Description:I've installed kernel headers, sources, created the linux and linux-2.6 links.
I get asterisk and zaptel through svn branches/1.4
Asterisk compiles fine, while zaptel not (I just need ztdummy):

meucci:/usr/src/zaptel-1.4# make
make[1]: Entering directory `/usr/src/zaptel-1.4'
make -C /lib/modules/2.6.18-3-k7/build SUBDIRS=/usr/src/zaptel-1.4 modules

make[1]: *** [linux26] Error 2

The file is present in the system, but probably in a different location:
meucci:/usr/src/zaptel-1.4# find / -name genksyms
/usr/bin/genksyms
/usr/src/linux-kbuild-2.6.18/scripts/genksyms
/usr/src/linux-kbuild-2.6.18/scripts/genksyms/genksyms
/usr/src/linux-source-2.6.18/scripts/genksyms
/sbin/genksyms


my kernel is "vanilla" debian:
meucci:/usr/src/zaptel-1.4# uname -r
2.6.18-3-k7

meucci:/usr/src# ls -l
total 43794

can't you just create a symlink pointing to /usr/src/linux-source-2.6.18/scripts/genksyms?

The problem is not find a workaround, but the make code to be able to use debian location of sources / executables.
In any case, if I do the link:
ln -s /usr/src/linux-kbuild-2.6.18/scripts/genksyms/genksyms /usr/src/linux-kbuild-2.6.18/scripts/mod//genksyms

then I've another compilation error:
 Building modules, stage 2.
 MODPOST
/bin/sh: scripts/mod/modpost: No such file or directory
make[3]: *** [__modpost] Error 127
make[2]: *** [modules] Error 2
make[2]: Leaving directory `/usr/src/linux-source-2.6.18'
make[1]: *** [linux26] Error 2
make[1]: Leaving directory `/usr/src/zaptel-1.4'
make: *** [all] Error 2

The problem is that the script looks for executable files under the SOURCE linux directory, while, at least debian, puts them under a linux-kbuild-2.6.18 directory.
in fact:
meucci:~# find / -name modpost
/usr/src/linux-kbuild-2.6.18/scripts/mod/modpost
So, except the workaround of create another link (and then another...?), and have to update them everytime I update the kernel, I would like the makefile be able to consider debian's file location (I don't know if unique to debian and derivates, that are many distro, in any case, and with ubuntu one of the most used).
Thanks a lot

This is a bug in the debian kernel.  We don't provide or use genksyms.  The kernel Makefile (I believe) is what calls this.  Please report upstream to debian maintainers.  Closing.
