== Intro ==

===========

Read the README file in the parent directory, and the NEWS and TODO files if you

have not already done so. Make the preparations described in that README before

you try to use any of the utilities in this directory.

This directory contains utilities and associated resources for building this

package on Linux. All the utilities are Perl scripts (.pl files) which will

indicate their purpose if run with either of the options -h, --help. They are

also documented below.

Provided you placed the package directory under the directory you want to be

EPOCROOT (as per the build/README file), there is no need to set EPOCROOT to run

any of the scripts. They will set it. If you set EPOCROOT in the environment for

these scripts they will respect your setting. 

There are two sorts of utilities:

* Utilities that you need only run once, to make necessary fixes to the upstream

Raptor configuration or to the PDK 3.0.h epoc32 tree, so that it is possible to

build any of the targets. The one-time utilties may make use of the patch-files

directory. Any file located at ./patch-files/linux/SOME_PATH/SOME.FILE will be

deployed to replace the file $EPOCROOT/SOME_PATH/SOME.FILE 

* General utilities that you can use repeatedly for development work.

You need to run these utilities from this directory.

== One-time utilities ==

========================

* fix_raptor_config.pl:

-----------------------

Patches the Raptor config file

$EPOCROOT/build/sbsv2/raptor/lib/config/gcc.xml so that:

a) the GCC compiler is configured as gcc, not gcc_mingw.

b) the Standard C/C++ Library is configured as the one installed with the

compiler, not the PDK's STLPort implementation of the Standard Library.

c) the compiler complies with the C++0x standard.

* fix_epoc32.pl:

----------------

Patches the epoc32 tree:

a) to workaround ancient bug #1399.

b) to create a valid preinclude header for gcc 4.4

* prep_env.pl:

--------------

A wrapper for all the other fix_???.pl utilities.

== General utilities ==

=======================

* build_raptor.pl:

------------------

Builds Raptor

* clean_raptor.pl:

------------------

Cleans Raptor (by invoking the 'clean' target of the Raptor build).

* deepclean_raptor.pl:

----------------------

Deletes all files created by building Raptor (which clean_raptor.pl does

not).

* list_targets.pl:

------------------

Lists the targets in the package, with comments on any that don't need to be

built. The targets are listed as component paths relative to $EPOCROOT/build.

* build_target.pl TARGET:

-------------------------

Build the target TARGET, where TARGET is one of the targets listed by

list_targets.pl.

* build_all.pl:

---------------

Build all the targets except Raptor, with Raptor.

* clean_target.pl TARGET:

-------------------------

Clean the target TARGET, where TARGET is one of the targets listed by

list_targets.pl

* clean_all.pl:

---------------

Clean all the targets except Raptor, with Raptor.

* reallyclean_target.pl TARGET:

-------------------------------

Really-cleans target TARGET, where TARGET is one of the targets listed by

list_targets.pl.

* reallyclean_all.pl:

---------------

Really-clean all the targets except Raptor, with Raptor.

* clean_build_logs.pl:

----------------------

Deletes all Raptor build logs from $EPOCROOT/epoc32/build.

* weed_backups.pl:

-----------------

Deletes all files in the package dir that end with '~'.

* get_upstream.pl CLONEDIR:

---------------------------

Clones or updates the upstream package at the baseline revision found in

../baseline.txt, from http://developer.symbian.org/oss/MCL/sftools/dev/build.

The upstream package will be cloned into the existing directory CLONEDIR if

this does not appear to have been already done. Otherwise CLONEDIR/build will

be updated.

* diff_upstream.pl:

-------------------

Diffs this package with upstream package at the baseline revision found in

../baseline.txt.

Options:

-d, --diff-file FILE:    The diffs will be written to FILE.

Default ./patch-files/diff/patch-N.patch, where N is the baseline revision.

-b, --baseline-dir DIR:  The upstream baseline will be cloned into DIR if this

the baseline revision before diffing.

It is assumed that the command 'diff' will invoke the diff tool.

* patch_upstream.pl

-------------------

package that had that upstream baseline.

Options:

-p, --patch-file FILE:   Apply the patch file FILE.

Default ./patch-files/diffs/patch-N.patch, where N is the baseline revision

-b, --baseline-dir DIR:  The upstream baseline will be cloned into DIR if this

the baseline revision before patching.

It is assumed that the command 'patch' will invoke the patch tool.

== Getting started ==

=====================

To start your development cycle with this package:

* Run build_raptor.pl. This takes some time.

* Run prev_env.pl

* Run build_all.pl. This takes some time.

* If anything has gone wrong, try fixing it.

* Otherwise, pick something to do from the TODO file.
