Which decompiler for radare2?

#1

Hi. anyone can suggest a decompiler for r2… and how to install it! I tried to install r2ghidra-dec from r2pm and it fails. anyone have tried these plugin?

here’s the error:

Can you show me your output of apt list --installed | grep radare2 command please? I am the maintainer of radare2 for Parrot. It could be my mistake somewhere

#3

Here is my output and everything works fine for me

libradare2-3.8-dbgsym/rolling,now 3.8-parrot3 amd64 [installed]
libradare2-3.8/rolling,now 3.8-parrot3 amd64 [installed,automatic]
libradare2-common/rolling,rolling,now 3.8-parrot3 all [installed,automatic]
libradare2-dev/rolling,now 3.8-parrot3 amd64 [installed,automatic]

radare2/rolling,now 3.8-parrot3 amd64 [installed]
#4

p/s: you can give ghidra decompiler a try
r2pm install r2ghidra-dec

#5

this is my output of apt list --installed | grep radare2:

libradare2-3.8/rolling,now 3.8-parrot3 amd64 [installed,automatic]
libradare2-common/rolling,rolling,now 3.8-parrot3 all [installed,automatic]
libradare2-dev/rolling,now 3.8-parrot3 amd64 [installed,automatic]
radare2-cutter/rolling,now 1.9.0-parrot0 amd64 [installed,automatic]
radare2/rolling,now 3.8-parrot3 amd64 [installed,automatic]

but radare2 -v says:

    radare2 3.7.1 0 @ linux-x86-64 git.3.7.1
    commit: unknown build: 2019-10-10__14:43:32

it fails when I try to install r2ghidra-dec whit the error I posted above!

#6

Can you please reinstall libradare2-dev and try again?

#7

I remember it now. I typed 3.8 version for 3.6 and i decided to keep it be 3.8 and rolling it. But our build sever is having problem and it can’t be update from 3.8 release (I am packing 4.0 version)

#8

I uninstalled and then reinstalled libradare2-dev; run r2pm -i r2ghidra-dec and I had exactly the same error…

#9

Okay i have to check the whole thing. Thanks for report. I am very sorry for this issue. That is my responsibility.

#10

ah ok. do you think this is related to the r2ghidra-dec installation problem? if yes it’s ok I’ll wait for the 4.0 :slight_smile:

#11

I don’t think the version is the problem. The problem is the lib is missing or something like that. Gimme some min and if you have free time please help me try to fix the bug (please add telegram @dmknght if you can)

#12

Can you show me the output of ls -la /usr/include/libr please?>

not hurry but for the next update could you check the r2-docker script? it seems it doesn’t exist…
bash: r2-docker: command not found
thanks again! bye
