<![CDATA[Using SQLCipher in place of SQLite]]>Hello,

I would like to use encrypted SQLite databases with Qt.
The company I work for, has been using SQLCipher with C++ Builder XE3 for almost two years (they bought a license). In this context it's pretty easy cause there's only a sqlite3.dll file to load.

We're switching from C++ Builder to Qt.
With Qt I can access SQLite database with the sqlite3 driver compiled with Qt. I tried it, it works and it's pretty easy to use.

According to the documentation it is possible to link with my own sqlite library ("How to Build the QSQLITE Plugin":http://qt-project.org/doc/qt-5.0/qtsql/sql-driver.html#qsqlite).

When we bought a SQLCipher licence we got a zip file which contains the following file:

  • sqlite3.c (SQLite Amalgamation file)
  • sqlite3.h
  • libeay32.lib
  • sqlite3.dll
  • sqlite3.lib

I tried to recompile the SQLite driver for Qt but it failed.
Here the step I followed:

  • Configure with qmake
    @qmake "INCLUDEPATH+=C:/AEProjects/SDKs/SQLCipher/binaries/" "LIBS+=-LC:/AEProjects/SDKs/SQLCipher/binaries/win32/lib -lsqlite3"@
  • build it
    @mingw32-make@

But it failed with the error : "ld.exe: cannot find -lsqlite3"

Do you think it's due to the sqlite3.lib file which might be sqlite3.a ?
In this case I will have to recompile sqlcipher with mingw-32.

I've seen those articles but I wanted to only link a specifc lib without recompiling SQLCipher.
"Building QSQLITE driver with AES-256 encryption support":http://www.qtcentre.org/wiki/index.php?title=Building_QSQLITE_driver_with_AES-256_encryption_support

"SQLCipher for Qt":http://www.wiki.crossplatform.ru/index.php/Привязка_SQLCipher_к_Qt#.D0.9E.D0.B1.D1.81.D1.83.D0.B6.D0.B4.D0.B5.D0.BD.D0.B8.D0.B5

Does anyone have an idea ?

I can't understand the error:

Are you the author of that post ? If yes then I would suggest you to add it to http://wiki.qt.io.
It is a common place for such articles.

Have a look on this link.
