gst-plugins-base-0.10.32: GST_DISABLE_XML=1 doesn't work in gstsubparse.c

[bcxa sz]

Hi Developers,

I have cross compiled gstreamer on embedded system. And I have below
flags in gst-plugins-base-0.10.32/gst/subparse/Makefile:
GST_DISABLE_ALLOC_TRACE = 1
GST_DISABLE_GST_DEBUG = 1
GST_DISABLE_LOADSAVE = 1
GST_DISABLE_PARSE = 1
GST_DISABLE_PLUGIN = 1
GST_DISABLE_REGISTRY = 1
GST_DISABLE_TRACE = 1
GST_DISABLE_XML = 1

And look at the gstsubparse.c:
#ifndef GST_DISABLE_XML
    case GST_SUB_PARSE_FORMAT_SAMI:    
      self->parse_line = parse_sami;
      sami_context_init (&self->state);
      return gst_caps_new_simple ("text/x-pango-markup", NULL);
#endif

This piece of code is assumed not to get compiled. But this is not
true and it still get compiled.

And it seemed that GST_DISABLE_XML flag is not given to compiler with -D.

Anybody know this?

best regards

BCXA

Maybe you should try the latest release, which is 0.10.35.

You are setting Makefile variables here. These have nothing to do with
#ifdef and #ifndef.

Those defines would usually be in config.h in the top-level directory
(created and set by configure dependent on whether libxml2 development
files + headers have been found or not).

Hi Tim,

I attached my config.h here and I didn't see the defination.

All the Makefile and configure.h is generated automatically. And I
have a/v working on my embedded system with compiled gstreamer
library.

Just had this problem when I try to add subtitle support.

best regards

Sorry, I didn't read closely enough. The GST_DISABLE_XML define comes
from the GStreamer core includes (gst/gstconfig.h). It should be set by
default, unless you built GStreamer core with --disable-loadsave (and
maybe other switches, don't remember exactly).

And in gstconfig.h, I didn't see these flags are set and all is
commented like below.
====================================================================
/* trick gtk-doc into believing these symbols are defined (yes, it's ugly) */
#if 0
#define GST_DISABLE_GST_DEBUG 1

Checked further down? there should be something like:

/**
 * GST_DISABLE_XML:
 *
 * Configures the use libxml2. This setting is derived from the settings
of
 * %GST_DISABLE_LOADSAVE and %GST_DISABLE_REGISTRY (in the xml registry
case).
 */
/* #undef GST_DISABLE_XML */

Yes, I saw this piece of code and it is commented. And after this,

/***** Deal with XML stuff, we have to handle both loadsave and registry *****/
/* FIXME: move include to where we need it */
/*#if (! (defined(GST_DISABLE_LOADSAVE) && defined(GST_DISABLE_REGISTRY)) )*/
#ifndef GST_DISABLE_XML
#ifndef GST_DISABLE_DEPRECATED
# include <libxml/parser.h>
#endif
#else
  /* FIXME: 0.11 (replace by GST_DISABLE_XML) */
# define GST_DISABLE_LOADSAVE_REGISTRY
#endif

But I still can not see where GST_DISABLE_XML defined.

And I have one question on how GST_DISABLE_XML is set, check which condition.

I looked at the gstreamer on Fedor14. Fedora14 is also use libxml2 but
why GST_DISABLE_XML = 0?

My embedded system is also use libxml2 but GST_DISABLE_XML = 1.

Sorry, I am not familiar with gstreamer auto configure. And any
document on this?

