Errors building for iOS on mac

[tigrenok00]

Hi,
I'm trying to build the latest version code as arm64 ios library (to use when compiling tesseract for the same purpose) on M2 mac.
I'm getting this error:
../../prog/xtractprotos.c:198:15: error: 'system' is unavailable: not available on iOS`

Also, there are many warnings like these:
"ld: warning: building for iOS, but linking in dylib file (/opt/homebrew/Cellar/jpeg-turbo/2.1.5.1/lib/libjpeg.dylib) built for macOS"
Are all these libs should be prebuilt for iOS as well, or is okay to leave like this? I want to get a static library and not dynamic...

This is my script:

#!/bin/bash

OPT_FLAGS="-O3 -g3"
MAKE_JOBS=16

dobuild() {
make clean
export CC
CC=$(xcrun --find --sdk "${SDK}" gcc)
export CXX
CXX=$(xcrun --find --sdk "${SDK}" g++)
export CPP
CPP=$(xcrun --find --sdk "${SDK}" cpp)
export CFLAGS
CFLAGS="${HOST_FLAGS} ${OPT_FLAGS}"
export CXXFLAGS
CXXFLAGS="${HOST_FLAGS} ${OPT_FLAGS}"
export LDFLAGS
LDFLAGS="${HOST_FLAGS}"
../configure --host="${CHOST}" --prefix="${PREFIX}" --enable-static --without-curl --disable-shared
make -j"${MAKE_JOBS}"
make install
}

SDK="iphoneos"
ARCH_FLAGS="-arch arm64"
HOST_FLAGS="${ARCH_FLAGS} -miphoneos-version-min=8.0 -isysroot $(xcrun --sdk ${SDK} --show-sdk-path)"
CHOST="arm-apple-darwin"
PREFIX="${HOME}/git_projects/leptonica/output/DEVICE_ARM"
dobuild

And this is the full output and the error:

To be clear, I am not an expert in buildilng on iOS. I've never done it.

You are getting this message:
../../src/boxbasic.c:2233:15: warning: 'open_memstream' is only available on iOS 11.0 or newer [-Wunguarded-availability-new]
if ((fp = open_memstream((char **)pdata, psize)) == NULL)
^~~~~~~~~~~~~~
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS16.4.sdk/usr/include/stdio.h:367:7: note: 'open_memstream' has been marked as being introduced in iOS 11.0 here, but the deployment target is iOS 8.0.0
FILE *open_memstream(char **__bufp, size_t *__sizep) __API_AVAILABLE(macos(10.13), ios(11.0), tvos(11.0), watchos(4.0));

If you look in environ.h, HAVE_FMEMOPEN is defined to be 1 for iOS => 11.0, whereas yours apparently is 8.0. So it shouldn't be defined and those functions -- open_memstream() and fmemopen() -- should not be exposed.

Also, at the end note that the repeated ld warnings are like this:

ld: warning: building for iOS, but linking in dylib file (/opt/homebrew/Cellar/webp/1.3.0_1/lib/libwebpmux.dylib) built for macOS

Hi, I changed to -miphoneos-version-min=11.0 and now not getting the error about open_memstream, but this still shown:

../../prog/xtractprotos.c:198:15: error: 'system' is unavailable: not available on iOS
ret = system(buf); /* cpp */

The files in prog are for testing and code examples, so you can simply ignore those errors. The library build is not affected by them. Ideally the code which does not work for iOS should be protected by a conditional compilation. Or the build rules could skip the prog build for iOS completely. If you want, you can create a fix and contribute it as a pull request.

Thank you! I got it working.
Here is the script I used in the end if it helps anyone:
