When I compile my project, should I use Multi-threaded runtime library or Multi-threaded dll runtime library?
I use MSVC 2005.
Is it true, if I dont use Multithreaded runtime library, my application wont work on older systems?
The exe will be like 100KBs bigger (release mode).
Thanks for help
Well you only need the MT library (either version) if you actually use multiple threads in your program. If you don't, then use the single threaded library.
Link with the DLL if you want a smaller executable, and to benefit from "improvements" to the DLL which might happen over time.
Link with the .lib if you're concerned about "regressions" to the DLL which might happen over time.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Also, if you link to the dll, you may have to distribute the dll with your application.
