HP in their infinite stupidity choose not to use standard ELF dynamic
|
|
|
|
linker interfaces. They also choose not to make their ELF dymamic
|
|
|
|
linker interfaces compatible with the SOM dynamic linker. The
|
|
|
|
net result is we can not use either of the existing somsolib.c or
|
|
|
|
solib.c. What a crock.
|
|
|
|
|
|
|
|
Even more disgusting. This file depends on functions provided only
|
|
|
|
in certain PA64 libraries. Thus this file is supposed to only be
|
|
|
|
used native. When will HP ever learn that they need to provide the
|
|
|
|
same functionality in all their libraries! */

"chatr +dbg enable". Not setting DT_HP_DEBUG_PRIVATE allows debugging
