Thanks everybody for inputs. Now I'll return to my original question.
Linking by gcc is done in such a way that library names are stored with
their version number intact. What I mean is that say I build a program
test.cpp with gcc.
On doing ldd, I get the following output,
ldd ./a.out
libstdc++.so.5 => /usr/local/lib/libstdc++.so.5 (0x40014000)
libm.so.6 => /lib/i686/libm.so.6 (0x400dc000)
libgcc_s.so.1 => /usr/local/lib/libgcc_s.so.1 (0x400fe000)
libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
This means that the end machine should have libstdc++.so.5. Generally my
experience with other machines is such that one links against the
un-versioned library name:
libstdc++.so
That name will be a link to a specific version of the library:
libstdc++.so -> libstdc++.so.4 or libstdc++.so -> libstdc++.so.5
But that is not the case on Linux.
What I wonder is that how shared libraries are versioned on Linux?
thanks in Advance
Ajay
