Oracle installation accounted in the directory path

CodePudding user response:

This is my vs2015 configuration

CodePudding user response:

Library directory and add the first path in this picture, E: \... \ MSVC path,

CodePudding user response:

Oci. Lib have added to the project, to include in the linker Settings oci. Lib

CodePudding user response:

Solve the building Lord, I also encountered this problem

CodePudding user response:

Accounted must use the same compiler, see your that only vc2005 and vc2008
And oracle also does not provide the debug version of the DLL, the debug version can't use the debug version of the c/c + + library

CodePudding user response:

The landlord has to solve the problem, I also met the same problem

CodePudding user response:

Preliminary estimate you this should be a library version does not match, you download InstantClient12 version to try it, you use this tool is vc9 platform, and the platform tools is vc14 vs2015, I use vs2015 InstantClient12 configuration is successful,
