ObjFW is a portable, lightweight framework for the Objective C language. It enables you to write an application in Objective C that will run on any platform supported by ObjFW without having to worry about differences between operating systems or various frameworks that you would otherwise need if you want to be portable.

See https://heap.zone/objfw for more information.

Installation

To install ObjFW, just run the following commands:

$ ./configure
$ make
$ make install

In case you checked out ObjFW from the Git repository, you need to run the following command first:

$ ./autogen.sh

Building as a macOS or iOS framework

When building for macOS or iOS, everything is built as a .framework by default if --disable-shared has not been specified to configure.

To build for iOS, use something like this:

$ clang="clang --sysroot $(xcrun --sdk iphoneos --show-sdk-path)"
$ export OBJC="$clang -arch armv7 -arch arm64"
$ export OBJCPP="$clang -arch armv7 -E"
$ export IPHONEOS_DEPLOYMENT_TARGET="10.0"
$ ./configure --prefix=/usr/local/ios --host=arm-apple-darwin

To build for the iOS simulator, use something like this:

$ clang="clang --sysroot $(xcrun --sdk iphonesimulator --show-sdk-path)"
$ export OBJC="$clang -arch i386 -arch x86_64"
$ export OBJCPP="$clang -arch i386 -E"
$ export IPHONEOS_DEPLOYMENT_TARGET="10.0"
$ ./configure --prefix=/usr/local/iossim --host=i386-apple-darwin

Using the macOS or iOS framework in Xcode

To use the macOS framework in Xcode, you need to add the .frameworks to your project and add the following flags to Other C Flags:

-fconstant-string-class=OFConstantString -fno-constant-cfstrings

Optionally, if you want to use blocks, you also need to add:

-fblocks
