2: Notes on building Xenocara for OpenBSD X hackers
3:
4: This document presents some techniques that can be useful for people
5: wanting to hack the xenocara tree. It assumes some basic knowledge of
6: the OpenBSD build system, as described in the release(8) manual page.
7:
8: o About Xenocara
9: --------------
10: Xenocara is the name choosen for OpenBSD's version of X. It's
11: currently based on X.Org 7.2 and its dependencies. The goal of
12: Xenocara is to provide a framework to host local modifications and to
13: automate the build of the modular X.Org components, including 3rd
14: party packages and some software maintained by OpenBSD developpers.
15:
16: o Source tree
17: -----------
18:
19: The organisation of the xenocara directory follows the general
20: organisation used in X.Org:
21:
22: - app: X applications and utilities
23: - data: various data files (keyboard mappings and bitmaps)
24: - doc: documentation
25: - driver: input and video drivers
26: - font: fonts
27: - lib: libraries
28: - proto: X protocol headers
29: - util: utilities that don't fit anywhere else
30: - xserver: the source for the X servers
31:
32: In addition Xenocara uses the following directories:
33:
34: - dist: contains the Mesa sources, shared by lib and xserver above
35: - distrib: all binary distribution related tools and data
36: - etc: mtree(8) data files
1.3 ! matthieu 37: - share: make(1) configuration for Xenocara
1.1 matthieu 38:
1.2 matthieu 39: At the top-level directory two files describe the individual
1.3 ! matthieu 40: components of Xenocara:
1.1 matthieu 41:
1.2 matthieu 42: - MODULES lists all X.Org components (imported from the X.Org
43: distribution at http://xorg.freedesktop.org/archive/)
1.3 ! matthieu 44: - 3RDPARTY lists all 3rd party software components provided in Xenocara,
1.2 matthieu 45: either as dependencies of the X.Org software, or as
46: complements to it to provide a more useable default
47: environment.
48:
49: o Compiling and installing
50: ------------------------
51:
1.3 ! matthieu 52: Xenocara is made up of more than three hundred different
! 53: independent packages that need to be build and installed in the right
! 54: order, especially while bootstrapping (while /usr/X11R6 is still
! 55: empty). The Xenocara Makefiles take care of that using the 'build'
1.2 matthieu 56: target.
57:
58: Requirements
59:
60: A freshly checked out xenocara tree is buildable without any external
61: tool. However if you start modifying things in the automake build
62: system used by many packages, you will need to have the following
1.3 ! matthieu 63: GNU autotools packages installed:
1.2 matthieu 64:
65: - automake 1.9 (devel/automake/1.9)
66: - autoconf 2.59 (devel/autoconf/2.59)
67: - pkg-config 0.19 (or later) (devel/pkgconfig)
68: - libtool 1.5.22 (or later) (devel/libtool)
69:
70: Sudo
71:
72: If the SUDO variable points to your sudo(8) binary in /etc/mk.conf,
73: 'make build' can be run as a normal user. It will raise its privileges
74: whenever needed with sudo. Otherwise, you need to run make build as
75: root.
76:
1.3 ! matthieu 77: If you have installed the full Xenocara X sets on your system, you
! 78: don't need to build all of Xenocara to patch one element. You can go
1.2 matthieu 79: to any module sub-directory and run 'make build' from there.
80:
81: Objdirs
82:
83: Xenocara supports objdirs (and it's even the recommended way to build
84: things). Just run 'make obj' at any level before 'make build' to make
85: sure the object directory is created.
86:
1.3 ! matthieu 87: XXX support for objdirs needs to be improved! XXX
1.2 matthieu 88:
89: Shadow trees
90:
91: Alternatively, the old 'lndir(1)' method can still be used to build
1.3 ! matthieu 92: Xenocara outside of its source tree. Just don't use 'make obj' in this
1.2 matthieu 93: case.
94:
95: o Regenerating configure scripts
96: ------------------------------
97:
98: Whenever you touched an import file for GNU autotools (Makefile.am,
99: configure.ac mostly), you need to rebuild the configure script and
100: makefiles skeletons. For that use the following command:
101:
102: env XENOCARA_RERUN_AUTOCONF=Yes make -f Makefile.bsd-wrapper build
103:
104: You can also set XENOCARA_RERUN_AUTOCONF in /etc/mk.conf to force
105: regeneration of configure scripts in every component.
