xenomai-3.0.5 include path

[demon.han]

Hi,
I am working on xenomai3.0.5 with Eherlab Ethercat.
Here I got a problem.
After installing xenomai,I got 2 include directory:
1. /usr/include/xenomai
2./usr/xenomai/include
I find rtdm_driver.h in /usr/include/xenomai but out /usr/xenomai/include.
This cause a problem,I think:
when I compile Etherlab,I got error as"/master/rtdm.c:37:30: fatal error: rtdm/rtdm_driver.h: No such file or directory",
so I copy the header to /usr/xenomai/include/rtdm,and the error is fixed.
Is there another way to fix the problem?
Best Wishes.
demon.

Hi,

did you compare the two files? My guess would be that you are on a
system where a careless "make install" was run on multiple versions of
xenomai, possibly with prefix dirs set.

Once you are sure that both headers are indeed coming out of the same
installation, it would be time to look the the install target of make.

The link suggests that you are on Ubuntu. The documentation says to do
"sudo make install", which will work exactly one time ... This is
wrong, especially since you are on a debian-based distro.

Instaed you should be building debian packages and install those.
Everything you need is in the tree. Just change CONFIG_OPTS in
debian/rules, add an entry to debian/changelog and run
dpkg-buildpackage.
If you are not on debian use prefix/destdir and "xstow" and _never_
"make install" as root.

Now you should probably ask your package manager which files in /usr do
not belong to any package. And remove all that look like xenomai. After
that see if a single "make install" will get you into the same conflict
again, or the installation of the resulting package.
