I want to use it in iOS or Android but I can't compile

I want to use it in iOS or Android but I can't compile，please give a tip, thanks.

I have compile it, and generate libjson-c.a, libjson-c.4.dylib and ect，but it can't run iOS or macOS(10.14+).

file was built for archive which is not the architecture being linked (x86_64): /Users/man/workspace/libjson-c.a Undefined symbols for architecture x86_64: "_json_object_from_file", referenced from:

Can you compile, or can't you?
Are you trying to run on iOS? Or Android? Or macOS?
It sounds like you're pretty confused as to what you're trying to do, and until you sort that out you're going to have a hard time getting help from anyone.

btw, building on macOS (using the standard instructions) or Android (using the instructions in Android.configure.mk), should work fine, though I personally haven't tried either.
I've not heard of anyone trying to build on iOS. That's not to say it doesn't work, but you might be on your own there.

This is the result file.
I want to add 'libjson-c.a' into project for iOS project, but the project compile error as follow

Now I use json-c with source and add to xcode for ios, It's ok.

How to do when I want to use 'libjson-c.a'?

[veryitman]

And use your way what compile the json-c, it supports x86_64 only.

If you want to link and run on an ARM iOS device, you need to use the iOS cross-compiling toolchain, which is included in Xcode somehow. This is a complicated topic which is not really the responsibility of libevent.

@ploxiln
I write a shell file that is a cross-compilation, it generate a libjson-c.a for x86_64 but it happends error allways.

Can you understand what I say?

[ploxiln]

x86_64 is the architecture of your macOS laptop, but not of your iOS phone/tablet, so it doesn't work for iOS phone/tablet

[veryitman]

I get you. But even you run make and make install to compile the source, it doesn't support macos' project that happends error. In words, I can't use the *.a file at macos or iOS etc.
