clone 592892 -1 reassign -1 autoconf retitle -1 AS_VAR_GET regression tags -1 + upstream thanks
[ http://bugs.debian.org/592892 ] If I got above right, then I'm cloning this bug for Autoconf and marking it as upstream bug; adding bug-autoconf in Cc:. * Sebastian Andrzej Siewior wrote on Wed, Aug 18, 2010 at 04:53:44PM CEST: > config/f77_get_alignment.m4. > The value should be set in third last line > > | $2=AS_VAR_GET([type_var]) > > It was transformed earlier into > | ofc_type_alignment=$ompi_cv_f77_alignment_LOGICALp1 > but become something totally differnt, > > |ofc_type_alignment=`eval 'as_val=${'type_var'};$as_echo "$as_val"'` > After carefully replacing it with AS_VAR_COPY we get > | eval ofc_type_alignment=\$$as_type_var > > which does the job for now. Puh. Now out quick! Well, AS_VAR_GET is (intentionally) undocumented, so your use of AS_VAR_COPY is the right thing to do (which is why I'll leave the original bug for openmpi). Still, this is a regression in upstream Autoconf that I think should be fixed. The issue is that '*' needs to be translated to 'p' here and the string treated as literal here: cat >configure.ac <<\EOF AC_DEFUN([OMPI_F77_GET_ALIGNMENT],[ AS_VAR_PUSHDEF([type_var], [ompi_cv_f77_alignment_$1]) $2=AS_VAR_GET([type_var]) AS_VAR_POPDEF([type_var])dnl ]) AC_INIT OMPI_F77_GET_ALIGNMENT([LOGICAL*1], [result]) EOF autoconf tail configure should contain a line like: result=$ompi_cv_f77_alignment_LOGICALp1 but instead has something like: as_type_var=`$as_echo "ompi_cv_f77_alignment_LOGICAL*1" | $as_tr_sh` result=`eval 'as_val=${'type_var'};$as_echo "$as_val"'` Thanks, Ralf -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