With some close looking, I suspect this may be due to my build issue.

in gst-plugins-base-0.10.32/configure
==========================================================================
GST_CONFIGPATH=`$PKG_CONFIG --variable=includedir
gstreamer-0.10`"/gst/gstconfig.h"

  grep >/dev/null "#undef GST_DISABLE_XML" $GST_CONFIGPATH
  if test $? = 0; then
    GST_DISABLE_XML=0
  else
    GST_DISABLE_XML=1
  fi

 It should search the gstreamer-0.10.32/gst/gstconfig.h to find
whether have "#undef GST_DISABLE_XML". And look at the
gstreamer-0.10.32/gst/gstconfig.h:
=========================================================================
/**
 * GST_DISABLE_XML:
 *
 * Configures the use libxml2. This setting is derived from the settings of
 * %GST_DISABLE_LOADSAVE and %GST_DISABLE_REGISTRY (in the xml registry case).
 */
/* #undef GST_DISABLE_XML */

Code is there. So it means that GST_DISABLE_XML should be 0, not 1.
Unless, the gstconfig.h is not found. This is what I suspected.

Then I configure gst-plugins-base-0.10.32 again and found:
========================================================
grep: /usr/include/gstreamer-0.10/gst/gstconfig.h: No such file or directory
grep: /usr/include/gstreamer-0.10/gst/gstconfig.h: No such file or directory

I think I have found the reason:

The current command line has the parameter --prefix=/usr. It is
correct if from the embedded system target point of view.

But when configure gst-plugins-base-0.10.32,

in gst-plugins-base-0.10.32/configure
==========================================================================
GST_CONFIGPATH=`$PKG_CONFIG --variable=includedir
gstreamer-0.10`"/gst/gstconfig.h"

It will try to find the includedir with pk-config
[root@fedora14 gst-plugins-base-0.10.32]# cat
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/lib/pkgconfig/gstreamer-0.10.pc
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/gstreamer-0.10
toolsdir=${exec_prefix}/bin
pluginsdir=${libdir}/gstreamer-0.10
datarootdir=${prefix}/share
datadir=${datarootdir}
girdir=${datadir}/gir-1.0
typelibdir=${libdir}/girepository-1.0

Name: GStreamer
Description: Streaming media framework
Requires: glib-2.0, gobject-2.0, gmodule-no-export-2.0, gthread-2.0, libxml-2.0
Version: 0.10.34
Libs: -L${libdir} -lgstreamer-0.10
Cflags: -I${includedir}
==============================================================================

But unfortunately, it will try to find the header file at host
/usr/include/gstreamer-0.10/gst/gstconfig.h. But it should find this
header file at:
===============================================================================
[root@fedora14 gst-plugins-base-0.10.32]# ls
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/gstreamer-0.10/gst/gstconfig.h
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/gstreamer-0.10/gst/gstconfig.h
===============================================================================

So I think this one should be gstreamer cross compile issue. Do you
have some suggestion to fix?

This is an issue with your dev environment setup then. Try
adding /opt/STM/STLinux-2.4/devkit/sh4/target/usr/lib/pkgconfig to
PKG_CONFIG_PATH (or use the --with-pkg-config-path configure option)

Cheers

Hi Tim,

My PKG_CONFIG_PATH is correct. It will correctly find
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/lib/pkgconfig/gstreamer-0.10.pc.

And in this .pc, the includedir is /user/include/gstreamer-0.10. This
includedir is correct if from the target point of view.

But the issue is that, when configure gst-plugins-base-0.10.32, in
configure file:

GST_CONFIGPATH=`$PKG_CONFIG --variable=includedir
gstreamer-0.10`"/gst/gstconfig.h"

Then GST_CONFIGPATH will be
/usr/include/gstreamer-0.10/gst/gstconfig.h. This is the host file
system path.

Not target file system path.

My solution is to add one more environment variable:
===============================
export PKG_PREFIX_BASE=/opt/STM/STLinux-2.4/devkit/sh4/target/
GST_CONFIGPATH=$PKG_PREFIX_BASE`$PKG_CONFIG --variable=includedir
gstreamer-0.10`"/gst/gstconfig.h"

Then the GST_CONFIGPATH will be
/opt/STM/STLinux-2.4/devkit/sh4/target/usr/include/gstreamer-0.10/gst/gstconfig.h

I think this is the issue of gstreamer, not adapt to cross compile.
Please let me know if I am wrong.
