Building on Windows

[Joep Admiraal]

I am trying to build the current version (checkout from original master) of QLC+ on Windows 7 32bit.
I installed these components:
- QT5.1.1-mingw
- mingw 4.8.1
- fftw3-3.3.3-1-mingw32-dev
- glib_2.24.0-2_win32
- pkg-config_0.26-1_win32

In powershell I go to c:\qlcplus and run qmake and mingw32-make.
I get the following result:

PS C:\qlcplus> mingw32-make.exe
cd hotplugmonitor\ && ( if not exist Makefile C:\Qt\Qt5.1.1\5.1.1\mingw48_32\bin\qmake.exe C:\qlcplus\hotplugmonitor\hot
plugmonitor.pro -o Makefile ) && C:/MinGW/bin/mingw32-make -f Makefile
mingw32-make[1]: Entering directory 'C:/qlcplus/hotplugmonitor'
test wordt niet herkend als een interne of externe opdracht, programma of batchbestand.
De syntaxis van de opdracht is onjuist.
Makefile:39: recipe for target 'sub-src-make_first' failed
mingw32-make[1]: *** [sub-src-make_first] Error 1
mingw32-make[1]: Leaving directory 'C:/qlcplus/hotplugmonitor'
Makefile:50: recipe for target 'sub-hotplugmonitor-make_first-ordered' failed
mingw32-make: *** [sub-hotplugmonitor-make_first-ordered] Error 2

It seems it is expecting a program or batch file called test and it does not exist.
Do you have any idea what the problem can be?

Thanks,
Joep

...like if I speak dutch...

Anyway, as stated in the QLC+ wiki: https://github.com/mcallegari/qlcplus/wiki
"Note: QLC+ hasn't been ported to Qt 5.x yet. So let's stick with Qt 4.8.5 for now !"

[Joep Admiraal]

Well, I noticed this commit:
da8ea7a845b4e8e6a0329f066b2bc733702e83db HUGE one - QLC+ ported to Qt5 !

So I thought lets give it a try.
I did this in a virtual machine so can easily switch back to my Qt4 machine for now.

[Massimo Callegari]

It's not official and it's not tested on Windows.
I just built it and launched it on Linux.

Have you ever compiled QLC+ on Windows ? (with Qt 4.8.x)
I assure you it's a pain in the ass

[Joep Admiraal]

Yeah I tried with 4.8 and ran into trouble before.
I will do a clean setup tonight (as described in the wiki).
I want to test my changes for the sysex messages on Windows

[Massimo Callegari]

I see. If you want I can help. I've got a working environment at home.
The only thing is that I don't know how to monitor sysex on Windows
I can try with this: http://www.midiox.com/

[Joep Admiraal]

Ok, I did another test on a new VM. I used a QLC+ revision from just before the Qt5 commit. I followed the instructions from the wiki.
I used the same software as stated in my first post except for Qt which is now 4.8.5.
One thing I noticed is that the Qt installation complains about W32API3.13 because MinGW has a newer version of this file.

Now when running qmake and make from powershell I get this error:
./debug\avolitesd4parser.o:avolitesd4parser.cpp:(.eh_frame$_ZN7QStringaSEPKc+0x13): undefined reference to `__gxx_person
ality_v0'

I attached a more complete error log.
Googling this error shows similar errors when gcc is used when g++ should have been used. I doubt that this is the case since the logs show g++ is used.

Any ideas?
Thanks

[Massimo Callegari]

Did you forget to install g++ when you installed MinGW ?
What does g++ -v say ?

EDIT: By the way, the changes to work on Qt5 are backward compatible. QLC+ still compiles on Qt 4.8.x

[Joep Admiraal]

g++ is installed with MinGW.
g++ -v output:

[Massimo Callegari]

Hmmm...GCC 4.8 might be problematic...although I had reports of users compiling with it on Linux.
I use Windows 7 64bit and mingw 32 bit on GCC 4.6.
I can try your same steps one of this nights but I'm not sure if I have enough time (also, spending time on Windows makes me nervous... )

[Massimo Callegari]

By the way, have you set the environment variables like PATH, QTDIR and so on?
I remember I got a hell of time on that

[Joep Admiraal]

Yes environment vars are in place.I noticed that the package gcc-v3-g++ was also installed. So I removed the normal g++ package and tried to compile with the v3 version. That did not work. Then I compiled with only the normal g++ package in place and that did work.It then complained about openssl but once that was installed make completed without errors.I will do some more tests and then update the wiki.

[Massimo Callegari]

Just a tiny note on openssl. I guess you found that issue building the webaccess module. It is not needed and yesterday I pushed a little fix on the mongoose flags.

Honestly I've never heard about v3 and non v3 g++ package. Before updating the wiki, please let me double check the procedure.

Thanks

[Joep Admiraal]

I did make install and renamed the .a files to .dll files.
Now when I try to strart qlcplus.exe I get an appcrash:

Cannot start the application (0xc0000005).

Signature:
P1: qlcplus.exe
P2: 0.0.0.0
P3: 52663c2b
P4: QtCored4.dll
P5: 4.8.5.0
P6: 51cc9cc0
P7: c0000005
P8: 001e1b7c
P9:
P10:

It generates a crashdump file, but before I start analysing that, do you have any idea what this could be?

[Massimo Callegari]

Windows is terrible when it comes to debug something. I see what you see: a crash somewhere into QtCore

Did you launch it from a terminal or double clicked from windows explorer ?
Have you copied the additional DLLs needed for audio and OSC ?
Obviously it all depends if you built them in or not

[Massimo Callegari]

A quick summary. I've spent 2 hours on Windows and I got...nowhere !
I saved my previous mingw installation and I tried to rebuild it from scratch with the new installer.
First, they changed it all. Now it's fully graphic. Might be better or not.
After downloading all the base system, I opened a powershell and the command "make" does absolutely nothing. (gcc and g++ work ok)

So I opened a MSYS shell and got a little bit further. Although I got stuck again, cause for some reason qlcconfig.h doesn't exist.
It is supposed to be created by qmake.

I can spend some more time, maybe tomorrow, but this is indeed a problem.

[Joep Admiraal]

I am able to compile QLC (without the plugins, except for midi).
If you have other (more important) things to work on, please do so.
For me this is not a high priority issue, and eventually I will find the cause of this problem. When I got it running I will update the wiki.

[Massimo Callegari]

I've been able to understand the issue of compiling with MSYS shell. It's more UNIX style.
After building the whole QLC+ I got your same result: error 0xc0000005.
Gonna investigate this later.

[Massimo Callegari]

I fear this is it: https://qt-project.org/forums/viewthread/21853/
Means latest MinGW is not binary compatible with Qt 4.8.5.

[Joep Admiraal]

Ah great you found the problem.
I tried MinGW 4.4 and it works.

Thanks for looking into this.
