1: Compiling ns_xml error

Posted by Jun Yamog on 08/02/01 10:43 AM

Hi,

I am trying to install OpenACS 4 and it ns_xml module of aolserver.

I got the ns_xml code from

http://acs-misc.sourceforge.net/nsxml.html

its version 1.4

Now since i use ximian gnome the libxml has been changed. make had en
error that it cant find the xml headers.

I made a soft link to the gnome xml headers:

<aolserver src>/include/libxml -> /usr/include/gnome-xml/

make still could not continue but hey it now gets the xml headers i
made a small progress. But i still can finish it.

Here the code:

gcc -I../aolserver/include -D_REENTRANT=1 -DNDEBUG=1 -g -fPIC -Wall
-Wno-unused -mcpu=i686 -DHAVE_CMMSG=1 -DUSE_FIONREAD=1
-DHAVE_COND_EINTR=1 -c -o ns_xml.o ns_xml.c
ns_xml.c: In function `xml_node_command':
ns_xml.c:1133: structure has no member named `children'
ns_xml.c: In function `Ns_ModuleInit':
ns_xml.c:1510: warning: implicit declaration of function `xmlMemSetup'
ns_xml.c:1510: `xmlFreeFunc' undeclared (first use in this function)
ns_xml.c:1510: (Each undeclared identifier is reported only once
ns_xml.c:1510: for each function it appears in.)
ns_xml.c:1510: parse error before `ns_free'
ns_xml.c:1519: warning: implicit declaration of function `xmlInitParser'
make: *** [ns_xml.o] Error 1

I looked at the nsxml.c source saw where it is but cant solve it.
Besides I maybe just using a broken nsxml.c

Can someone help me?

I use an (admittedly rather old!) GNOME setup here. What I did was just install libxml2 and libxml2-devel RPMs; there was no conflict with the pre-existing libxml-1.8.10-0_helix RPM.

If that will work for your (probably newer) GNOME installation too, it should avoid all the need for editing the Makefile, etc.

Hi Jonathan,

Thanks for the great help. Downloaded the SRPMs so I would know if it
would run my new libs. The rpms compiled, nsxml compiled... alright!!!!!

So folks.... read the instructions. libxml2

I don't know why I cannot install the rpms (libxml2 and libxml-devel) downloaded from xmlsoft.org, the package manager always complain "...only packages with major numbers <= 3 are supported by this version of RPM". Is my package manager too old (version3)? Any suggestion?

Hi,

I use rpm ver 4. on both RH6.2 and RH7.1 i suggest you upgarde your
rpms. There is an instruction at Redhat to upgrade your rpm its not
straight rpm upgrade. You have to upgrade your db3 ,etc.

Thanks. I finally get it done by downloading and compiling the source of libxml2. One more question: is libxml2-devel necessary if I just want nsxml.so without XSLT support?

You only need libxml2-devel to (for example) recompile libxslt.
All you need for nsxml.so and OpenACS 4.x is libxml2; however, when I asked about the need for libxslt support, I was advised by folks here to put libxslt support into my RPMs -- some folks think OpenACS 4 may eventually use some of the XSLT stuff, either by default or when some OpenACS 4.x users want to customize it to do so.

Grabbing the libxslt-1.0.3 SRPM and recompiling it doesn't take all that long.

Eventually I dig out how to install nsxml.so with XSLT in my Redhat6.2 with rpm3:

first of all, you have to upgrade rpm3 to rpm4:
- do a rpm --rebuilddb is recommended before upgrading;
- download 3 db3***6.x***.rpm packages and 5 related packages: rpm rpm-devel, rpm-build, rpm-python, popt from rpm.org or redhat
- install the 3 db3 packages first, then the remaining 5.
- do a rpm --rebuilddb to convert db1 to db3.

then you can install libxml2, libxm2-devel and libxslt with the upgraded rpm4.
