c++ - Emacs-24 auto-complete for cross-directory header files -

auto-complete not work emacs c++ projects have multiple modules. header files each sub-module depends on exist both in module , in other modules. in other words, 1 module may include header files of module.

below sample source code:

. ├── cmakelists.txt ├── my_inc │   ├── cmakelists.txt │   ├── myadd.cpp │   └── myadd.h ├── readme.md └── src ├── cmakelists.txt ├── hello.java ├── helper.cpp ├── helper.h └── main.cpp

the main.cpp:

#include "myadd.h" #include "helper.h" int main() { myadd add_obj; helper h; h.tostring(); // auto-complete works since helper in same directory. add_obj. // auto-complete add_obj not work // because myadd.h in directory (my_inc). }

the method list pops when type . after h, not variable add_obj, class of defined in myadd.h other module my_inc.

i have tried solutions (cedet-related):

(ede-cpp-root-project)

this solution work here. not want apply 1 since

it create .emacs big since have many projects.

:include-path here unable handle complicated header dependence of 20+ sub-modules, makes solution more toy. prefer separating configuration .emacs.

ede project

i create project , target via ede-new , c c . t, compilation instead of name, method auto-complete.

ede-generic-project

as described in solution this question , manual on ede-generic-project i'm getting error:

eieio-oref: wrong type argument: (or eieio-object-p class-p), nil

once execute:

m-x ede-customize-project ret after (ede-enable-generic-projects).

environment: utilize emacs 24.3 , installed auto-complete , cedet2.0.

step 1 when working through issues involve projects, header files , completion enable (global-semantic-decoration-mode 1) includes mechanism highlighting header files in reddish when can't found. helps in working through configuration problems.

if want maintain .emacs file clean , project support, generic project type bet, right until error started showing up. fixed in cedet bzr repository under ede-ldf branch of writing (july 14, 2014) , merged sometime soon.

if have lots of sub-modules, can rely on tool gnu global. cedet manual has short section using gnu global includes snippet need help locate files. in way, global track headers, , can used find them. if headers have unique name, set. if file "myadd.h" exists in several places, , need take "myadd.h" based on c file is, out of luck, , need custom project type that.

after each configuration change, need forced reparse of buffer headers want found caches refreshed. utilize c-u m-x bovinate ret forcefulness it.
