Fix

Some issues with r2ghidra--dec:

~/tools/Cutter --no-plugins

I've also had this issue when r2-retdec is installed. I either had to load cutter with no plugins or remove the plugin to get cutter working again.

enovella commented 3 years ago

I was able to make it to work by reinstalling r2ghidra-dec and rebooting my laptop.

I ran through the steps of installing https://github.com/avast/retdec-r2plugin and building the cutter plugin. After building the plugin and running make install Cutter will no longer start up and the following error is logged:

Setting PYTHONHOME = "/tmp/.mount_CutterWmruTW/usr"  for AppImage.
PYTHONHOME = "/tmp/.mount_CutterWmruTW/usr"
Setting r2 prefix = "/tmp/.mount_CutterWmruTW/usr"  for AppImage.
Setting r2 plugins dir = "/tmp/.mount_CutterWmruTW/usr/share/radare2/plugins"
: for the -W option: cl::alias must have argument name specified!
: CommandLine Error: Option 'bitcode-mdindex-threshold' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
QMutex: destroying locked mutex

So this issue may be more generically tied to the plugin system?

That is problem of conflict between retdec and most Linux graphic drivers as both of them use LLVM. That's a retdec problem not Cutter.

I guess that @enovella during reinstalling of r2ghidra-dec might haved wiped the retdec plugin.

Note you shouldn't manually install r2ghidra-dec when using Cutter Appimage as the Appimage already includes r2ghidra. And having second r2ghidra especially compiled against different r2 build is likely to cause conflicts.

Thank you for the information @karliss

I can open an issue (if one isn't already open) on the https://github.com/avast/retdec-r2plugin for tracking.
