Lutz,
I think you have found the problem.

Here I try to cast (convert) a thread object into a long integer.
Maybe a (handle to) thread object in HP-UX is represented as a struct,
and the typecast is not possible. Solution: change the typedef in
os0thread.h to:
typedef pthread_t os_thread_id_t
and replace comparisons like thr_id1 == thr_id2 by
pthread_equal(thr_id1, thr_id2)
Well, this needs some work from me, as the source code must be changed
possibly on several lines. Another possibility is that if you from the
header file pthread.h for HP-UX see how to convert a thread handle to
a (unique) unsigned long integer, you could try that fix on line 29.
>os0thread.c: In function `os_thread_create':
>os0thread.c:69: warning: dereferencing `void *' pointer
>os0thread.c:69: invalid use of void expression

Here some of the parameters I pass are not correct for the HP-UX pthread header
file definitions, possibly the NULL that I pass as the second parameter.
I looked in an online manual of HP-UX 10.30 that the second parameter
should be pthread_attr_default, if default attributes are wanted
for a pthread creation. You could try replacing the NULL on line 69
by pthread_attr_default.

It would help. If you can, please send them to [EMAIL PROTECTED]
(especially pthread.h).

Sorry, forgot to mention you should delete all .o files in subdirs. Type
in the innobase directory:
rm ./*/*.o
and only after that do the make.
Thank you for trying on HP-UX. On Solaris I was able to compile, but
obviously I still have overlooked some Posix thread subtleties.
Best regards,
Heikki
