I compiled boost 1.54 with gcc version 4.6.3( in 3.2.0-29-generic #46-Ubuntu ). Then, I developed my library using this boost library. Since I don't want to recompile boost every time I change my library, I added compiled static libraries of boost to my git repo.
Now, I am trying to compile my library in a different machine with different version compiler (tried with gcc 4.4 and gcc 4.7). My library compiles fine, but when it comes to linking it is printing following errors.

PS: I tried to compile with a different machine with same compiler version also. (gcc version 4.6.3 and Centos 6.4)
The C++ ABI is not guaranteed to be consistent across different compiler versions. This affects the C++ name mangling, and could cause the linker errors you are seeing. You have to use the same version of GCC for all libs.
The best would be to keep your whole system on the latest supported version of GCC. If your users really require different compilers, you can supply different versions of your library - one for each compiler you want to support.
Linking with libraries compiled with different compilers is not guaranteed to work. This is true for both static and shared/dynamic C++ libs.
Also have a look at: Unusual C++ linker error - 'Defined in discarded section'
It seems that the accepted answer to that question was also to compile all the libraries with the same version of GCC.
