I have a number of header search paths in my project that worked up
until Xcode 2.0 but seem to have been broken by Xcode 2.1. They
refer to source trees by name, and since the directories referred
to by the source tree references have spaces in them I've included
quotes in the header paths. So in order to work they need to look
*exactly* like this in the Header Search Paths setting:
"$(SpriteWorld)/BlitPixie/Headers"
Without the quotes all versions of Xcode put this sort of thing in
the compiler command-line in place of a single -I path:
Problem #1:
When the paths are specified as above in the Target properties then
the build succeeds. However they are completely ignored when I
include them in the Project properties.
Make sure you don't have an empty "Header Search Paths" setting in
the target build settings. If the "Headers Search Paths" build
setting is bold in the target build settings, but the value is empty,
then you have the header search paths set to "" at the target level.
Problem #2:
I tried editing the search paths using the "Edit" button in the
Build properties window and including the quotes in each field. But
when I do that the quotes are \"escaped\" when placed into the
build properties and also subsequently in the gcc compile command.
This causes the quotes to be taken literally and it breaks the
compile.
I don't think you need to put the quotes in when entering the items
through the edit sheet.
Problem #3:
Even though I've entered the search paths by typing them exactly as
I've shown above, when I close the project and reopen it the quotes
in my search paths are automatically removed by Xcode 2.1. No prior
version of Xcode did this.
Yes, you have run into a known bug in Xcode 2.1 :(
I thought perhaps the use of quotes was no longer a supported
method of protecting spaces in pathnames, so I tried escaping the
spaces in the paths of the global Source Trees. However Xcode
escapes the backslashes in the Source Tree path when handing it to
gcc and then the compile breaks even more creatively:
For the -I parts gcc gets this passed to it, and the quote
placement seems wrong to me:
Am I missing something, or does this represent a bug in Xcode 2.1?
At least #3 is a known bug in Xcode 2.1, not sure about #1 and #2.
