Qt - Database Module in Windows 7 and Linux

giesbert

The compiler and linker of MSVS are always free. only the IDE need a license.
But what did not work with nmake? The source code of Qt is compiler independant.

How did you use nmake to build Qt? I can guarantee that it is possible, we do it at work also, (MSVS 2005 and 2008 for 32 and 64 bit).

Really? Sounds good, because that is what I must do as well.
Once I download de source, what must I do before run nmake? How must I configure the proyect?

download the MSVS2008 compiled binaries of Qt and Qt Addin. It seems it's not allowed to compile for MSVS2008 manually in OpenSource version.

But, the compiled binary havent support for database by default. Only sqLite but I need for mysql, that is why i wanted to compile sources.

It there any way to support mysql database module using the binaries?

mohsen

you might use QODBC. Then you should download mysql odbc connector from http://dev.mysql.com/downloads/connector/odbc/5.1.html

josemaria

That could be a good work around but I am interested in using the mysql native driver. It usually give me a better performance. I dont know because everything is so unnecessary complex in Windows. In linux everything seems to be better structured.

when you donwloaded Qt sources, unzip them to a folder: <QTDIR>.
Open a MSVS command prompt, go to <QTDIR>, call configure --help
then call configure with the parameters you need, there you casn specify, which DB-drives should be compiled. For some of them, you need some extra libraries (Orcale etc.).
when confige is through, you can call nmake and it builds Qt. But in between, you get go and have some coffee (or some more, it takes time). If you want to build Qt in a way, it can be statically linked, look at this wiki page (in the example, gcc is used, but static build with MSVS is nearly the same...): "BuildStaticQtForWindowsWithGccGerman":http://developer.qt.nokia.com/wiki/BuildStaticQtForWindowsWithGccGerman I'm pretty shure, gcc can also build 64 bit binaries.

If you search thge wiki, you could also find this article: "#

Building Qt Desktop for Windows with MSVC":http://developer.qt.nokia.com/wiki/Building_Qt_Desktop_for_Windows_with_MSVC

i preffer using mysql service too! but unfortunately it doesn't supported by MSVS2008 binaries

giesbert

If it's not supported by the binary packages, build it on your machine...

josemaria

good. Thanks very much to all of you that have help me. It is a pleasure staying here.

This is wrong. The (L)GPL version does not have any constraints about the compilers. Qt/Nokia does not provide prebuilt binaries, though. Nothing prevents you from compiling yourself.

@Volker:
I just remembered when i was trying to compile for VS with older versions but VS was not at the list of platforms.

It seems Qt currently provides configuration for VS on opensource version too.

giesbert

In earlier versions, the MSVS integration was not in Open source editiopns, and perhaps the MSVS configs. But is was never said, that compiler might not be used. Before 4.x (3?), k there was no open source version for windows....

with Qt 4.3, there was a "minGW version for open source for windows":http://labs.qt.nokia.com/2007/09/18/qtwindows-open-source-edition-to-support-vs-express/

As stated in that article, since 4.4 it is also open source for windows with MSVS compiler.
