problems building TGE proyect: undefined reference to `dStrstr

I get this error:

I saw a similar error <a href="http://www.garagegames.com/community/forums/viewthread/80939">here</a> and i thougt it could be due to the same reason, so I'm using an old version of gcc:

If I do: "gcc -v" I get:

Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.2.0/configure --prefix=/opt/gcc-4.2.0 --enable-shared --enable-languages=c,c++ --enable-threads=posix
Thread model: posix
gcc version 4.2.0


And even though it still gives me the same error as when i was using gcc-4.4

Anyone has an answer?
