Hi Peter

here using pthread

code & compiler warning

PRAGMA INCLUDE <pthread.h>

threaded.bac:18:27: warning: passing argument 3 of
'pthread_create' from incompatible pointer type [-Wincompatible-pointer-types]

it does compile and execs so puzzled by the warning

Hi Alex,

It is a bit out of scope for BaCon, but the function 'pthread_create' expects a function pointer as 3rd argument.

Please note BaCon is not designed to work with multi threading. Some programs may work, and some not - your mileage may vary

Instead, you can use the FORK function.

Hi Peter

Thanks for the reply

Looks like plan C

SYSTEM(./foo &)

to All the why

in the nav app I wish to convert openstreetmaps aka osm to openseamaps

if this be done internal to the app then the ui freezes until the updates are done that was
plan A:
this post plan B
Fork acts like Plan A
plan B: = no go after taking on-board what Peter says

Thanks again Peter

MM ! AGH.

Then started thinking HUG ? SYNC() GTK

Solution for this instance

stop the ui freezing while update : SYNC()

SUB SYNC()
WHILE gtk_events_pending() DO
gtk_main_iteration_do(FALSE)
WEND
END SUB

Hi Alex,

If you want to use async updates of a GUI which is defined in HUG, you can do this with TIMEOUT.

There is an example in this documentation which should help you on your way.

Thanks Peter

Sure it will .

this is the ui to date 'see screenshot at whitby :: osm maps + seamap open seamap(web) with gps coords & ais + tides
hence a lot going on

the web interface works with gtk web kit
and string is formed to , self explained

Hi All

Testing pi4 ubuntu desktop 64bit

what a pain

anyway partial update re bacon side

xterm install xterm and the neccessary fonts
sudo apt install xfonts-cyrillic
according to gtk3 + gtk2 + devs show installed this was not easy, but gtk4 updates held back and possible other bits of gtk3 and gtk2

the gui shows ?

launch from the term shows

GtkSourceView library for 'gtk2' not found! Trying GTK3...
Webkit library for 'gtk3' not found! Trying 'webkit2gtk'...

osm lib is also installed ,

Will be doing an update as regards this on another Thread

test code a message from a pi user
PRINT "Ubuntu DeskTop Sucks"
+ youtube playback is CRAP even with Chromium

Picky & summary

GTK-Webkit3 is a Washout

Hello Alex

we have equal opposite problems

you want to use gtk on the raspberry with webkit
and it is not working for you


I want to use Manjaro and it stopped working for the RPI3
it used to work and work well

I like Manjaro for many reasons
1.) it is a rolling release we always can try
the latest versions to keep one step ahead of the development cycle
2.) it is multi arch with an excellent package manager and excellent documentation
allows you to fine tune anything and build packages for starters
I feel very comfortable using Manjaro but less people use it on the RPI overall
3. Qt6 is the default but you can install Qt5 also


in time Manjaro will work again and I will install it
as my testing dev box



now for gtk and webkit I am on a clean install RPI3
and all is fine there I need webkit for a browser that have been working on
and am curious if the C code gps part will work on a static server using node
(since the static server is already working with the browser)


here is a pic of the static server working with Monaco
a browser based editor used by visual studio code
running inside the browser on http://localhost:8888

the same could be done in with the c code gps but
I havent tried to do that yet




here are the results on the rpi3


and the full report

sudo apt-get install libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev


*I think it is good you are using Manjaro and when I get another
chance to install it I will

Manjaro boots now!

After countless
Atempts to boot
It just flashed for a second then the led light stayed red
And nothing

I thought take a long shot and remove the hdmi cable and wait a minute to see if
the cpu was detecting still and the green light started to flash
and then I plugged in the hdmi cable and it worked!

Sounds like a miracle
Or something
had to eventually modify the /boot/config.txt
sourceforge.net/p/bacon-qt5/wiki/config.txt/
to get it stable

Joe

Hey Alex if you need any code to test I am on board with Manjaro
this is all bacon related installing bacon on archlinux

Xfce Manjaro again
[joe@joe-pc ~]$ uname -a
Linux joe-pc 5.15.56-1-MANJARO-ARM-RPI #1 SMP PREEMPT Fri Jul 22 13:22:49 UTC 2022 aarch64 GNU/Linux


basic setup a simple smart package manager ! (dependencies for a bacon build plus a few extra things for comfort)

sudo pacman -Syu clang curl enscript xterm indent flex geany gtksourceview3 fltk ksh make pkg-config



install bacon from fossil (for Manjaro Archlinux)
