Unknown module(s) in QT: websockets

Maurizio · October 2019

As I tried to compile Gideros, I got the subject error message:

qmake ui.pro
Project ERROR: Unknown module(s) in QT: websockets

I've downloaded just now Gideros sources and installed ex novo Qt, version

qt-opensource-linux-x64-5.13.1

Following the "how to build Gideros on Linux" guide,
I was able to compile FontCreature, TexturePacker and Qscintilla,

then starting qmake ui.pro I got the above error

Any suggestion ?
Best regards

Maurizio.

Maybe you didn't install Qt5 WebSocket extension along with QT itself ? There may be a checkbox to tick (or to not untick) during QT install

Maurizio · October 2019

I just reinstalled qt5 using the online installer, and with the options reported in the attached picture (there is no WebSocket checkbox in those), and I have the same problem ...

MoKaLux · October 2019

I don't know how to solve your problem. You may have seen those pages:
https://doc.qt.io/qt-5/qtwebsockets-index.html
https://archlinuxarm.org/packages/arm/qt5-websockets

Maybe you need to install it outside of QT installer?
also this link may help?

https://forum.qt.io/topic/46131/project-error-unknown-module-s-in-qt-websockets
Could that help ?

Maurizio · October 2019

Thanks, the command "sudo apt-get install libqt5websockets5-dev" solved THIS problem,
however now the make command returns the following error:

/usr/bin/ld: impossibile trovare -lqscintilla2_qt5
collect2: error: ld returned 1 exit status
Makefile:482: recipe for target 'GiderosStudio' failed

The translation is: Impossible to find -lqscintilla2_qt5

Please note that before compiling UI I managed to download, compile and install the package QScintilla-gpl-2.8.4

Any suggestion ?

Maurizio

hgy29 · October 2019

Yes, it may be because we use more recent versions of qscintilla nowadays, the most recent version is fine with gideros. They changed the name of the resulting lib recently, so gideros code actually expects a more recent version, and the online doc wasn’t updated accordingly. I’ll do it ASAP.

hgy29 · October 2019

Hey, I was about to update the doc to find out is was already updated: https://wiki.giderosmobile.com/index.php/Compiling_Gideros_Source#1.8_Install_QScintilla

Maurizio · October 2019

Well, I've downloaded, compiled and installed just now qscintilla_gpl-2.11.2, so I managed to compile gideros/UI and to start GiderosStudio.

Then I managed to compile the packages

libgvfs
libpystring

However these is not a package called liblua
so, what should I do ?

A simple 'make all' should compile evrything is environment is set up correctly, and 'make qtapp.install' should get you started if you just need QT tools (studio,player,etc).
Are you really following the compilation guide (https://wiki.giderosmobile.com/index.php/Compiling_Gideros_Source) ?

Maurizio · October 2019

Well, before this answer I tried to compile it following a text file called "how to build Gideros on Linux" (I don't remember where I found it).
Now, trying to follow the on line document, I'm stuck on point 1.12.2, where there are no directions
on how to install it under Linux.

E.g. what have I to specify at the voice QTBASEDIR ?
Perhaps ~/QT or ~/QT/5.10.1 ?

And what about the other voices ?
Best regards

Maurizio.

MoKaLux · October 2019

not on linux here.

It is hard to say without knowing where you installed your QT. The trouble with linux is that each distribution behaves differently, so difficult to give a guide that will work for everyone. I did it not long ago though, let me find my Makefile.def and post it here.

hgy29 · October 2019

Ok, so I had a look and you just need a few lines:

QTBASEDIR=~/QT
QT_ARCH=gcc_64
QT_TOOLSARCH=gcc_64
QTVER=5.10.1

The lines above are enough to build Gideros tools on Linux

hgy29 · October 2019

BTW I had another try at building it on Linux and found out that some things weren't compiling correctly due to recent changes. I pushed an update to git to fix these things, so you'll have to 'git pull' to get them.

Maurizio · October 2019

Well, now the compilation fails as follows:

hgy29 · October 2019

Maybe there is a libqt5opengl5-dev package for your Linux ?

hgy29 · October 2019

BTW if you succeed in building Gideros on Linux, I'd be glad if you could report here what should be changed in the doc

Maurizio · October 2019

Ok, I've installed the missing lib, now I have another problem:

however I've seen that the files are actually existing
e.g. libicudata.so (and libicudata.so.56) is a simbolic link to libicudata.so.56.1, and the same is to the other libs
so, what's happening ?

Really strange! I don't get why cp says the file doesn't exists since it obviously does!

hgy29 · October 2019

Ahh, wait, there is a '-P' option on the cp command line, I think that should be removed.
Can you remove them in scripts/GidQTLinux.mk and try again ? I am not sur why they were added, although I did it!

Maurizio · October 2019

The trouble is also due to the fact that I have installed Qt in a directory "Qt" and not "QT"

(look at the case)
Having renamed that in QT, now the copy get done, but the script halts in another place
(another -P option ?)
where is it ?

gcc -c -o emscripten/lzma/LzFind.co -D_7ZIP_ST emscripten/lzma/LzFind.c
gcc -c -o emscripten/lzma/LzmaEnc.co -D_7ZIP_ST emscripten/lzma/LzmaEnc.c

cp: impossibile eseguire stat di '/home/maurizio/QT/5.10.1/gcc_64/lib/libqscintilla2_qt5.so*': File o directory non esistente
/home/maurizio/gideros/scripts//

hgy29 · October 2019

Yes, possibily another -P option, but if renaming the folder did the trick it should work for other files too. Can you check that qscintilla lib is present and match the name ? Otherwise about QT dir case, it was enough to change it in Makefile.def to match your setup.

Maurizio · October 2019

In this case the file is missing. I compiled qscintilla using the following directions:

To build Gideros player you will need to install Qscintilla also:

http://sourceforge.net/projects/pyqt/files/QScintilla2/QScintilla-2.8.4/QScintilla-gpl-2.8.4.zip

unpack this then

cd /Qt4Qt5
qmake qscintilla.pro
make
make install

(Instead of the suggested package I have downloaded the last version, QScintilla_gpl-2.11.2)

So probably the package is not in the correct place.
What can I do ?
