(Perl) XML::LibXML compilation error

[Samuel PHAN]

Hi, I'm trying to install the perl lib XML::LibXML that relies on libxml2.

Here are my environement variables & so:

% perl --version

This is perl, v5.10.1 (*) built for PA-RISC2.0

libxml2 not found
Try setting LIBS and INC values on the command line
Or get libxml2 from
http://xmlsoft.org/
If you install via RPMs, make sure you also install the -devel
RPMs, as this is where the headers (.h files) are.

Also, you may try to run perl Makefile.PL with the DEBUG=1 parameter
to see the exact reason why the detection of libxml2 installation
failed or why Makefile.PL was not able to compile a test program.

I don't understand why there is this error:

/usr/lib/dld.sl: Can't open shared library: libiconv.sl
/usr/lib/dld.sl: No such file or directory

The lib is right in the place:

% ll /usr/local/lib/libiconv*
-rw-r--r-- 1 root sys 943920 Jan 31 2004 /usr/local/lib/libiconv.a
-rw-r--r-- 1 root sys 788 Jan 31 2004 /usr/local/lib/libiconv.la
-r-xr-xr-x 1 root sys 929792 Jan 31 2004 /usr/local/lib/libiconv.sl*

I've set the env var:

$LD_PRELOAD=/usr/lib/libpthread.sl

cause if I don't, I have this error during the compilation:

/usr/lib/dld.sl: Can't shl_load() a library containing Thread Local Storage: /usr/lib/libpthread.1
/usr/lib/dld.sl: Exec format error

---

Do you know why it can't find the libiconv.sl ?

Thanks in advance,

[Dennis Handly]

What does "file usr/local/lib/libiconv.sl" show?

>Do you know why it can't find the libiconv.sl?

Do you have the right bitness in that shlib?
Do you have R and X permissions for /usr /usr/lib /usr/local/lib?

[Samuel PHAN]

Hi Dennis,

Thanks for your reply.

In fact, it seems that I found what to do to make it works:

export LDOPTS="+s -L/usr/local/lib -L/usr/lib"

I've read this there:

http://hpux.connect.org.uk/hppd/cgi-bin/wwwtar?/hpux/Development/Libraries/libiconv-1.13.1/libiconv-1.13.1-src-11.11.tar.gz+libiconv-1.13.1/HPUX.Install+text

There are some missing dependencies now (XML::NamespaceSupport & XML::SAX), but this problem seems to be behind ;-)

[Dennis Handly]

>it seems that I found what to do to make it works:
export LDOPTS="+s -L/usr/local/lib -L/usr/lib"

(Since -L/usr/lib is the default, please leave it off.)
What are you building with this?
I guess I assumed that +s was already being used since perl would have to have it.

But if it is your shlib that needs libiconv, then you need +s.

[Samuel PHAN]

Hi Dennis,

Thanks for your replay, and sorry to reply so late.

To resume what I've done to make the compilation of the perl lib XML::LibXML, was just :

export LD_PRELOAD=/usr/lib/libpthread.sl
export LDOPTS="$LDOPTS +s -L/usr/local/lib -L/usr/lib"

Then :

perl Makefile.PL PREFIX=/path/to/usr
make
make test
make install

You may be right about the "-L/usr/lib" that may be not required, but I just write here what I've done and it works.

Thank you for your replies.

[Samuel PHAN]

Before compilation, type:

export LD_PRELOAD=/usr/lib/libpthread.sl
export LDOPTS="$LDOPTS +s -L/usr/local/lib -L/usr/lib"

Then:

perl Makefile.pl PREFIX=/path/to/usr
make
make test
make install

That's all.
