/index.json feed.

rainersigwald picture rainersigwald on 7 Aug 2019

I have found that feed referenced in the NuGet.config file. However the bootstrap msbuild still complains that the requested version could not be found. I tried using the closest version available as mentioned by the restore error. That however caused other issues.

borgdylan picture borgdylan on 7 Aug 2019

@rainersigwald I have retried with the version of arcade referenced by the Microsoft/msbuild git repo and that also failed to restore for me. I'm also noticing that the global.json file refers to a .NET Core 3 preview build. All such builds are not available in the Ubuntu package repos from where I usually get builds of .NET Core and its tools.

borgdylan picture borgdylan on 9 Aug 2019

@borgdylan I hit that yesterday too. Looks like it's being tracked by the right folks at dotnet/arcade#3620.

rainersigwald picture rainersigwald on 9 Aug 2019

@borgdylan according to internal email, all of the Arcade packages should be available again now. It worked for me on the machine I mentioned earlier.

rainersigwald picture rainersigwald on 9 Aug 2019

I will retry my build. I can finally try building my library against NS 2.1, trying to have it ready by the time it actually hits GA.

borgdylan picture borgdylan on 10 Aug 2019

@rainersigwald The latest version vailable is still 1.0.0-dev.18424.13. Build 19408.13 is still unavailable.

borgdylan picture borgdylan on 10 Aug 2019

I have also tried installing the latest .NET Core 3.0 preview SDK on to my machine. Arcade is not biuilt-in to that and the same issue with getting it via NuGet still persists.

borgdylan picture borgdylan on 10 Aug 2019

It's possible there's a different issue, but let's first eliminate caches. Can you run

dotnet nuget locals --clear all

and try again? Note that this will delete a bunch of stuff and cause the next restore to do much more work than usual.

rainersigwald picture rainersigwald on 12 Aug 2019

@rainersigwald The cache was indeed the issue. The folder pertaining to arcade in the cache was owned by root whgich meant the build process was of a lower priviledge and hence could not write into it.

borgdylan picture borgdylan on 20 Aug 2019

The newer build code that has been pushed needs some hacks to run on Linux (many hard coded assumptions about macOS). Also restoring packages fails for some core corefx packages e.g. Threading. NuGet is timeing out in some cases or stating host is unknown in others. Using a browser yields the json or nupkg that NuGet was trying to get.
