Hi,
I am using Eclipse to edit the files, and I used it to debug with gdb as
well (but I went back to gdb on the command line, Eclipse GDB UI is just
too slow and buggy for me ..).
You need to exclude the clang preprocessor/.. stress tests from the
sources, otherwise the indexer will freeze Eclipse. You should also
remove some autogenerated CMake project subdirectories, otherwise your
files will be opened multiple times when navigating the sources, which
*will* cause you to loose/overwrite changes when you save.
Be aware that building the project will rerun CMake if you make any
changes to the CMake files, which will regenerate your Eclipse project
files, i.e., your Resource Exclusion settings will be lost, i.e., the
indexer will get stuck the next time again. You could maybe save the
project files to a different directory, I personally just disabled
building the project in Eclipse (I use a build directory separate from
the Eclipse cmake build dir).
Here is basically how I set up my Eclipse project:
- Use File->Import->General->Import Existing Project. Do not check Copy
Sources.
- Setup Resource->Resource Filters in Project settings on project root,
- Exclude */clang/test and */clang/INPUTS project relative paths
(recursive)
- Do not use 'Location', causes nullpointer exception on file save
Make sure Indexer does not run before you create the filters!
- Delete the [Targets] and [Subprojects] directories (or whatever
they are called)
- Setup project settings:
- Setup coding style to new derivative from GNU, edit line-breaks
settings
- Setup Project Include-path settings: add following paths and defines:
- /usr/include
- /usr/include/c++/4.6
- /usr/include/c++/4.6/x86_64-linux-gnu
- /usr/include/x86_64-linux-gnu
- GET_REGINFO_MC_DESC, GET_REGINFO_HEADER,
GET_REGINFO_TARGET_DESC, GET_ASSEMBLER_HEADER,
GET_MATCHER_IMPLEMENTATION
- Setup Texteditor Font to Deja Sans Mono or any other font that
has same character width for normal and bold text!
- Setup dictionary for 'C++ Spell Checker'
General spell checker dictionary does not remember words.
For debugging, you might want to consider the 'GDB (DSF)' launcher,
which supports pretty printing. However, I found this way of running GDB
a bit unstable (You may need to restart Eclipse if your Variable view
stays empty during debugging), and back then I had some problems when
compiling LLVM/clang as shared libraries.
I made some initial efforts to create GDB pretty printing python scripts
similar to STL pretty printing for the LLVM containers. It is far from
complete, but it has initial support for some of the most common
containers. I had some problems with pretty printing for STL in the past
when I compiled LLVM with clang, but I think it works now with the
latest clang/LLVM/gdb versions.
You can find my code for pretty printing for GDB for LLVM together with
some infos on how to setup Eclipse for debugging here, if you want to
give it a go:
https://github.com/t-crest/patmos-llvm/tree/master/utils/gdb
Basically, you need to check out the 'python' folder somewhere, check
out the 'gdbinit' file, modify the paths to your system and make your
gdb load the gdbinit file (beware, the Eclipse Standard Process launcher
and the GDB (DSF) launcher seem to behave differently regarding whether
they load the ~/.gdbinit file by default or not).
Cheers,
Stefan
