hello,
i could resolve same problem by attachinging the "oraprovider140.lib" to the following parts of .cbproj-file:
<LinkPackageStatics>
...System.lib;unidac140.lib;dac140.lib
and
<AllPackageLibs>
System.lib;unidac140.lib;dac140.lib
UNIDAC
Re: UNIDAC
Starting from the next version, we will ship required *.OBJ files, therefore you won't have to manually add *.lib files.
