From a2ef941b2d74bfe47998e5afa29943f2f43642ae Mon Sep 17 00:00:00 2001 From: Xi Ruoyao Date: Mon, 27 Feb 2023 19:08:09 +0800 Subject: LoongArch: Further refine the condition to enable static PIE Before GCC r13-2728, it would produce a normal dynamic-linked executable with -static-pie. I mistakely believed it would produce a static-linked executable, so failed to detect the breakage. Then with Binutils 2.40 and (vanilla) GCC 12, libc_cv_static_pie_on_loongarch is mistakenly enabled and cause a building failure with "undefined reference to _DYNAMIC". Fix the issue by disabling static PIE if -static-pie creates something with a INTERP header. --- sysdeps/loongarch/configure | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'sysdeps/loongarch/configure') diff --git a/sysdeps/loongarch/configure b/sysdeps/loongarch/configure index f6c078c..b3c203b 100644 --- a/sysdeps/loongarch/configure +++ b/sysdeps/loongarch/configure @@ -48,6 +48,12 @@ EOF ac_status=$? $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5 test $ac_status = 0; }; } \ + && ! { ac_try='LC_ALL=C $READELF -Wl conftest1 | grep -q INTERP' + { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$ac_try\""; } >&5 + (eval $ac_try) 2>&5 + ac_status=$? + $as_echo "$as_me:${as_lineno-$LINENO}: \$? = $ac_status" >&5 + test $ac_status = 0; }; } \ && { ac_try='${CC-cc} $CFLAGS $CPPFLAGS $LDFLAGS -shared -fPIC -o conftest2.so conftest2.S' { { eval echo "\"\$as_me\":${as_lineno-$LINENO}: \"$ac_try\""; } >&5 (eval $ac_try) 2>&5 -- cgit v1.1
