libcap.so.2 missing while updating to GLIBC_2.29

I had problem with GLIBC version while executing an exe file compiled in c.

/lib/x86_64-linux-gnu/libm.so.6: version 'GLIBC_2.29' not found

I found that I was using GLIBC_2.27. I updated to GLIBC_2.29 as mentioned the post Once I installed GLIBC_2.29, I set the library path using patchelf command like below,

patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 --set-rpath /path/to/newglibc/ myapp

Now I got a new error,

error while loading shared libraries: libcap.so.2: cannot open shared object file: No such file or directory

On checking for the file libcap.so.2 mentioned, I could see it is in the /lib/x86_64-linux-gnu/ path.

I am not sure how to set path for the libcap as I already set path to the glib.

Did I set the path in the wrong manner?. Is there anything I missed during the path setup in the above step?

NOTE : My Operating system is Ubuntu 18.01

Solution

  • I am not sure how to set path for the libcap as I already set path to the glib.

    You can set multiple RUNPATHs like so:

    patchelf --set-interpreter /path/to/newglibc/ld-linux.so.2 \
  --set-rpath /path/to/newglibc:/lib myapp
