Hi,

I'm using IPSec features on Linux (redhat 2.6.xxx) I'm doing include of "pfkeyv2.h" and some other IPsec related files. Now these files are part of rpm 2.6.9-11.EL-i686 on one my linux host and rpm 2.6.9-5.EL-i686 on other linux host. Thus after installing correspondent rpms on one host I need to give the compiler the directory
-I/usr/src/kernels/2.6.9-11.EL-i686/include
and
-I/usr/src/kernels/2.6.9-5.EL-i686/include
on the other host.
Of course I want to compile with the same makefile on all hosts. Now the question is how I merge the contents of
/usr/src/kernels/2.6.9-11.EL-i686/include
to the standard /usr/include directories.
Thanks,
Rafi

Well, you could make symlinks in /usr/include to the IPsec kernel headers, but having kernel headers in /usr/include for user programs isn't advocated or promoted and definitely discouraged.

I would suggest dealing with this in the makefile and have a macro for the kernel release so your gcc flag reads something like:

CFLAGS=-I/usr/src/kernels/$(KERNELVERSION).EL-i686/include

Then set KERNELVERSION to 2.6.9-11 or 2.6.9-5 in the makefile. Or you could do it through the environment, like this:

$ KERLNELVERSION=2.6.9-11 make blah

You get the idea.

Peace...
