Templates: Use forward declarations to reduce compile time?

http://stackoverflow.com/questions/555330/templates-use-forward-declarations-to-reduce-compile-time

So a real working example. Here I have 2 files a.cpp and b.cpp a.cpp #include vector still need to know the interface #include.. collect2 ld returned 1 exit status No good. So we turn to b.cpp #include vector template class std vector int template void.. Well I used the linker errors . So now we compile b.cpp g fno implicit templates c b.cpp And we get b.o. Linking a.o..

library which is linked to main.o . Both main.cpp and b.cpp depend on the file containing the offending symbol off.h through.. anything that references off.h only the implementation b.cpp makes any reference to off.h . This alone had me puzzled. To.. confusion I was able to remove the reference to off.h from b.cpp and as expected it recompiled successfully. However when I added..
