radare2: symbol lookup error: /root/.local/share/radare2/plugins/core_pdd.so: undefined symbol: r_cons_strcat

[OscarAbundez23]

Everytime I try to use r2dec with any of the pdd subcommands, radare2 crashes and shows me this error radare2: symbol lookup error: /root/.local/share/radare2/plugins/core_pdd.so: undefined symbol: r_cons_strcat

[wargio]

did you rebuild the plugin?

[wargio]

@trufae did you remove r_cons_strcat ? can i use r_cons_println ?

[OscarAbundez23]

Rebuild? I don't know haha, I just installed it with r2pm -i r2dec, I don't know if it has anything to do with the fact that I am using it on a docker container

[wargio]

yes, you need to rebuild it via r2pm

[OscarAbundez23]

Ok, sorry, I didn't know that, but there is no information on the installation and usage. And sorry again but, how I rebuild that? Should I reinstall r2?

[wargio]

The installation/usage issue should be brought on r2pm/r2 itself, since this usually happens when you update r2. just try to see what r2pm -h says. probably r2pm -i r2dec should be enough to rebuild r2dec. That said, is possible that pancake has removed r_cons_strcat so i might still need to do some changes.

[OscarAbundez23]

Ooohh haha, ok, yes I had already tried to reinstall r2dec before with r2pm -i r2dec so I think maybe it needs some changes as you said

[trufae]

Yes, RCons.strcat was a very bad name, it's now RCons.print, but i decided to push few defines for backward compat and mark those apis as deprecated for r2-6.0.0, it should build now

[OscarAbundez23]

Ok, It works now, thank you very much
