Obviously I am missing something. Here are the commands I use to compile
and link:
gcc -Wall -fpic -c -o./miscfuncs.o ./miscfuncs.cpp
ld -G ./miscfuncs.o -Bsymbolic -lc -lm -o ./edbutil.so

the result is missing dependency to libstd++

If I make a program instead of library and compile with g++ - everything
is OK.
So the question is: How to compile and link my library? It is a couple
of files in different directories.
