Compile error QSQLCIPHER driver plugin for Qt

[mrjj]

Ok, so it should have made it,
Seems like it bombs out for some reason.

Searching for
"flow control statement 'return', aborting block'"

Gives nothing.

Maybe you get lucky at qtcentre.org

Sorry, I have no clue what it dont like :(

Hi
Very hard to say from the txt file
For some reason it wont let me go back and view the actual bug report (33795)

This evening Im going to try the step-by-step in a virtual machine to see if im more lucky or get same error.

@mrjj Thank you very very much, please let me know the result

Hi
Got same result as you in step 6.
I used 5.4.0 as in tut.

After qmake which says nothing no moc file is
generated and mingw32-make fails and no qsqlcipher.dll is produced.

I then tried to create a moc by "moc.exe smain.cpp > smain.moc" and then copy that around but
either i did not hit the right directory or its not ok to create it like that. Still same error.

One should think that smain.cpp that do #include "smain.moc" should find it in same folder but
maybe I should have tried with full path to the file.

I have a feeling it is something really simple that will make us go facepalm once discovered.

@mrjj Thank you for your help and time,

what do you think, is it a bug in the qmake ?

[mrjj]

@4j1th
Np, i can see the benefit of encrypted sqlite.

Not sure it is a bug in qmake.
More likely something with the PRI/PRO file but it does seem like qmake just sort of bails out.

Im going now for a B.day but when i get home I going to try one more time. If same result it must be
an build error.

[mrjj]

Ok, did it once more after some beers and it build ?!
No errors.

I have shared the DLLs (debug/release) and the A files here:

Cheers :)

@mrjj congrats, well done

did you compile a project with this lib ?

[mrjj]

@4j1th

No I did not do the last part of the tut.
Maybe tonight.

@mrjj copied the dlls to plugin/sqldriver dir and build a test project but got an error

("QSQLITE", "QMYSQL", "QMYSQL3", "QODBC", "QODBC3", "QPSQL", "QPSQL7")

Ok so its not listed at all :(
I will try it too and let you know.

Hi, I did the rest of the tut and
it did produce an encrypted db.

but, then i tried to use the test .pro and main.cpp i got same
error "driver not loaded"

I tried to find a fix but seems not to see the new dlls.
Not even if you make a Deploy folder with all the needed files.

I think its just a path problem like here
http://stackoverflow.com/questions/14362881/qt-mysql-cant-load-plugin-driver-qlibrary-qpluginloader-successfuly-loaded-qs

But I had time to try load the DLL which works. Did not try the add path etc.

@mrjj I tried the solution, it doesn't work.

And I tried the sqlite default driver qt provided it's works perfectly.

@4j1th
Ok, very strange.
Im out of ideas why it will not load as driver.

The .a +.exe could produce a encrypted db and the dll can be loaded as DLL but
for some reason, it wont load as a sql driver.

So close and yet nothing :(
