if test -f ../libquadmath/libquadmath.la; then
LIBQUADLIB=../libquadmath/libquadmath.la
LIBQUADLIB_DEP=../libquadmath/libquadmath.la
LIBQUADINCLUDE='-I$(srcdir)/../libquadmath'
else
LIBQUADLIB=-lquadmath
LIBQUADLIB_DEP=
LIBQUADINCLUDE=
fi
Not sure why do we have this, when test x$libgfor_cv_have_float128 = xyes
then I'd say libquadmath should have been built always.
The dependencies in toplevel:
dependencies = { module=configure-target-libgfortran;
on=all-target-libquadmath; };
and thus
configure-target-libgfortran: maybe-all-target-libquadmath
should take care of it.
Anyway, Thomas, have you ever been able to reproduce it again?

Well, that was proposed by Ralf to allow optionally use a system installed libquadmath instead of the GCC build one. (This requires the patch for PR 46540 which disables the build of libquadmath (--disable-libquadmath) but which still builds gfortran/libgfortran with quadmath support.)

(In reply to comment #1)
The issue seems to be fixed after upgrading to automake 1.11.1
from 1.11, so I am ready to resolve this as invalid.
1.11.1 is the correct version according to
http://gcc.gnu.org/install/prerequisites.html (GCC requires the latest release
in the 1.11 series, which is currently 1.11.1.)
However, two points:
- The build process complains about the automake 1.11, but this warning
scrolls past really fast, and if automake 1.11 really causes issues,
this should be addressed.
No idea about that one. Except: When regenerating a directory to a newer
version, please update all the directories using an older 1.11 to the latest
released version.
- The timestamps on the generated files should be set so that no
unneeded regeneration takes place.
No idea. Except using ./contrib/gcc_update, which touches the and the
configure/*.in files if it thinks that it is needed. (Causing that autoreconf
is not run because the touched configure files is newer than the modified
configure.ac file.)
* * *
Some older comments - written before comment 1 was available.
libgfortran/acinclude.m4 contains:
if test -f ../libquadmath/libquadmath.la; then
[...];
LIBQUADINCLUDE='- I$(srcdir)/../libquadmath'
else
[...]
LIBQUADINCLUDE=
Thus, the .h file can only be found if ../libquadmath/libquadmath.la is found
or when the .h file is for other reasons in the include path.
There might be also a race condition in building libgfortran and libquadmath;
however, I think (TM) that the following line of Makefile.def should take care
of it:
dependencies = { module=configure-target-libgfortran;
on=all-target-libquadmath; };
Given that many have bootstrapped successfully with and without
--enable-maintainer-mode, I assume either a race condition or that there is
something peculiar on the specific system, which triggers this bug.
