i tried r2 with option -a riscv -c"pdg"
got a message: "Ghidra Decompiler Error: Could not match asm.arch riscv to sleigh arch."

R2 version is 5.5.0-w64. works perfectly with 8051.
what's the recipe for riscv?

trufae commented

I will do my best ;)
Does your experience cover the w64 version?

trufae commented

Of course. I do maintain everything

Last "fresh" 5.8.2 is working fine until core_r2ghidra.dll placed to lib\plugins

radare2-5.8.2-w64\bin\radare2.exe "Debug Assertion Failed"

trufae commented

Use r2-5.8.4. Why are you using an old r2?

5.8.2 is last release of r2ghidra. isn't it?

I foresee the following question..
core_r2ghidra.dll (5.8.2) placed to to lib\plugins of radare2-5.8.4-w64 produce exactly same exception as above.

trufae commented

Which windows are you using? It works fine for me on windows 11

Win10

do you need something else ?

Time. Cant catch up with all the projects i maintain 24/7. I will try to repro and see what i can do. Probably its an issue with the flags passed to msvc but i need to find time to take a look because without reproducing it its harder to guess wheres the issue

Sincere thanks for your efforts!
..unfortunately I'm not the one who can give you time, it's not in my power :)

@trufae, May this case be reopened?

trufae commented

Maybe worth reopening and updating the title to clarify it's just affecting windows
