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: --------------
1.11 david 10: Xenocara is the name chosen for OpenBSD's version of X. It's
1.1 matthieu 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
1.11 david 14: party packages and some software maintained by OpenBSD developers.
1.1 matthieu 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:
1.5 matthieu 58: Quick startup guide
59:
60: The following steps will build and install everything for the first time.
61:
1.12 ! jsg 62: mkdir -p /usr/xobj
1.7 matthieu 63: cd xenocara
1.5 matthieu 64: make bootstrap
65: make obj
66: make build
67:
68: If you want to use another obj directory see below.
69:
1.2 matthieu 70: Requirements
71:
72: A freshly checked out xenocara tree is buildable without any external
73: tool. However if you start modifying things in the automake build
74: system used by many packages, you will need to have the following
1.3 matthieu 75: GNU autotools packages installed:
1.2 matthieu 76:
77: - automake 1.9 (devel/automake/1.9)
78: - autoconf 2.59 (devel/autoconf/2.59)
1.6 matthieu 79: - metaauto 0.6 (or later) (devel/metaauto)
1.2 matthieu 80: - libtool 1.5.22 (or later) (devel/libtool)
81:
1.8 matthieu 82: Path
83:
84: To build Xenocara, you need to have /usr/X11R6/bin in your PATH.
85:
1.2 matthieu 86: Sudo
87:
88: If the SUDO variable points to your sudo(8) binary in /etc/mk.conf,
89: 'make build' can be run as a normal user. It will raise its privileges
90: whenever needed with sudo. Otherwise, you need to run make build as
91: root.
92:
1.3 matthieu 93: If you have installed the full Xenocara X sets on your system, you
94: don't need to build all of Xenocara to patch one element. You can go
1.2 matthieu 95: to any module sub-directory and run 'make build' from there.
96:
1.8 matthieu 97: Source directory
98:
99: The variable XSRCDIR can be set either in the environment or in
1.9 matthieu 100: /etc/mk.conf to point to the xenocara source tree, in case you keep it
1.10 matthieu 101: in a non-standard directory (the default is /usr/src/xenocara).
1.8 matthieu 102:
1.2 matthieu 103: Objdirs
104:
105: Xenocara supports objdirs (and it's even the recommended way to build
106: things). Just run 'make obj' at any level before 'make build' to make
1.4 matthieu 107: sure that the object directories are created.
1.8 matthieu 108: XOBJDIR defines the default obj directory that is used.
1.2 matthieu 109:
110: Shadow trees
111:
112: Alternatively, the old 'lndir(1)' method can still be used to build
1.3 matthieu 113: Xenocara outside of its source tree. Just don't use 'make obj' in this
1.2 matthieu 114: case.
115:
116: o Regenerating configure scripts
117: ------------------------------
118:
119: Whenever you touched an import file for GNU autotools (Makefile.am,
120: configure.ac mostly), you need to rebuild the configure script and
121: makefiles skeletons. For that use the following command:
122:
123: env XENOCARA_RERUN_AUTOCONF=Yes make -f Makefile.bsd-wrapper build
124:
125: You can also set XENOCARA_RERUN_AUTOCONF in /etc/mk.conf to force
126: regeneration of configure scripts in every component.
