Cedet is a nice tool suite but in default configuration it has some difficulty locating included files.
I would like to make it look for a directory called include/ in each parent directory and get the file from there.
for examplme a file /home/fakedrake/my-project/some-thing/something-else/file.c has #include "file.h"
file.h is in some-thing/file.h but cedet fails to locate it
What would be awesome would be to make cedet look for file.h to create completions in directories
/home/fakedrake/my-project/some-thing/include/
/home/fakedrake/my-project/include/
( and i could live with it if it tried to look for
/include/
/home/include/
/home/fakedrake/include/
)
You can use EDE for it. Moreover, it allows you to specify different include paths for particular projects. EDE is a part of Cedet, so you needn't install anything.
The basic setup is:
(global-ede-mode t)
Then for each project you should have something like that:
(if (file-exists-p "~/dev/chanconf/Makefile")
(ede-cpp-root-project "chanconf"
:name "Channel Config"
:file "~/dev/chanconf/Makefile"
:system-include-path '("/usr/include"
"/usr/include/boost")
:include-path '("/src"
"/test/gtest/include")
:spp-table '(("BOOST_PROGRAM_OPTIONS_DECL" . ""))))
It's not exactly what you're asking for since you still have to list all the include directories. But usually it's done only one time per project and doesn't require too much effort, so I hope it helps.
An article on Cedet by Alex Ott is a pretty good source of ideas if you need more.
