Description Doug Chapman 2007-12-18 15:58:11 UTC

Description of problem:
Previous versions (such as elfutils-0.125 in RHEL5) of elfutils used off_t in
libelf.h.  At some point after this was changed to off64_t.  From digging
through the header files it appears that off64_t is only used on systems that
can have either 32 or 64 bit variants such as x86.  On ia64 only off_t is defined.

This causes code that includes libelf.h to fail to build.

I wasn't able to find anything in the changelog explaining why the change from
off_t to off64_t was made.  Not sure if the right fix is to go back to off_t or
perhaps to do some #ifdef ia64 magic.

I will be happy to try out any ideas if you do not have easy access to an ia64
system.

Version-Release number of selected component (if applicable):
elfutils-0.131-1.fc9

How reproducible:
100%

Steps to Reproduce:
1. build and install latest elfutils on ia64
2. try building kexec-tools rpm
3.
  
Actual results:
/usr/include/libelf.h:98: error: expected specifier-qualifier-list before 'off64_t'
/usr/include/libelf.h:160: error: expected specifier-qualifier-list before 'off64_t'
/usr/include/libelf.h:201: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'elf_update'
/usr/include/libelf.h:207: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'elf_getbase'
/usr/include/libelf.h:305: error: expected declaration specifiers or '...'
before 'off64_t'
/usr/include/libelf.h:317: error: expected '=', ',', ';', 'asm' or
'__attribute__' before 'elf_getaroff'


Expected results:


Additional info:

Comment 1 Doug Chapman 2007-12-19 02:32:14 UTC

The ltrace package fails to build due to this as well.

Comment 2 Roland McGrath 2007-12-19 03:10:14 UTC

Use -D_FILE_OFFSET_BITS=64 (or autoconf equivalent) to work around, and also to
avoid the bugs with old libelf versions on 32-bit machines.
