Ah -- that was the one!  I thought it was gdal for some reason...
flaky memory :)

We should really investigate why this caused a silent failure to show
the algorithms instead of an error...


Yes, an error message could be beneficial. I remember from previous 
installations that QGIS would complain on opening that psycopg (or other 
python modules) weren't installed.

Double check that you have the gdal python packages installed

Thanks for this,

from osgeo import gdal

just works, so I guess it is installed.

What is the value of
BINDINGS_GLOBAL_INSTALL
in your compile config?

The value is "YES"

Looks like something is not picked up with your install.

Agree

What if you run qgis 31.8 from the 'output/bin' dir in your build directory?

Behaves just the same

If all fails I would (I think) compile and set CMAKE_INSTALL_PREFIX in some 
local dir in your HOME

I did in ~/bin/qgis_/3.18/debug (for debug build):

And create a startup script like

export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
export PYTHONPATH=~/bin/qgis_/3.18/debug/share/qgis/python:$PYTHONPATH
export QGIS_DEBUG=0
# passing ALL parameters to qgis bin
# eg to be able to call a certain translation
# qgis --lang nl
~/bin/qgis_/3.18/debug/bin/qgis "$@"

Thanks, will think about this and try it.

Thank you again for your ansers. I see I have a sort of linking/library
problem. GRASS is installed and GRASS modules are compiled but then
these do not appear either in the menu.

YES! That was the problem!

Re: [QGIS-Developer] Building QGIS with Visual Studio 2019 CE and vcpkg

[Mats Taraldsvik]

Hi Stefan,

vcpkg very recently got a registries feature, so you can avoid forking
vcpkg for custom ports (either modifications of existing ports or new ones)

look here:
https://devblogs.microsoft.com/cppblog/registries-bring-your-own-libraries-to-vcpkg/

You can pin each dependency to a specific version using the versioning
feature mentioned earlier.

If you're looking for suggestions on what part of the code to start with,
maybe it is worth looking at the list of issues tagged "easy fix", although
it looks like it isn't really maintained:

Re: [QGIS-Developer] PYQGIS - Numpy array to QgsRasterLayer without writing to file first

[Benjamin Jakimow]

Hi Eric,

you might try to use a /vsimem/ path. For example, save your image to 
"/vsimem/myimage.tif" and
open it as QgsRasterLayer. I haven't tested it with gdal.Datasets, but 
it works with with ogr.DataSources.
Probably you shouldn't overwrite or delete the "/vsimem" object while 
QGIS has still a reference on it.


More details here: 
https://gdal.org/user/virtual_file_systems.html#vsimem-in-memory-files

Benjamin

Re: [QGIS-Developer] Reading NetCDF mesh data

[Saber Razmjooei]

Hi James,

Similar issue was reported on the MDAL repo:
https://github.com/lutraconsulting/MDAL/issues/155

ADCIRC netcdf appears not to be fully compliant with UGRID and hence you
get the error.

I hope this helps. If not, please open a ticket on MDAL and pass us some
example file and we can dig in deeper to find the issue.

Kind regards
Saber

yes, you'll need to add this even if you have pdal library available.
it defaults to false to avoid breaking the compilation if pdal isn't
available (and we want explicit breaks here rather than silently
compiling without pdal provider if the library isn't found).

That defaults to true anyway, so you can omit it if you want.

[QGIS-Developer] WITH_PDAL and WITH_EPT doubt

[Alexandre Neto]

Hi,

I am trying to add point cloud support to QGIS on conda-forge [0]
, but I am unsure
if I need to use
WITH_PDAL=TRUE and WITH_EPT=TRUE or just make sure PDAL is available from
the packaging repositories.

Will anything be missing if I skip these two during the compilation?

Thanks,

Re: [QGIS-Developer] Voronoi tool missing from processing, what could be wrong?

