QtCreator 4.1.0 Qt 5.7.0 Windows 10 MinGW problem

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.

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.

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

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:

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.

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.

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}.

Do you only get errors for FFTW, or Qwt as well?

LIBS += -L$${FFTW3_LIB_PATH} -lfftw3-3.dll

That's supposed to be -lfftw3-3 (no ".dll")

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

FFTW3_LIB_PATH == "C:/FFTW3/", right? That means your lines expand to things like LIBS += -LC:/FFTW//libfftw3-3.dll (2 slashes).

Let's do a sanity check: Replace all the variables in your *.pro file with hard-coded paths, e.g. LIBS += -L"C:/FFTW3/" -lfftw3-3 -lfftw3l-3 -lfftw3f-3 and see what happens.

[EDIT: @kshegunov beat me to it!]

HEADERS += $${FFTW3_LIB_PATH}/fftw3.h

...

HEADERS += \
    $${QWT_INCL_PATH}/qwt.h \
    $${QWT_INCL_PATH}/qwt_plot_spectrogram.h \
    $${QWT_INCL_PATH}/qwt_scale_map.h

Do not add 3rd-party library headers to HEADER. Instead, add their folders to INCLUDEPATH.

By adding the files to HEADER, you are asking the toolchain to compile the headers into your binaries. This causes errors if the headers contain any definitions that have already been built into the 3rd party DLL. This also causes Qt's code generator (moc) to generate a new copy of the QObjects that are found in the headers, which breaks the signal-slot mechanism (among other things) for the library.

LIBS += -L$${QWT_LIB_PATH}/ -lqwt

This is not strictly necessary, but the cleanest way to use Qwt in your project is to write include(C:/QWT/Qwt-6.1.3/features/qwt.prf) in your *.pro file. You can then get rid of all the other Qwt-related lines.

ad5xj

Thanks for the QWT tip I will try that.

As to the fftw3 dlls ... I did have it the way you describe and the linker complains. With some experimentation, I did find the current syntax to work. It may not be as expected but it works. Go figure.

I have had little nor no problem with QWT. No error messages about the QWT .dlls at all.

SGaist

What exact error do you still have with Qwt ?

When you say "it works", do you mean everything builds and links correctly? Or that the linker doesn't complain about missing libraries? There's a difference.

A typo in -l gets reported directly by your toolchain. Example:

LIBS += -L"C:/FFTW3/" -lfftw4-4

...

ld.exe: cannot find -lfftw4-4

In contrast, a typo in -L does not get detected or reported directly. Instead, you just get the generic "undefined reference" errors.

Anyway, note also that:

-L is for specifying a folder that the linker should search
- -LC:/FFTW3/libfftw3-3.dll makes your toolchain look inside a folder called "C:/FFTW3/libfftw3-3.dll/"... which probably doesn't exist (but the toolchain doesn't tell you that)
-l is for specifying a filename root
- -lFoo makes your toolchain link against a file called libFoo.dll (inside the folders specified by -L)

As to the fftw3 dlls ... I did have it the way you describe and the linker complains.

Please try again, especially with hard-coded paths. Then, post your unmodified .pro file and error messages.

ad5xj

Sorry for being ambiguous. I mean to say the linker finds the libraries and tries to link. Whereas before it could not find the libraries -lfftw3-3.dll or -lfftw3.

I understand your explanation to be the expected. I am only reporting the actual results of repeated attempts with failure before hitting on what works even if it is not what "should" be correct.

BTW SGiast I do not now, nor ever have had a problem with QWT libraries during the compile and link process. Sorry if I was not clear before.

No worries. So, does that mean all problems are gone now?

ad5xj

Well I do not know how to answer you JKSH.

It seems the LIBS statement is not interpreting the path and .dll name correctly for FFTW3 dll's. As you pointed out earlier, if the correct syntax is used, the linker does not find the libraries. When specified as -L<path>/<libname.dll> the linker seems to find the libraries and tries to link with them. Not sure if that is a bug in the Windows 32 bit version of qmake or something else. It needs to work as advertised but doesn't.

I also notice that if a substitution like $$FFTW3_LIB_PATH is used but not defined, the qmake hangs indefinitely without giving a message. Something new I just discovered.

I will also say that in desperation, I have uninstalled Qt, cleaned the registry and file system, and reinstalled Qt with no change in the problem.

At this point I believe the LIBS problem is a bug and possibly the substitution problem as well.
