There is a bug in libtool 1.4.2 when using -prefer-non-pic on hppa: libtool does not pass the -fPIC flag, and then the linker complains about that. Alexandre Oliva confirmed to me that this counts as a bug, as -prefer-non-pic should be ignored (i.e. we should still pass the -fPIC flag) if the target architecture requires -fPIC. For an example of a build failing because of that bug, see http://buildd.debian.org/fetch.php?&pkg=mpeg2dec&ver=0.2.1-2&arch=hppa&stamp=1031760849&file=log&as=raw Alexandre's proposed fix was to try removing the 'hppa* | ' from the line just before 'lt_cv_deplibs_check_method=pass_all ;;' ; I have not been able to test this yet as I dont have easy access to an hppa system. It is possible to work around this by making the configure script test for libtool bugs like in the example below, however I guess you'll all agree this is really ugly: dnl AC_LIBTOOL_NON_PIC ([ACTION-IF-WORKS], [ACTION-IF-FAILS]) dnl check for nonbuggy libtool -prefer-non-pic AC_DEFUN([AC_LIBTOOL_NON_PIC], [AC_MSG_CHECKING([if libtool supports -prefer-non-pic flag]) mkdir ac_test_libtool; cd ac_test_libtool; ac_cv_libtool_non_pic=no echo "int g (int i); int f (int i) {return g(i);}" >f.c echo "int g (int i) {return i;}" >g.c ../libtool --mode=compile $CC $CFLAGS -prefer-non-pic \ -c f.c >/dev/null 2>&1 && \ ../libtool --mode=compile $CC $CFLAGS -prefer-non-pic \ -c g.c >/dev/null 2>&1 && \ ../libtool --mode=link $CC $CFLAGS -prefer-non-pic -o libfoo.la \ f.lo g.lo >/dev/null 2>&1 && \ ac_cv_libtool_non_pic=yes cd ..; rm -fr ac_test_libtool; AC_MSG_RESULT([$ac_cv_libtool_non_pic]) if test x"$ac_cv_libtool_non_pic" = x"yes"; then ifelse([$1],[],[:],[$1]) else ifelse([$2],[],[:],[$2]) fi]) Hope this helps, -- Michel "Walken" LESPINASSE Is this the best that god can do ? Then I'm not impressed. _______________________________________________ Libtool mailing list [EMAIL PROTECTED] http://mail.gnu.org/mailman/listinfo/libtool
