The command I used are :

set INCLUDE=%INCLUDE%;C:\oraclexe\app\oracle\product\11.2.0\server\oci\include
set LIB=%LIB%;C:\oraclexe\app\oracle\product\11.2.0\server\oci\lib\MSVC
cd C:\Qt\qt-5.4.0-x64-msvc2012-compact\qt-everywhere-opensource-src-5.4.0\qtbase\src\plugins\sqldrivers\oci
qmake oci.pro
nmake

set INCLUDE=%INCLUDE%;C:\oraclexe\app\oracle\product\11.2.0\server\oci\include
set LIB=%LIB%;C:\oraclexe\app\oracle\product\11.2.0\server\oci\lib\MSVC
cd C:\Qt\qt-5.4.0-x64-msvc2012-compact\qt-everywhere-opensource-src-5.4.0\qtbase\src\plugins\sqldrivers\oci
qmake oci.pro
nmake

I've many searched in the Net and tried some manipulation but I've not understund what is my problem.

Can anyone help to resolve this problem.

Many thank in advance.

It appears that the necessary libraries to run the linker are not present. Have you established the correct command line environment for your version of MSVC?

And make sure you are linking to 64-bit libraries, not 32-bit ones. Also make sure that your compilation sets the 64-bit flag so you really are compiling 64-bit code (don't remember what it is offhand).
