error while loading shared libraries: libstdc++.so.5: cannot open shared object file: No such file or directory.
install the following package libstdcxx5-compat_5.0.7_armv5tel.ipk
in RC11 the libstdc++ are the .6, the package name is misleading.
You need the .5 version to run C++ applications compiled for 1.10 rc5 to rc10
Note: this info has been allready given in various threads, if you allready have installed a .5 version you don't need this ipk, i just packaged the libs in an ipk.
