Hello CDT users,
I recently changed to Eclipse 3 and CDT 2.0 (on Windows XP). I did this
because I was hoping that some features I got used to during Java
development would be available in CDT 2.0 (compared to 1.2).
I encountered the following problems:
- The Content Assist does never show anything, it always times out (even
if I set the timout to very high values)
- Everytime I start Eclipse the C++-Indexer runs for a while. Does it
not safe it´s former results somewhere? I fear it will be indexing for
ages if my project grows....
Is this problem related to the Content Assist function?
- The Indexer shows an error in each file of the following format:
#ifndef __IRCONTAINER
#define __IRCONTAINER
// class definition goes here
#endif
The final #endif is "unbalanced". Why?
Well, as long there is no Content Assist working I could also use a text
editor and the command line instead of Eclipse...
Perhaps you have some hints for me where the problem could come from. I
guess CDT is not so bad as it seems to be for me at the moment :)
Regards,
Friederich

Hello David,
so the Indexer is not the problem. Is there any common error I am likely
to do that causes my Content Assist not work?
Thanks,

As I said before, I have already tried this with no result.

Yes, CDT M9 is really quite good. I use it with Eclipse 3.0 RC2. It took
me a while today to get it running with the Content Assist working. There
are two things you should do:
1. In the Project Properties of your C++ project, see "C/C++ Indexer" and
check the option "Enable Index Problem Reporting". This should really be
turned on by default, because w/o it, you never know why the Content
Assist does not work.
2. When you have turned it on, you will probably find a question mark at
some of the include directives: Could not find header file or sth similar.
Add the appropriate include paths in the Project Properties: In
"C/C++ Include Paths & Symbols", click on "Discovered Paths" and choose
"Add Include Path from Workspace..." to add local directories where CDT
can find your header files. Also, click "Add External Include Path" and
choose sth like /usr/include/c++/3.2.2. On your system, it might be sth
like c:\cygwin\include\c++\3.x.x or so. The path has to contain the files
vector, iostream, etc.
After that, Refresh, Clean, and Rebuild. It should work.
It might to help create a completely new project and start it again.
Create a new project, create a new class with the wizard.
Generally, when creating a new project, I had better experiences with the
"standard make c++ project" where I wrote my own makefile.
Here is a simple example Makefile. It takes your main.cpp file and
compiles it into main.exe:
OFILES=main.o
TARGET=main.exe
all: $(TARGET)
$(TARGET):$(OFILES)
g++ $(OFILES) -o $@
%.o: %.cpp
g++ -I. -c -o $@ $<
clean:
rm -rf *.o test

Hello Andreas,
thank you very much for this detailed reply. I will try what you proposed.
I already switched on the error reporting and got some errors that I do
not understand. I will try to get rid of them.
So far an interesting contradiction is that Dave said "Note that the
index is not used for content assist. Currently the index is
only used for search and refactor operations."
Maybe indexer errors show also the reasons of content assist confusions.
Thanks a lot

Both the indexer, and content assist use the C/C++ parser. The error
messages that the index is reporting originate in the parser. These error
messages can be used to debug both features. There is also a .log file in
the metadata directory that has these error messages (but there is a ton of
junk in there as well)
Virutally all errors in content assist that we have seen, have been related
to environmental issues -- such as include paths and predefined macros.
With the current CDT, there is still performance issues with the parser, so
content assist times of 10 sec may happen.
