Load Error for plugin "librz_ghidra_cutter.so" : "Cannot load library .../librz_ghidra_cutter.so: (core_ghidra.so: cannot open shared object file: No such file or directory)"

[rah2501]

Hi,

I've compiled both Cutter and rz-ghidra from source and from the stable branches but when I run Cutter, it reports:

Load Error for plugin "librz_ghidra_cutter.so" : "Cannot load library /home/rah/.local/share/rizin/cutter/plugins/native/librz_ghidra_cutter.so: (core_ghidra.so: cannot open shared object file: No such file or directory)"
Loaded 0 plugin(s).

The file does exist in the rz-ghidra installation directory:

rah@lotus:~$ ls -l /usr/local/stow/rz-ghidra-git/lib/rizin/plugins/core_ghidra.so
-rw-r--r-- 1 rah staff 15172184 Aug  5 20:42 /usr/local/stow/rz-ghidra-git/lib/rizin/plugins/core_ghidra.so

I configured Cutter using:

-DCMAKE_INSTALL_PREFIX=/usr/local/stow/cutter-git \
-DCUTTER_ENABLE_GRAPHVIZ=ON \
-DCUTTER_ENABLE_PYTHON=ON

and rz-ghidra using:

-DCMAKE_INSTALL_PREFIX=/usr/local/stow/rz-ghidra-git \
-DBUILD_CUTTER_PLUGIN=ON \
-DCMAKE_PREFIX_PATH=/usr/local/stow/cutter-git

I also used stow to link both installations into /usr/local and ran sudo ldconfig afterwards.

I don't believe I've done anything wrong or missed anything so this should work?

Core_ghidra.so is the rizin plugin (it is expected to be loaded dynamically by rizin), most likely you rizin can't find it because you installed cutter (and thus bundled rizin) into different prefix than rz-ghidra. Although the fact that your first error messages say /home/rah/.local/share/rizin/cutter/plugins/native/librz_ghidra_cutter.so not /usr/local/stow/rz-ghidra-git.

But in general if you are trying to be excessively clever and use non standard installation setups you are on your own.

excessively clever

O_o

As far as I know, stow is a very typical way, if not the typical way, to install software from source.

non standard installation setups

I'm not sure what you mean here, what do you mean by a "standard" installation setup?

Although the fact that your first error messages say /home/rah/.local/share/rizin/cutter/plugins/native/librz_ghidra_cutter.so not /usr/local/stow/rz-ghidra-git.

Did you miss off the end of this sentence?

I've managed to get the plugin working by installing all of rizin, Cutter and rz-ghidra into the same prefix under /usr/local/stow.

The README.md in rz-ghidra doesn't seem to make sense. It appears that it's required to install all of the projects under the same prefix but the README.md talks about setting various _PATH and _PREFIX cmake settings to different values. How can this ever work? Do the build instructions make sense to anyone? Has anyone tried following them?

There are two ways cutter and rizin search for plugins- the system folders and user home folders.
