Calibre 0.6.12 issue: libunrar.so: cannot restore segment prot after reloc

MykelAlvis · 09-14-2009, 11:54 PM

I can't seem to get Calibre to convert a .RAR archive. I get the following error message:

Code:

ERROR: ERROR: Unhandled exception: <b>OSError</b>:/opt/calibre/libunrar.so: cannot restore segment prot after reloc: Permission denied

Traceback (most recent call last):

What am I missing here?

I'm actually rather amazed to see "/home/kovid/build/calibre/src/calibre/" as you are not Kovid

Are you on linux? Is SElinux enabled (and do you want it to be)? Can you try running (as root)
setenforce 0
and then trying again?

The paths get hardoded in at bytecode-compile time. Do the following

I am guessing this is SELinux related, since I dont use it, hard for me to help. But try changing the ownership of /opt/calibre to your user account

sudo chown -R username:group /opt/calibre

Setting ownership did not work. It was, in fact, an SELinux issue, which I managed determine right before coming back and reading acidzebra's post.

I didn't check my very recent install where SELinux was set to enforcing by default (I failed to set the correct kickstart option). Setting to permissive (and re-labeling) allows me to open RARs with only a warning.

And yes, I AM Iron Ma...I mean, Kovid Goyal.
