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:
$ autoreconf
Building as a Mac OS X framework
================================
It is also possible to build ObjFW as a Mac OS X framework. To do so,
just execute `xcodebuild -target ObjFW` in the root directory of ObjFW
or open the .xcodeproj in Xcode and choose Build -> Build from the
menu. Copy the resulting ObjFW.framework to `/Library/Frameworks` and
you are done.
Using the Mac OS X framework in Xcode
=====================================
To use the Mac OS X framework in Xcode, you need to add the .framework
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
Building with LLVM/Clang for ARM
================================
When using LLVM/Clang older than 3.5 to compile for ARM, it is necessary to
specify extra flags in order to enable ARM EHABI compliant exceptions. To do
so, set `OBJCFLAGS` to this:
-O2 -g -mllvm -arm-enable-ehabi -mllvm -arm-enable-ehabi-descriptors
If you have a CPU supporting VFP or NEON, it is important to set the correct
architecture, as otherwise VFP / NEON registers won't be saved and restored
when forwarding. For example, if you have an ARMv6 that supports VFP, you
need to set `OBJC` to this:
clang -march=armv6 -mfpu=vfp
Using these flags, ObjFW was compiled successfully for Android and the
Raspberry Pi.
