How to build on Linux?

[Jfk-re]

Hello,

I'm trying to build Reko on Debian Bullseye. I have .NET SDK 5.0 installed.

I have been trying to build Reko according to the docs with:

msbuild /p:Configuration=UnixRelease /p:Platform=x64 src/Reko-decompiler.sln

(.NET 5 on Linux doesn't seem to include msbuild, so msbuild from Mono is used) That results in a long list of missing dependencies:

Project "/home/ghidra/reko/src/Reko-decompiler.sln" (1) is building "/home/ghidra/reko/src/Core/Core.csproj" (2) on node 1 (default targets). /usr/lib/mono/msbuild/Current/bin/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets(234,5): error NETSDK1004: Assets file '/home/ghidra/reko/src/Core/obj/project.assets.json' not found. Run a NuGet package restore to generate this file. [/home/ghidra/reko/src/Core/Core.csproj] Done Building Project "/home/ghidra/reko/src/Core/Core.csproj" (default targets) -- FAILED. Project "/home/ghidra/reko/src/Reko-decompiler.sln" (1) is building "/home/ghidra/reko/src/Decompiler/Decompiler.csproj" (3) on node 1 (default targets). /usr/lib/mono/msbuild/Current/bin/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets(234,5): error NETSDK1004: Assets file '/home/ghidra/reko/src/Decompiler/obj/project.assets.json' not found. Run a NuGet package restore to generate this file. [/home/ghidra/reko/src/Decompiler/Decompiler.csproj] Done Building Project "/home/ghidra/reko/src/Decompiler/Decompiler.csproj" (default targets) -- FAILED. ... (110 errors in total)

I subsequently tried to build using 'dotnet build' from .NET 5:

dotnet build --configuration UnixRelease src/Reko-decompiler.sln

Now, I'm getting errors that build is only supported on Windows:

... (and so on)

As I'm not particularly experienced with building .NET projects, could anyone point me in the right direction as to how to build reko on Linux?

Thanks in advance!

Strange that msbuild didn't do a restore for you. You can try issuing the dotnet restore command in the src directory before issuing the msbuild command. Let me know if that helps.
