I want to run my app created with QtSDK
on a machine that does not have Qt
installed.
I tried to copy the DLL's
from the BIN
folder to the release of my project, but it did not work.
dll's
folder d:\Qt\Qt5.0.1\5.0.1\mingw47_32\bin
d:\projects\mybrowser\mybrowser-build-Desktop_Qt_5_0_1_MinGW_32bit-Release\release
without Qt
without Qt
, I installed vcredist_sp1_x86.exe
and tried to run my application browsertest.exe
microsoft visual c++ runtime library: this application has requested the runtime to terminate it in an unusual way
Q: What I really want to know:
How do I run an application built in Qt on other computers (Windows) without Qt installed?
Folders:
Qt/Mingw:
File .pro:
QT += webkitwidgets network core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = browsertest
TEMPLATE = app
RC_FILE = browser.rc
SOURCES += main.cpp\
mybrowser.cpp
HEADERS += mybrowser.h
FORMS += mybrowser.ui
If any information you missed, please let me know. grateful
To distribute your application you need to copy the DLLs (only the DLLs necessary).
Copy the DLLs necessary from
<DRIVE>:\Qt\Qt<Version_qt>\<Version_qt>\mingw<Version_mingw>\
or <DRIVE>:\Qt\Qt<Version_qt>\<Version_qt>\mingw<Version_mingw>\bin\
eg.: C:\Qt\Qt5.2.0\5.2.0\mingw48_32\
or C:\Qt\Qt5.2.0\5.2.0\mingw48_32\bin
Paste the folder of your application.
Then copy the folders inside of <DRIVE>:\Qt\Qt<Version_qt>\<Version_qt>\mingw<Version_mingw>\plugins
eg.: C:\Qt\Qt5.2.0\5.2.0\mingw48_32\plugins
Paste the folders of your application.
Note: In this example (below), it was necessary to copy DLLs from different places and remove the Debug DLLs (used only to compile in Debug).
Note that the
debug dlls
end with "d.dll", for example: Qt5Core.dll and Qt5Cored.dll or Qt5Concurrent.dll and Qt5Concurrentd.dll, the ending with "d.dll" should not be copied.
The structure should look something like this (example):
Only some DLLs the mingw will be needed, so I recommend using the Dependency Walker 2.2
The result should look like this (not all dlls are needed, this can vary by project type):
Thanks to:
+1 for @MartinBeckett, showed me the program to find the DLLs required.
+1 for @WouterHuysentruit, thanks to the application I indicated, I discovered that the contents of the mingw\plugins folder should go straight into the application folder.
@WouterHuysentruit I would consider your answer as correct, but you just said, so I put a simpler explanation. Thanks anyway.
