Re: [Gumstix-users] Problem running Player on Gumstix

[BombiLee <che...@gm...>]

I have same problem when I am cross compling Player 2.1.1 for 
http://sites.google.com/site/copyartshouse/cross-compile-player2-1-1-to-openwrt-whiterussian-0-9-for-wrt54gl-with-64mb-ram-sd-serial-mod
OpenWRT Whiterussian 0.9 for my WRT54GL router  ( for control Roomba )
I finally figure how to fix it, not so pretty though. 
The reason cause " libxxx.so, not found ... libxxxx.so: undefined reference
XXXX.  " is the compiler some how can't find the .so files when doing
cross-compiling. My way to solve it is adding LD_LIBRARY_PATH to environment
variables.

How to find out what path you should add.
In /player-2.1.1 floder , search for shared library .so files ( after you do
first make create those errors )

   $ find  | grep .so.2.1.1

you should see some thing like this

./libplayerjpeg/.libs/libplayerjpeg.so.2.1.1
./libplayercore/.libs/libplayercore.so.2.1.1
./libplayercore/.libs/libplayerutils.so.2.1.1
./libplayercore/.libs/libplayererror.so.2.1.1
./client_libs/libplayerc/.libs/libplayerc.so.2.1.1
./client_libs/libplayerc++/.libs/libplayerc++.so.2.1.1
./server/libplayerdrivers/.libs/libplayerdrivers.so.2.1.1
./libplayertcp/.libs/libplayerudp.so.2.1.1
./libplayertcp/.libs/libplayertcp.so.2.1.1
./libplayerxdr/.libs/libplayerxdr.so.2.1.1

These are the path you should add into LD_LIBRARY_PATH, very very long
command.
this is mine
$ export
LD_LIBRARY_PATH=/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayercore/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayercore/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayercore/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/client_libs/libplayerc/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/client_libs/libplayerc++/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/server/libplayerdrivers/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayertcp/.libs:/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayertcp/.libs:
/home/steven/OpenWrt-SDK-Linux-i686-1/package/player-2.1.1-openwrt/libplayerxdr/.libs

if you already have LD_LIBARY_PATH, add " $LD_LIBRARY_PATH:" in the begging
then do 
   $ make clean
   $ make
you should be able to finish compile.....

good luck

ps. I am new in programming & player,too . Maybe you have better way to do
it.... Please let us know..
