BUG: Ghidra Decompiler Error: No print languages registered

[srobertjames]

I recently cleaned out and fresh installed radare2, and now get this error:

[0x00001060]> s main
[0x00001159]> pdg
Ghidra Decompiler Error: No print languages registered

I tried with multiple binaries. r2 installed from git:

$ r2pm -l
r2book
r2frida
r2ghidra
r2ghidra-sleigh

$ r2 -V

    Fix #18621 - Specify ABI version to be X.Y instead of X.Y.Z ##build
    
    * Installation creates some more symlinks now

Can you comment on this? If for some reason you consider this a non-issue, please state so (and why).

I cant repro and i tried on mac and linux on latest git and previous build too.

Can you confirm you did

r2pm -ci r2ghidra
r2pm -ci r2ghidra-sleigh

?

[srobertjames]

Thank you, the "-ci" fixed it. The only thing I can think that caused it is that I first installed r2ghidra (and other plugins), tried running it, then installed r2ghidra-sleigh. Perhaps splitting them (with other plugins in between) broke something.
