There are many usefull Qt plugins, such as qwt, qextserialport, qxt and others. With a new major version of Qt, or a new version of a compiler I have to recompile the plugins to make sure everything is working well together. However many plugins are not compilable from comandline such that the resulting files can easily be deployed. Also they should be compilable with mingw and msvc.
Here I show the necessary modifications to enable compilation of everything necessary in a naming scheme for windows.
wwWidgets
The current release has a wwwidgets.pro file error that needs to be fixed otherwise compilation fails:
-unix:TARGET = $$join(TARGET,,,d) +win32:TARGET = $$join(TARGET,,,d) |
apart from that it contains the necessary steps to build debug and release and name them different
CONFIG += debug_and_release CONFIG += build_all |
Unfortunately the examples can only be compiled after system wide installation of the library. This can be fixed by adding a file common.pro with the content
INCLUDEPATH += ../../../../../include/qt/wwwidgets \ CONFIG += release CONFIG -= debug LIBS += -lwwwidgets4 -L../../widgets/release |
Please note that here all header files were manually moved to .../include/qt/wwwidgets
This common.pri is then called in every pro file of the examples, here widgetgallery.pro
FORMS += gallery.ui TEMPLATE = app CONFIG += wwwidgets SOURCES += main.cpp include(../common.pri) |
qwtPlot3D
This library has many problems. Its qmake files are only designed for msvc and the code does not compile. Additionally it can not be used to build debug and release builds.
qwtplot3d.pro
-CONFIG += qt warn_on opengl thread zlib debug +CONFIG += qt warn_on opengl thread zlib +CONFIG += debug_and_release +CONFIG += build_all -win32:TEMPLATE = vclib +win32:TEMPLATE = lib +CONFIG(debug, debug|release) { + win32:TARGET = $$join(TARGET,,,d) +} |
examples/common.pro
-CONFIG += qt warn_on thread debug +CONFIG += qt warn_on thread release +CONFIG -= debug win32{ - LIBS += ../../lib/qwtplot3d.lib + LIBS += -lqwtplot3d -L../../lib - TEMPLATE = vcapp + TEMPLATE = app |
src/qwt3d_function.cpp
+#include <stdio.h> |
Qwt
Here only the following needs to be enabled inqwtconfig.pri
CONFIG += debug_and_release CONFIG += build_all |
With Qt 4.6.x is does not compile. To fix this the following needs to be changed in qwt_valuelist.h. See this for discussion of the problem.
-#if defined(QWT_TEMPLATEDLL) -#if QT_VERSION < 0x040300 +#if defined(QWT_TEMPLATEDLL) && QT_VERSION < 0x040600 +#if QT_VERSION == 0x040600 |
QextSerialPort
Usual changes for the pro files, here qextserialport.pro. The examples project however has no chance to compile without the changes. Remove:
CONFIG -= debug_and_release #CONFIG += debug CONFIG += release |
and replace by
CONFIG += debug_and_release CONFIG += build_all |
also adding at the end
CONFIG(debug, debug|release) {
win32:TARGET = $$join(TARGET,,,d)
} |
The examples file QESPTA.pro is missing correct config and library path specification
+CONFIG += release +CONFIG -= debug -LIBS += -lqextserialport +LIBS += -lqextserialport -L../../ |
examples/qespta/MessageWindow.h
+#include <stdio.h> |
QCodeEdit
Removed the following line fromqcodeedit.pro, because it is never used anyway
CONFIG += debug |
lib.pro
-DESTDIR = .. -CONFIG += debug +win32{ + CONFIG += debug_and_release + CONFIG += build_all + debug:DESTDIR = ../deploy/lib/debug + release:DESTDIR = ../deploy/lib/release +} else { + DESTDIR = .. +} |
this required similar changes in further files, example.pro
-CONFIG += debug console +CONFIG += release +CONFIG -= debug -LIBS += -L.. -lqcodeedit +win32{ + debug:LIBS += -L../deploy/lib/debug -lqcodeedit + release:LIBS += -L../deploy/lib/release -lqcodeedit +} else { + LIBS += -L.. -lqcodeedit +} |
and equivalent in designer-plugin.pro
Qxt
required no changes at all.
