283 f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	42 dnl eCos is a componentized architecture for deeply embedded systems.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	43 dnl It requires a very different configuration system from typical
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	44 dnl autoconfiscated software such as the various GNU packages.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	45 dnl
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	46 dnl The main eCos host-side software is autoconfiscated to some extent,
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	47 dnl in that the usual sequence of "configure;make;make install" will
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	48 dnl work under the right conditions. However it does not conform to
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	49 dnl the GNU coding standards in numerous ways, for example "make dist"
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	50 dnl will not work. The main eCos host-side software lives in the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	51 dnl "host" subdirectory, and is built unconditionally.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	52 dnl
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	53 dnl The eCos target-side software lives in the "packages" subdirectory,
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	54 dnl and is organized in numerous subdirectories corresponding to different
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	55 dnl packages and potentially different versions of each package. In the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	56 dnl master repository managed by CVS there will only be one version of
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	57 dnl each package, "current", which simplifies things somewhat. Other
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	58 dnl repositories will not be quite so straightforward and require a
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	59 dnl suitable administration tool.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	60 dnl
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	61 dnl The various eCos packages are not currently auto-confiscated.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	62 dnl In particular building eCos requires the use of eCos configuration
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	63 dnl technology, not autoconf - there is simply no good way of handling
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	64 dnl a system as highly configurable as eCos using a few command-line
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	65 dnl options passed to "configure". There would also be serious confusion
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	66 dnl between host and target, especially when e.g. cross-compiling the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	67 dnl host tools. However a possible future enhancement
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	68 dnl would involve making eCos releases via configure and make, thus
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	69 dnl allowing for a release process that combines building the various
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	70 dnl host-side tools such as gcc with creating eCos epk's for the various
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	71 dnl packages.
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	72 dnl
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	73 dnl A complication is that some of the eCos target-side packages also
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	74 dnl contain package-specific host-side support. For example the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	75 dnl Linux synthetic target support uses special host-side software
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	76 dnl to provide I/O facilities: the architectural HAL package provdes
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	77 dnl generic support, the synthetic ethernet package extends this
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	78 dnl with ethernet support, and so on. Such package-specific host-side
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	79 dnl software does not belong in the main host subdirectory, that
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	80 dnl would make it very difficult to distribute new packages or
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	81 dnl new versions of a package. However keeping the code with the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	82 dnl various packages makes building more complicated.

283 f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	84 dnl 1) if the entire repository is managed by CVS or anoncvs, this
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	85 dnl configure script will search the packages tree for any packages
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	86 dnl that have host-side software that needs to be built -
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	87 dnl specifically, that have a file "configure" inside a "host"

f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	90 dnl 2) if instead the repository contains additional packages
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	91 dnl installed as epk's and managed by an administration tool then
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	92 dnl it is the responsibility of that tool to let the users build
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	93 dnl and rebuild the host-side software as required, for whichever
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	94 dnl host platform or platforms are being used. In other words
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	95 dnl it is the responsibility of the admin tool to create a
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	96 dnl suitable build directory and run "configure; make; make install",
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	97 dnl usually as part of the installation process. Note that several
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	98 dnl versions of a package may be installed, and it is the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	99 dnl responsibility of each package to take this into account
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	100 dnl (although the configure macros are aware of this to some extent,
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	101 dnl and will e.g. generate suitable install directory names).
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	102 dnl Also note that the top-level configure script will not pick
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	103 dnl up such packages because they will be versioned, i.e. the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	104 dnl test for current/host/configure will fail because the
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	105 dnl version will not be "current".

f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	107 dnl 3) as a special case it may be desirable to ship pre-built binaries
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	108 dnl of some of the package-specific software. It is not clear
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	109 dnl just what would be the best way of shipping these - putting
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	110 dnl them into the epk's would not be quite right because that would
f58bc1b2c2bc Reorganization of the host-side autoconfiscation support, and a couple bartv parents: 208 diff changeset	111 dnl make the epk's host-specific rather than generic.
