打开工程：
C:\Qt\4.8.1\src\plugins\sqldrivers\oci
修改oci.pro：
TARGET = qsqloci
SOURCES = main.cpp
include(../../../sql/drivers/oci/qsql_oci.pri)
include(../qsqldriverbase.pri)
INCLUDEPATH += D:\oracle2\product\11.2.0\dbhome_1\OCI\include
LIBPATH += D:\oracle2\product\11.2.0\dbhome_1\OCI\lib\MSVC
编译完成后，拷贝库文件到：
C:\Qt\4.8.1\plugins\sqldrivers
qsqloci4.lib
qsqlocid4.lib
qsqloci4.dll
qsqlocid4.dll
Linux下编译Oracle驱动
打开工程：
/usr/local/qt-4.5.2/src/plugins/sqldrivers/oci
HEADERS = ../../../sql/drivers/oci/qsql_oci.h
SOURCES = main.cpp \
../../../sql/drivers/oci/qsql_oci.cpp
LIBPATH += /u01/app/oracle/lib
win32:LIBS *= -loci
unix:!contains( LIBS, .*clnts.* ):LIBS *= -lclntsh
macx:QMAKE_LFLAGS += -Wl,-flat_namespace,-U,_environ
include(../qsqldriverbase.pri)
编译完成后拷贝到相应目录。
