[SOLVED] Problem installing Qwt 6.1.2 in Qt 5.40

BDifferent

Hi all,
I am trying to install Qwt 6.1.2 in a fresh Qt 5.4 installation (MinGW) on Windows 7.
I have done that successfully on another machine (on which I had to work in Safe Mode while installing Qt to circumvent interference of Bitdefender which blocked qmake).

On the current PC Qt was installed without problems, however, Qwt stops at some point. See below for the output of mingw32-make:
...
compiling qwt_slider.cpp
compiling qwt_thermo.cpp
compiling qwt_wheel.cpp
moc qwt_dyngrid_layout.h
cygwin warning:
MS-DOS style path detected: /cygdrive/c/Qt/Qt5.4.0/5.4/mingw491_32/bin/C:\Qt\Q
t5.4.0\5.4\mingw491_32\bin\moc.exe
Preferred POSIX equivalent is: /cygdrive/c/Qt/Qt5.4.0/5.4/mingw491_32/bin/C:/Q
t/Qt5.4.0/5.4/mingw491_32/bin/moc.exe
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
C:\Qt\Qt5.4.0\5.4\mingw491_32\bin\moc.exe: not found
Makefile.Release:648: recipe for target 'moc/moc_qwt_dyngrid_layout.cpp' failed
mingw32-make[2]: *** [moc/moc_qwt_dyngrid_layout.cpp] Error 127
mingw32-make[2]: Leaving directory 'C:/qwt-6.1.2/src'
Makefile:38: recipe for target 'release-all' failed
mingw32-make[1]: *** [release-all] Error 2
mingw32-make[1]: Leaving directory 'C:/qwt-6.1.2/src'
makefile:41: recipe for target 'sub-src-make_first-ordered' failed
mingw32-make: *** [sub-src-make_first-ordered] Error 2

However, moc.exe is there. I also tried safe mode to eliminate the possibility that ESET Antivirus interferes. But it always stops at the point where moc.exe comes into play.

I could turn off the warning as described in the message, but the problem would still be there. I also tried to find the mentioned path in the makefiles to change it manually, but didn't find it. So I am a bit lost here.

Any ideas?

Hi BDifferent,

I found the same problem today.
I did not found the root cause of the problem but there is a workaround.
Replace all C:\Qt\Qt5.4.0\5.4\mingw491_32\bin\moc.exe entry in the Makefile and src/Makefile.Release (or debug if you try to build it with debug) with the correct cygwin style path: C:/Qt/Qt5.4.0/5.4/mingw491_32/bin/moc.exe

And do the same with the C:\Qt\Qt5.4.0\5.4\mingw491_32\bin\rcc.exe in Makefile because it will generate another error otherwise.

I hope this will solve your problem, too.

That is the part you have to solve. You will need qmake anyway. Have alook how to convince bitdefender that qmake is not a virus.

With qmake you are generating a makefile compatible with your OS.

That seems to be a misunderstanding; that part you quoted was a different PC on which installation of Qt was blocked by Bitdefender, while installation of Qwt was not a problem.

On the current machine, which is why I started this thread, installation of Qt was not a problem (ESET Antivirus running here), but Qwt installation failed.

I did that and it worked, thanks :-) I had looked for occurrences of moc.exe in the Qwt folder already before, however after running "qmake qwt.pro" but before "mingw32-make", which is why I found no occurrences at that point of time.

Will change the title to SOLVED, although the source of the problem is not clear, but my problem was solved.
