Yes, that is one solution, however doing it systematically for each and

Maybe you could add '#define vasprintf gnutls_vasprintf' in your
config.h when building GnuTLS?  I'm not sure it will work, but something
like that will be necessary to fully solve this problem.

  

Up to now only the vasprintf seems to have problems. So It's not difficult to change the code.

I edited the Makefile in doc/example changing

LIBS =  -lws2_32

to

LIBS =  -lws2_32 ../../gl/.libs/libgnu.a


and this issue disappeared.
    

I'm not sure if it will solve this, but I changed the order of libgnu.la
in Makefile.am.  Please test tomorrow's snapshot.

  

In my opinion it fixes the issue. Moreover if you use the following link

http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Gnu/gnutls-2.3.4/gnutls-2.3.4-src-11.11.tar.gz+gnutls-2.3.4/HPUX.Install+text

you find some suggestion to get GnuTls compiled in HPUX for 2.3.4. There's the following comment

* doc/examples/Makefile.in:
  - Use ../../gl/.libs/libgnu.la at the end of the libtool link line
    to link examples, rather than ../../gl/libgnu.la in the middle of the
    line. This avoids a missing rpl_strerror symbol when linking on the
    Itanium platform.

So I'm not alone :-)

To build the manual, you need a newer texinfo.  However, building it
shouldn't be required unless you modified any source files that is used
by the manual.  Possibly you have done that...  I think this should go
away when all your other build problems are solved in the official
distribution.
  

I'll update the texinfo package. In the meantime I can skip the doc building using an empty Makefile

all:
check:

(quick and dirty, but better than an error)

So now I'm able to get gnutls compiled . Here's the full story

I get gnutls-2.3.5.tar.bz2 then

1) libgpg-error

./configure --disable-shared --disable-rpath
make
make check
make install


2) libgcrypt

./configure --disable-shared --disable-asm --enable-random=w32 --disable-dev-random

make
make check
make install

3) GnuTLS

Edit the sources changing any vasprintf to gnutls_vasprintf (stdio.in.h, vasprintf.c, asprintf.c and gnutls_str.c)
Edit the config.h.in to have #define HAVE_ALLOCA 0 and #define HAVE_ALLOCA_H 0

./configure --disable-shared --disable-rpath --disable-cxx --disable-guile

Edit config.h to have #define HAVE_ALLOCA 0 (configure sets HAVE_ALLOCA 1)
Edit Makefile in doc to do nothing
Edit Makefile in doc/example adding ../../gl/libgnu.la to LIBS

4) make

Yup, it does! The compilation ended without any error, just two warnings only. All other issues disappear. The warnings are

I think the compiler is right. The two variable are used in

pkix_asn1_tab.c
gnutls_global.c

in both files you use the extern qualifier, but in pkix_asn1_tab.c you also assign a "value". Wouldn't it be better to remove the extern qualifier in
pkix_asn1_tab.c? Ok is a very minor issue but avoid two warnings.

So is this the end of the story? Unfortunately no!!When I did 'make check' I got

Googling the internet I  got the opinion that this may be related to isprint(), I'm not sure anyway. Is the following recommandation (from HPUX suggestions) relevat to the failure?

* lib/x509/output.c:
  - The isprint() routine on Itanium platforms seemed to like printing
    8-bit chars (possibly to do with the sign of the char?), so changed it
    to simply print any char between ' ' and '~'. Without this change,
    Itanium's "gmake check" fails one of the checks.

Just for verification I repeated the whole process twice (from scratch) using

CFLAGS=-O2

and

CFLAGS=

getting exactly the same results

So the optimizer is not involved.

I absolutely need your help to fix the latest issue.
