DaoPointer build error w/QT5.0.1 on OS X

[mjbraun]

(I'm brushing off my C++ skills, so apologies if I overlooked an obvious answer.)

I'm running into compile errors with QxORM 1.2.4 using QT5.0.1 (clang 64bit) on OS X Mountain Lion (1.8.2) with Boost 1.53.0 installed via Homebrew. Compiling (within Creator and from the command line) give the same errors:

I also pulled down the 1.2.5_BETA_08 I came across while looking for a resolution, but the problem remains. Any suggestions for what I might be doing wrong? I appreciate any assistance!

Hi,

With Qt5, you must use the last BETA version : QxOrm_1.2.5_BETA_08.
You can download it here : http://www.qxorm.com/version/QxOrm_1.2.5_BETA_08.zip

You are compiling with clang : sorry, but clang has not been tested yet with QxOrm library.
On MacOSX, you have to use GCC.

[mjbraun]

It's GCCthen: as I mentioned, I had previously tried 1.2.5 BETA 8. However, I can't for the life of me figure out how to cleanly build QT everywhere with GCC so that I have the new toolchain set up (and recognizable in QT Creator, ideally). I have GCC 4.2 (also via macports), I've pulled all the links to llvm out of /usr/bin and replaced them with links to GCC/G++ but it seems that ./configure is "clang-ing" everything still.

Forgive the ignorance, as I'm sure I'm missing something. Also, thank you for your response!

[qxorm]

I don't understand what do you want exactly !
QxOrm library works fine on MacOSX using GCC : to configure your Mac, sorry I can't help you !
You should try to find a Mac developper forum to help you to install your dev environment with GCC.

[mjbraun]

I don't understand what do you want exactly !

It's seeming like that may be both of us!

No worries: Qt5 is still "fresh out of the oven", so I'll stick with the DB functionality it provides for now until it's matured a bit more. Thank you very much for the help!

[qxorm]

As I said, your problem comes from your compiler : clang has not been tested yet with QxOrm library.
But if you have some time, I would appreciate if you could test and validate clang compiler.
To fix your first compilation error, just follow those steps :
1- go to ./include/QxDao/ directory of your QxOrm package ;
2- open QxDaoPointer.h file (it is where you have your error) ;
3- replace lines from 175 to 177 by those lines :

Code: Select all

   template <class X> qx::dao::ptr<X> staticCast() const       { return qx::dao::ptr<X>(m_pWork.template staticCast<X>(), m_pOriginal.template staticCast<X>()); }
   template <class X> qx::dao::ptr<X> dynamicCast() const      { return qx::dao::ptr<X>(m_pWork.template dynamicCast<X>(), m_pOriginal.template dynamicCast<X>()); }
   template <class X> qx::dao::ptr<X> constCast() const        { return qx::dao::ptr<X>(m_pWork.template constCast<X>(), m_pOriginal.template constCast<X>()); }

I think it will fix your compilation errors on this file, but maybe you will have some other errors on other files, we will see...
I have tested and this fix doesn't break compilation on MSVC2008 on Windows, so for me it's ok, I will include this path on the next release...

[mjbraun]

Yep, that fixed the error. Thanks!

Note that the build did fail out later on, however (FYI):

Please, with Qt5, don't try to compile with QxOrm 1.2.4 : you have to use QxOrm 1.2.5 BETA 08 !
toAscii() and fromAscii() functions are noted "deprecated" in Qt5 documentation : so I have removed them in QxOrm 1.2.5 BETA 08.
