QtCreator 4.1.0 Qt 5.7.0 Windows 10 MinGW problem

[SGaist]

You should check content the of LIBS at the end of the .pro file to see if it contains anything suspicious.

[ad5xj]

Both libraries are generic libs from the authors of QWT and FFTW3. No customization. No references to anything like the C:\utils reference seen in the linker output.

[hskoglund]

Hi, perhaps you've previously built some Qt stuff, say a database plugin? I seem to remember that path C:\Utils is typically used in Jenkins environment setups.

[ad5xj]

Not the case here.

I have even tried to comment out the LIBS statements and the error still occurs.

[ad5xj]

Really???

None of you Qt Gurus have any idea why the compile and build toolchain injects this extraneous, un-configured stuff?

[VRonin]

Ok, lets go step by step: first we need to understand if the problem is in the pro file or in the build

could you try comment out this whole part:

unix:!mac {
FFTW3_INCL_PATH = /usr/include
FFTW3_LIB_PATH  = /usr/lib/i386-linux-gnu
SYSTEM_DEP_PATH = /usr/lib/i386-linux-gnu
QWT_INCL_PATH   = /home/ken/Projects/C++/qwt-6.1.3/src
QWT_LIB_PATH    = /home/ken/Projects/C++/qwt/lib
}

win32: {
FFTW3_INCL_PATH = "C:/FFTW3/"
FFTW3_LIB_PATH  = "C:/FFTW3/"
QWT_INCL_PATH   = "C:/QWT/qwt-6.1.3/src"
QWT_LIB_PATH    = "C:/QWT/qwt-6.1.3/lib"
SYSTEM_DEP_PATH = "C:/Qt/5.7/mingw53_32/bin/"
}

and everything that refers to them and then add them to the PATH environmental variable? Just call

set PATH=C:\FFTW3;C:\QWT\qwt-6.1.3\src;C:\QWT\qwt-6.1.3\lib;C:\QWT\qwt-6.1.3\lib;%PATH%

before you call qmake

[kshegunov]

Clean any cmake files, make sure you regenerate the makefile by running qmake ... and for the love of god enable the warnings and full output! You should fix up your configuration. On one hand you're building an application:

TEMPLATE = app

but then you require configuration for dlls?

CONFIG  += dll

Just use the minimum default set of CONFIG values and don't add things that aren't documented, or values whose usage you don't know.
For example:

QT += core gui widgets multimedia network
CONFIG += c++11
CONFIG -= app_bundle  # OS X only anyway

[ad5xj]

Well after considerable digging around I did find a reference to c:\utils in mingw53_32/mkspecs/qmodule.pri

I have not been able to re-compile yet but this surely does not belong here.

[ad5xj]

OK, just re-compiled and nothing has changed.

To your question about the CONFIG += dll it is latent from several attempts to get external libraries like FFTW3 and QWT to link their .dll files properly. That has been resolved and the .pro has been corrected. I also have tried to include only:

QT += widgets multimedia network
CONFIG += qt c++11 thread

makes no difference whatsoever.

[kshegunov]

Attach the full qmake and mingw32-make output, please.

[ad5xj]

Very well. Here is the qmake output:

11:57:24: Running steps for project ardoptnc...
11:57:24: Starting: "C:\Qt\5.7\mingw53_32\bin\qmake.exe" C:\Projects\C++\ardoptnc\ardoptnc.pro -spec win32-g++ "CONFIG+=debug"

And here is the compile/link output:

This application will compile and run on Linux Mint 18 Qt 5.7 32-bit compiled from source.

as mentioned above remove entirely

win32 {
CONFIG += windows dll
}
unix:!mac {
CONFIG += x11
}

also you never set the LIBS variable

LIBS += -L$${QWT_LIB_PATH} -L$${QWT_LIB_PATH} -lfftw3-3 -lqwt

also in the output, any idea where that <<<<< not required or requested <<<<< comes from?

[ad5xj]

While you may be correct about removing the CONFIG lines, It makes no difference in the current problem.

The LIBS line you mention was removed from the .pro in an effort to find the problem posted. It too make no difference in finding the problem.

[ad5xj]

I forgot to mention that I inserted the <<< lines to indicate the errant part of the output.

You should remove it nonetheless.

If you remove the LIBS line there is no sane way you'd be getting the same error. There's something very fishy here.

Could you also attach the generated Makefile.Debug? I don't see anything obviously wrong from the build log. Additionally, please check, if you have any files like .qmake.conf in your project directory?

This is strange!
How do you recompile the project? Are you sure you are re-running qmake? Qt Creator is very bad at detecting changes in the .pro file so if you just click on "Build" it won't "process" your pro file from scratch but use a cached version of it (I'm oversimplifying but it's not the point here)

also notice that the .dll part should not be included in the LIBS line.Your original post showed it.

[ad5xj]

I shall post the Makefile.Debug for you.

I seems strange because it is out of the ordinary. I posted here because I have done all the normal troubleshooting. I cleaned the project. Removed the Makefile. removed the compile generated folders (.obj, .moc, .ui, etc) and started over.

I have run the compile with and without the .dll. With and without the user LIBS line. It makes no difference.

As mentioned before this is a running project on Linux Mint 18. This is a problem unique to Microsoft Windows 10 Qt 5.7.0 32-bit MinGW. All the suggestions so far would affect the RUNNING application - NOT the problem posted. While I appreciate the suggestions, I would like to stay on topic.

BTW I have done a text search in the Makefiles for any reference to c:\utils and there is none. The only support or configure file I have found that does is the one mentioned before in the Qt install folder under mkspecs files. It is not something I can change with the QtCreator options.

I am still trying to figure out how to attach a file in this forum since the new format. I don't see it. Maybe someone can help there.

Use an external site and just post the link here. We don't have file/image uploads in the forum.

Or to your mint development setup being too lenient or both.

Nope, all the suggestions so far were definitely referring to the BUILD error you're getting.

While I appreciate the suggestions, I would like to stay on topic.

No one has strayed so far.

Well I have some progress albeit minor overall. I am able to compile all but the linker is not seeing the references to the .dll in the application. I will note that both QWT and FFTW3 folders are in the project path.

Here is the current .pro:

I get this error when linking (abbr for clarity):

The lines referred to are just library calls to FFTW. The fftw3.h is specified in the includes. The LIBS does have the correct path and it is in the project path - yet the undefined referreces. Something is not right at all.

[kshegunov]

@ad5xj
Your linkage is incorrect, thus the fftw isn't linked, thus you get the errors.

LIBS += -L$${FFTW3_LIB_PATH}/libfftw3-3.dll
LIBS += -L$${FFTW3_LIB_PATH}/libfftw3l-3.dll
LIBS += -L$${FFTW3_LIB_PATH}/libfftw3f-3.dll

should be:

LIBS += -L$${FFTW3_LIB_PATH} -lfftw3-3 -lfftw3l-3 -lfftw3f-3

And you should have the appropriate .lib (or .a if you're using mingw) files in $${FFTW3_LIB_PATH}.
