From: Perl 5 Porters Date: Thu, 10 Oct 1996 02:09:48 +0000 (+0000) Subject: perl 5.003_07: Configure X-Git-Url: http://git.shadowcat.co.uk/gitweb/gitweb.cgi?a=commitdiff_plain;h=a4f3eea9be6bcf3c1a2f99ac49d0585bf5fe8789;p=p5sagit%2Fp5-mst-13.2.git perl 5.003_07: Configure Detect GNU libc (thanks, Skimo!) and avoid nm if we have GNU libc. Since the GNU libc test requires compiling and linking a test program, the dependencies have been altered and lots of pieces of Configure have moved around unchanged. The patch is big but the effect is little. Allow for both and in fd_set tests. Systems which don't allow both (e.g. SCO) have to turn off one or the other in the hints file for now. --- diff --git a/Configure b/Configure index 5859e51..36f612c 100755 --- a/Configure +++ b/Configure @@ -20,7 +20,7 @@ # $Id: Head.U,v 3.0.1.8 1995/07/25 13:40:02 ram Exp $ # -# Generated on Fri Oct 4 15:07:00 EDT 1996 [metaconfig 3.0 PL60] +# Generated on Thu Oct 10 15:08:34 EDT 1996 [metaconfig 3.0 PL60] cat >/tmp/c1$$ </dev/null` - if $test $dflt -gt 20; then - dflt=y - else - dflt=n - fi - ;; -*) - case "$usenm" in - true) dflt=y;; - *) dflt=n;; - esac - ;; -esac -$cat < /dev/null 2>&1; then - nm_so_opt='--dynamic' - fi - ;; - esac - ;; -esac - -case "$runnm" in -true) -: get list of predefined functions in a handy place -echo " " -case "$libc" in -'') libc=unknown - case "$libs" in - *-lc_s*) libc=`./loc libc_s.a $libc $libpth` - esac - ;; -esac -libnames=''; -case "$libs" in -'') ;; -*) for thislib in $libs; do - case "$thislib" in - -lc|-lc_s) - : Handle C library specially below. - ;; - -l*) - thislib=`echo $thislib | $sed -e 's/^-l//'` - if try=`./loc lib$thislib.$so.'*' X $libpth`; $test -f "$try"; then - : - elif try=`./loc lib$thislib.$so X $libpth`; $test -f "$try"; then - : - elif try=`./loc lib$thislib.a X $libpth`; $test -f "$try"; then - : - elif try=`./loc lib$thislib X $libpth`; $test -f "$try"; then - : - elif try=`./loc $thislib X $libpth`; $test -f "$try"; then - : - elif try=`./loc Slib$thislib.a X $xlibpth`; $test -f "$try"; then - : - else - try='' - fi - libnames="$libnames $try" - ;; - *) libnames="$libnames $thislib" ;; - esac - done - ;; -esac -xxx=normal -case "$libc" in -unknown) - set /lib/libc.$so - for xxx in $libpth; do - $test -r $1 || set $xxx/libc.$so - : The messy sed command sorts on library version numbers. - $test -r $1 || \ - set `echo blurfl; echo $xxx/libc.$so.[0-9]* | \ - tr ' ' '\012' | egrep -v '\.[A-Za-z]*$' | $sed -e ' - h - s/[0-9][0-9]*/0000&/g - s/0*\([0-9][0-9][0-9][0-9][0-9]\)/\1/g - G - s/\n/ /' | \ - sort | $sed -e 's/^.* //'` - eval set \$$# - done - $test -r $1 || set /usr/ccs/lib/libc.$so - $test -r $1 || set /lib/libsys_s.a - ;; -*) - set blurfl - ;; -esac -if $test -r "$1"; then - echo "Your (shared) C library seems to be in $1." - libc="$1" -elif $test -r /lib/libc && $test -r /lib/clib; then - echo "Your C library seems to be in both /lib/clib and /lib/libc." - xxx=apollo - libc='/lib/clib /lib/libc' - if $test -r /lib/syslib; then - echo "(Your math library is in /lib/syslib.)" - libc="$libc /lib/syslib" - fi -elif $test -r "$libc" || (test -h "$libc") >/dev/null 2>&1; then - echo "Your C library seems to be in $libc, as you said before." -elif $test -r $incpath/usr/lib/libc.a; then - libc=$incpath/usr/lib/libc.a; - echo "Your C library seems to be in $libc.
