RPI4 GTK

[alexfish]

Hi All

Raspberry OS
latest gtk updates prove to be a downer

have been testing other os's mainstream ubuntu

eventually install latest Ubuntu Desktop , something Jammy / jellyfish
managed to get gtk devs working
results of gtk webkit = disaster
in short I think that jellyfish = japanese man o war ::

So tried Manjaro , first choice KDE Plasma
and in the short got Bacon working + hug
the long of the short
pkg-configs did not work ?
'why does a series of question marks = smilies'
like
PRAGMA LDFLAGS `pkg-config gtk+-3.0 gobject-2.0 gthread-2.0 --libs`
What, yes
first time ever and did not know this, the solution
pamac install pkg-config
installing packages is a no-brainer apart from that bit
+ youtube speed = much same if not slightly than pi os

Do I like it , dev wise , need to test further, Desktop wise ,Wow

Hope to be back on track dev wise, soon + waiting and hoping Pi OS gets sorted

now this code works RE libosm
'Requires libosmgpsmap-1.0-dev libgtk-3-dev
PRAGMA LDFLAGS `pkg-config gtk+-3.0 osmgpsmap-1.0 gthread-2.0 --libs`
PRAGMA OPTIONS `pkg-config gtk+-3.0  osmgpsmap-1.0 --cflags`
PRAGMA INCLUDE <gtk-3.0/gtk/gtk.h>
PRAGMA INCLUDE <osmgpsmap-1.0/osm-gps-map.h>


OPTION PARSE FALSE

LOCAL window TYPE GtkWidget *
LOCAL map TYPE OsmGpsMap *
LOCAL source$ TYPE OsmGpsMapSource_t

'g_thread_init(NULL)
gtk_init (&argc, &argv)

source$  = OSM_GPS_MAP_SOURCE_OPENSTREETMAP

map = g_object_new (OSM_TYPE_GPS_MAP, "map-source", source$, "tile-cache", "/tmp/", NULL)


window = gtk_window_new (GTK_WINDOW_TOPLEVEL)
gtk_window_set_title (GTK_WINDOW (window), "BaCon Rules")
g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL)
gtk_container_add(GTK_CONTAINER(window), GTK_WIDGET(map))

gtk_widget_show (GTK_WIDGET(map))
gtk_widget_show (window)
gtk_main ()

Hi All

as regards Manjaro pi / gps , permissions : Navigation 2 thread

at present I am running this app as root..

looks like manjaro has a means of identifying the device , hence should be able to write the udev rules

the tool is in System info-center device

example

u-blox 7 - GPS/GNSS Receiver

Manufacturer: u-blox AG - www.u-blox.com

Class
2
(Communications)
Subclass
0

Protocol
0

USB Version
1.10

Vendor ID
0x1546
(U-Blox AG)
Product ID
0x01a7
([u-blox 7])

Speed
12 Mbit/s

Channels
0

Max. Packet Size
64

from here best possible howto to-date is HERE
if find others + updates will be posted on Navigation 2 thread

note: Plug your device in before booting up

Tested all the rules under the sun All fail,
Will update navigation 2 thread to use gpsd/gps lib , devs are installed at default at 'install gpsd , have tested and works without permissions
Hence ::serial interface will gone::

as a side note could not find a colour terminal suitable for sixel
however Kterm can display images with kitty and its kittens
kitty +kitten icat test.png
see screenshot

MM!


OS: Manjaro ARM Linux aarch64 kde plasma
found a x11 window render cairo problem:

My Own osm/openseamap app does not render the images: yet the cairo context / surface works
no error's show in the terminal ?
now looking further:: will test Vovchik's x11 thread and report back

for new readers this app does not use a toolkit : uses xlib + cairo

Picky of the app with no render but the input(entry works)
