Static compile error Qt5.12.0: bootstrap-private

[dalishi]

Hi, I try to compile Qt5.12.0 into static lib using the following commands:

$ mkdir qt5.12.0-static-build
$ cd qt5.12.0-static-build
$ ~/Qt/5.12.0/Src/configure -static -prefix ~/qt5.12.0-static-build -fontconfig -nomake tests -nomake examples
$ make 

Error:

make[3]: Leaving directory '/home/desaysv-zq/qt5.12.0-static-build/qtbase/src/tools/bootstrap'
cd tools/moc/ && ( test -e Makefile || /home/desaysv-zq/qt5.12.0-static-build/qtbase/bin/qmake -o Makefile /home/desaysv-zq/Qt/5.12.0/Src/qtbase/src/tools/moc/moc.pro ) && make -f Makefile

I'm running on Ubuntu16.04.

Any help?

Hi,

Did you download the sources using the MaintenanceTool ?

[dalishi]

I downloaded the source using qt-unified-linux-x64-3.0.6-online.run.

Btw, deleting the -prefix option in configure works just fine. Weird.

[Taytoo]

@dalishi Were you able to solve it? I've run into same issue. I'm trying on windows though.

[SGaist]

@Taytoo, @dalishi removed the prefix option from its configure options.

[Taytoo]

@SGaist But then it will install Qt to "C:\Qt\Qt-5.12.0", instead of my preference "C:\Qt\Static\5.12.0"?

[SGaist]

You asked what @dalishi did, I didn't say it would be the best solution. As for the default prefix used, I don't currently know.

@Taytoo Hi Sorry i didnot see your message. I cannot remember what I have tried last time but I do remember sometimes you need to run the configure from /Src otherwise certain modules cannot be found. But this might not be the case for your Qt version. I'm not sure about Windows. I can only list the steps that worked for me fyi. I also found this tutorial quite useful. It also talks about windows and most important with troubleshootings.

For my case, Qt 5.12.0 on Ubuntu16.04.3.

1. Install Qt from online installer in the standard way. Now you have your Qt in a home folder.
2. Build static Qt libraries:

$ mkdir ~/qt5-static-build  // where you want to put your static Qt libs
$ cd ~/qt5-static-build       
$ mkdir build               // prefer shadow build
$ mkdir install             // where you want to install your static Qt libs
$ cd build
$ ~/Qt/5.12.0/Src/configure -static -release -prefix /path-to/qt5-static-build/install -skip webengine -nomake tests -nomake examples
$ make -j8
$ make install              // Compiled static Qt libs will be installed /path-to/qt5-static-build/install

3. Link you application to static Qt libs

$ cd app-source-code/         // Usually this is your Qt project folder
$ mkdir static-build          // Shadow build for your app
$ cd static-build 
~/qt5-static-build/install/bin/qmake -config release ..   // Just make sure the qmake you used is the one we installed in Step 2
$ make

This works for me though and hope this helps. Cheeers.

@SGaist Hi think this topic can be closed as resolved.

This happened to me when I - the same as you - tried to build and install in the same directory. IOW if the -prefix pointed to the directory I issued the configure from. After separating build and install directories the error didn't show up anymore.

Hi , I try to compile Qt5.7.0 on ubuntu 20.04 for cross compilation platform, using following command:

./configure -release -prefix /usr/local/Qt-5.7.0 -opensource -confirm-license -nomake examples -fontconfig -skip qtwayland -skip qt3d -skip qtactiveqt -skip qtandroidextras -skip canvas3d
-skip qtgamepad -skip qtlocation -skip qtmacextras -skip qtwebchannel -skip qtwebengine -skip qtwebsockets -skip qtwebview -skip qtwinextras -skip qtdatavis3d -skip qtconnectivity
-no-openssl -skip qtdeclarative -qreal float -skip qttools

Error :

Project ERROR: Unknown module(s) in QT: bootstrap-private
make[1]: *** [Makefile:114: sub-rcc-make_first] Error 3
make[1]: *** Waiting for unfinished jobs....
Project ERROR: Unknown module(s) in QT: bootstrap-private

Any help?

@ananomous
Since you are compiling static [I think that is relevant, but anyway] did you look at https://bugreports.qt.io/browse/QTBUG-71540 ? Is that somehow relevant to your 5.7? Actually I'm not sure it is, I don't you're using -prefix, but worth a look anyway, maybe you need to?

[ananomous]

@JonB
I try without prefix but having same results.

[JonB]

@ananomous
If you say so. It seems to me that post says you do need it, just set to something different. But you probably know best.

1. Do Not run configure directly in the src directory (e.g., run ./configure), run it in a separate build directory.
2. Make sure your -prefix "install/path" is different from your build directory, otherwise you will encounter this issue.

The typical steps to build Qt

$ mkdir build
$ cd build
$ ~/your/qt/src/configure -prefix "~/your/qt/install/path" -other-options...
$ make
$ make install

Your

1. source directory
2. build directory (your pwd)
3. install directory (assigned with -prefix)

must be 3 different directories.
