Subject: binutils 2.5.2.6 is released
Newsgroups: comp.os.linux.announce
Keywords: binutils
Organization: ?
Approved: linux-announce@tc.cornell.edu (Lars Wirzenius)
Followup-to: comp.os.linux.misc
This is the binary release of binutils 2.5.2.6. It fixes a few bugs:
1. When using gcc -g without -static in the final linking in the
a.out format, the linker will inform you which shared library
is missing and no executables will be outputted. You should
use -g and -static or remove -g if that happens.
2. Sometimes ld will put an extra page between text and data if
text ends on the page boundary. It is fixed.
3. as may mis-assemble the PIC code.
4. From Eric: I was trying to link a shared library, and I was
explicitly linking against a different shared library. I had a
symbol test2 (function, actually), which was referenced in
lib2.o and defined in lib1.so. When we entered the function
elf_i386_relocate_section, we would discover the relocation, and
see that it was a defined symbol. We attempt to look up the
relocation value for this relocation, and we segfault because the
input section came from the shared library, and thus the input
section had no output section defined. The point was that this
value for relocation that we were trying to calculate was irrelevant
- since this was a PLT32 relocation, a PLT slot exists for this
symbol, and we calculate a new value for the relocation based upon
the plt_offset field. Thus the enclosed fix works because we know
that we will choose a new value for relocation later on.
5. Put the .ctors/.dtors in the data segment since they are writable.
6. Fix the problem whereby applications can be linked and have
unresolved externals - if there were unresolved externals in shared
libraries that we were not resolving, then there are no assocuated
relocations, and the user gets no messages. The patch watches for
this specific case and reports an undefined symbol message if this
happens.
7. Take out Lynx support in the ELF linker
8. Fix a bug in the ELF linker.
9. Add the man pages.
The primary ftp sites for the compiler/C library are tsx-11.mit.edu
under pub/linux/packages/GCC and sunsite.unc.edu under pub/Linux/GCC.
You need libc 4.6.27 or above to run this package. ld.so 1.5.2 or
above is REQUIRED.
To install this package, please follow the procedure very closely.
Please backup/save all the files you are instructed to delete and you
should do
tar tvvfz binutils-2.5.2.6.bin.tar.gz
tar tvvfz binutils-2.5.2.6.man.tar.gz
to see what is in there. The pacth from 2.5.2 to 2.5.2.6, is enclosed
here.
To install, PLEASE DO
1. su root
2. cd /usr/bin
3. rm -f as ar gprof ranlib size objdump objcopy nm strip strings gasp c++filt
4. cd /
5. tar xfz binutils-2.5.2.6.bin.tar.gz
6. tar xfz binutils-2.5.2.6.man.tar.gz
Now you have the new gas/binutils under /usr/bin.
Thanks.

----
This patch contains some necessary bug fixes for binutils 2.5.2 to
support ELF. It is called 2.5.2.6 by me. The fixes may not be the same
as the ones in the next public release of binutils.
