LD_LIBRARY_PATH needed for gcc-3.4.5 executable

LD_LIBRARY_PATH needed for gcc-3.4.5 executable

[David M. O'Brien]

Can anyone suggest a fix for this??


I am compiling a program with gcc-3.4.5 g++.
When I go to execute that program I get the following:

ld.so.1: ./prog1: fatal: libstdc++.so.6: open failed: No such file or directory

I can solve the issue by setting my LD_LIBRARY_PATH to the directory where
libstdc++.so.6 is located.

This program used to run with gcc-2.95.3 without resetting LD_LIBRARY_PATH.

Question I have,

Is there a way to compile my program so that there is no need to have the
libstdc++.so.6 at runtime? Can I create a prog1, that contains all symbols and
no need for this library when executing?

If so, what are the command options for doing that? I have read over the g++ and
ld documentation but can not seem to find the correct combination.

Thanks,
Dave

hi Dave ,
You can link it statically if you are ready to have a huge executable,
if you do  that then Dynamic Linking would not be needed at all ,all
the linking would be built inside the executable
I think -static is the switch to do that

Static linkage is problematic on GNU/Linux and similar systems.  If
you must link statically with libstdc++, it's probably better to link
statically only with that library.

You can do that with something like:

  gcc test.cc -Wl,-Bstatic -lstdc++ -Wl,-Bdynamic

but in general we don't recommend static linkage at all.
