Why No Project File?
• Xcode project file writes FSRef
hexadecimal values in project file.
– maybe to prevent “missing a source file
because it is moved to somewhere”.
– the portability is slightly
questionable.
• It is hard to guarantee that it
works with various versions of
Xcode.
• Feedback is welcomed:
– [email protected]
– public comment can be posted to
freetype mailing list.

Start Xcode
Usually located at /Developer/Applications/Xcode
Some versions show “welcome window”, or “wizard
window”, or nothing, please don’t care and close it.

4
Select Project Template
The might be some default, but...
Even if you’re going to build iOS library, selecting “Mac OS X”
→ “Static Library” → “BSD Static Library” is recommended.

Name and Locate the Project
“Save As”: If you want to
build libXXX.a, naming
“XXX” is recommended.
“Where”: You must
select the folder of
freetype2 source code,
including “builds”,
“devel”, “include”, “src”,
etc.

Skelton is Prepared
From the name of project, the
default library name is set
automatically. You can change it.

Register “module” Source
Register the “module”
sources from “Finder”, as
you did for “base”. You
must gather them from
multiple folders, so you
cannot finish it by single
Drag’n’Drop. You must do
many times. The list of the
“base” sources is shown in
next slide.

named $(project_name)/build/$(target)/

Limitation in Xcode Development
•
You cannot build universal binary at once.
– Unix style building can do that.
– You have to build binaries for each architectures
and combine them.
•
You cannot build shared library for iOS.
– Unix style building can do that.
– Even if SDKs supports it, (some versions of) iOS
addon for Xcode does not provide project template.
•
You cannot build archive and shared library by
same project.
– Unix style building can do that.
– As you were forced to select shared or static
library from the template, you cannot build both
library at once.
•
You cannot hide private symbols.
– Unix style building can do that, and it prevents
your applications from referring private symbols of
FreeType2 and guarantee the binary compatibility.
