libr_core.so: cannot open shared object file: No such file or directory

Evironment: Arch Linux (completely up to date) iaito + radare2 installed from git

How did u build r2 and how iaito? It looks like iaito should add support for —with-rpath otherwise it wont find the libs if they are in /usr/local if your system is not configured properly

I just did

./configure
make
make install

./configure, uses /usr/local as default path for installation, if your system doesnt have this path in the library path (etc/ld.so.conf and LD_LIBRARY_PATH env var), then the program needs to be compiled with rpath in order to find the libraries in there.

Using rpath is a bad practice because it limits the ability to the user to tell the system where the libs are. So its not done by default, as long as all distros will complain if so.

git pull, i just pushed a "fix" for make run to inherit the ldpath from r2, so it will work for your case, but will fail again when installed because no rpath or ld.so.conf

Ok, thanks

[VolkerSchlegel]

I tried adding /usr/local to /etc/ld.so.conf and then running ldconfig, but it still can't find it.

[trufae]

The path is /usr/local/lib

[VolkerSchlegel]

Oh.

[VolkerSchlegel]

Ok, it finds the shared object now
