pkgconf - compiler and linker configuration for development frameworks
|
|
----------------------------------------------------------------------
|
|
|
|
1. General summary.
|
|
|
|
pkgconf is a program which helps to configure compiler and linker flags for
|
|
development frameworks. It is similar to pkg-config, but was written from
|
|
scratch in Summer of 2011 to replace pkg-config, which now needs itself to
|
|
build itself (or you can set a bunch of environment variables, both are
|
|
pretty ugly.)
|
|
|
|
Implementations of pkg-config, such as pkgconf are typically used with the
|
|
PKG_CHECK_MODULES autoconf macro. As far as I (nenolod) know, pkgconf is
|
|
compatible with all known variations of this macro. However, I have not
|
|
extensively tested yet for compatibility. pkgconf detects at runtime
|
|
whether or not it was started as 'pkg-config', and if so, attempts to set
|
|
program options in a way where it's behaviour should be similar.
|
|
|
|
In terms of the autoconf macro, it is possible to specify the PKG_CONFIG
|
|
environment variable, so that you can test pkgconf without overwriting your
|
|
pkg-config binary. (hint: export PKG_CONFIG=/usr/bin/pkgconf) However,
|
|
if you do this, it will be running in native mode, so you may have some very
|
|
strange results as the dependency graph is compiled differently in native
|
|
mode.
|
|
|
|
2. Technical design.
|
|
|
|
pkgconf builds an acyclic directed dependency graph. This allows for the user
|
|
to more conservatively link their binaries -- which may be helpful in some
|
|
environments, such as when prelink(1) is being used. As a result of building
|
|
a directed dependency graph designed for the specific problem domain provided
|
|
by the user, more accurate dependencies can be determined. pkg-config, on the
|
|
other hand builds a database of all known pkg-config files on the system before
|
|
attempting to resolve dependencies, which is a considerably slower and less
|
|
efficient design.
|
|
|
|
pkgconf also does not provide support for pointlessly stupid features implemented
|
|
in pkg-config. If you think a feature is not dumb, then you should file an
|
|
'Improvement' task on Atheme's JIRA instance at <http://jira.atheme.org>.
|
|
|
|
3. Compiling.
|
|
|
|
pkgconf is basically compiled the same way any other Atheme project is compiled:
|
|
|
|
$ ./configure
|
|
$ make
|
|
$ sudo make install
|
|
|
|
