Cache consistency checking: ignore cache if environment
|

(CC or PATH) differs.
|
||||
From Mike Haertel
|
||||
|
||||
So we need a general mechanism for storing variables' values in the cache,
|
||||
and checking if they are the same after reading the cache. Then we can add
|
||||
to the list of variables as we come across the need. So far we want
|
||||
LD_LIBRARY_PATH and the internal variables for some of (all?) the args.
|
||||
From: roland@gnu.ai.mit.edu (Roland McGrath)
|
||||
|
||||
Hmm. That list might include LD_LIBRARY_PATH, LD_RUN_PATH (for solaris),
|
||||
and PATH. I can't think of any others so far.
|
||||
From: friedman@splode.com (Noah Friedman)
|
||||
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
So how about an option to configure --reset-cache, that says to ignore all
|
||||
existing cached values for tests that configure runs, and then update the
|
||||
cache normally. This should be utterly trivial to do in AC_CACHE_VAL;
|
||||
check the flag variable and always compute the value if it's set.
|
||||
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
A number of people have tried to fix configuration problems by editing
|
||||
acconfig.h. (Despite comments at the top of the file.) I think they're
|
||||
confused because anything.h looks like a regular source file name.
|
||||
Maybe acconfig.h could be called acconfig.extra or something?

Every user running
|
||||
X11 usually has a directory like *X11* in his PATH variable. By replacing

bin by include, you can find good places to look for the include files

or libraries.

|

|
||||
in order to use the AC_CANONICAL_SYSTEM macro, I have to
|
||||
have install-sh somewhere nearby --- why is this? I have no real
|
||||
reason to distribute install-sh, other than that its absence breaks
|
||||
this code.
|
||||
|
||||
Shouldn't the above loop be looking for config.sub and config.guess?
|
||||
From: jimb@totoro.bio.indiana.edu (Jim Blandy)
|
||||
|
||||
adding AC_CANONICAL_HOST to my configure.in script caused
|
||||
all sorts of odd/unexplained errors. Obviously, I had to go
|
||||
get copies of config.guess, config.sub and install-sh from the
|
||||
autoconf distribution, but the error messages and autoconf docs
|
||||
didn't explain that very well.

From: bostic@bsdi.com (Keith Bostic)

------------------------------------------------------------------------------
|
||||
|
||||
Combine AC_PROG_CC_WORKS with AC_C_CROSS. If the compiler exits with
|
||||
a 0 status and produces a non-empty output file, consider it working.
|
||||
If the output file is runnable, consider it native, also.
|
||||
Perhaps also have AC_PROG_CC_WORKS try to link an invalid program, and
|
||||
die if the compiler seemed to succeed--in which case it's not usable
|
||||
with autoconf scripts.
|
||||
|
||||
------------------------------------------------------------------------------
|
||||
|
||||
When using CONFIG_FILES= and CONFIG_HEADERS= for controlling
|
||||
partial configuration, any AC_LINK_FILES is repeated in each case
|
||||
(that is, usually, once for config.h and once per subdirectory).
|
||||
This is not elegant.
|
||||
|
||||
Maybe Autoconf could use some kind of CONFIG_LINKS=<file-list>,
|
||||
having all such AC_LINK(ed)_FILES by default, but usable by each
|
||||
Makefile.in in rules for updating the particular links they need.

||||
|
||||
From: pinard@iro.umontreal.ca
|

|
||||
------------------------------------------------------------------------------
|
||||
|
||||
Perhaps autoconf could have a single @magic@ frob that gets replaced with
|
||||
assignments for all the *dir variables? There is quite a plethora for each
|
||||
Makefile.in to have foodir = @foodir@.

|

|

In most cases, when autoscan suggests something, using the search
|
||||
or index command into the Info reader for autoconf manual quickly
|
||||
explains me what the test is about. However, for header files
|
||||
and functions, the search might fail, because the test is not of
|
||||
the specific kind. The Autoconf manual should reflect somewhere
|
||||
all header files or functions (non-specific features, generally)
|
||||
triggering autoscan to generate tests, and tell in a few words
|
||||
what is the problem, and the suggested approach for a solution;
|
||||
that is, how one should use the result of testing the feature.

Rick Boykin <rboykin@cscsun3.larc.nasa.gov>
|
||||
|
||||
Under Solaris 2.4, the regular X includes and libs and the Motif
|
||||
includes and libs are in different places. The Emacs configure script
|
||||
actually allows dir1:dir2:dir3 --
|
||||
|
||||
if test "${x_libraries}" != NONE && test -n "${x_libraries}"; then
|
||||
LD_SWITCH_X_SITE=-L`echo ${x_libraries} | sed -e "s/:/ -L/g"`
|
||||
LD_SWITCH_X_SITE_AUX=-R`echo ${x_libraries} | sed -e "s/:/ -R/g"`

fi
|

if test "${x_includes}" != NONE && test -n "${x_includes}"; then

|

|

What messages should be produced by default, if any?
|
||||
|
||||
Probably only the few most important ones, like which configuration
|
||||
name was used, whether X or Xt are in use, etc. The specific
|
||||
decisions, and progress messages, should be recorded on the terminal
|
||||
only if --verbose is used.
|
||||
|
||||
--silent just supresses the "checking for...result"
|
||||
messages, not the "creating FOO" messages.
|
||||
|
||||
I think the default should be to suppress both.
|
||||
From: Richard Stallman <rms@gnu.ai.mit.edu>
|
||||
|
||||
There is no distinction now between
|
||||
important decisions (we have X) vs minor decisions (we have lstat).
|
||||
However, there are probably only a few things you deem important enough to
|
||||
announce and only those few things will need to be changed.
|
||||
Perhaps config.status could be written with comments saying what was
|
||||
decided.

|
||||
|
||||
about the idea of using small configure.in/aclocal.m4 snippets:
|
||||
this is the one idea in metaconfig (the autoconf-like program used by
|
||||
Perl) that I like. metaconfig looks for a "U" directory, and includes
|
||||
each ".U" file into the generated Configure script (according to
|
||||
various complicated rules).

I'd much prefer to see the absolute paths substituted for all the

standard "dir" variables. It would be nice to have variables in

configure that held the absolute paths. And it is nice to be able to
|

substitute them into other files without relying on the destination

file supporting ${...} syntax. (It works in Perl, sh, and make --

Another thing I wish for is a macro which figures out which libraries are
