I get exactly the same layers in /ogrinfo/ as I do with your
program both with GDAL 3.3.2 and GDAL 3.4.1 on all of your S57 files.
/s57/1B5X02NE.000/ has 13 layers.
Here is the program I used: https://pastebin.com/z99xeQ92

The S57 file we used to test with each language and it is read
correctly in C# & python, our c++ project is the problem. The S57 is
the one generated in "\gdal-3.4.1\autotest\ogr\data\s57" when we built
gdal. But here is a link
<https://drive.google.com/file/d/1AGCHEQMWHvs6IJgDW45KJvK6gm-r_cpH/view?usp=sharing>
to that s57 folder.
The specific s57 file we used was "1B5X02NE.000" which in reference to
the first image I linked should have 13 layers.
Thanks in advance for the help!

I’m an S57 expert. Send me the data - I’ll take a look, there’s a lot
of leeway with S57 and sometimes it trips up GDAL. I had issues with
AML data before which is similar…

Your code looks OK, can you send me the file too?

Here is the C++ code we have written to read the test s57 file.

We feel that it is some setup stuff we have missed but can't
find any clear information. For example we hadn't seen
GDAL_DATA environment variables mentioned in any of the
documentation we've tried following until Even mentioned it.
Are there any other setup stuff we need to do?

Can you post your C++ code? Generally, you have more chances
of getting an answer for this type of question on

Hi,
So I am trying to get a test C++ project built to read S57
files using the gdal/ogr C++ library.
I have previously used the C# library that is on there
NuGet manager which states v2.4.4 and that seems to read
the s57 without issues. Also tried python and that seems
to read it with no issues.
However, I am having a problem with the C++ test project.
Having built the C++ library into the .lib and .dll files
I have included them into a blank project and implemented
the functions to read the s57 file, however it is only
reporting 5 layers.
These 5 layers are the same no matter the s57 file. And 4
out of those 5 layers are not actually layers.
Using the autotest generated s57 file as a unit test to
cross check, there is supposed to be 13 layers.
Note: I had feedback from Even indicating the setup
environment is probably wrong. And to set up the GDAL_DATA
environment variable, so we've made an environment
variable referencing the gdal/data folder and that hasn't
fixed the problem, but I think it's on the right track as
Even said they could reproduce the problem if not setup
correctly.
*Has anyone had success reading s57 files with a C++
3.4.1. project that could possibly help get this going?*
