Ghidra Decompiler Error: No print languages registered

Describe the issue

unable to emulate riscv

How to reproduce?

1. install plugin r2pm -ci r2ghidra
2. check support for emulation rasm2 -L (shows _dAe ... r2ghidra)
3. compile a c file using riscv64-linux-gnu-gcc hello-world.c -o hello-world or even clang --target=riscv64 -march=rv64gc -c hello-world.c (linking appears to have issues on clang)

try to emulate

r2 -a r2ghidra -e asm.cpu=riscv hello-world

goto asm page

see error

Expected behavior

radare2 opens file and can step through assembly via ESIL

I am running Kali Linux in WSL, and for some reason I can’t install r2ghidra. It compiles fine, but then the installation fails with this message:

: Leaving directory '/home/kali/.local/share/radare2/r2pm/git/r2ghidra/src' gmake: Entering directory '/home/kali/.local/share/radare2/r2pm/git/r2ghidra/src' mkdir -p mkdir: missing operand Try 'mkdir --help' for more information. gmake: *** [Makefile:86: install] Error 1 gmake: Leaving directory '/home/kali/.local/share/radare2/r2pm/git/r2ghidra/src'

I think this might be because line 83 in src/Makefile, PLUGDIR?=$(R2_LIBR_PLUGINS) doesn’t work for some reason, it looked like PLUGDIR is set to nothing.

Any ideas?

With radare2 fresh compile from git source on Ubuntu 20.04.2 LTS and installing r2ghidra the recommended way... ($ r2pm -ci r2ghidra):

using pdg returns "Ghidra Decompiler Error: No print languages registered"

and running pdgs returns "No languages available, make sure r2ghidra.sleighhome is set correctly!"

Now I have not done much research on Ghidra yet, but although the README specifically says that this is standalone, something tells me that I am missing files from Ghidra. Have I misunderstood the README for r2ghidra and expected to already have Ghidra set up?

Thanks.

I can upload the whole build log, but don't know where to attach it.

It seems that the meson build system is lacking some instructions. Its not installing a single file:

Expected files:

• all the /usr/lib/radare2/$version/r2ghidra_sleigh sleigh as well as the .so

==> Starting package()...
ninja: Entering directory `build'

its called like this:

  --sbindir       bin \

i installed r2ghidra using those commands r2pm update r2pm -i r2ghidra it then downloaded, compiled and installed everything, but when a try and actually use it it says this Ghidra Decompiler Error: No sleigh specification for PowerPC:BE:32:default what can i do to fix this thxs

Hi, first of all, thanks for this build. you are doing great. but I am running with an issue regarding the installation of ghindra plugin. I installed radare2 latest version from windows installer and for plugin as per instruction i unzip it in radare directory but when i try to decode a function, i came up with following error

Would be nice to have such ability as an option in upstream.

Right now it is only possible to do that using the following commands:

make -C ghidra sleigh-build
export R2_LIBR_PLUGINS=$(r2 -H R2_LIBR_PLUGINS)
DESTDIR="${pkgdir}" make -C ghidra install
