Re: [Cppcms-users] Boost locale with icu backend static linking.

[Stanimir M. <sta...@zo...>]

I knew that i am doing something wrong, but after I read some
explanations for linking with static and dynamic libraries, and after
several reordering was not able to do it.
Thank you for this help and for the additional good tips for linking.
