View source for Building QScintilla framework on macOS

By default, dynamic libraries files(.dylib) are generated after building the QScintilla project. For Qt libraries are built in form of frameworks by default, we will creating QScintilla framework here.

Modify Qt4Qt5/qscintilla.pro

Change the line:

CONFIG += qt warn_off release thread exceptions

to:

CONFIG += qt warn_off release thread exceptions lib_bundle


==Build and install==

/usr/local/Qt/4.8.7/bin/qmake # Qt is located in /usr/local/Qt/4.8.7

make

make install

cp -f -R /path/to/src/Qt4Qt5/Qsci /usr/local/Qt/4.8.7/include/

==Build example-Qt4Qt5==

Because we have built qscintilla2.framework, not qscintilla2.dylib，it is required to change applicatioin.pro：

CONFIG      += release qscintilla2

macx {

    QMAKE_POST_LINK = install_name_tool -change libqscintilla2.12.dylib $$[QT_INSTALL_LIBS]/libqscintilla2.12.dylib $(TARGET)

}

HEADERS      = mainwindow.h

SOURCES      = main.cpp mainwindow.cpp

RESOURCES    = application.qrc


to:

CONFIG      += release

macx {

	LIBS += -framework qscintilla2

}

HEADERS      = mainwindow.h

SOURCES      = main.cpp mainwindow.cpp

RESOURCES    = application.qrc


then, we compile：

/usr/local/Qt/4.8.7/bin/qmake

make


Run the program：

open application.app

We encounter error：

LSOpenURLsWithRole() failed with error -10810 for the file /Users/frankshong/Studio/Qt/3rd_party/QScintilla/QScintillaQt4/example-Qt4Qt5/application.app.

By default, OS X searches framework in /Library/Frameworks, but qscintilla2.framework is located in Qt directory. So we must specify the path.


Change library path with nstall_name_tool

install_name_tool -change qscintilla2.framework/Versions/12/qscintilla2 /usr/local/Qt/4.8.7/lib/qscintilla2.framework/Versions/12/qscintilla2 
application.app/Contents/MacOS/application

	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 283.0.0)


All right. Now we run：

open application.app

To deploy the program, run：

macdeployqt application.app
