Probably doing something wrong but I'm getting mixed 64 and 32 bit binaries on linux. #10

So. The x370 chipset on ryzen is very much like asmedia stuff, and was hoping to poke it a bit in order to assist my port of coreboot to 'Asrock X370 Killer Sli/AC' (kind of in a working state; more to be done).

By issuing dotnet build I get a 64-bit ELF for AsmTool but the dlls come out as 32 bit. Attempting to run AsmTool nets me the following error:

Unhandled exception. System.BadImageFormatException: Could not load file or assembly '~/ASMTool/AsmTool/bin/Debug/net6.0/AsmTool.dll'. An attempt was made to load a program with
an incorrect format.

File name: '~/ASMTool/AsmTool/bin/Debug/net6.0/AsmTool.dll'
Aborted (core dumped)

libAsmIOLinux.so is compiled and in the directory next to AsmTool (it is also a 64-bit ELF)

I have the same issue. I used the CI dockerfile and commands, but the created artifact is unuseable.

In the CMake files, there's a line that clears the target platform but it doesn't get set again on Linux.

Theoretically

should be enough to fix it, but

@smx any idea what's going on here?

I have the same problem, any idea how to compile it properly on Linux?

EDIT: If you change the platform in AsmTool/AsmTool.csproj to <PlatformTarget>x64</PlatformTarget>, then the dotnet build command should give you 64-bit file: ./AsmTool/bin/Debug/net6.0/AsmTool.dll: PE32+ executable (console) x86-64 Mono/.Net assembly, for MS Windows.

When I run the executable now, it complains when the file libAsmIOLinux.so is not present. However, it always crashes later with this output (from valgrind):

==71853== Your program just tried to execute an instruction that Valgrind
==71853== did not recognise.  There are two possible reasons for this.
==71853== 1. Your program has a bug and erroneously jumped to a non-code

==71853== 2. The instruction is legitimate but Valgrind doesn't handle it,
==71853==    i.e. it's Valgrind's fault.  If you think this is the case or
==71853==    you are not sure, please let us know and we'll try to fix it.
==71853== Either way, Valgrind will now raise a SIGILL signal which will

How to proceed from this point? I am on Ubuntu-20.04 with kernel 5.15.153.1, my dotnet SDK version is 6.0.428.
