Overview

This is Common IPS Build System (CIBS). It intend to replace all userland-hell known from OpenSolaris and OpenIndiana.

CIBS is inspired by Common Debian Build System

Major features are:

Makefile-based (need GNU make)
Modular design (include autotools.mk for GNU configure, or cmake.mk for CMake-based packages)
Tracking build dependencies
Building packages independently (no more terrible "consolidations" or "incorporations")

To create and publish an IPS package you need:

CIBS package installed (pkg:/developer/pkg/cibs)
Makefile describing what and how you are building
At least one canonical IPS manifest.

Look into directory examples for examples.

Best practices

Split development file and runtime

In contrast to some crazy distributions (like Solaris or Arch Linux) we do split runtime and development files (as Debian does).

Any shared library should be packaged into separate package reflecting library's soname, e. g. library/gmp10 includes libgmp.so.10. Nothing else. But library/gmp includes headers, man pages, maybe static libraries etc. - anything that required to build applications using GMP. Both packages - library/FOO and library/FOOxxx are built from the same source, and library/FOO must depend on library/FOOxxx in such a way:

depend fmri=pkg:/library/FOOxxx@$(ips-version) type=require
depend fmri=pkg:/library/FOOxxx@$(ips-version) type=incorporate

The trick is that IPS will use library/FOOxxx to fulfil runtime dependencies, and we will be allowed to perform smooth migration on newer library (e. g. library/FOOyyy) without breaking existing packages. Of course, newer library/FOO will depend on library/FOOyyy, but library/FOOyyy can be installed along with library/FOOxxx. Again, library/FOOyyy and library/FOOxxx must be installable together so none of them can ship docs, man pages or images or anything, but a shared library itself.

Another example is Node.js or Python. Use developer/nodejs and runtime/nodejs package for development files and runtime. runtime/nodejs includes only the binary - /usr/bin/nodejs - and maybe other runtime files, man pages etc.

CIBS modules

common.mk

This module defines common variables and targets. All other modules include this module, and it should not be included directly, unless you are doing something really special.

Targets provided by common.mk

All targets (but clean) provided by this module are abstract and do nothing. Other modules extend these targets. Each target has its annex target-stamp which does the real job. Each *-stamp is a file created with touch command. All internal dependencies are implemented through these "stamps", but developer can use basename for target, e. g. make unpack instead of make unpack-stamp.

Meaning of these targets depends on other included modules:

unpack - put sources into the source directory (./work/source by default),
patch - modify sources,
configure - configure sources, e. g. execute GNU configure or CMake,
build - build sources, e. g. compile with C compiler,
install - install files into proto directory.

Each target in the list above depends on previous target. Yes, except clean.

clean has a double-colon rule and by default it is:

clean::
    rm -f *-stamp
    rm -rf $(workdir)

Building many variants

common.mk defines a macro add-variant to extend above targets and to define related variables such as protodir.<variant>. Calling $(eval $(call add-variant,FOO)) will add dependencies to configure-stamp, build-stamp,install-stamp and define extra variables:

variants += FOO
protodir.FOO = $(workdir)/proto/FOO
builddir.FOO = $(workdir)/build/FOO

configure-stamp    : configure-FOO-stamp
build-stamp        : build-FOO-stamp
install-stamp      : install-FOO-stamp
%-FOO-stamp: variant = FOO

The add-variant macro is used by 32.mk and 64.mk modules for building 32-bit or 64-bit packages. You may want to use it for any other purpose, e. g. to compile Curl with OpenSSL or with GNU TLS. Standard modules, such as autotools.mk, take care of every variant defined. You can tune building by defining variables like configure-options.FOO, e. g.:

$(eval $(call add-variant,ssl))
$(eval $(call add-variant,gnu))

configure-options.gnu = --without-ssl --with-gnutls
configure-options.ssl = --with-ssl --without-gnutls

ips.mk

This module provides functions to work with IPS manifests and publish packages.

Targets provided by ips.mk

publish - publish IPS package into IPS repository
pre-publish - make everything required to publish (including downloading archive, patching, compiling, mogrifying manifests etc), but do not publish. Usefull for final verifications what is going into IPS repository. All intermediate and final manifests are in "work/manifests" directory.
build-dep - install build dependencies

Variables used by ips.mk

ips-repo - IPS repository to publish, e. g. make publish ips-repo=http://example.com:1234

Any variable defined in Makefile will be passed to pkgmogrify and can be used in IPS manifests (*.p5m). This is especially useful when with variable ips-version, which is by default = version. Example is OpenSSL, where version = 0.9.8x, but ips-version=0.9.8.23 (because letters are not allowed by IPS).

These variables passed additionally: build32 = # or empty, and build64 = # or empty. These variables can be used to cut off some line in package manifest (by commenting out). By default these vars are # (pound). If module 32.mk is included, build32 becomes '' (empty), so lines like:

$(build32) file path=usr/lib/libfoo.so.1

become uncommented. Same for modules 64.mk.

Other automatic variables are protodir.<variant> and builddir.<variant>. These variables hold paths to corresponding directories used to install or build package. <variant> can be, for example, 32 or 64. This allow exact specifying which file is requested, e. g.:

file $(builddir.32)/libfoo.so.1 path=usr/lib/libfoo.so.1

git.mk

Use this modules to get sources from Git repositories. With this module included targets download and unpack mean the same thing - clone git reporitory into source directory ("work/source"), then checkout given tag, commit or branch.

Makefile should define two variables:

git-url - URL of Git repository, used as git clone $(git-url) $(sourcedir)
git-checkout - Git tag, branch or commit; used as git checkout $(git-checkout)

For example see "examples/symlinks".

copy.mk

If this module is included, entire source tree will be copied into all requested building directories. This is useful for packages that do not support building out of source tree, such as zlib or openssl.
