If pyqt5 involves installing qt5, which is huge, using pip is going to use a lot of ram.

You'd probably be better off compiling qt5 and pyqt5 and making extensions out of them.

[ketank]

Thank you Juanito

compiling qt5 is something I was avoiding but seems no option ...

let me try and that post an update if I could do that

[ketank]

Hi

I am trying to compile qt5 following the instructions at - http://tinycorelinux.net/11.x/x86_64/tcz/src/qt-5.x/

The problem is step to where I have to extract the qt5 tar. It end with
tar: can't open 'qt-everywhere-src-5.14.0/qtwebengine/src/3rdparty/chromium/cc/raster/raster_buffer.h': No space left on device

I am using a 32 G card and 8 GB RAM.
I feel it is limited by the RAM...

PLEASE HELP!!!!

[Juanito]

You need to compile on permanent storage - I use an external usb hd, but you can also use a usb stick.

It is surprising you can't extract the qt5 tarball in 4gb ram (limited by 32-bit piCore) - what else do you have in ram?

[ketank]

I will try extracting to a USB drive.

Its a fresh installation and have just installed the requirements based on compile_qt-5.x. nothing else.

RMA is using 738 MB (see attached)

Hi Juanito

... It is surprising you can't extract the qt5 tarball in 4gb ram ...

Not really that surprising. If you look here:
http://tinycorelinux.net/11.x/x86_64/tcz/src/qt-5.x/
The listing shows the compressed tarball is over 500Mb in size:

Code: [Select]

qt-everywhere-src-5.14.0.tar.xz                    11-Dec-2019 12:00           547854788Since the contents are primarily text, I imagine it compresses very nicely. At 8 to 1 you are over 4Gb plus whatever
workspace is required to decompress plus the 700Mb shown being used in his screenshot.

The screenshot also shows 2Gb of swap. Is that on permanent storage or also in RAM?

Out of curiosity I placed a few source files into a directory and made a compressed tarball out of them:

Hi Rich,

It is a separate SWAP file.

[ketank]

Current status -
Could not build qt5 based on http://tinycorelinux.net/11.x/x86_64/tcz/src/qt-5.x/
If is failing to create the libraries.

Working to build the latest version 5.12 from source. Will update the progress.

Question - I have to build some other components for the same.
I am building the tcz packages say for cmake right now (the one available in the Pi Core release is older one).

Who and How should I send these packages so they can be used by others too?

[Rich]

Hi ketank
If you are considering submitting an extension, Instructions can be found here:
https://web.archive.org/web/20200208152109/http://wiki.tinycorelinux.net/wiki:creating_extensions#submitting

Use the  tcesubmit  email address, not the  picoresubmit  address.

[ketank]

Thank you Rich

[Juanito]

If is failing to create the libraries.

What error did you get?

[ketank]

It was an issue with old version of cmake.
built and installed cmake.

now the problem is with perl.
I have installed perl5.tcz but perl command not found. It is a requirement for qt5

I have no idea about perl so ... reading around...

any help will be appreciated.

[Juanito]

qt5 is probably looking for /usr/bin/perl - you can make a symlink to /usr/local/bin/perl

[ketank]

perl is not even available in /usr/local/bin/ also
