Hello everyone,

  I haven't seen an answer for this mail. Would be possible to do such
modifications I commented to the libunwind source code repository?

Thank you!

Hello,

I was compiling libunwind 1.0.1 in a linux/ia64 machine when I found the
following error:

gcc -DHAVE_CONFIG_H -I. -I../include  -I../include
- -I../include/tdep-ia64 -I. -D_GNU_SOURCE -DNDEBUG  -g -O2 -fexceptions
- -Wall -Wsign-compare -MT ptrace/_UPT_find_proc_info.o -MD -MP -MF
$depbase.Tpo -c -o ptrace/_UPT_find_proc_info.o
ptrace/_UPT_find_proc_info.c &&\
mv -f $depbase.Tpo $depbase.Po
ptrace/_UPT_find_proc_info.c:102: error: conflicting types for
‘_UPTi_find_unwind_table’
ptrace/_UPT_internal.h:72: error: previous declaration of
‘_UPTi_find_unwind_table’ was here
make[2]: *** [ptrace/_UPT_find_proc_info.o] Error 1

Looking at _UPT_internal.h (line 72), I guess that the returning type is
not as defined in _UPT_find_proc_info.c (line 102). I'd bet on the type
on the .c file, so I changed the header file and when I reran gmake I
encountered the next error

gcc -DHAVE_CONFIG_H -I. -I../include  -I../include
- -I../include/tdep-ia64 -I. -D_GNU_SOURCE -DNDEBUG  -g -O2 -fexceptions
- -Wall -Wsign-compare -MT ptrace/_UPT_get_dyn_info_list_addr.o -MD -MP
- -MF $depbase.Tpo -c -o ptrace/_UPT_get_dyn_info_list_addr.o
ptrace/_UPT_get_dyn_info_list_addr.c &&\
mv -f $depbase.Tpo $depbase.Po
ptrace/_UPT_get_dyn_info_list_addr.c: In function ‘get_list_addr’:
ptrace/_UPT_get_dyn_info_list_addr.c:65: error: too few arguments to
function ‘_UPTi_find_unwind_table’
gmake[2]: *** [ptrace/_UPT_get_dyn_info_list_addr.o] Error 1

Here, there's a missing argument (IP, Instruction Pointer?). After
looking at the code, I found that IP is not used in IA64, so I passed
(unw_word_t) 0

Has anyone a IA64 machine to test these two changes? Are these
modifications safe?

Regards
