This create quite a unpleasant situation in OE when 12security flags are enabled and gold or not-gold options are used 13it errors out but errors are not same. 14 15Anyway, with this patch we filter pie options from ARCH_FLAGS 16ouright and take control of generating PIC objects 17 18Helps with errors like 19 20| /mnt/oe/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/x86_64-oe-linux/gcc/x86_64-oe-linux/5.3.0/ld: pseudo_client.o: relocation R_X86_64_PC32 against symbol `pseudo_util_debug_flags' can not be used when making a shared object; recompile with -fPIC 21| /mnt/oe/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/x86_64-oe-linux/gcc/x86_64-oe-linux/5.3.0/ld: final link failed: Bad value 22| collect2: error: ld returned 1 exit status 23| make: *** [lib/pseudo/lib64/libpseudo.so] Error 1 24 25Signed-off-by: Khem Raj <raj.khem@gmail.com> 26--- 27Upstream-Status: Submitted 28 29 configure | 2 ++ 30 1 file changed, 2 insertions(+) 31 32diff --git a/configure b/configure 33index e5ef9ce..83b0890 100755 34--- a/configure 35+++ b/configure 36@@ -339,3 +339,5 @@ sed -e ' 37 s,@ARCH@,'"$opt_arch"',g 38 s,@BITS@,'"$opt_bits"',g 39 ' < Makefile.in > Makefile 40+ 41+sed -i -e 's/\-[f]*pie//g' Makefile 42-- 431.8.3.1 44 45
