CEDET

Greetings

  After dealing with some issues via email, and some C++ code at work,
I devised a way to automatically query GCC to setup some of the more
confusing aspects of getting the Semantic C parser working.

  If you get the latest version from CVS, along with a wide range of
various bug fixes from the past couple weeks, you will find
`semantic-gcc.el'.  It isn't in the build harness yet (I'll get
there), but you could add this to your .emacs file:

  (require 'semantic-gcc)
  (semantic-gcc-setup "gcc")

where "gcc" is optional, or could specify your favorite gcc command.

On linux (where I tested) it will setup include paths and core macros
so all your system and STL headers will get parsed correctly.  Huzzah!

  I haven't been able to give it wide testing, so if you try it, be
sure to run the config, load up a c++ file, and do:

C-h v semantic-gcc-setup-data RET
 - Does the value here make sense?

M-x semantic-decoration-all-include-summary RET
 - Has it setup your include paths correctly for c++?

M-x semantic-lex-spp-describe
 - Has it added many mysterious macros into your macro table?

Since it is parsing the output of GCC, there are likely some hiccups.
Unusual output strings, or patches for those strings would be welcome.

Thanks!
Eric

Re: [CEDET-devel] New gcc setup support in CEDET From: Alex Ott <alexott@gm...> - 2008-08-27 06:42 Hello thanks for your work. I installed this package and try to use it. After loading of my source file, i asked semantic-gcc-setup-data and got following value semantic-gcc-setup-data is a variable defined in `/home/ott/projects/emacs/emacs/cedet/semantic/bovine/semantic-gcc.el'. Its value is ((version . "posix")) I think, that this is bad result? my gcc -v outputs following data: Using built-in specs.

Re: [CEDET-devel] New gcc setup support in CEDET From: Eric M. Ludlam <eric@si...> - 2008-08-27 13:23 Hi all, Thanks for the patch and output of gcc -v! Using the provided output, plus several other outputs from some machines I have access to, I created a test procedure, and used a variant of your patch to get things working across more machines. I've checked in these changes, so they should be available on the anonymous server soon. For those who haven't tried using semantic-gcc-setup yet, if it doesn't work, send me your gcc -v output, or try adding support for it yourself. Thanks again Eric >>> David Engster <deng@...> seems to think that: > >Alex Ott <alexott@...> writes: >> Its value is ((version .

Re: [CEDET-devel] New gcc setup support in CEDET From: Eric M. Ludlam <eric@si...> - 2008-08-28 02:01 Hello agian, In addition to various fixes posted here, I've checked in changes to automatically run the GCC setup program along with the regular semantic C support if you are on one of OSes that typically use GCC. If you want to direct the gcc setup system to use a different version of gcc besides "gcc", you can do this in your .emacs file: (semantic-gcc-setup "my-gcc") and it will initialize things so that the regular GCC isn't used. To help folks validate everything, I also added a new command: M-x semantic-c-describe-environment to help provide debug output if things don't work as planned. Check it out, and let me know if there are any problems. I'd be glad to know of grand success as well. :) If you use one of the other languages supported by semantic parsers and want to add something similar, let me know. I'll work with you to get something up and running. Thanks Eric >>> "Eric M.
