RE: [cdt-dev]Questionabout ICSettingEntry.INCLUDE_FILEandICSettingEntry.MACRO_FILE
|
I see the problem now. I had the indexer turned off for the project.
So the file itself was found but the buffer for it was empty because it
couldn't locate the file in the index.
After digging around in the code a bit, I found that I could turn on the
"Follow unindexed header files when producing the outline view" option
in the C/C++ preference page, and then it would parse the macro file
correctly.
Is this the expected behavior? Perhaps we should change the label in
the pref to be more explicit? Or maybe that should be the default
behavior when the indexer is disabled?
Thanks,
Warren

ICSettingEntry.INCLUDE_FILEandICSettingEntry.MACRO_FILE
Hi Warren,
most likely the problem is that the files you are specifying are not
found on the include search path. The difference between macro- and
include-files is that macro files are preprocessed only (i.e. macro
definitions are extracted) whereas include files are actually parsed
(i.e declarations are extracted also).
These options should work just like the gcc's -imacro and -include
commandline options.
Markus.
