My app compiled and ran on 10.3.
It compiles and runs on 10.4.
I'm trying to make compatibility build.
It runs on 10.4 but crashes instantly with EXC_BAD_ACCESS on 10.3.9
(trying to instantiate the application delegate from the main nib).
After a review of the docs and the archives...
I've got the Deployment Target set to 10.3.
I've got the SDK set to 10.3.9.
I read the docs again. Perhaps this is my problem:
For each target, supply a prefix file that takes into account the
selected SDK. To use an umbrella framework header from an SDK as
your prefix file, add the appropriate #include <Framework/
Framework.h> directive to your target's prefix file, instead of
setting a Prefix Header path to the umbrella framework header
directly.
I seem not to have a prefix file (or it is very well hidden). I
would dearly love to supply one and get on
with things but...
What is it ? What's in it and in what form ? Do I order one from
the ACME company ?
The only mention of the phrase "prefix file" in the entire 452 page
Xcode manual is in the above paragraph.
What do I have to do do learn the secret handshake ?
The prefix file is a header that the system automatically includes at
the top of every file it compiles. You set the prefix file (a.k.a.
Prefix Header) in the build settings for your project, target, or
configuration.
