notepadqq compilation error: "Could not find feature thread"

[GNUser]

Hello, friends. Please, I'm trying to compile latest git version of notepadqq on my Pure64 11.0 laptop. The source code is available here:
https://github.com/notepadqq/notepadqq

I can get this far:

Code: [Select]

$ tce-load -wi compiletc qt-5.x-dev uchardet-dev
$ export QTMAKESPEC=/usr/local/lib/qt5/mkspecs/linux-g++
$ configure --prefix=/usr/local
$ make
...

Project ERROR: Could not find feature thread.
make: *** [Makefile:48: sub-src-ui-make_first] Error 3
How do I solve "Project ERROR: Could not find feature thread."?

Internet searches have not turned up anything helpful.

Are qt-5.x-all and intltool loaded?

[GNUser]

Yes, both are loaded.
Also, in the steps I listed it should be export QMAKESPEC (no "T" in it). Sorry for the typo.

I'm totally stuck.

[Juanito]

Does “make V=1” throw up any more errors?

[GNUser]

No. Same as before:

Code: [Select]

bruno@box:~/Downloads/notepadqq-master$ make V=1
cd src/ui/ && ( test -e Makefile || /usr/local/bin/qmake -o Makefile /home/bruno/Downloads/notepadqq-master/src/ui/ui.pro PREFIX=/usr/local QMAKE_CXX=c++ 'QMAKE_CXXFLAGS=-mtune=generic -Os -pipe ' QMAKE_LFLAGS=-Wl,-O1 LRELEASE=/usr/local/bin/lrelease CONFIG+= ) && make -f Makefile

Hi GNUser
What if you do this:

Code: [Select]

configure --prefix=/usr/local -no-feature-thread

[GNUser]

Darn, no. Same result.

[Rich]

Hi GNUser
How about this:

Code: [Select]

configure --prefix=/usr/local -no-warnings-are-errors -no-feature-thread

[GNUser]

Thank you, Rich. You had my hopes up with that one
Alas, same result.

[GNUser]

I found that these files in the  qt-5.x-dev  extension have "thread" in their name:

Code: [Select]

./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/QThread
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/QThreadPool
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/QThreadStorage
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/QThreadStorageData
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/qthread.h
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/qthreadpool.h
./tmp/tcloop/qt-5.x-dev/usr/local/include/qt5/QtCore/qthreadstorage.h
Maybe one of the steps in the build process does not know where to find these files on a TCL system?

[Rich]

Hi GNUser
You missed one:

Code: [Select]

/usr/local/lib/qt5/mkspecs/features/unix/thread.prf

[GNUser]

Thank you, Rich. I think I see what the problem is. At first I was getting an error related to linux-g++. I got around that error with this:

Code: [Select]

export QMAKESPEC=/usr/local/lib/qt5/mkspecs/linux-g++
Now the errors are related to thread. So it seems both errors may be related to mkspecs

Maybe I should be setting QMAKESPEC to something else?

[Rich]

Hi GNUser
Maybe you need to shorten it to:

Code: [Select]

export QMAKESPEC=/usr/local/lib/qt5/mkspecs

[GNUser]

Thanks, Rich. That helps somewhat. Now the error is different:

Code: [Select]

error!

I'm puzzled why  qmake  can't find things on its own.
Is it a problem with how  qmake  was packaged, or is it a problem with  notepadqq's  source code (making assumptions that are true for some distros but not true for TCL)?

[Rich]

Hi GNUser

... I'm puzzled why  qmake  can't find things on its own. ...

I found this:

Code: [Select]

./configure --prefix /usr --qmake /usr/lib/x86_64-linux-gnu/qt5/bin/qmakeover here:
https://www.linuxbabe.com/desktop-linux/compile-notepadqq-debian-ubuntu-raspbian
That site also list some packages I don't see in the repo (qt5-qmake, qttools5-dev-tools, etc) though it's possible they are included
in some other packages.
