[EMAIL PROTECTED] requirements What does Edje require?
+
+Edje requires fairly little on your system. to use the edje runtime library
+you need:
+
+ - Evas (library)
+ - Ecore (library)
+ - Eet (library)
+
+To fully build Edje and run the edje builder (edje_cc) you also need:
+
+ - Imlib2 (library)
+
+Evas needs to be build with the PNG and EET image loades enabled at a
+minimum. Edje uses X for the test program, so you will need the SOFTWARE_X11
+engine built into Evas as well. A suggested configure list is below in the
+"cheat sheet" for Evas.
+
+Ecore needs the ECORE, ECORE_EVAS and ECORE_X modules built at a minimum.
+It's suggested to build all the Ecore modules, but the ECORE_FB modules is
+definitely optional.
+
+Eet has no options so just build and install it.
+
+Imlib2 has options, but it will probably select the right ones when you build
+and install it. You really want as many image loaders enabled as you can
+manage. It's suggested at a minumum to have the PNG and JPEG loaders, but
+include whatever loaders correspond to the image formats you want supported
+for loading up and including into an Edje compiled file.
+
+It is suggested right now that you get the latest CVS versions of the
+required libraries. You also need to build them in the right order and make
+sure the right options are enabled in the requiremed libraries. Here is a
+quick "cheat sheet" on how to get started.
+
[EMAIL PROTECTED]
+1. You need Eet from the HEAD cvs branch (must be up-to-date)
+
+ cvs co e17/libs/eet
+ cd e17/libs/eet
+ ./autogen.sh
+ ./configure
+ make
+ sudo make install
+ cd
+
+2. You need Evas from the HEAD branch built with eet loader support.
+
+ cvs co e17/libs/evas
+ cd e17/libs/evas
+ ./autogen.sh
+ ./configure \
+ --enable-software-x11 \
+ --enable-image-loader-png \
+ --enable-image-loader-jpeg \
+ --enable-image-loader-eet \
+ --enable-cpu-c \
+ --enable-cpu-mmx \
+ --enable-cpu-p2-only \
+ --enable-scale-smooth \
+ --enable-scale-sample \
+ --enable-convert-8-rgb-332 \
+ --enable-convert-8-rgb-666 \
+ --enable-convert-8-rgb-232 \
+ --enable-convert-8-rgb-222 \
+ --enable-convert-8-rgb-221 \
+ --enable-convert-8-rgb-121 \
+ --enable-convert-8-rgb-111 \
+ --enable-convert-16-rgb-565 \
+ --enable-convert-16-rgb-555 \
+ --enable-convert-16-rgb-rot-0 \
+ --enable-convert-16-rgb-rot-90 \
+ --enable-convert-16-rgb-rot-270 \
+ --enable-convert-32-rgb-8888 \
+ --enable-convert-32-rgbx-8888 \
+ --enable-convert-32-bgr-8888 \
+ --enable-convert-32-bgrx-8888 \
+ --enable-convert-32-rgb-rot-0 \
+ --enable-convert-32-rgb-rot-90 \
+ --enable-convert-32-rgb-rot-270
+ make
+ sudo make install
+ cd
+
+3. You need Ecore from the SPLIT cvs branch
+
+ cvs co -r SPLIT e17/libs/ecore
+ cd e17/libs/ecore
+ ./autogen.sh
+ ./configure \
+ --enable-ecore-x \
+ --enable-ecore-evas \
+ --enable-ecore-job \
+ --enable-ecore-con \
+ --enable-ecore-ipc
+ make
+ sudo make install
+ cd
+
+4. You need Imlib2 installed. any release from 1.0.0 and up will do.

[EMAIL PROTECTED] compiling How to compile and test Edje
+
+Now you need to compile and install edje.
+
[EMAIL PROTECTED]
+ ./configure
+ make
+ sudo make install
[EMAIL PROTECTED]
+
+You now have it installed and ready to go, but you are missing data files. In
+data/ there are data sets for you to look at as examples. To try one out do:
+
[EMAIL PROTECTED]
+ cd data
+ ./e_logo.sh
+
+ edje ./e_logo.eet test
[EMAIL PROTECTED]
+
+The edje test program/viewer is able to view multiple edje data sets. The
+following will view 3 of them at once in the one window (which you can resize
+to give you more space to move and resize the edje data sets around):
+

+ edje ./e_logo.eet test ./e_logo.eet test ./e_logo.eet test

[EMAIL PROTECTED] details So how does this all work?
+
+Edje inernally holds a geometry state machine and state graph of what is
+visible, not, where, at what size, with what colours etc. This is described
+to Edje from an Edje .eet file containing this information. These files can
+be produced by using edje_cc to take a text file (a .edc file) and "compile"
+an aoutput .eet file that contains this information, images and any other
+data needed.
