Compile error QSQLCIPHER driver plugin for Qt

mrjj

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

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 :)

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")

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

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.

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 :(
