"Decompilation is not properly configured" but it actually is about retdec-idaplugin

[PeterMatula]

Yes, it seems you are doing everything right - so it it hard to say, what is wrong. Lets try two things:

1. Can you try it with some binary that does not use custom IDA loader? This should not cause the described problem, but who knows. Just try it with as simple binary as possible.
2. If it still does not work (probable), can you try running RetDec from cmd.exe the same way the plugin does (it uses sh)?
   sh retdec-decompiler.sh --help
sh retdec-decompiler.sh simple-binary.exe

1. Using a simple binary (32-bit Windows DLL) in IDA also fails with the same problem (but I don't get the custom loader warning)
2. From cmd.exe it works but I just used retdec-decompiler.sh simple-binary.dll instead of the prepended sh since the sh command is not installed and it doesn't seem to be needed though.

With win-bash:

>C:\shell\sh.exe retdec-decompiler.sh simple-binary.dll
C:\Users\User\AppData\Local\Temp\191776.201428.inc.sh2: readlink: command not found
retdec-decompiler.sh: ./retdec-utils.sh: No such file or directory
retdec-decompiler.sh: syntax error near unexpected token `<<<'
retdec-decompiler.sh: retdec-decompiler.sh: line 184: `                 IFS='-' read -a vs <<< "$r"  # parser line into array'

I might be doing the later wrong but since I'm running Windows, readlink doesn't exist (it's a Linux command). Also I'm not sure why the IDA plugin uses sh when it works from cmd.exe without it.

I am facing the exactly same issue as outlined in the 1st post.
(Windows 10/64, most recent IDA Pro, retdec and plugin, following all instructions from the Github pages)

C:\Users\Michael>sh retdec-decompiler.sh test.exe /c/retdec/bin/retdec-decompiler.sh: line 23: ./retdec-utils.sh: No such file or directory

C:\Users\Michael>bash retdec-decompiler.sh test.exe /c/retdec/bin/retdec-decompiler.sh: line 23: ./retdec-utils.sh: No such file or directory /c/retdec/bin/retdec-decompiler.sh: line 169: get_realpath: command not found /c/retdec/bin/retdec-decompiler.sh: line 170: get_realpath: command not found

I think the problem is the missing sh (i.e. missing MSYS2). Right now, it is a bit tricky to set up everything correctly. Section 2.2 of plugin's user guide says you need a properly installed standalone RetDec. The instructions to follow say to install and configure MSYS2 on Windows. Then, you should have both sh and readlink (and a bunch of other stuff).

Standalone RetDec might be working on your system even without MSYS2, but it does not on all Windows systems. That is why the plugin is explicitly calling sh (MSYS2) at the moment. If the MSYS2 is installed and in the path, it should work for all.

Try to install MSYS2.

There is already a pull request that rewrites all bash scripts to Python. Once this is finalized and merged, the whole process should be much simpler - no MSYS, only Python. We will definitely create a new release, maybe even an all in one that contains both RetDec and plugin and will not need to be configured much (at all?).

Thanks for your reply.
Not sure if I understand correctly, but when I use 'MSYS2' a MSYS-shell opens.
C:\msys64\mingw64\bin;C:\msys64;C:\msys64\usr\bin; are included in my path.

After installing MYS2 and adding C:\msys64\usr\bin;C:\msys64;C:\msys64\usr\bin to the PATH it works now for me now. I also agree that Python would be better.
