Good Morning,
I am currently trying to build a project in QT that uses the Qwt library. However, when I try to build the project I get
warning: directory not found for option '-F/usr/local/qwt-6.1.0/lib'
error:framework not found qwt
error:linker command failed with exit code 1
I have followed the steps in this post as well as this post but it still cannot find the framework
I am using Xcode 6, Qwt 6, QT 5.3, and Mac OSX 10.9.
My .pro file's relevant code is as follows:
#mac: QMAKE_MAC_SDK.macosx.path = Applications/Xcode.app/Contents/Developer/Patforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
#mac: QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.9 #Added to help build QWT
#INCLUDEPATH += /usr/local/qwt-6.1.0/qwt.prf
include (/usr/local/qwt-6.1.0/qwt.prf )
#CONFIG += qwt
#macx:QMAKE_MAC_SDK += macosx10.9
QMAKEFEATURES += /usr/local/qwt-6.1.0/features
CONFIG += qwt
#mac:INCLUDEPATH += /Library/Frameworks/qwt.framework/Headers
#mac: INCLUDEPATH += /usr/local/qwt-6.1.0/src

linux-g++:INCLUDEPATH += /usr/local/qwt-5.2.1/include
win32:INCLUDEPATH += C:/Qwt-5.2.1/include
FORMS += ui/
UI_HEADERS_DIR = inc_ui
OBJECTS_DIR = obj
MOC_DIR = moc
#mac:LIBS += /usr/local/qwt-6.1.0/lib -framework qwt
#mac:LIBS += -l /usr/local/qwt-6.1.0/lib/qwt.framework
mac:LIBS += -F /usr/local/qwt-6.1.0/lib -framework qwt
linux-g++:LIBS += /usr/local/qwt-5.2.1/lib/libqwt.so
win32:LIBS += C:/Qwt-5.2.1/lib/qwt5.dll
Any help is appreciated,
Thanks.

I've the following error during Qt compiling phase :

but I' dont fix it, any suggestion?
The platform is yocto form imx8.
Any suggestion? Thanks in advance

when i try to create file .ts with lupdate , the files are generated correctly , but the file .ts not cointeins the qstr strings that are into qml files. ( the file qml are into app.pro ), instead the string that i want to translate into .cpp files are all recognized correctly and put into .ts file.(these are into internal.pro) Where is the problem??
It seems that you are including your .qml files in .qrc resources but not in the project SOURCES itself. lupdate will not pick/parse your .qrc files to list .qml files.
So, you will have to add your .qml files to SOURCES either one-by-one or per directory.
lupdate_only{
SOURCES+=example.qml
SOURCES+=app/FancyControls/*.qml
}
This will duplicate your QML file entries in Qt Creator project pane tree which is not very desirable. So, you can comment out those lines in your .pro file and uncomment it before any lupdate. It's also mandatory to fence those imports in lupdate_only{} conditional statement. Make sure that there is no space between lupdate_only and the curly bracket. Actually, your C/C++ compiler would not expect a qml file to be compiled.
I made a muparser.pri which had the following content,
macx|win32|equals(build_muparser, "true")|!packagesExist(muparser){
message("Using bundled muparser")
MUPARSER_DIR = src/rel/muparser
DEPENDPATH += $$MUPARSER_DIR/include \
$$MUPARSER_DIR/src
INCLUDEPATH += $$MUPARSER_DIR/include
GEN_LIB_DIR = ../../generated/lib
LIBS += -L$$GEN_LIB_DIR -lmuparser
PRE_TARGETDEPS += $$GEN_LIB_DIR/libmuparser.a
}else{
message("Using external muparser")
CONFIG += link_pkgconfig
PKGCONFIG += muparser
}
I, then, added a
include(./muparser.pri)
in my application's make file.
This gave me an error
":-1: error: No rule to make target '../../generated/lib/libmuparser.a', needed by 'debug/Akaar1.exe'. Stop."
What did I do wrong? How else am I supposed to include this library in my project?
In your .pro file you can do:
LIBS += -L*path to the library* -l*library name: foo for libfoo.a*
Is there a way to use the HockeySDK within a Qt application? I made a basic test trying to import your framework into my project adding these lines to my profile:
# test.pro
LIBS += -F/Applications/HockeyApp.app/Contents/Frameworks -framework HockeySDK
OBJECTIVE_SOURCES += hockey.m
With the following code:
// hockey.m
#include <HockeySDK/HockeySDK.h>
void hockey() {
[[BITHockeyManager sharedHockeyManager] configureWithIdentifier:#"APP_IDENTIFIER"];
// Do some additional configuration if needed here
[[BITHockeyManager sharedHockeyManager] startManager];
}
But I have the following error:
error: 'HockeySDK/HockeySDK.h' file not found
Any help?
I fixed my problem using the following pro file:
# test.pro
QMAKE_CXXFLAGS += -F/path/to/the/folder/containing/frameworks
QMAKE_OBJECTIVE_CFLAGS += -F/path/to/the/folder/containing/frameworks
LIBS += -F/path/to/the/folder/containing/frameworks
LIBS += -framework HockeySDK
LIBS += -framework Foundation
OBJECTIVE_SOURCES += hockey.m
I tried to control my camera using OpenCV functions. The building progress is fine, however, when I tried to run my program it crashes and Qt only gives the information about the exit code -1073741515. I tried to comment all of the code using OpenCV function and the program seems to be OK. Are the libraries I included the wrong ones?
opencv.pro

Since MainWindow.cpp is long, I will just paste the constructor here and add the rest of them if needed.
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
cam = NULL;
frame = NULL;
timer = new QTimer;
imag = new QImage();
connect(timer,SIGNAL(timeout()),this,SLOT(readFrame()));
connect(ui->open,SIGNAL(clicked()),this,SLOT(openCamara()));
connect(ui->pic,SIGNAL(clicked()),this,SLOT(takingPictures()));
connect(ui->closeCam,SIGNAL(clicked()),this,SLOT(closeCamara()));
}
Finally GET IT WORK! When I try to run the app from Windows Explorer, it complains about lack of libstdc++-6.dll. Although there exist on under C:\QtSDK\mingw\bin, its version is incorrect for OpenCV 2.3 (or any other reason?) and will cause an error. I got one from here and the program runs correctly.
