Techniques to reduce template compile time

[PengYu.UT]

Hi,

One problem to use templates extensively is that it tends to take a
long time to compile. Other than changing to a different compiler, are
there any techniques to reduce the compile time?

Thanks,
Peng

I think you have to wait.

1. Precompiled headers - if your compiler supports precompiled headers, put
all template header includes into it and use it in all .cpp-s.

2. If your templates work on a limited number of types, put the actual
template definitions in .cpp files and add explicit template instantiations
for all needed types there. Might not work over dll/so boundaries.

3. Add more memory to your computer!
