I compiled GLIBC 2.10.1 using GCC 4.2.1 (host and build = i686-pc-linux-gnu). Then I copied "libc.so.6" to calibre. I got the following error.
DiskStation> /opt/calibre/calibre --help
/opt/calibre/bin/calibre: error while loading shared libraries: libc.so.6: cannot handle TLS data
What was wrong with compilation?
