Automake - distcheck fails on install-exec-hook

[Asaf Dalet]

Hi all,
I have this Makefile.am:

AUTOMAKE_OPTIONS = subdir-objects
sbin_PROGRAMS = foo
foo_SOURCES = foo.c
install-exec-hook:
    chmod +s $(sbindir)/foo

everything works well except for the target *distcheck* which gives this
error:

> make distcheck
...
...
...
Making install in sub-module

Makefile:645: recipe for target 'install-exec-hook' failed
make[4]: *** [install-exec-hook] Error 1

it looks like the *foo* binary is copied to some temp directory
(/var/folders/pp/jbr_vq091s7gd8x9scrc7drw0000gn/T//am-dc-71151//home/users/a/myproj/_inst/sbin)
and not to where it is looked at in the install-exec-hook target
(/home/users/a/myproj/_inst/sbin)

What am I missing??


Thanks,

Asaf
