Description of problem: On sh architecture, gcc(gfortran) passes "-little" option to gas when compiling. This causes the failure of configure script which checking gfortran. Here is the example when running configure script HDF4.2r2, checking how to get verbose linking output from gfortran... -v checking for Fortran 77 libraries of gfortran... -little -L/usr/lib/gcc/sh4-redhat-linux/4.1.2 -L/usr/lib/gcc/sh4-redhat-linux/4.1.2/../../.. -lgfortranbegin -lgfortran -lm checking for dummy main to link with Fortran 77 libraries... unknown configure: error: linking to Fortran libraries from C fails See `config.log' for more details. and config.log . configure:4729: checking for Fortran 77 libraries of gfortran configure:4752: gfortran -o conftest -g -O2 -v conftest.f Using built-in specs.

The current gcc passes "-little" to gas even in gcc trank for compatibility. Then we have to special treatment for this option. Here is a proposed patch not to recognize "-little" as library option but special option to be ignored. We also need patches which are already generated configure script, but I'll file as Bugs. --- lib/autoconf/fortran.m4.org 2008-07-28 22:26:19.000000000 +0900 +++ lib/autoconf/fortran.m4 2008-07-28 22:26:37.000000000 +0900 @@ -666,7 +666,7 @@ [_AC_LINKER_OPTION([$ac_arg], ac_cv_[]_AC_LANG_ABBREV[]_libs)]) ;; # Ignore these flags. - -lang* | -lcrt*.o | -lc | -lgcc* | -lSystem | -libmil | -LANG:=* | -LIST:* | -LNO:*) + -little | -lang* | -lcrt*.o | -lc | -lgcc* | -lSystem | -libmil | -LANG:=* | -LIST:* | -LNO:*) ;; -lkernel32) test x"$CYGWIN" != xyes && ac_cv_[]_AC_LANG_ABBREV[]_libs="$ac_cv_[]_AC_LANG_ABBREV[]_libs $ac_arg" Version-Release number of selected component (if applicable): autoconf-2.61-10
I reported to upstream and revised patch was merged. http://lists.gnu.org/archive/html/bug-autoconf/2008-10/msg00039.html http://lists.gnu.org/archive/html/bug-autoconf/2008-10/msg00040.html
Thanks for passing that upstream to get it fixed CHIKAMA.
