so what's the problem you're seeing?

Shian-Wang commented 1 week ago

I use below the parameters and ../cmake-configure to compile for ios simulator(as below command line), but I loaded static lib in xcode project compiler failed. I can't use the lib in xcode project. xcode compiler show the error message which the lib build for macos not simulator. How to fix the bug? Any settings I miss in building lib for ios simulator?

I find the parameters to build ios simulator for json-c v17.0

as below to build ios simulator success sdk_target="iphonesimulator" ios_ver=xcodebuild -version -sdk $sdk_target | grep SDKVersion: if [[ "$ios_ver" == "" ]] then echo "Could not determine iOS SDK version. Is xcodebuild on your path?" exit 1 fi

echo $ios_ver

It seems like a common way to do this is with a toolchain file (-DCMAKE_TOOLCHAIN_FILE=path_to_your_toolchain_file) and https://github.com/cristeab/ios-cmake/blob/master/toolchain/iOS.cmake, but I guess there's more than one way to do it. I'm glad you were able to get it working.
