Missing src/Tools/CoreFx.Tools for an x86 Linux Build

[philippweidhas]

Hallo Community,
Maybe im here right for following problem.
Im facing following problems building the build-managed.sh for an corefx x86 build:

/home/arbeit/Tools/depProj.targets(83,5): error : Error no assets were resolved from NuGet packages. [/home/arbeit/corefx/external/netstandard/netstandard.depproj]
/home/arbeit/Tools/depProj.targets(83,5): error : Error no assets were resolved from NuGet packages. [/home/arbeit/corefx/external/docs/docs.depproj]
/home/arbeit/Tools/depProj.targets(83,5): error : Error no assets were resolved from NuGet packages. [/home/arbeit/corefx/external/ILLink/ILLink.depproj]

I was following these steps:

git clone https://github.com/dotnet/corefx.git
cd corefx
sudo ./cross/build-rootfs.sh x86

./build-native.sh -debug -- clang3.8
./build-native.sh -debug -buildArch=x86 -- cross clang3.8
./build-managed.sh -BuildTests=false

The build-native.sh builds working fine, but the managed build not. I also tried -release instead of -debug.

I found these issue with a workaround but i have no
src/Tools/CoreFx.Tools/CoreFx.Tools.csproj.

Can someone help me with that problems?

Greetings

Philipp.
