Hi Nik,
You may try alternative build scenario using CMake.
1. Install XCode command line tools if already not done this
(https://www.embarcadero.com/starthere/xe5/mobdevsetup/ios/en/installing_the_commandline_tools.html)
and CMake (https://cmake.org/download/)
2. In terminal execute commands:
> git clone --depth 1 https://github.com/nextgis-borsch/lib_gdal.git
> cd lib_gdal
> mkdir build
> cd build
> cmake -G"Unix Makefiles" -DBUILD_TARGET_PLATFORM=IOS
-DCMAKE_INSTALL_PREFIX=install -DCMAKE_BUILD_TYPE=Release
-DENABLE_BITCODE=OFF -DIOS_ARCH=arm64 -DIOS_PLATFORM=OS -DENABLE_NEON=ON
-DCMAKE_TOOLCHAIN_FILE=../cmake/ios.toolchain.cmake -DWITH_JSONC=ON
-DWITH_JSONC_EXTERNAL=ON -DWITH_TIFF=ON -DWITH_TIFF_EXTERNAL=ON
-DWITH_GeoTIFF=ON -DWITH_GeoTIFF_EXTERNAL=ON -DOSX_FRAMEWORK=ON
-DENABLE_GIF=OFF -DENABLE_CAD=OFF -DENABLE_PNG=OFF -DGDAL_BUILD_APPS=OFF
-DGDAL_BUILD_DOCS=OFF -DWITH_PYTHON=OFF ..
Some flags description:
-DIOS_ARCH maybe armv7, armv7s, arm64, i386 or x86_64
-DIOS_PLATFORM maybe IOS or SIMULATOR
After configuring you will see summary about GDAL build or error
message. I expect everything will be fine.
Run this command to build GDAL:
> cmake --build . -- -j 4
May be this need to rerun twice as dependency may not build on first run.
You may build GDAL for several architectures and create fat library
using lipo -create command (I rewrite OpenCV py script to automate
creating my own fat iOS library which use GDAL -
https://github.com/nextgis/nextgis_datastore/blob/master/opt/ios/build_framework.py)
This is minimal build of GDAL. If you need some drivers which not build
by listed command let me know - I'll help to modify command line options.
Best regards,
Dmitry

Hi Even,
If I include the -Wall option, then I do get just the one warning. Here’s the
command line I’m using, which is based on similar command lines from the make
output…
------------------------------------
$ /Applications/Xcode.app/Contents/Developer/usr/bin/gcc -o conftest -arch
arm64 -pipe -Os -gdwarf-2 -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.1.sdk
-Wno-implicit-function-declaration -fembed-bitcode -mno-thumb -Wall -arch
arm64 -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS11.1.sdk
conftest.c -ldl
conftest.c:1:24: warning: unused variable 'off' [-Wunused-variable]
int main() { long long off=0; }
^
1 warning generated.
$
——————————————————
I made the change you suggested to acinclude.m4 and then ran autoconf. Then I
attempted to build GDAL again, but got the same error:
--------------------------------------------------
geotiff.cpp:7653:13: error: unknown type name 'GUInt64'
typedef GUInt64 WordType;
^
1 error generated.
make[2]: *** [../o/geotiff.lo] Error 1
make[1]: *** [gtiff-install-obj] Error 2
make: *** [frmts-target] Error 2
--------------------------------------------------
I have to admit that I’m a very small-time developer and I’m somewhat out of my
depth here, so forgive me if I sound like I don’t understand some of this stuff.
Cheers,
Nik.

Hi Even,
Thanks for your reply. You are correct as usual. Your ‘cc’ test produced
no errors,
And no warnings as well ?
Weird, since this is the test that is used to dected long long presence
See m4/acinclude.m4
Do you run configure with CCFLAGS defined ? For example, if CCFLAGS="-Wall", then the test will throw a warning that will make it fail.
I'm not sure why we use CCFLAGS in that file, whereas CFLAGS is used everywhere
else.
What if you change in m4/acinclude.m4
echo 'int main() { long long off=0; }' >> conftest.c
to
echo 'int main() { long long off=0; (void)off; return 0; }' > conftest.c
and run autoconf to regenerate configure ?
Even