[Tim Sutton]

Hi

I made this so my previous noodling around to fix the issue are captured
somewhere:

https://github.com/qgis/QGIS/issues/41984

I guess QgsRuntimeProfiler.profile is just sweeping the exceptions under
the rug rather than letting them surface?

Ah -- that was the one!  I thought it was gdal for some reason...
flaky memory :)

We should really investigate why this caused a silent failure to show
the algorithms instead of an error...

Re: [QGIS-Developer] Voronoi tool missing from processing, what could be wrong?

[Tim Sutton]

Hi

Can you check if you have python-psycopg2 installed on your system? I had a
similar issue a month or two back which was fixed by installing it. (Thanks
for the nudge Nyall).

Reasonably so - the bulk of the required changes would all sit within
QgsLocationBasedAlgorithm , specifically in
QgsLocationBasedAlgorithm::processByIteratingOverTargetSource and
QgsLocationBasedAlgorithm::processByIteratingOverIntersectSource
(there's two code paths there, and the one called will depend on
whether its more efficient to iterate over the first or second layer
-- this dual-logic approach is why these algorithms and join by
location are much faster then the intersection algorithm as previously
discussed!). In both of these you'd basically expand out the size of
the bounding box used to request matching features via
QgsRectangle::grow (so the larger bounding box is handed off to the
underlying data provider spatial index for filtering), and then change
the "isMatch" test to use engine->distance(  ) <= buffer distance.
(Might also be worth first testing if the geometries intersect before
calculating the distance as it may be more efficient to do this, but
would need to be tested to verify.). On GEOS >= 3.9 based builds the
distance(... ) check is optimised and uses indexes, so it should be
very fast to perform this check! (As opposed to the inefficient
"buffer the geometries" approach). Basically we'd want to follow
PostGIS ST_DWithin approach, not a ST_Intersects(ST_Buffer(...))
approach.

If I was quoting for a customer I'd estimate 5 hours total for the
change, but of course YMMV.

[QGIS-Developer] Reading NetCDF mesh data

[James McManus]

Hi - I'm using QGIS 3.16.1 to read ADCIRC NetCDF Mesh file. When I open the
file it produces the following error statement:

HDF5-DIAG: Error detected in HDF5 (1.10.6) thread 139951069413888:
  #000: H5A.c line 430 in H5Aopen(): unable to load attribute info from

The file is read in properly, but do you know why I am getting this error?

Thanks

[QGIS-Developer] QGIS Select by Location, but no within a distance of

[C Hamilton]

I just had a user tell me he had to go back to ArcGIS so that he could use
the Select by Location function and specify a distance from the feature. He
could not believe that it was not available in QGIS. See

https://desktop.arcgis.com/en/arcmap/10.3/map/working-with-layers/using-select-by-location.htm

What he is looking for is the "Are within a distance of" operator. Am I
missing it in QGIS if not this is a really important operator to include. I
know you can always prebuffer the layer, but for an analyst who does this
regularly ours will go back to using ArcGIS.

Would this be fairly easy to implement?

Double check that you have the gdal python packages installed

Thanks for this,

from osgeo import gdal

just works, so I guess it is installed.

What is the value of
BINDINGS_GLOBAL_INSTALL
in your compile config?

The value is "YES"


Looks like something is not picked up with your install.

Agree


What if you run qgis 31.8 from the 'output/bin' dir in your build directory?

Behaves just the same


If all fails I would (I think) compile and set CMAKE_INSTALL_PREFIX in some 
local dir in your HOME

I did in ~/bin/qgis_/3.18/debug (for debug build):

And create a startup script like

export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
export PYTHONPATH=~/bin/qgis_/3.18/debug/share/qgis/python:$PYTHONPATH
export QGIS_DEBUG=0
# passing ALL parameters to qgis bin
# eg to be able to call a certain translation
# qgis --lang nl
~/bin/qgis_/3.18/debug/bin/qgis "$@"


Thanks, will think about this and try it.

