help with inter-library dependencies and "+z or +Z" option (gcc)

[Frank Mattes]

Hi all,

I tried to compile the program "pybliographer" under hp-ux. I get the
following warning,

*** Warning: inter-library dependencies are not known to be supported.
*** All declared inter-library dependencies are being dropped.
*** The inter-library dependencies that have been dropped here will be
*** automatically added whenever a program is linked with this library
*** or is declared to -dlopen it.

(some compiling output)

Followed by the error message

gcc -fpic -I/user/developr/pybliographer-1.0.0/compiled/../bibtex
-I/opt/glib/lib/glib/include -I/opt/glib/include -I/opt/recode/include
-I.. -g -O2 -I/user/developr/python/include/python1.5

ld: DP relative code in file ../bibtex/.libs/libbibtex.a(bibtex.o) -
shared library must be position
independent. Use +z or +Z to recompile.
gmake[2]: *** [_bibtexmodule.sl] Error 1

I could't find a compiler option +z or +Z for gcc
Is there anyone who could explain to me what's going wrong ?

I appreciate any help

Regards

Frank

You didn't say which version of HPUX you are using, which may be of interest.
The +z/+Z options AFAIK are relevant to HPUX only, not to gcc or binutils. If
your gcc is set up the usual way, using gnu as, only the HPUX linker is used
from the standard HPUX set of tools. You could check 'man ld' to see if those
options are relevant to HPUX ld. Sorry, I am no longer employed where I had
access to HPUX.

I suppose you should be investigating whether this package has any HPUX version
dependencies, whether it expects you to use gcc built --with-gnu-as or using
the HPUX as, whether your message is simply a warning or is preventing further
progress...

Didn't I already answer a similar question this morning? :-)
+z = -fpic
+Z = -fPIC

PIC = position independant code

Best regards,
