I am building from Windows 7. I use the following configuration command:

configure -developer-build -opensource -confirm-license -nomake examples -nomake tests -mp

I see the following errors at the end of configuration output:

Hello,

I am having some problems compiling Qt 5.1 in MAC OSX. I've followed all the steps from here: http://qt-project.org/wiki/Building_Qt_5_from_Git ...

But... when I called "make -j 4", after about one hour of compilling work, I've got this error:

@make[3]: *** No rule to make target /Users/paulopina/PlexusDynamics/qt5/qtbase/lib/libQt5QmlDevTools.a', needed by /Users/paulopina/PlexusDynamics/qt5/qtbase/bin/qmlmin'. Stop.

Just head into "qtdeclarative\src\qmldevtools"
and make a release and a debug before you proceed.

Hello Deus,

Hi,

Same error as PauloPina, then heading to "qtdeclarative\src\qmldevtools" and doing a "make" doesn't solve the problem. The make "has nothing to do". Only the debug lib is created, how do I create the release?

Thanks

There's no reference to a 'release' keyword in the Makefile. Here's how the whole qtbase was configured:

I've reconfigured with -debug-and-release option, but still no release rule and other errors raised.

Hi,

Can the owner of this documentation pls update the steps for running the 'configure' script on Win7+MinGW/MSys.

The correct command as pointed by 'JKSH' user is
$configure.bat -developer-build -opensource -nomake examples -nomake tests -opengl desktop

I think the wiki should mention that the build needs at least 3 GB of RAM to build WebKit.

I had to do a make without specifying '-j 4' (which "I think is serial execution":http://www.gnu.org/software/make/manual/html_node/Parallel.html) for the build to work.

Uncanny.

I'm routinely compiling various Qt versions, from 4.8 to 5.1, with make -j9 and never had an issue. Well, once :)

Maybe your "make" is outdated?

.moc/release-shared/moc_qactiongroup.cpp:16:2: error: #error “cannot be used with the include files from this version of Qt.”[/quote]It looks like you have multiple versions of Qt in your environment. Remove the older one from your PATH, clean your build tree (i.e. delete all the files that have been compiled so far), and try again.

Also, what compiler are you using? How did you configure + build Qt?

allenck · wrote on 24 May 2013, 03:43

Thanks. I checked the requirements as it pertained to environment variables but didn't check the path. Undoubtedly that is the reason as the compile seems to be working OK, so far, on another machine.

The compiler is g++ and I was using these configuration settings:
./configure -prefix $PWD/qtbase -opensource -nomake tests -system-sqlite -plugin-sql-sqlite -plugin-sql-odbc -plugin-sql-mysql -nomake demo -nomake examples
