Subject: RE: crosstool-0.28-rc36: ld.so.1 undefined reference
To: Dan Kegel <dank@kegel.com>
cc: crossgcc@sources.redhat.com
gcc-3.4.0-glibc-2.2.5 barfs with a few undefined refereces and multiple
definitions. The follwing patch seems to take care of the undefined
reference of __dl_runtime_resolve symbol.
Filename: patches/glibc-2.2.5/glibc-2.2.5-mips-dl-machine-1.60.patch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Retrieved with
wget 'http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/mips/dl-machine.h.diff?r1=1.59&r2=1.60&cvsroot=glibc'
See http://sources.redhat.com/ml/libc-alpha/2002-02/msg00091.html
See also glibc-2.2.5-mips-build-gmon.patch, which takes care of the other part of this for mips.
ChangeLog:
sysdeps/mips/dl-machine.h (elf_machine_matches_host): Use
__attribute_used__.
(__dl_runtime_resolve): Likewise.
Fixes error
