From 65498f289bded83afb809b24d850647e7c91cd58 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Sun, 31 Jan 2016 00:40:33 -0500 Subject: don't suppress shared libc when linker lacks -Bsymbolic-functions previous work overhauling the dynamic linker made it so that linking libc with -Bsymbolic-functions was no longer mandatory, but the configure logic that forced --disable-shared when ld failed to accept the option was left in place. this commit removes the hard-coded -Bsymbolic-functions from the Makefile and changes the configure test to one that simply adds it to the auto-detected LDFLAGS on success. --- configure | 13 ++++--------- 1 file changed, 4 insertions(+), 9 deletions(-) (limited to 'configure') diff --git a/configure b/configure index a296f8ab..58f496e0 100755 --- a/configure +++ b/configure @@ -565,15 +565,10 @@ tryldflag LDFLAGS_AUTO -Wl,--no-undefined # versions built without shared library support and pcc are broken. tryldflag LDFLAGS_AUTO -Wl,--exclude-libs=ALL -test "$shared" = "no" || { -# Disable dynamic linking if ld is broken and can't do -Bsymbolic-functions -LDFLAGS_DUMMY= -tryldflag LDFLAGS_DUMMY -Wl,-Bsymbolic-functions || { -test "$shared" = "yes" && fail "$0: error: linker cannot build shared library" -printf "warning: disabling dynamic linking support\n" -shared=no -} -} +# Linking with -Bsymbolic-functions is no longer mandatory for +# the dynamic linker to work, but enable it if it works as +# a linking optimization. +tryldflag LDFLAGS_AUTO -Wl,-Bsymbolic-functions # Find compiler runtime library test -z "$LIBCC" && tryldflag LIBCC -lgcc && tryldflag LIBCC -lgcc_eh -- cgit v1.2.1
