# Inconsistency detected by ld.so: dl-close.c: 719: _dl_close: Assertion `map->l_init_called' failed!
|

#
|

# Glibc 2.8 introduced the HP_TIMING element to the rtld_global_ro struct # definition.
|
||||
# If the base is built without power4 the loader won't have this element in
|
||||
# the struct whereas the power4/5/6/... libc will, so there will be a disconnect
|
||||
# between the size of the rtld_global_ro struct between the two and dl_close
|
||||
# ends up getting called incorrectly when it's actually attempting to call a
|
||||
# resolver function. This is because the GLRO() macro simply attempts to
|
||||
# compute an offset and gets the wrong one.
|
||||
# Building the base glibc with --with-cpu=power4 solves this problem.
|
||||
# But: ppc32 can not default to -mcpu=power4 because it would emit instructions
|
||||
# which are not available on G3, G4 etc.
|
||||
#
|
||||
# We simply remove the power4 files, and build the base glibc for a generic powerpc cpu
|
||||
# Additional cputuned libs can now be used on powerpc32
