Does any one received "Predefined type 'System.Object' is not defined or imported" when running build-test (after successful build)?
Karel Zikmund
@karelz
For everyone: You don't need to block on being assigned the issue (it is just convenience for everyone). Just state the intent of working on something in comments, so others don't work on the same thing ...

@leotsarev that's a weird one. In general: build & build-test is what all team members use + our regular contributors + our CI, so any failures (beyond potentially rare flakiness of a test or sensitivity to environment) is suspiscious
did any test execute for you at all?
Leonid Tsarev
@leotsarev
No.
Ouch, nevermind, I tried to run build and got " DIA SDK is missing" and it seems to be mentioned in the docs
Karel Zikmund
@karelz
yeah, that's a nasty one - the build should have clearly failed
if it was not clear, it is something for us to improve on
if that's the case, please file a new issue adding full log how the failure looks like and that it was not clear it failed right away
(we will eventualy fix it)
Leonid Tsarev
@leotsarev
I was under impression that successful first sync means successful first build
Karel Zikmund
@karelz
oh, if something in the docs lead you to that, point me to it, we can try to improve it
Leonid Tsarev
@leotsarev
Sorry for this, it's my fault
Karel Zikmund
@karelz
ok, it happens to all of us :)

@laurentkempe which tests fail?

Anyone hitting c1 : fatal error C1083: Cannot open source file: 'C:\Projects\corefx\src\Native\Windows\clrcompression\zlib-intel\adler32.c': ?
One of many similar errors building c:/Projects/corefx/src/Native/../../bin/obj/Windows_NT.x64.Debug/native\install.vcxproj

@ViktorHofer
@laurentkempe running tests inside currently does not work. Please use the console: msbuild /t:RebuildAndTest inside the test project where its csproj lives
Good Morning all! I'm a member of the team and working from Europe which means I should be available to any questions staying now 😁

@mikhailshilkov
Hi @ViktorHofer and all
Viktor Hofer
@ViktorHofer
@Mpdreamz when do you hit these errors? By calling .\build.cmd or by doing something special?
Mikhail Shilkov
@mikhailshilkov
I'm on that picture from Amsterdam
I found an issue which looks very simple: dotnet/corefx#16619
Viktor Hofer
@ViktorHofer
Hi Amsterdam team :)
Martijn Laarman
@Mpdreamz
Calling build.cmd yeah. This is on a clean checkout git clean -fxd and clean.cmd -all
Mikhail Shilkov
@mikhailshilkov
I can find FormattableString in src\CoreLib\System but I have no idea which project/solution I should open and also where the tests are....
Viktor Hofer
@ViktorHofer
Ok 5min
I'll switch to my laptop and will give you pointers
Martijn Laarman
@Mpdreamz
Thanks @ViktorHofer :smile:
Laurent Kempé
@laurentkempe
@ViktorHofer Thanks will try that
Viktor Hofer
@ViktorHofer
@Mpdreamz building should work fine. On which OS? Have you read the instructions and installed all prerequisites?
Martijn Laarman
@Mpdreamz
I did yeah I should have all the required prereqs for Windows
Viktor Hofer
@ViktorHofer
And you are using the visual Studio developer command prompt when calling build?
@mikhailshilkov it's inside Syste.Private.Corelib in coreclr. Have you already cloned the coreclr repo, installed all depencies as described in the instructions and built coreclr ones?
You then open coreclr/src/mscorlib/System.Private.CoreLib.sln
Mikhail Shilkov
@mikhailshilkov
@ViktorHofer ouch, I'm in corefx
Martijn Laarman
@Mpdreamz
I am on Windows Insider build. Building from CMD (it looks like the build calls into dev prompt https://github.com/dotnet/corefx/blob/master/run.cmd#L33 already)
Mikhail Shilkov
@mikhailshilkov
The issue is filed under corefx
Viktor Hofer
@ViktorHofer
Right, as we expose
Mikhail Shilkov
@mikhailshilkov
I'll clone coreclr, thank you @ViktorHofer
Viktor Hofer
@ViktorHofer
Right, as we expose it there in corefx, but the implementation is in coreclr :) The build takes quite a while...
Leonid Tsarev
@leotsarev
Completed about 20% of my issue.
Opened early PR in hope of getting early feedback while I continue
