Re: [gdal-dev] Gdal/Proj builds on iOS

2022-09-19 Thread Peter Petrik

Hi Philippe,

iOS links all the stuff statically, so there are sometimes clashes of
symbols. You can look at how we build it for Mergin Maps here:
https://github.com/MerginMaps/input-sdk/tree/master/ios/recipes

[gdal-dev] Gdal/Proj builds on iOS

2022-09-19 Thread Philippe Lelong

Hi,


We have a strange issue with our GDAL build for iOS (GDAL 3.4.1, PROJ6). 
Everything is fine when running on iOS 15 or 16, but when the same app is run 
on iOS 14 or 12 the app will not load at all (does not even reach main) and the 
only thing I can see in a console is this:


dyld: Symbol not found: __ZTTNSt3__114basic_ifstreamIcNS_11char_traitsIc


If I remove completely GDAL libs from the app it works, so I know this is a 
dependency coming for GDAL, and a grep "char_traits" in all our libs returns 
libgdal.a and libproj.a only.


I can join more logs from configure or build if needed.


Any idea what is wrong here ?


Thanks

Philippe.

I have, it does not help if the journal mode is WAL. 

ogrinfo 
/vsicurl/"http://localhost:8060/SuomenHallinnollisetKuntajakopohjaisetAluejaot_2022_10k.gpkg";
 -ro
ERROR 1: unable to open database file: this file is a WAL-enabled database. It 
cannot be opened because it is presumably read-only or in a read-only directory.

'man ogrinfo' includes the option:
-roOpen the data source in read-only mode.

So, have you tried
ogrinfo -ro /vsicurl/MY_FILE_URL
?

Could you write a server side script that runs the ogrinfo command with r/w
rights to the upload directory?

Aihe: Re: [gdal-dev] (no subject)

Oh no! We use ogrinfo to check the file type, as these files are uploaded by
other users into a GCS bucket.
We don't apply any change to these files, as we just check them with ogrinfo to
perform other operations afterwards, so that's why we can't change the journal
mode before executing the ogrinfo command.
If there's no way that we can complete this without modifying it, we'll think
about an alternative solution!

Thanks so much for your help!

Hi,

What do you mean by processing? Http users cannot edit anything in any case. Do
you edit the GPKG file locally at the same time? "Immutable" could be a
solution if GDAL can support it somehow, but if the database is edited at the
same it does not feel right. Taken from the SQLite documentation:
"immutable: The immutable parameter is a boolean query parameter that indicates
that the database file is stored on read-only media. When immutable is set,
SQLite assumes that the database file cannot be changed, even by a process with
higher privilege, and so the database is opened read-only and all locking and
change detection is disabled. Caution: Setting the immutable property on a
database file that does in fact change can result in incorrect query results
and/or SQLITE_CORRUPT errors. See also: SQLITE_IOCAP_IMMUTABLE."

Do you have some good reason not to change the pragma?

Hi Jukka,

Thanks so much for taking a look at this! We already tried to change the
journal mode, and it works as expected, but we would like to know if there is
any way of processing this files without changing anything on the file.

Hi,

Read
https://www.sqlite.org/wal.html.
I suggest to change the journal mode into the default mode before inserting
the GPKG file into server. How to: Execute "PRAGMA journal_mode=DELETE". I
tested that it will now work:

INFO: Open of
`/vsicurl/http://localhost:8060/SuomenHallinnollisetKuntajakopohjaisetAluejaot_2022_10k.gpkg'
using driver `GPKG' successful.
1: Aluehallintovirasto
2: Valtakunta
3: Maakunta
4: Kunta

If the GPKG file in WAL mode is already placed on the server it might be
possible to open it somehow as "immutable". I do not know how to do that with
GDAL.
