Subject: glade configure.ac patch
Hi Tristan,
I am mailing you directly, because I couldn't find the right mailing
list for glade and you just released a 3.8.1 stable release.
Attached is a patch for configure to use AC_CANONICAL_HOST. (in master
_SYSTEM is already changed to _TARGET, but it also should be _HOST)
For a rationale, please see
http://www.flameeyes.eu/autotools-mythbuster/autoconf/canonical.html

Can you clarify for me what this will change ?

Currently from reading this I think it should probably be _TARGET, not _HOST.

"The system against which the software being built will run on. This
actor only exists, or rather has a meaning, when the software being
built may interact specifically with a system that differs from the
one it's being executed on (our host). This is the case for compilers,
debuggers, profilers and analyzers and other tools in general."

Cheers,
-Tristan

To be fair, _HOST looks like it's right for "just about anything"..
I'm more curious
about what is the justification for this change, why do you for
instance want this change ?

Would changing _TARGET to _HOST mean that you can no longer
cross-compile Glade ?

Changing _TARGET to _HOST would most probably mean being able to
correctly cross compile.

"""To clarify a bit further: target is specific to *compiling* compilers
and related tools that produce system-specific output. For example:
On a GNU/Linux system ($build) I build a compiler that itself will run
on FreeBSD ($host) but create code that can be executed on MinGW
($target)."""

Credit goes to Keith Marshall and Ralf Wildenhues for this
explanation (from the mingw-***@sourceforge.net mailing list).
I've inserted the *compiling* in the first sentence for extra
clearness.

Software not falling in the category of "compilers and related tools"
simply have no business using ($target) and/or it's associated macro's.

mvg,
Dieter

Here's another great explanation, also by Keith Marshall, starting
with the text "Ok, I think some clarification of the meanings of
`build', `host' and `target' would be helpful":
