New submission from Michael Osipov <1983-01...@gmx.net>:
I do compile Python from master on HP-UX with aCC:
# echo $LDFLAGS $CPPFLAGS
-L/opt/ports/lib/hpux32 -I/opt/ports/include
UNIX_STD=1998 LDFLAGS="$LDFLAGS -lreadline" CPPFLAGS="-I$PREFIX/include/ncurses
$CPPFLAGS" ./configure --prefix=/opt/python \
--libdir=/opt/python/lib/hpux32 --with-system-expat
--with-openssl=/opt/openssl
having libs in hpux32 or hpux64 is a convention on this platform. When Python
is installed the following happens:
$ /opt/python/bin/python3
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Python 3.8.0a3+ (default, Apr 30 2019, 12:09:29) [C] on hp-ux11
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/opt/python/lib/python38.zip', '/opt/python/lib/python3.8',
'/opt/python/lib/lib-dynload',
'/net/home/osipovmi/.local/lib/python3.8/site-packages',
'/opt/python/lib/python3.8/site-packages']
I don't see hpux32 anywhere here. Though all shared objects are there.
Reconfiguring:
# echo $LDFLAGS $CPPFLAGS
-L/opt/ports/lib/hpux32 -I/opt/ports/include
UNIX_STD=1998 LDFLAGS="$LDFLAGS -lreadline" CPPFLAGS="-I$PREFIX/include/ncurses
$CPPFLAGS" ./configure --prefix=/opt/python \
--with-system-expat --with-openssl=/opt/openssl
gives me the expected result:
$ /opt/python/bin/python3
Python 3.8.0a3+ (default, Apr 30 2019, 12:21:15) [C] on hp-ux11
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/opt/python/lib/python38.zip', '/opt/python/lib/python3.8',
'/opt/python/lib/python3.8/lib-dynload',
'/net/home/osipovmi/.local/lib/python3.8/site-packages',
'/opt/python/lib/python3.8/site-packages']

It pretty much seems like '--libdir' is not correctly passed down to the
installation.
I can see that at least this is wrong:

I have changed those files manually by adding '/hpux32' everywhere and ran
configure with custom libdir:
no avail. 'lib/python' will still be used. If this cannot be changed, a warning
should be issued with ./configure that custom libdir will lead to loading
issues.
