Warning build bfd library wiht gcc 4.6.0+fix

2010-05-10 Thread Duncan Simpson 

At least with my configuration gcc 4.6.0 complains about the initialisation
but non-use of hasdebug in coff_write_object_contents (defined in
bfd/coffcode.h). Since -Werror is in effect this stops the build.

The attached oatch fixes this problem by adding hasdebug=hasdebug; if the
only use of hasdebug fails to appear due to the preprocessor switches in
effect.

IMHO a function of this size needs a very good excuse to hide in a *.h file
instead of a *.c file but that might just be my coding style.

[Bug ld/11583] New: ld aborts in elf_link_output_extsym when given EXTERN() symbol in script.

2010-05-10 Thread cinarus at yahoo dot com 
Hello all,

I was trying to define aliases for some functions in an ld script and ld aborts
in the above function. The command line and output is:

$ ld -o dparse dparse_objs.lds -lc

/usr/lib/libc.so:6: unresolvable symbol `puts' referenced in expression
/usr/lib/libc.so:6: unresolvable symbol `puts' referenced in expression
ld: warning: cannot find entry symbol _start; defaulting to 0804817c
/home/sukru/dparse/src/../obj/_func_main_1.o: In function `_llf_func_main_1':
_func_main_1.c:(.text+0x9d): undefined reference to `_xlfputs'
ld: BFD (GNU Binutils for Ubuntu) 2.18.93.20081009 internal error, aborting at
../../bfd/elflink.c line 8573 in elf_link_output_extsym

ld: Please report this bug.

The version of ld is:

$ ld -v
GNU ld (GNU Binutils for Ubuntu) 2.18.93.20081009

My host:

$ uname -a
Linux sukru-laptop 2.6.27-17-generic #1 SMP Fri Mar 12 03:09:00 UTC 2010 i686
GNU/Linux

I'm running Ubuntu 8.10. 

Here is the contents of the linker script:

EXTERN(_llf_func_main_1);
EXTERN(puts);

_func_main_1 = _llf_func_main_1;
_xlfputs = puts;
cx_main = _llf_func_main_1;

INPUT(_func_main_1.o);

This only occurs if I link with the shared library libc.so. It doesn't happen
when I link with the static library.

In the script, _llf_func_main_1  is defined in the _func_main_1.o file.

I have tried putting
  INPUT(-lc);
before the EXTERN commands to no avail. 

I also tried to do the same thing using command line options -u and --defsym,
but the same thing happens.

[Bug ld/11584] New: ld gives internal error

2010-05-10 Thread denis dot dzyubenko at nokia dot com 
Got an internal error when linking Qt in ubuntu 10.04:


/usr/bin/ld: BFD (GNU Binutils for Ubuntu) 2.20.1-system.20100303 internal 
error, aborting at 
../../bfd/merge.c line 876 in _bfd_merged_section_offset


That happened just once, I cannot reproduce it anymore so don't have any 
additional details. Hope that 
helps.

Applied.
