It is interesting that Automake decided to do this:
LINK = $(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) \
$(LIBTOOLFLAGS) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) \
$(AM_LDFLAGS) $(LDFLAGS) -o $@
On one hand I can see that a project needs to take care to ensure that
components it builds are used in the link. On the other hand, I can
see that the user needs a last resort way to influence the library
search path. This implies that a package developer should take great
care to make sure that the content of AM_LDFLAGS will satisfy both
objectives.
This is an autoconf/automake/package issue rather than a libtool
issue.

I stand corrected. I was blaming the wrong package. Sorry about
that. GMP is one of the few packages which may configure itself (by
default) for a different architecture than the default architecture of
the compiler or the architecture that the user requests via CFLAGS.
It makes this decision based on which architecture offers the best
performance rather than what the user needs.

Perhaps, but then, I think that if the user has a good reason to do this, then it should be able to override the settings done at configure time. So, --with-gmp=3DDIR should modify LDFLAGS, not AM_LDFLAGS, because as $(AM_LDFLAGS) appears before $(LDFLAGS), there would be no way to override a -L flag set in AM_LDFLAGS by just modifying LDFLAGS. Note: Mutt also modifies CPPFLAGS / LDFLAGS, not the AM_* versions. > LDFLAGS should be set including the user-provided setting > during the entire configure run so test results should be valid.

The main difference IMHO, is that MPFR will try to get the compiler and flags chosen by GMP, but this is necessary in general (we have much fewer bug reports since we do this), though quite awkward. And if GMP does something in the user's back, MPFR shouldn't be blame for trying to fix things. --=20 Vincent Lef=E8vre <vincent@HIDDEN> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Ar=E9naire project (LIP, ENS-Lyon)

Perhaps, but then, I think that if the user has a good reason to do this, then it should be able to override the settings done at configure time. So, --with-gmp=3DDIR should modify LDFLAGS, not AM_LDFLAGS, because as $(AM_LDFLAGS) appears before $(LDFLAGS), there would be no way to override a -L flag set in AM_LDFLAGS by just modifying LDFLAGS. Note: Mutt also modifies CPPFLAGS / LDFLAGS, not the AM_* versions. > LDFLAGS should be set including the user-provided setting > during the entire configure run so test results should be valid. This is how this works with MPFR. > I know that MPFR configure does work differently than almost any > other software package. I don't know what you mean here. The main difference IMHO, is that MPFR will try to get the compiler and flags chosen by GMP, but this is necessary in general (we have much fewer bug reports since we do this), though quite awkward. And if GMP does something in the user's back, MPFR shouldn't be blame for trying to fix things. --=20 Vincent Lef=E8vre <vincent@HIDDEN> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Ar=E9naire project (LIP, ENS-Lyon)

This can cause problems when an older version of the > library is installed in $prefix. Or perhaps the -L shouldn't be added at all automatically, but should be specified in the Makefile.am file? For instance, should -L$(top_builddir)/src/.libs be added to AM_LDFLAGS in tests/Makefile.am? Since $(AM_LDFLAGS) appears before $(LDFLAGS) in the LINK command, this should solve the problem. This -L flag would then be used also on systems that don't need it, but I don't think this is a problem. --=20 Vincent Lef=E8vre <vincent@HIDDEN> - Web: <http://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <http://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Ar=E9naire project (LIP, ENS-Lyon)

When it can libtool will add the path to the .so instead of -L -l for libraries in the build dir. On many systems this works, but HP-UX is one of those systems where it does not, so -L -l are used instead. This can cause problems when an older version of the library is installed in $prefix. Sorry that I can't help more. Thanks, Peter

If the user modifies the environment at make time, the configure tests no longer make sense (e.g. modifying LDFLAGS at make time can select a different GMP version). So, if the user does this, it is up to him to make sure that the changes are equivalent to what was set at configure time. > Something like the attached patch should work for mpfr. There are several problems with it. First, I assume that LOADLIBES should contain $(AM_CPPFLAGS) too. But the main problem is the inconsistent flags order: in the compile command, $(AM_CPPFLAGS) appears before $(CPPFLAGS), while in the link command, $(GMP_LIBS) appears after $(LDFLAGS).

Hi Vincent,
Well, if this is a bug at all, it is an automake/autoconf one, libtool
does not set the order of flags in Makefile.in, but I don't believe that
it is a bug.
LDFLAGS, CFLAGS, etc are for the user to set. It should be possible for
the user to build a package doing ./configure ..options..; make
LDFLAGS=-fancyflag CPPFLAGS=-I/want/coffee;
http://www.gnu.org/prep/standards/standards.html#Command-Variables
The usual way to get specific flags set to allow this is to save
LDFLAGS, CPPFLAGS etc. before doing an autoconf test, do the test, then
restore the original flags.
Something like the attached patch should work for mpfr.
Peter

Hi Vincent, Unfortunately this is a fairly common problem. If the flags were added by the user, they could set LIBS=-L/opt/gnu/lib instead on some platfroms, but that won't work on HP-UX either because its linker is rather strict that -L flags for paths that contain the library be ordered before the -l flag for that library. Anyway, the problem can be avoided by not putting the -L and -l flags for gmp in LDFLAGS and LIBS, instead put both in e.g. GMP_LIBS, (GMP_LIBS="-L/opt/gnu/lib -lgmp"), then add $(GMP_LIBS) to LDADD.

With libtool 2.4 and automake 1.11.1, we have the following problem
for MPFR 3.1.0. We have received a bug report saying that when the
tests are run on a HP-UX machine, the following command is run:
libtool: link: gcc -O2 -s -o tversion tversion.o -L/opt/gnu/lib ./.libs/libfrtests.a -lm -L../src/.libs -lmpfr -lgmp -Wl,+b -Wl,/xxx/gnu/mpfr-3.1.0/objdir/src/.libs:/opt/gnu/lib
The problem is that -L../src/.libs comes after -L/opt/gnu/lib, so that
linking is done against the MPFR version installed in /opt/gnu/lib
instead of the one from ../src/.libs, which has just been compiled.
-L/opt/gnu/lib comes from LDFLAGS (set up by the configure script);
it is needed to find some other library (GMP). -L../src/.libs is
added to find the MPFR library to be tested (it is necessary under
HP-UX). It seems to be added to $LIBS, where in tests/Makefile.in,
one gets:
LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) \
--mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) \
$(LDFLAGS) -o $@
tversion$(EXEEXT): $(tversion_OBJECTS) $(tversion_DEPENDENCIES)
@rm -f tversion$(EXEEXT)
$(LINK) $(tversion_OBJECTS) $(tversion_LDADD) $(LIBS)
Note: the problem cannot be reproduced under Linux, as
../src/.libs/libmpfr.so is used instead of -L... -lmpfr.
