Hey guys,
I find myself in need of a ./configure option to set the
cache_effective_user other than 'nobody' on a per-dist basis, leaving
the squid.conf setup as-is.
Can someone please explain to me how the @HTTP_PORT@ etc get
replaced in squid.conf / cf.data.pre
I have tried modifying src/makefile.am and ./configure.in to no
visible effect.
Calling AC_DEFINE (etc) causes the variables to be set for autoconf.
After ./configure runs, you should see them in config.status. eg:
s,@CACHE_HTTP_PORT@,3128,;t t
config.status does the substitutions from Makefile.in to Makefile.
for example:
$ sh config.status
...
config.status: creating src/Makefile
So in src/Makefile.in you have:
DEFAULT_HTTP_PORT = @CACHE_HTTP_PORT@
While in src/Makefile you have:
DEFAULT_HTTP_PORT = 3128
Our src/Makefile (but you must edit src/Makefile.am of course) has
a long-ish sed commands to do very similar substitutions on the
cf.data.pre file:
cf.data: cf.data.pre Makefile
sed "\
[EMAIL PROTECTED]@%$(DEFAULT_HTTP_PORT)%g;\
[EMAIL PROTECTED]@%$(DEFAULT_ICP_PORT)%g;\
...
Thanks Duane,
What you have just written matched perfectly with my earlier reading
straight from the code. So I still can't see whats going wrong here.
So if you want to add your own macro goop you have to (at least):
- modify configure.in (if you want it to be set via ./configure)
yes:::
AC_ARG_WITH(cache-user,
[ --with-cache-user=USER System user account for squid permissions.
default: nobody],
[ if tets -z "$withval"; then
AC_DEFINE(cfg_CACHE_EFFECTIVE_USER, "$withval", [change User for
squid to $withval])
else
AC_DEFINE(cfg_CACHE_EFFECTIVE_USER, "nobody", [default User for squid])
fi
])
AC_SUBST(cfg_CACHE_EFFECTIVE_USER)
- modify src/Makefile.am
yes:::
[EMAIL PROTECTED]@%$(cfg_CACHE_EFFECTIVE_USER)%g;\
- run bootstrap.sh (Makefile.am -> Makefile.in)
yes. it gives me ...
./src/Makefile.in: (looks OK)
cfg_CACHE_EFFECTIVE_USER = @cfg_CACHE_EFFECTIVE_USER@
...
[EMAIL PROTECTED]@%$(cfg_DEFAULT_CACHE_EFFECTIVE_USER)%g;\
./configure: (looks OK)
# Check whether --with-cache-user was given.
if test "${with_cache_user+set}" = set; then
withval=$with_cache_user; if test -z "$withval"; then
cat >>confdefs.h <<\_ACEOF
#define cfg_CACHE_EFFECTIVE_USER "$withval"
_ACEOF
else
cat >>confdefs.h <<\_ACEOF
#define cfg_CACHE_EFFECTIVE_USER "nobody"
_ACEOF
fi
fi
- modify the sed command in the cf.data target of src/Makefile
?? was done in Makefile.am, bootstrap did it for src/Makefile automatically.
- modify cf.data.pre to use the new macro
yes:::
DEFAULT: @DEFAULT_CACHE_EFFECTIVE_USER@
- run ./configure and test it..
yes, gives me ...
./src/Makefile:
cfg_CACHE_EFFECTIVE_USER =
...
[EMAIL PROTECTED]@%$(cfg_CACHE_EFFECTIVE_USER)%g;\
And thats where I see the problem. Running make now will replace with ""
instead of "nobody" (default option wanted for this test)