Thank you again for your ansers. I see I have a sort of linking/library 
problem. GRASS is installed and GRASS modules are compiled but then 
these do not appear either in the menu.

Re: [QGIS-Developer] Building QGIS with Visual Studio 2019 CE and vcpkg

[Uhrig, Stefan]

Hi Benjamin,

I could reproduce the build issues with the current QGIS head. The easiest 
workaround I found was defining _HAS_AUTO_PTR_ETC globally. This will solve 
both the libspatialindex and exiv2 issue.

I defined _HAS_AUTO_PTR_ETC globally in the Visual Studio CMake Settings by 
checking “Show Advanced Variables” and adding /D_HAS_AUTO_PTR_ETC to 
CMAKE_CXX_FLAGS.

Something similar is currently done locally for exiv2 and Clang: 
https://github.com/qgis/QGIS/blob/c6699b28b20ede3f9a6627ae300a670f28312a83/src/analysis/CMakeLists.txt#L449

When I have some spare time, I’ll try to get libspatialindex 1.9.3 to vcpkg. 
The exiv2 issue will only be resolved with 0.28, and that’s not released yet.

Best regards,
Stefan

Hello Stefan.

in my local repo I updated libspatialindex\portfile.cmake to 1.9.3 by

vcpkg_from_github(
OUT_SOURCE_PATH SOURCE_PATH
REPO libspatialindex/libspatialindex
REF 1.9.3
SHA512

)

and removed the older patchfile.

However, in the end I had to give up, because MSVC did not compile Exiv2 with 
C++17.

Best regards,

[QGIS-Developer] OSGEO QGIS 3.18.0 broken?

[Jakob]

Just installed OSGEO QGIS 3.18.0 on Windows 10 on a clean machine. Now QGIS
cannot start claiming:

---
qgis-bin.exe - Entry point was not found
---
Procedure entrance point
?staticMetaObject@QgsPointCloudAttributeComboBox@@2UQMetaObject@@B was not
found in DLL-library C:\OSGEO4~1\apps\qgis\bin\qgis_app.dll. 

Installed OSGEO QGIS 3.18.0 on another Windows machine 3 days ago with no
problem.

Tried reinstall with no luck.

This is happening in a fresh install (one month old) of openSUSE

delete the profiles many times.


No clue by now, will have to keep looking.

Thanks again everyone

In my installation the Voronoi Polygon tool is missing from the
Processing menu, both from the bar (vector geometry dialog) and the
processing panel. It is also not listed in the Python console (see below
whole listing).

But, the code seems to be present in the /usr/local/share... folder,
where other plugins live as well:

localhost:/usr/local # find ./share -name *oronoi*
./share/qgis/python/plugins/processing/algs/grass7/description/v.voronoi.skeleton.txt
./share/qgis/python/plugins/processing/algs/grass7/description/v.voronoi.txt
./share/qgis/python/plugins/processing/algs/grass7/ext/v_voronoi.py
./share/qgis/python/plugins/processing/algs/qgis/VoronoiPolygons.py
./share/qgis/python/plugins/processing/algs/qgis/voronoi.py

I compile QGIS from source, things have gone smoothly every time and I
cannot see any obvious particular problem. I have tested with master a
couple of weeks ago, then 3.18.0 a couple of days ago, and moments ago
with 3.16.4 (after wiping all traces of previous installations) but the
problem persists.

Anyone has seen this? What could possibly be wrong here?

Thanks in advance,

Hernán

for alg in QgsApplication.processingRegistry().algorithms():
     print(alg.id(), "->", alg.displayName())

native:addautoincrementalfield -> Add autoincremental field
native:addfieldtoattributestable -> Add field to attributes table

With me your python code shows voronoi in the 'qgis' group instead of the 
'native' one:

qgis:voronoipolygons -> Voronoi polygons

I do have like 58 algorithms in the 'qgis' group. Are you missing all qgis 
ones? Or just voronoi?


