Im trying to create a .so named libfunc.so, which compile from func.cpp.



I've been done steps below:
arm-none-linux-gnueabi-g++ -c -fPIC func.cpp
arm-none-linux-gnueabi-g++ -shared func.o -o libfunc.so



I get some errors when I try to compile executable:
arm-none-linux-gnueabi-gcc -L/usr/local/lib/func test.cpp -o test -lfunc 



lib/gcc/arm-none-linux-gnueabi/4.8.3/../../../../arm-none-linux-gnueabi/bin/ld: warning: library search path "/usr/local/lib/func" is unsafe for cross-compilation

/opt/gnutools/arm-2014.05/bin/../lib/gcc/arm-none-linux-gnueabi/4.8.3/../../../../arm-none-linux-gnueabi/bin/ld: /tmp/ccazeIay.o: undefined reference to symbol '_ZNSaIcEC1Ev@@GLIBCXX_3.4'

/opt/gnutools/arm-2014.05/bin/../arm-none-linux-gnueabi/libc/usr/lib/libstdc++.so.6: error adding symbols: DSO missing from command line


what cause those errors and how can I fix it?
