I have a couple of questions about project preferences in Xcode 3.1.
Some of these pertain to 3.0 as well, so they can be discussed here
without any issues,
1. In general, when you build a static library, that links with
other static libraries, one must be sure, that they have same
settings.
I'm trying to make some order in projects and generally when I moved
my projects to 3.0 everything was compiling and linking. In 3.1 the
mess has started: I see in the projects, that the architectures
setting has been changed. Previously you could say 32-bit or 64-bit.
Now it's a Native architecture of build machine, I build on MacBook.
Does it mean, that my project will build for 32 or 64? (I know I can
change it to 32-bit universal)
The Release Notes discuss this.
2. Warnings: Seems, that compiler ignores warning flags, that says
not to warn about deprecated functions and I end up the compilation
with some 5000 warnings about using deprecated functions. Is there
another way to turn off this warning?
Could you be more specific about what build setting you're setting to
do this, and what warnings you're actually getting? The traditional
way to ask such a question is to open the full build transcript and
copy the CompileC invocation and its warnings output and post that to
the list.
3. When you try to change some setting in the end of the settings
window (say uncheck deprecated functions box), it jumps to the top
and it's very confusing.
Please file a bug at http://bugreporter.apple.com
4. Schedule instructions: for some reason some of my projects got
PowerPC G5 instruction scheduling setting and some PowerPC G4. Can
somebody elaborate on this? Do I need it at all, it comes as a
default. I know in CodeWarrior, we would turn it off as this feature
along with other optimizations were disturbing debug sessions.
It's best to leave this at its default setting unless you specifically
know what you're doing.
5. Fix & Continue: Does it automatically turns on a Zero Link? Is
there a setting for zero link at all, I didn't find it. Is there a
way to turn off zero link at all?
This was answered earlier; as of Xcode 3.0, ZeroLink has been
discontinued as the linker is faster.