I see, I only have the "native" ones ...




And in processing it just shows up with me (see screenie)

Some things to check:

-1- is the /usr/local/share/qgis/python/plugins/ dir in your PYTHONPATH ?

With me (installed QGIS in /home/richard/bin/qgis_/3.18/debug) these to are in 
my PYTHONPATH:
/home/richard/bin/qgis_/3.18/debug/share/qgis/python
/home/richard/bin/qgis_/3.18/debug/share/qgis/python/plugins

import sys
print(sys.path)

import sys
print(sys.path)

['/usr/local/share/qgis/python', 
'/home/hernan/.local/share/QGIS/QGIS3/profiles/default/python', 
'/home/hernan/.local/share/QGIS/QGIS3/profiles/default/python/plugins', 
'/usr/local/share/qgis/python/plugins', '/usr/lib/python38.zip', 
'/usr/lib64/python3.8', '/usr/lib64/python3.8/lib-dynload', 
'/usr/lib64/python3.8/site-packages', 
'/usr/lib64/python3.8/_import_failed', 
'/usr/lib/python3.8/site-packages', 
'/usr/local/lib64/python3.8/site-packages', 
'/home/hernan/.local/share/QGIS/QGIS3/profiles/default/python']




or is there other 'cruft' in it?

-2- is your LD_LIBRARY_PATH ok? To me (installing in my homedir), I have to add 
the debug/lib dir to my LD_LIBRARY_PATH.
adding:
export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
to my startup of qgis 3.18

I think if you install in default locations (like you do) then this should not 
be a problem, but maybe the QGIS python code can not load the right c++-libs?


Yes, I install in default /usr/local

With me your find-output looks exactly the same

With me your python code shows voronoi in the 'qgis' group instead of the 
'native' one:

qgis:voronoipolygons -> Voronoi polygons

I do have like 58 algorithms in the 'qgis' group. Are you missing all qgis 
ones? Or just voronoi?

And in processing it just shows up with me (see screenie)

Some things to check:

-1- is the /usr/local/share/qgis/python/plugins/ dir in your PYTHONPATH ?

With me (installed QGIS in /home/richard/bin/qgis_/3.18/debug) these to are in 
my PYTHONPATH:
/home/richard/bin/qgis_/3.18/debug/share/qgis/python
/home/richard/bin/qgis_/3.18/debug/share/qgis/python/plugins

import sys
print(sys.path)

or is there other 'cruft' in it?

-2- is your LD_LIBRARY_PATH ok? To me (installing in my homedir), I have to add 
the debug/lib dir to my LD_LIBRARY_PATH.
adding:
export LD_LIBRARY_PATH=~/bin/qgis_/3.18/debug/lib/:/usr/lib/grass78/lib/
to my startup of qgis 3.18

I think if you install in default locations (like you do) then this should not 
be a problem, but maybe the QGIS python code can not load the right c++-libs?

Yes, I just forgot to add that to the description below.

In my installation the Voronoi Polygon tool is missing from the
Processing menu, both from the bar (vector geometry dialog) and the
processing panel. It is also not listed in the Python console (see
below
whole listing).

But, the code seems to be present in the /usr/local/share... folder,

./share/qgis/python/plugins/processing/algs/qgis/voronoi.py

I compile QGIS from source, things have gone smoothly every time
and I
cannot see any obvious particular problem. I have tested with
master a
couple of weeks ago, then 3.18.0 a couple of days ago, and moments
ago
with 3.16.4 (after wiping all traces of previous installations)
but the
problem persists.

Anyone has seen this? What could possibly be wrong here?

Thanks in advance,

[QGIS-Developer] Voronoi tool missing from processing, what could be wrong?

I wrote about this a few days ago in the user list but I still have the 
problem and can find neither a cause nor a solution. I thus post it in

whole listing).


But, the code seems to be present in the /usr/local/share... folder,
