Problem with __GI_errno_location and _h__errno_location alias names

[stl]

Thanks for your answers!

I mean a new processor.

My linux port is not completed yet. I am at the stage of romfs mounting, however
I can't do anything more before have build a whole linux system
(kernel, filesystem, user apps, ...)
It is for that reason that I have built my cross-compiler linked against uClibc.
I am "testing" on an old uClinux port, but the Linux version I am
porting is a recent one.

I precise that the executable is converted to FLAT with elf2flt,
because uClinux only run FLAT binaries.
When the executable is handled by elf2flt, the relocations for these
symbols are discarded because of
*UND* section type. When the uclinux flat loader (binfmt_flat.c) load
the executable before running it,
the relocation are computed, except for these symbols. This leaves
instructions in an unexecutable way..
Unfortunately, I haven't any other way to test it at the moment.

Ok. How could I configure to avoid __GI_ aliases?
I have already disable shared support:
ARCH_HAS_NO_SHARED=y
ARCH_HAS_NO_LDSO=y


> so the symbols are weak.  It looks like your libc does not define these symbols?
Yes, as I said, it seems that alias symbols are defined
(__GI_errno_location..) while
uClibc_main() expects non-aliased symbols (__errno_location..)


Here is a "objdump -t __errno_location.o"  :

SYMBOL TABLE:
00000000 l    df *ABS*  00000000 __errno_location.c
00000000 l    d  .text  00000000 .text

00000000  w    F .text.__GI___errno_location    0000000a .hidden
__GI___errno_location
00000000         *UND*  00000000 errno
00000000  w    F .text.__GI___errno_location    0000000a __errno_location

Aliased symbols have .hidden attribute.
Could this be a source of my problem?
