I have to use Firebird database with qt4.7.2 , msvc compiler.
For that I built ibase.pro from QT//src/plugins/sqldrivers/ibase. After changing ibase.pro files headers properly to include the headers of firebird I was able to build it properly and qsqlibase4.dll ,qsqlibase4.lib ,qsqlibased4.dll and qsqlibased4.lib were generated. However they weren't copied to QT//plugins as they should. I copied them myself anyway. But qt is not able to recognize that ibase driver plugin and informs ibase driver not found if i try to use it. I have no clue what is wrong. I was able to use the plugin successfully with msvc and mingw compilers successfully uptill the 4.6.3 version.
