[Dbbalancer-users] Re: Building static binary

[Daniel V. S. <dv...@ar...>]

That's curious.

The missing symbols are from librt. My dynamic binary links to it, as libACE 
does. But my static builds doesn't seem to need it, even being those symbols 
undefined in my libACE.a. I suppose that the ACE functionality that needs 
librt isn't being used, but your compiler complains anyway.

I suppose that a good solution is to add -lrt to the static build line. It 
doesn't hurt my build, anyway. I've added it to next version.

Regards
