Unable to get std::thread working

[Troy Heron]

I compiled the gcc 4.4.0 release from source and upon trying execute a simple hello world program that uses std::thread I get the following error:

./t: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by ./t)

All non c++0x aspects of gcc/stdc++ seem to work fine.

I'm sure I've likely done something silly when compiling/installing gcc...  any ideas?

Thanks

I have just installed gcc-4.4.0 and I got the libstdc++ library.

Try to do this :
./configure --disable-bootstrap --enable-languages=c++
make
make install

Most likely your program t is using the libstdc++.so which comes with
the system rather than the libstdc++.so which is part of your newly
installed gcc.  This can happen if you configured gcc with a --prefix
option.  The simple fix will be to set the LD_LIBRARY_PATH environment
variable to point to the directory holding your libstdc++.so.
