PKG_CONFIG_PATH doesn't stop the make from trying to use old version of libtorrent

[nullstring@terra.chuui.jp]

I don't exactly understand how all of this works as of yet, so bear with me.

Problem: when trying to compile and install libtorrent and rtorrent with a prefix. rtorrent still wants to be compiled using the version of libtorrent found in /usr/local/lib.

Quick Fix: uninstall current version of libtorrent temporarily

Here is an example:

circumstances-

• rtorrent 0.7.7 and libtorrent 0.11.7 currently installed
  
• compiling rtorrent 0.7.9:
  • libtorrent 0.11.9 installed at /home/byan/rtorrent (using prefix with ./configure)
  • export PKG_CONFIG_PATH=/home/byan/rtorrent/lib/pkgconfig
    
  • ./configure prefix=/home/byan/rtorrent
    
    • configure works

make fails because it wants to use the wrong version of libtorrent

Try make DEFS=-L/home/byan/rtorrent/lib

[nullstring@terra.chuui.jp]

make DEFS=-L/home/byan/rtorrent/lib did not work.

Try LD_LIBRARY_PATH=/home/byan/rtorrent/lib Or DYLD_LIBRARY_PATH=/home/byan/rtorrent/lib (if on OSX or BSD I think)

I have the same problem and the above solutions didn't work

If you have this problem, it means the linker is trying to link in an old version of the library. Try uninstalling any old version you have first.

Also I think the configure option to use is "LDFLAGS=-L/home/byan/rtorrent/lib". Or wherever you installed libtorrent.
