Run perl from cmd.exe, not Bash terminal.

I did run the command "perl init-repository" from cmd.exe directly.

I'm trying to build source from the for new bug fix which critical for me.

I'm getting following linking error:

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:

Generating Visual Studio project files...

o for QtBootstrap, as the latter also load()s qt_module.

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.

This it the return i've got at "./configure -developer-build -opensource -nomake examples -nomake tests":

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

Hello Deus,

Thank you. I'll try it!

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

deus

make release

DerekDomino

Yes, of course I've tried it ;-) but unsuccessfully

@
$ pwd
(...)/qt-everywhere-opensource-src-5.1.0-alpha/qtdeclarative/src/qmldevtools

$ ls
Makefile qmldevtools.pro

$ make release
make: *** No rule to make target `release'. Stop.
@

There's no reference to a 'release' keyword in the Makefile. Here's how the whole qtbase was configured:
@
$ ./configure -prefix $PWD/qtbase -opensource -nomake tests
@

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

@
$ ./configure -prefix $PWD/qtbase -opensource -nomake tests -debug-and-release

$ make

I faced same problem,

check out this bug https://bugreports.qt-project.org/browse/QTBUG-30561

applying this patch resolved the issue https://codereview.qt-project.org/#patch,sidebyside,52170,1,mkspecs/features/qt_module.prf

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.

You can edit it any time.

I was getting a "runtime/CodeCache.cpp
The bug is not reproducible, so it is likely a hardware or OS problem."
error when using make -j 4.
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.

sierdzio

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?

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?
