finds it just fine, but #including it doesn't. If it makes any
difference, I'm working in Xcode 2.0, so it probably can't be
discussed in public. But if somebody from Apple could contact me
directly, I'd really appreciate it. My Spotlight project was able to
build in previous Tiger builds.
Unless you compile with option -nostdinc++, the compiler (or better
preprocessor) searches in standard system headers which are set
implicitly. Standard system search paths are hard wired into the
compiler and cannot be changed (but disabled via -nostdinc).
Thus, you do not need to set header search paths explicitly for
standard headers.
The command-shift-d thingy just searches in customizable predefined
search paths, which do not necessarily match any search paths relevant
for your build. These paths are orthogonal to the search paths set in
the build settings.
So a header which opens nicely in an editor via command-shift-d , might
not be the header you expect and which will be actually inlcuded by the
compiler.
IMO, this is at least confusing.
What you did experience (probably), is that the indexer will not parse
C++ headers. That means, C++ headers will not appear in the
headers-popup, nor will the symbols listed from them. The indexer will
also refuse to parse headers having uncommon file extensions.
IMHO, this is one of the various missing features. Furthermore, the
indexer gets pretty confused or just lacks to produce detailed
information when parsing C++ source code, like namespace or qualifiers
as well as templates, local classes.
