Eclipse, Moc Files, Custom Build Steps

[gmat4321]

I am unable to get Eclipse to create MOC files through the IDE.

For a Header I've edited the Properties ... Resource Custom Build Step.
If I fill in just the 'Command' string the custom build step never fires.
If I fill in the 'Output file name(s)' with the xxx_moc.cpp file to be created I get a build error becuause the make file wants to compile the source before it is created from the header.

I'm setting up Eclipse the same way I setup Visual Studio 2008. In visual studio it worked as expected.

What silly thing have I done wrong??

Attached is a screen shot of my Custom Build Step

Do you use Qt Eclipse integration module? It should handle moc and uic.

[gmat4321]

QT/Eclipse integration is not available on the Mac. (yet)

...anyway the solution is to fill in the "Output file name(s)" with the name of the moc file, but make sure to point the moc file to the same location as the header. I was hoping to avoid this to keep the project 'clean'.

Then maybe you should switch to CMake? It can perform out-of-source builds and has some Eclipse integration plugin too.

I have used the same setup and the moc file is being generated.But my program crashes at connect statement.


code:
QUrl url;
url.setUrl(".......");
url.addEncodedQueryItem("hl", "en");
QNetworkAccessManager *manager = new QNetworkAccessManager(this);
connect(manager, SIGNAL(finished(QNetworkReply*)), this, SLOT(handleNetworkData(QNetworkReply*)));
manager->get(QNetworkRequest(url));
