Hello

Thanks Daniel for the help.
I ve installed libxml-2.1.0 on a distrib Suse62 and all seems to happen
well. During the make install, I got the message:

>Libraries have been installed in:
> /usr/local/lib
>
>If you ever happen to want to link against installed libraries
>specify the full pathname of the library, or use `-LLIBDIR'

I didn't take care about it because "/usr/local/lib" was included
correctly in my file "/etc/ld.so.conf".

So I did the compilation of the examples with Daniel's Makefile and the
compilation seems also to happen well.

>Makefile used:

>CC=gcc
>CFLAGS=`xml-config --cflags`
>LDFLAGS=`xml-config --libs`

>clean:

>
>gjobread: gjobread.o
> $(CC) -o gjobread gjobread.o $(LDFLAGS)
>
>test: gjobread
> ./gjobread gjobs.xml

But during the execution I got the following message:

cyrix150:~/xml/libxml2-2.1.0/example # gjobread gjobs.xml
gjobread: error in loading shared libraries: libxml.so.2: cannot open
shared object file: No such file or directory

I have checked if all these libraries were installed and I have found
them in "/usr/local/lib". I haven't found libxml.so.2 in "usr/lib".

I ve tried to compile with a manual cde but the compilation fell also
because the system seems to use the libxml.a localised in "/usr/lib/"
instead of "/usr/local/lib". I don't know how to force the system use
the "/usr/local/lib".

        gcc -o gjobread gjobread.c -I/root/xml/libxml2-2.1.0 -lxml
->
/tmp/ccE5nqHP.o: In function `main':

collect2: ld returned 1 exit status

I will try to install "libxml-2.1.0" on a distrib Rdhat62 to check if
the pb is similar.

Pb not easy. Thanks for the help.
Bye
