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://webkeks.org/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 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 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-descriptor
If you are getting errors from the assembler about instructions being
unavailable for the architecture, you need to set `OBJC` to this:
clang -arch armv6 -mfpu=vfp
Using these flags, ObjFW was compiled successfully for Android and the
Raspberry Pi.
