LNK1117 Syntac Error in Option "". in QTCreator

mrjj

Hi
This project ?
https://github.com/PacktPublishing/Mastering-Qt-5/tree/master/Chapter_07

sandro4912

yes that one but i used the latest version opencv-4.1.0-vc14_vc15.

Since it only came with x64lib i builded the x86 lib myself with cmake but it looks like it wont link and give the error when i try to build the filter plugin designer

@sandro4912
Hi
Why not try small project linking to that OpenCV DLL to see if its the reason?
You seem to do it right and used the same compiler for app/plugin and openCV so
the usual suspects seem ruled out.

sandro4912

i linked opencv in a minimal project and also run it with Qt_5_12_2_MSVC2017_32bit in debug it run with no problems.

i used this test

#include "MainWindow.h"
#include "ui_MainWindow.h"

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    // read an image
    cv::Mat image = cv::imread("E://1.jpg", 1);
    // create image window named "My Image"
    cv::namedWindow("My Image");
    // show the image on window
    cv::imshow("My Image", image);
}

MainWindow::~MainWindow()
{
    delete ui;
}

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = untitled
TEMPLATE = app

CONFIG += c++11

INCLUDEPATH += E:\Cpp_Projekte\_library\OpenCV\opencv\build\include
LIBS += -LE:/Cpp_Projekte/_library/OpenCV/opencv/build/x86/vc15/lib \ -lopencv_world410

SOURCES += \
        main.cpp \
        MainWindow.cpp

HEADERS += \
        MainWindow.h

FORMS += \
        MainWindow.ui

However when it try to run it in release it get this error:

23:49:17: Running steps for project untitled...

The error i get is (Sorry for the german i think the message comes from my os):

:-1: error: LNK1181: Eingabedatei "\.obj" kann nicht geöffnet werden.

(It says Input file .\obj cannot be opened)

I have the feeling we shoukd solve this issue and solve with it the other one....

mrjj

Hi
Im pretty sure its somehow related.
the line
LIBS += -LE:/Cpp_Projekte/_library/OpenCV/opencv/build/x86/vc15/lib \ -lopencv_world410
i wonder if the \ is out of place when in one line ?

sandro4912

that solved the issue now i can run the simple example in debug and release.

However the real application still throws the strange error:

i changed the pro file to:

INCLUDEPATH += $$(OPENCV_HOME)/../../include
LIBS += -L$$(OPENCV_HOME)/lib -lopencv_world410

however i also tryed out to add the absolute path like in the simple example but no changes

mrjj

Hi
just for test.
Could you please use the exact same way as in mini sample?

INCLUDEPATH += E:\Cpp_Projekte_library\OpenCV\opencv\build\include
LIBS += -LE:/Cpp_Projekte/_library/OpenCV/opencv/build/x86/vc15/lib -lopencv_world410

just to rule out it has anything to do with $$(OPENCV_HOME)

sandro4912

i tred that but still get the same error

aha_1980

@sandro4912 Please make sure there are no outdated Makefiles in your source or build folder.

Then I'd close Creator, delete the build folder and the .pro.user and then open the project again to start from a clean state.

Regards

mrjj

@sandro4912 said in LNK1117 Syntac Error in Option "". in QTCreator:

fatal error LNK1117

Seems to be slightly known

Do you use Creator or the visual STudio Editor ?

sandro4912

I use the Creator.

I made the project new from scratch. Now it compiles and seems to create the plugin.dll

I assume it was maybe really some old files in the build folder.

However now i have annother problem. It looks like the form editor does not want to load the plug in correctly.

Any ideas what could cause this?

mrjj

Hi
Well make sure the plugin can find the openVC dlls.
Also that is in release mode,
and check you about Creator dialog
that compiler and Qt version used matches.

sandro4912

The output of the dll creation looks like this:

Im using Qt Creator Based on Qt 5.12.2 (MSVC 2017, 32 bit)
I compiled the opencv binaries with Visual Studio 2017 x86
I used the Kit Desktop_Qt_5_12_2_MSVC2017_32bit-Release

It should be compiled in release mode right?

From my understanding this shouldn't be a mismatch.

mrjj

@sandro4912
yes seems to be exactly the same. Qt / compiler wise.
Well, then it must be something with openCV dlls it cant find.
try to place the needed dlls next to the plugin.

sandro4912

what do you mean with putting them next to the plugin?

At the moment i get them from this folder:

Also i compiled opencv the static lib and not the dll could that be an issue?

mrjj

@sandro4912
Hi
well ifs its static it is part of the plugin so
it cant be that.

I assume openCV is happy to be static. ?

sandro4912

Yes i assume so. After all i used these libs in the short test application to test if opencv works. There everything seemed to work.

I used cmake to setup the opencv for compilation. is there maybe something set which doesn't go well with qt plugin?
