The error is quite clear: “ The C compiler "/usr/bin/cc"is not able to compile a simple test program.”

so you dont have a compiler or any of their basic dependencies/libraries like libgcc or libc. You may need to install

according to google the pkg name you have to install is named “build-essential”.

also, theres a deb pkg for the r2ghidra decompiler in the release page iirc. You can also install it from there (hasnt been tested)

also if u installed r2-5.2.1 from the rwlease page of r2 you will need the -dev one too

Thx for your help , the problem was not the compiler it seems , but not having installed the dev deb package.
I have removed all versions and dependencies from my installation and reinstalled the r2 5.2.1 versions (with dev package)

after doing the r2pm -ci r2ghidra i still get following errors :

Module version mismatch /home/mint/.local/share/radare2/plugins/core_pdd.so (4.2.1) vs (5.2.1)
Module version mismatch /home/mint/.local/share/radare2/plugins/core_pdd.so (4.2.1) vs (5.2.1)

Those are warnings. Not errors. And it can he fixed by recompiling the r2dec plugin. r2pm -ci r2dec

[linxcow]

it worked thank you
