The Error:
ar: `u' modifier ignored since `D' is the default (see `U')
The temporary solution:
So I've basically come to the point that to make this work you have to modify two files and change "cru" to "cr" in them :
/usr/share/aclocal/libtool.m4
and
/usr/share/libtool/configure
./autogen.sh and ./configureAdditionally add to make command line::
make ARFLAGS="cr" AR_FLAGS="cr"
====================
This affectively suppresses the warning from appearing, but it's not a clean way to make this work. Could you please assist with this matter thank you. Also I've looked into the libtool repository : git://git.savannah.gnu.org/libtool.git and saw a NEWS file stating:
* New features:
- Libtool script now supports (configure-time and runtime) ARFLAGS
variable, which obsoletes AR_FLAGS. This is due to naming conventions
among other *FLAGS and to be consistent with Automake's ARFLAGS.
- Gnulib testsuite is enabled and run during 'make check'.
** Important incompatible changes:
- Libtool changed ARFLAGS/AR_FLAGS default from 'cru' to 'cr'.
However, it's unclear how the configure-time and runtime ARFLAGS var should be set. Various options have been tried in the configure.ac and Makefile.am files, but nothing worked.
