I've recently moved from Fedora to Centos6 and woudl love to get qbittorrent back. However, it's not available in the repos so I'm trying to build from scratch.

So far, the libtorrent-rasterbar-0.16.15 will not build as it has a bug and won't recognise the libboost so have installed libtorrent-rasterbar-0.16.12

[root@localhost qbittorrent-3.1.9]# find / -name libtorrent-rasterbar.so.7
/usr/lib/libtorrent-rasterbar.so.7
/usr/src/libtorrent-rasterbar-0.16.12/src/.libs/libtorrent-rasterbar.so.7
[root@localhost qbittorrent-3.1.9]# rpm -qa | grep libtorrent
libtorrent-0.13.2-1.el6.rf.x86_64

I've then built qbittorrent-3.1.3 which built ok,

[root@localhost qbittorrent-3.1.9]# ./configure

Good, your configure finished. Now run /usr/bin/gmake.

[root@localhost qbittorrent-3.1.9]# /usr/bin/gmake

install -m 755 -p "qbittorrent" "/usr/local/bin/qbittorrent"
make[1]: Leaving directory `/usr/src/qbittorrent-3.1.9/src'

But when I attempt to execute qbit I get:

[root@localhost qbittorrent-3.1.9]# /usr/local/bin/qbittorrent
/usr/local/bin/qbittorrent: error while loading shared libraries: libtorrent-rasterbar.so.7: cannot open shared object file: No such file or directory

Any ideas?

Locate your 'qbittorrent' binary, cd to it and issue "ldd qbittorrent"
The entry for libtorrent-rasterbar.so.7 does it point somewhere? Does it point to the path where you installed libtorrent?

libtorrent-rasterbar.so.7 => not found

Could I have make a mistake in building it or libtorrent?

SOLVED. (I hope)
Was looking at the output of the ldd command and thenit hit me - there are all lib64 libraries, and libtorrent is in /usr/lib/ not /usr/lib64 so put a softlink in and bingo.
