Thanks Peter,
I have tried various combinaisons of "rename-internal" symbols and
hide-internal-symbols yes/no and with/without png and some other guesses but
couldn't fix it.
Here is my current configure (for iOS Simulator, works great on iOS 15 or 16,
but not on iOS 12 or 14).
./configure --prefix=/Users/philippelelong/Documents/gdal/gdal_ios_simulator \
--disable-shared --enable-static \
--without-sqlite3 \
--without-ld-shared \
--without-libtool \
--with-threads \
--without-geos \
--with-libz=internal \
--with-libtiff=internal \
--with-geotiff=internal \
--with-expat=/Users/philippelelong/Documents/libexpat-R_2_4_8/expat/expat_ios_simulator
\
--disable-all-optional-drivers \
--enable-driver-bsb \
--enable-driver-iso8211 \
--enable-driver-s57 \
--enable-driver-shape \
--with-png \
--with-jpeg=no \
--with-curl=no \
--with-sqlite3=no \
--with-hide-internal-symbols=yes \
--with-proj=/Users/philippelelong/Documents/gdal/proj6_ios_simulator

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:

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_traitsIcEEEE
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.
