Port corehost to QNX7

[guesshe]

Hi,

I am trying to port the entire runtime to qnx7 platform on x64 arch. I am able to build coreclr but it won't run unless I have dotnet executable built. Any suggestions on how to build corehost for qnx?

Any suggestions on how to build corehost for qnx?

The same way as coreclr? It lives under https://github.com/dotnet/runtime/tree/master/src/installer/corehost

How about the .nuget packages downloaded for specific RID? I used this repo https://github.com/dotnet/core-setup/tree/v2.2.8, when I tried on linux, it pulls down some .nuget files for linux platform, but I don't have these files for QNX to pull down.

You may want to build it from dotnet/runtime repo. dotnet/runtime has everything together that avoids the issues with publishing and downloading packages between repos.

@jkotas Oh. Thanks! Shall I start with all subprojects or only coreclr and corehost should be enough for me?

[jkotas]

You can start src\coreclr, src\libraries\Native and corehost; and get the managed libraries from other Unix flavor.

[guesshe]

Thanks! By saying managed libraries, do you mean the .dll libraries?

[jkotas]

Right

@jkotas I tried the dotnet core 5.0.0-dev on linux and it can build a binary dotnet under artifacts directory, but when I tried to execute it, it gave me an error "A fatal error occurred. The folder [/home/<user_dir>/Github/runtime/artifacts/obj/linux-x64.Debug/cli/dotnet/host/fxr] does not exist". This is the same error when I tried the v2.2.8 version of ccorehost on linux. If I download the cli tar file and untar it, it has sub-directories host. What did I miss? Is the built dotnet directly executable or I have to do some post-processing?

[jkotas]

obj is directory for intermediate build files. It does not have the right directory layout.

Try the one under bin, e.g. artifacts/bin/testhost/netcoreapp5.0-linux-Debug-x64

@jkotas Thanks! I will try it out and let you know the progress.
