+# Manually Building X and Beyond
+
+We try something **ill-advised**, we build a separate version of X.org in another directory, say */opt/xbeta*,
+on the same machine where we have installed the latext pkgsrc. We do this because we have no choice but to
+use the graphics hardware on this machine, but the risk is that it is very easy to link the wrong libraries
+from pkgsrc.
+
+## Disclaimer
+
+The following notes describe alterations to one's system that may leave the graphical user interface based
+on X.org unusable. Use at one's own risk. Because the risk of damaging one's system is so great, I refuse
+to provide ready-to-run scripts.
+
+## Installing from pkgsrc
+
+### GNU m4 1.4.14 and bison 2.4.2
+
+Patch both *devel/m4* and *devel/bison* using the patch idea from:
+<http://www.netbsd.org/cgi-bin/query-pr-single.pl?number=43098>
+
+Unfortunately the problems are in the *work* directories so that one needs the knowledge from
+<http://www.netbsd.org/docs/pkgsrc/components.html>
+to even get the patches to be applied.
+
+Install *pkgtools/pkgdiff*.
+
+### gstreamer 0.10
+
+As of 2010-05-09, I find it necessary on x86_64 to use the following patch for
+pkgsrc gstreamer0.10, an eventual dependency of the full xfce desktop:

+
+### expat and gettext
+
+We start with installing into */opt/xbeta* [expat 2.0.1](http://sourceforge.net/projects/expat/)
+and [gettext 0.17](http://www.gnu.org/software/gettext/).
+
+### Git repository for most of X.org
+
+We use the following listing:
+
+[freedesktop.org git repository browser](http://cgit.freedesktop.org/)
+
+One can easily script getting, updating, and building the projects listed on that page.

+### libxcb problem with Python 2.6 cElementTree
+
+Library *xcb/libxcb* unfortunately needs to be built early and there is a catch for
+using pkgsrc Python 2.6. Unfortunately at the current time not all of
+*cElementTree* appears to be functional; therefore, one needs a patch similar to
+

+### FreeType 2
+
+We install [FreeType 2.3.12](http://www.freetype.org/). It appears that *GNUMAKE=gmake* is required.
+Most of the X.org projects use *autogen.sh*, but here we use a standard call to *configure* somewhat
+similar to:
+
+ export ACLOCAL="aclocal -I ${PREFIX}/share/aclocal"
+ export PKG_CONFIG_PATH="${PREFIX}/lib/pkgconfig"
+ GNUMAKE=gmake ./configure --prefix=${PREFIX} CPPFLAGS="-I${PREFIX}/include -I${PREFIX}/X11/include" LDFLAGS="-L${PREFIX}/lib -Wl,-rpath -Wl,${PREFIX}/lib -L${PREFIX}/X11/lib -Wl,-rpath -Wl,${PREFIX}/lib/X11"
+
+where *$PREFIX* is where we install X.org, say */opt/xbeta*,
+the first two exports of *ACLOCAL* and *PKG_CONFIG_PATH* occur for most X.org projects,
+*CPPFLAGS* and *LDFLAGS* ensure that the *$PREFIX* include directories and library paths
+are used, and *-Wl,-rpath ...* is an incantation that ensures that previous built
+*libtool* libraries can be used.

+### Graphics Image Formats
+
+*libpng* <http://www.libpng.org/pub/png/libpng.html> version *1.4.2*
+can be installed using *autogen.sh* and then *configure*, in contrast to
+the X.org projects that pass parameters from *autogen.sh* to run *configure* automatically.
+
+Independent JPEG Group's library <http://www.ijg.org/> version *8b* can be installed
+using *configure* alone (there is no autogen.sh).
+
+LibTIFF <http://www.remotesensing.org/libtiff/> has a recommended dependency on jpeg.
+LibTIFF version 3.9.2 can be installed using *autogen.sh* and then *configure*.
+
+Running
+ gmake check
+after building any of the above three projects appears to produce passes tests.
+
+### XML
+
+#### libxml2
+
+*autogen.sh* calls *configure*
+
+11 tests fail after *gmake check*
+
+### Cairo
+
+Seems to require
+
+ export LDFLAGS="-L${PREFIX}/lib -Wl,-rpath -Wl,${PREFIX}/lib -L${PREFIX}/lib/X11 -Wl,-rpath -Wl,${PREFIX}/lib/X11"
+ export CPPFLAGS="-I${PREFIX}/include -I${PREFIX}/X11/include"
+
+When using gcc 4.1.2, *gmake check* gives:
+
+ LINK check-link
+ ./.libs/libcairo.so: undefined reference to `__umodti3'
+ ./.libs/libcairo.so: undefined reference to `__udivti3'
+
+When using *CCVER=gcc44* to force gcc 4.4, one obtains the worse:
+
+ CHECK cairo.h
+ cc1: error: unrecognized command line option "-Wlogical-op"
+ CHECK cairo-deprecated.h
+ cc1: error: unrecognized command line option "-Wlogical-op"
+ ...
+
+The problem is 128-bit division using gcc 4.1.2 as discussed earlier. One can examine
+*src/cairo-wideint.c* and see the telltale code enclosed in an if test for *HAVE_UINT128_T*
+with 128-bit division if defined.
+
+### Pango
+
+Install *gnome-common* first, required.
+
+If Cairo is not built with *CCVER=gcc44*, obtain build error similar to
+
+ CCLD pango-view
+ /opt/xcatch/lib/libcairo.so: undefined reference to `__umodti3'
+ /opt/xcatch/lib/libcairo.so: undefined reference to `__udivti3'
+ gmake[3]: *** [pango-view] Error 1
+
+Following patch corrects an API change not propagated to the test for *gmake check*
+<https://bugzilla.gnome.org/show_bug.cgi?id=619456>
+
+Not including patch itself because there are tabs. But edit file *pango/pangoft2.def*
+and change
+ pango_fc_font_create_metrics_for_context
+to
+ pango_fc_font_create_base_metrics_for_context
+
+### GObject Introspection
+
+*cElementTree* is changed to *ElementTree* in files
+*giscanner/girparser.py*, *giscanner/glibtransformer.py*, and *giscanner/scannermain.py*.
+
+Using *pkg_alternatives* for a python wrapper fails as a script is generated with
+
+ #! /usr/pkg/bin/python
+
+ import os
+ import sys
+
+A shell script cannot use another shell script as its interpreter.
+What works for now is to manually create */usr/pkg/bin/python* as a symlink to */usr/pkg/bin/python2.6*.
+
+### gtk+
+
+*gobject-introspection* is listed as a dependency but can be avoided.
+Use option *--disable-introspection* to avoid an error
+
+ checking for gobject-introspection... yes
+ ./configure: ${INTROSPECTION_GIRDIR/...}: Bad substitution
