THis breaks static building of target alpha:

I think it is this part of the patch: diff --git a/ldso/include/dl-defs.h b/ldso/include/dl-defs.h index daa6685cb..e404f17ec 100644 --- a/ldso/include/dl-defs.h +++ b/ldso/include/dl-defs.h @@ -72,10 +72,8 @@ typedef struct { #endif #ifdef _LIBC -#ifndef __ARCH_HAS_NO_SHARED__ /* arch specific defines */ #include <dl-sysdep.h> -#endif #ifdef __TARGET_c6x__ #include <dl-sysdep.h> #endif
Any idea?
Yes, that is definitely the cause. I mis-understood the implications of removing that "#ifndef __ARCH_HAS_NO_SHARED__" conditional.
I am testing a different change here that I think might do ther job better:
--- a/ldso/include/dl-defs.h +++ b/ldso/include/dl-defs.h @@ -72,7 +72,7 @@ #endif
#ifdef _LIBC -#ifndef __ARCH_HAS_NO_SHARED__ +#ifndef __ARCH_HAS_NO_LDSO__ /* arch specific defines */ #include <dl-sysdep.h> #endif
That fixes the alpha problem, thanks.
But now it fails for ARM FDPIC target.

Ok, this is strange. I don't see this with my ARM fdpic testing.
Can you send me your uClibc-ng .config file?
reloc_static_pie.os is only compiled if STATIC_PIE is enabled (as per libc/misc/internals/Makefile.in) and STATIC_PIE can only be set if !UCLIBC_FORMAT_FDPIC_ELF is true (as per extra/Configs/Config.in). Unless I am missing something?
Regards Greg
