Build static linked app with Qt5 on Windows

Redleouf · wrote on 4 Aug 2016, 05:01

I am new to developing on Windows and Qt and I am trying to build my app with static linking to avoid errors such as "missing msvcp140.dll" on systems who lack Visual C++ Redistibutable. I know there is other solutions for that problem but I still want to build my app with static linking to only have one executable people can launch.

I am on Windows 7 x64 and use the latest Qt5 version I built from source with static linking using thoses commands : perl init-repository && configure -developer-build -opensource -confirm-license -nomake examples -nomake tests -static && SET CL=/MP && configure -developer-build -opensource -confirm-license -nomake examples -nomake tests -static -opengl desktop && nmake

I then use nmake from Visual Studio 2015 to compile.

Here is my .pro file from my project :

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = LauncherCPC
TEMPLATE = app


SOURCES += main.cpp\
        mainwindow.cpp

HEADERS  += mainwindow.h

FORMS    += mainwindow.ui

RESOURCES = resources.qrc

RC_FILE = LauncherCPC.rc

CONFIG += static
#CONFIG += staticlib
CONFIG += debug_and_release

DEFINES += QT_NODLL
DEFINES += QT_STATIC_BUILD

QMAKE_CFLAGS_RELEASE += /MT
QMAKE_CXXFLAGS_RELEASE += /MT
QMAKE_CFLAGS_RELEASE -= -MD
QMAKE_CXXFLAGS_RELEASE -= -MD

And here are the errors I get when launching nmake (I removed some of the errors in the log because it was all the same and too many of them) :

Why is this happening? How can I build my app with static linking properly? I tried with Visual Studio 2015 and the Qt5 Add-On but it does the same (I changed the compilation from MD to MT in the settings).

I have read a lot of questions and answers on internet about all of that, but none of the solutions seems to work. I feel like my Qt5 build is not so static, but it should be.

Note that I also have a file in my project folder that is not present in the .pro file : ui_mainwindow.h. It seemed to have been generated by Qt, I don't know if I should add it to my .pro file.

Hi and welcome to devnet,

The default Qt build even if static uses the dynamic runtime. You are trying to build your application against the static runtime so it won't work.

You also have to modify the mkspec to link to the static runtime before building Qt.

Important note: don't forget the licensing implication when doing a static build.

Also, drop the the -developer-build option since you're not hacking on Qt.

Thank you for your answer. So I need to rebuild my whole Qt with the -static-runtimeoption passed to configure for it to work right?

Is that what you mean by modify the mkspec?

SGaist · 8 Apr 2016, 15:54

No but it's even better. I've missed that new option of configure. Before it, you had to modify Qt's msvc-XXX mkspec to change the runtime option passed to the compiler/linker.

So yes, you have to rebuild Qt with it and it should be enough.

Indeed it did the work, it is working fine now, thank you :)
