RE: DPDK for Windows with MSVC compiler

[Tarun Badnora <tarun.badnora@clear-trail.com>]

Hello Dmitry,

Thanks for providing this information.

For better planning at our end, I like to ask couple of questions:

Is there a way to integrate DPDK module, built with clang/mingw, to our MSVC application ? 
I know both are different compilers, but in case if you are aware of a way/tweak that will be of our help.
OR 
If porting our application is the only option available then which compiler (clang or mingw) is recommended for optimal performance.

Regards,
Tarun Badnora

Hello Tarun,

DPDK does not support MSVC.
There is a very long term intention to build DPDK with MSVC (adding Omar and Daniel if they have any more comments), but for now it's only clang and MinGW-w64.
There is a significant gap in language features support from MSVC side and some issues (e.g. GCC-isms) from DPDK side.
