Hello all,
first of all let me explain what I am trying to accomplish; my goal at
this moment is to get Enna <http://enna.geexbox.org> up and running on a
mipsel-box (media player box based on a RTD1073 (Realtek) chipset - some
tech info on the CPU
<http://opensource.eminent-online.com/wiki/index.php/EM7080_Tech> ).
(standard firmware/application that runs on these boxes lacks a lot of
'standard' features, that I see present in Enna)
Enna is based on EFL; therefore I am trying to get them running on this
box. I am cross-compiling the libraries using the toolchain provided by
Asus (box with same chipset - mipsel toolchain based on gcc 3.4.4 ).
I also managed to get SDL2 - without GL (no support on this device) -
working on this device (the SDL2 examples work fine and produce nice
output on the TV set). So I am trying to get EFL working with SDL2 (no X
or whatsoever on this device).
My compile order is:
- eina-1.1.0
- eet-1.5.0
- evas_generic_loaders-1.1.0
- evas-1.1.0
- ecore-1.1.0
- e_dbus-1.1.0
- embryo-1.1.0
- edje-1.1.0
- efreet-1.1.0
- ethumb-0.1.1.65643
- expedite-1.1.0
- elementary-0.8.0.65643
Apart from some manual patches I applied (to use the SDL2 headers and API
instead of SDL1.2 or SDL1.3 API), these are the sources available from the
download page.
My standard configure script I use looks like this:
#!/bin/sh
export AR_FLAGS='cru'
export CFLAGS='-pipe -O2 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE
-D_FILE_OFFSET_BITS=64 -msoft-float -mips32
-Wl,-rpath=/usr/local/etc/ketlaer/lib'
export LDFLAGS="-L/usr/local/etc/ketlaer/lib"
export CPPFLAGS="-I/usr/local/etc/ketlaer/include"
export PKG_CONFIG_LIBDIR="/usr/local/etc/ketlaer/lib/pkgconfig/"
./configure --prefix=$KETLAER --host=mipsel-linux
--with-other-options-depending-on-lib
I also (try to) compile the tests and examples from each lib to see how
far I get without any issues. E.g. Apart from eina_hash_06 which
segfaults, all other eina examples work great. But now I am stuck with the
following error (I also did 'export EINA_LOG_LEVELS=eina_module:4' before
running these examples).

================================
This was already a major leap forward since before this I was getting
'File not found' errors from dlopen which were related to some missing
dependencies in other libs. Uninstalled the already compiled libs (EFL),
solved the missing dependencies and started again from scratch with EFL.
But now I am getting the above error.
I then did a 'nm -D' on this module (see below); it seems to me that
'__eina_module_init' exists in this module, but why does eina complain
about not finding this symbol?
Anybody some clues / hints on what to try next to solve this module
loading problem?
Just let me know if you require more info ...
I am hoping I am almost there...
Thanks in advance,
Kind regards,
Erwin Hermans
PS: output of some commands...
