Hi Monty,

Files listed in BUILT_SOURCES are not taken into account wrt
distribution. The distribution list is built from other primary-like
constructs, such as *_SOURCES. The example in the autoconf manual shows
how you would do what you want:

nodist_foo_SOURCES = bindir.h
BUILT_SOURCES = bindir.h

In this example, BUILT_SOURCES is used only to get bindir.h built up
front. The actual SOURCES variable used to list its use by a particular
product carries the nodist prefix, which keeps it from being distributed.
I tried removing it from BUILT_SOURCES and adding in a rule that looks like:

You can't (or rather shouldn't) fully expand these variables at
configure time because they may be modified at make time by the user on
the make command line (e.g., make prefix=xxx). There are two
widely-practiced options:

1. Replace such variables on the compiler command line for all or some

mylib_la_CPPFLAGS =\
 -DSYSLOGDIR=\"$(syslogdir)\" ...

This works well for situations where you only have a few variables to

2. Add some custom rules to your scripts that build your
source files using variable replacement techniques like those used by


edit = sed \
   -e 's|@address@hidden|$(sysconfdir)|g' \
   -e 's|@address@hidden|$(sysrundir)|g' \
   -e 's|@address@hidden|$(syslogdir)|g' \
   -e 's|@address@hidden|$(libexecdir)|g' \
   -e 's|@address@hidden|$(sbindir)|g'\
   -e 's|@address@hidden|$(prefix)|g'

all: myprog.cfg

# Build executable scripts
myprog.cfg : Makefile
        $(edit) '$(srcdir)/address@hidden' > $@

Then just format your input templates just like autoconf input templates
with @variable@ where ever you want variable replacement to occur at
make time.
