I've downloaded qwt-6.0.1 and then tried to install qwt
. First i try to generate MakeFile :
qmake -spec macx-g++
this is ok. When i try to compile sources with make i get after a while
/bin/sh: /Developer/Tools/Qt/moc: No such file or directory
make: *** [moc/moc_qwt_dyngrid_layout.cpp] Error 127
From last versions ,Xcode is installed in Applications folder not in Developer ,Apple deleted this folder it can not be founded. I think here is the issue, but i do not know how to configure this, to make compile process to be successful
Can someone provide a way to install qwt on Mac ?
The commands should be run from the qwt directory where project.pro is in, not in src.
stephen-mac:qwt-6.0.1 stephenc$ qmake -spec macx-g++
stephen-mac:qwt-6.0.1 stephenc$ make

I am currently using Ubuntu 14.04 LTS.
How can I statically build Qt 4.8.5 -
https://download.qt.io/archive/qt/4.8/4.8.5/qt-everywhere-opensource-src-4.8.5.tar.gz
such that when I cmake OpenCV 2.4.13 -
https://github.com/opencv/opencv/archive/2.4.13.zip
it correctly identifies the location of Qt4 ?
When I cmake OpenCV after I have installed Qt4 in /usr/local/qt4-static/, the find_package(Qt4 REQUIRED QtCore QtGui QtTest) function call within opencv-2.4.13/cmake/OpenCVFindLibsGUI.cmake fails because it cannot find qmake. Also, upon running the qmake -query in the terminal, Ubuntu says that qmake is not installed, when it clearly in /usr/local/qt4-static/.
How should I go about this so OpenCV cmake correctly recognizes Qt4 ?
Build Qt
Extract the source-code and run ./configure && make and then sudo make install. It should create all necessary configuration to run qmake in any folder (system-wide).
Additional: create a symlink/export (use only if make install did not work for you)
You need to promote qmake to $PATH or create a symlink, but this is usually done when you run sudo make install after make in the Qt source-folder.
root:/home# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:
Symlink (permanently)
ln -s /path/to/qmake /usr/sbin/qmake
or
export (temporary)
export PATH=$PATH:/folder/of/qmake
Afterwards qmake -v is working whereever you are
root:/tmp qmake -v
QMake version 3.1
Using Qt version 5.10.1 in /usr/local/Qt-5.10.1/lib
If your project still cannot determine the location of Qt, read the pro/pri/cmake file to understand how it looks for the path.
I have the following setup (using qt 5.6.1-1):
qtbase/bin
...
qtbase/mkspecs
...
qtdeclarative/mkspecs
When trying to build qtquickcontrols I get the following error:
qmake
make
Some of the required modules (qtHaveModule(quick)) are not available.
Skipped.
I think it's because qmake is only looking for .pri files in qtbase/mkspecs. Is there an environment variable to set the mkspecs
search path?
I tried setting QMAKESPEC, QT_PLUGIN_PATH and INCLUDEPATH, but couldn't get past the error message.
Build process:
tar -xf qtbase-opensource-src-5.6.1.tar.xz && cd
./configure -prefix=qtbase/prefix

qmake PREFIX=qtdeclarative/prefix
make install
fails with write error to qtbase/prefix (it's not writeable by the build user)

If you have a properly set up Qt installation, it won't be a problem. Make sure that:
You've compiled all the modules.
You haven't moved your Qt build: it has hardcoded paths and can't be moved once built.
You should also prefer to build Qt in its own build folder, if you aren't doing it already.
qmake: could not find a Qt installation of ''
This thread was not of any help to me. qmake: could not find a Qt installation of ''.
How can I get qmake to recognize where the Qt folder is?
Right now it is installed in /opt/Qt5.1.0.
Have you installed the qt5-default ? You need to do this in addition to running the Qt supplier .run file.
sudo apt-get install qt5-default
This message shown by qtchooser app.
To setup it properly, you should make conf files in /etc/xdg/qtchooser/
for example:
$ ls -1 /etc/xdg/qtchooser/
default.conf
qt-4.8.5.conf
qt-5.1.0.conf
each file has two lines: path to bin, path to lib:
$ cat /etc/xdg/qtchooser/default.conf
/opt/Qt/4.8.5/bin
/opt/Qt/4.8.5/lib
additional info: man qtchooser
The solution for me on this problem was to specify the QT version, as this message was being generated by /usr/bin/qtchooser
So in my case, it was QT4 I was trying to use, and running:
qmake
generated the error (could not find a Qt installation of '')
qmake -qt=qt4
fixed that error though. In my case, it was a Ruby Gem trying to compile with qmake, so I couldn't get it to pass in that extra command line argument, so I instead added this to my profile
export QT_SELECT=qt4
And now QT4 runs just fine on my Ubuntu system.
For me the symlink to default.conf was missing in /usr/share/qtchooser. It wasn't enough to put it into /etc/xdg/qtchooser.
I am trying to understand 'qmake' by following this tutorial . but when I come the the following command:
qmake -o Makefile hello.pro
my command line console shows me this message:
'qmake' is not recognized as an internal or external command, operable program or batch file
I understood that qmake is part of Qt creator and thus it should be executed whenever I run it within my project's folder. so, why it is not recognized ?
In the start menu entry that was created by the installer for Qt, you should find an item that opens a command prompt with all the needed environment variables (including the PATH) already set. For my Qt 5.0.2 install using MingW, it is called "Qt 5.0.2 for Desktop (MinGW 4.7)".
On Windows, you can add path to qmake to PATH or run qmake from directory where it placed, or use absolute path.
Sorry my friend, i don´t speak English very well.
In Qt 5.10.1 I resolved this problem running the command prompt in the next path, C:\Qt\5.10.1\mingw53_32>, after you need change the directory where is the file hello.pro and run the commnand qmake -o Makefile hello.pro after you can see the makefile in the respective folder.
I've try few things but I still have this error when trying to cmake for blackfin:
CMake Error at CMakeLists.txt:116 (message):
Fatal error: QT (version >= 4.5.0) required. Cmake tries to detect QT4 by
searching for 'qmake' in your PATH.If you have QT4 installed, make sure
qmake is found in your PATH. If you compiled QT4 yourself make sure your
new qmake ist found _first_ in your PATH.
I'm trying to compile the source of musescore 0.9.5 to keep it compatible with the existing version of QT in uClinux options
What I did is to compile the uClinux kernel with QT lib so I can have the suitable embedded QT.
then I modified the Makefile of musescore to build with uclinux compilers. I've try different things so I show here the latest trial:
bfin:
mkdir build;
mkdir install; \
cd build;
cmake -DCMAKE_TOOLCHAIN_FILE=bfin.cmake -DCMAKE_VERBOSE_MAKEFILE=TRUE -\

urce-src-4.5.1/lib \

mscore;
in the CMakeLists.txt I did add:

Thanks in advance for the help,

You need to put qmake in your $PATH. If you prefer to use QT_QMAKE_EXECUTABLE it has to point to the actual qmake binary and not the directory.
That being said, MuseScore 0.9.5 is a very very old version of MuseScore, the current version is 1.1 and 1.2 is coming soon. Check http://musescore.org for more information about MuseScore and don't hesitate to contact the developers on #musescore on freenode.net or on the developer mailing list at http://musescore.org/mailing-list
