You may also want wayland support when on Linux. This enables support
|

for EFL to trget wayland support for client applications. To do this
|

supply:
|
||||
|
||||
-Dwl=true
|
||||
|
||||
Framebuffer support:
|
||||
|
||||
This requires linux frame-buffer support, headers etc. This supports
|
||||
basic frame-buffers like /dev/fb as well as input via /dev/input for
|
||||
keyboards and mice in a basic way. Enable this with:
|
||||
|
||||
-Dfb=true
|
||||
|
||||
For more modern framebuffer support you may want drm/kms rendering
|
||||
support so enable this. This is what you also want for wayland
|
||||
compositor support in enlightenment as it will want to be able to
|
||||
render to a moder framebuffer tarbet with atomic buffer swapping. To
|
||||
do this provide:
|

-Ddrm=true

You may want to change the install prefix for EFL with:

||||

|
||||
|
||||
The default prefix if not given is "/usr/local". Many people like to
|
||||
use prefixes like /opt/e or /opt/efl or /home/USERNAME/software etc.

|

You may want to enable valgrind support if you plan on doing debugging
|
||||
with EFL or apps built on top of EFL. This requires an install of
|
||||
valgrind first. You can enable this with:
|
||||
|
||||
--enable-valgrind
|
||||
|
||||
You may want to enable xine support in emotion, as this library
|
||||
provides fairly solid support for a lot of codecs and DVD navigation
|
||||
support and more. You can enable it with:
|
||||
|
||||
--enable-xine
|
||||
|
||||
Wayland is also supported fairly solidly in EFL 1.8. It is not
|
||||
required by default due to it being new and not that widely spread.
|
||||
You can enable Wayland support with:
|
||||
|
||||
--enable-wayland \
|
||||
--enable-elput \
|
||||
--enable-drm
|
||||
|
||||
For faster rendering when dithering down to lower-than 24/32bpp, you
|
||||
can try:
|
||||
|
||||
--with-evas-dither-mask=small
|
||||
|
||||
But this will drop quality slightly, using a small 16x16 ordered
|
||||
dither mask rather than the default 128x128. This should save a little
|
||||
memory too in the binary size of Evas.
|
||||
|
||||
There are many other configure options that can be used, but in
|
||||
general it is not a good idea to go enabling or disabling things
|
||||
unless you wish to break things. The defaults are well tested, with
|
||||
the above recommended options also being well tested. Go much further
|
||||
and your mileage may vary wildly. Disabling features is a good way of
|
||||
breaking EFL functionality, so it is not recommended. The defaults
|
||||
breaking EFL functionality, so it is not recommended to mess with
|
||||
these without understanding the implications. The defaults
|
||||
have been carefully considered to provide full functionality so users
|
||||
will not be missing anything.
|
||||
|
||||
|
||||
VALGRIND DEPENDENCY
|
||||
-------------------
|
||||
|
||||
EFL uses the concept of memory pools (mempool) and this will confuse
|
||||
valgrind memcheck tool. By using memory pool, the memory is still
|
||||
owned by EFL, then valgrind won't alert on memory leaks or use of
|
||||
unused memory. EFL will use memcheck.h from valgrind to declare its
|
||||
memory pools to valgrind, producing better debugging results.
|
||||
|
||||
However valgrind is only available to limited platforms, making it
|
||||
hard for us to declare it a mandatory requirement. Based on
|
||||
--with-profile={dev,debug} valgrind will be used if available or will
|
||||
be issued a warning. You can force valgrind with --enable-valgrind, or
|
||||
disable it and the warning with --disable-valgrind.
|
||||
|
||||
EFL does NOT link to valgrind libraries. Then there is NO runtime
|
||||
dependency on valgrind.
|
||||
|
||||
|
||||
BULLET PHYSICS DEPENDENCY
|
||||
-------------------------
|
||||
|
||||
EFL comes with EPhysics (a physics wrapper library) enabled by
|
||||
default. To build it the user must have BulletPhysics engine installed.
|
||||
|
||||
More information about BulletPhysics can be obtained in the upstream project
|
||||
web site at http://bulletphysics.org
|
||||
|
||||
We have received many reports about BulletPhysics installation and distros
|
||||
packages in bad shape, some without even a package. If your distro doesn't
|
||||
ship a BulletPhysics package or you want to build it from source code follow
|
||||
the instructions below:
|
||||
|
||||
**Required Packages:**
|
||||
|
||||
You should have cmake installed. Bullet comes with autotools and cmake build
|
||||
systems, do not use the autotools alternative, it's unstable, bogus and hasn't
|
||||
been maintained for quite some time.
|
||||
|
||||
**Download the tarball from:**
|
||||
|
||||
http://code.google.com/p/bullet/downloads/list
|
||||
|
||||
**NOTE:**
|
||||
|
||||
The current supported version is 2.80 or greater.
|
||||
|
||||
**Compiling and Installing:**
|
||||
|
||||
Uncompress it to (say) ~/bullet and:
|
||||
|
||||
cd ~/bullet/build
|
||||
cmake .. -DBUILD_CPU_DEMOS=OFF -DBUILD_DEMOS=OFF -DBUILD_SHARED_LIBS=ON
|
||||
make
|
||||
sudo make install
|
||||
sudo ldconfig
|
||||
|
||||
**Ubuntu Users:**
|
||||
|
||||
Alternatively Ubuntu users have the option to install the BulletPhysics from
|
||||
our official EFL PPA:
|
||||
|
||||
https://launchpad.net/~efl/+archive/trunk
|
||||
|
||||
|
||||
PROFILES
|
||||
--------
|
||||
|
||||
EFL build is based on "profiles". It will default to "dev" for
|
||||
unreleased software and "release" for official tarballs. One can
|
||||
change it with --with-profile=NAME, where NAME is one of:
|
||||
|
||||
* **dev**: extra checks useful to test software.
|
||||
* **debug**: superset of dev, with debug features and assert().
|
||||
* **release**: optimizations and less checks so it runs faster.
|
||||
|
||||
|
||||
CRYPTOGRAPHY
|
||||
------------
|
||||
|
||||
EFL officially uses "openssl" library to do signature, cipher and related.
|
||||
Alternatively one can use "gnutls" (some distros are strict about licenses
|
||||
and want gnutls instead of openssl) or disable it. One can change it with
|
||||
--with-crypto=NAME, where NAME is one of: "openssl", "gnutls" and "none".
|
||||
EFL officially offers openssl or gnutls as cryptography backends. By
|
||||
default it uses "openssl" to do signature, cipher and related. Alternatively
|
||||
one can use "gnutls" (some distros are strict about licenses and want gnutls
|
||||
instead of openssl) You can switch to gnutls with:
|
||||
|
||||
-Dcrypto=gnutls
