unresolved symbols in enigma plugins

[MastaG]

Hi there,

I'm struggling a bit building a Enigma tuxbox squashfs image for dbox2.
My aim is to use the 2.6 kernel and gcc 4.7 build options.
It works fine, however the included plugins: script, ngrab and movieplayer do not work.
They all fail with _ZN7* and _ZN8* symbols missing.


I've configured with:

Code: Alles auswählen

./configure --prefix=$DISTDIR --with-gcc47 --with-boxtype=dbox2 --enable-kernel26 \
--enable-fbclear --disable-tuxmail --disable-tuxcom --enable-eraseall --enable-fx2-outdoor \

flash-enigma-squashfs-all

mklibs seems to strip too many symbols from libcurl libungif etc...
They are present in cdkroot/lib, but they're missing from cdkflash/root-enigma-squashfs/lib

Possible reasons?
- I've disabled a few things like: ext3, tuxcom, tuxmail, rss
- mklibs is bugged
- gcc4.7 uses LTO which may break mklibs?

I tried:
- Forcing python2 for mklibs instead of python3
- Both old and current version of libburl

No Luck yet.
Anyone tried to build an enigma image for dbox2 recently?
I'd like to try the movieplayer

[MastaG]

I think I've found the reason why the required symbols for enigma plugins get stripped.
The mklibs command in the Makefile does not scan all directories.

Code: Alles auswählen

	$(MKLIBS) --target $(target) --libc-extras-dir \
		$(targetprefix)/lib/libc_pic \
		-d $</lib \
		-D -L $(mklibs_librarypath) \
		--root $< \
		`find $</bin/ -path "*bin/?*" -type f` \
		`find $</var/bin/ -path "*bin/?*" -type f` \
		`find $</lib/ -name "libnss_*" -type f` \
		`find $</lib/ -name "libsqlite3*" -type f` \
		`find $</lib/ -name "*.so" -type f` \
		`find $</sbin/ -path "*sbin/?*" -type f`

At the stage where mkibs is executed, not all plugins are present in /lib, for example libfx.so is there so the "outdoor" eyecandy plugin works.
However a few other plugins are in other directories (I have to check which ones since I restarted a fresh build).

I'll report back (hopefully with a patch).

[MastaG]

Found the problem!

cdkflash/root/lib/tuxbox/plugins contains:
outdoor.la
outdoor.so
tuxtxt.la
tuxtxt.so

cdkflash/root-enigma-squashfs/lib/tuxbox/plugins contains:
dbswitch.so
movieplayer.so
ngrabstart.so
ngrabstop.so
outdoor.la
outdoor.so
script.so
tuxtxt.la
tuxtxt.so

So it seems only the symbols for tuxtxt and outdoor plugins are being kept since those modules are present in the cdkflash/root directory.
The other plugins get copied to cdkflash/root-enigma-squashfs at another stage so they're not checked for symbols.

I've checked the Makefile but I cannot see how the buildsystem decides which files to choose for each root.

Any ideas?

[MastaG]

Okay I give up,

could really need some help.
I'm using unmodified source for everything.
Nokia Dbox-2 Enigma, gcc4.7 and kernel 2.6.

When I try to launch some plugins:

Code: Alles auswählen

I've tried to explicitly include the plugins path with mklibs:

However still the same missing symbols.

Secondly I tried to use the un-stripped versions of the plugins by adding these lines to root-enigma-squashfs.sh:

Code: Alles auswählen

rm -vf $1/root-enigma-squashfs/lib/tuxbox/plugins/script.so
rm -vf $1/root-enigma-squashfs/lib/tuxbox/plugins/dbswitch.so
rm -vf $1/root-enigma-squashfs/lib/tuxbox/plugins/movieplayer.so
rm -vf $1/root-enigma-squashfs/lib/tuxbox/plugins/ngrabstart.so
rm -vf $1/root-enigma-squashfs/lib/tuxbox/plugins/ngrabstop.so
cp -vf /home/mastag/dbox2/apps/tuxbox/plugins/enigma/script/.libs/script.so.0.0.0 $1/root-enigma-squashfs/lib/tuxbox/plugins/script.so
cp -vf /home/mastag/dbox2/apps/tuxbox/plugins/enigma/movieplayer/.libs/movieplayer.so.0.0.0 $1/root-enigma-squashfs/lib/tuxbox/plugins/movieplayer.so
cp -vf /home/mastag/dbox2/apps/tuxbox/plugins/enigma/ngrabstart/.libs/ngrabstart.so.0.0.0 $1/root-enigma-squashfs/lib/tuxbox/plugins/ngrabstart.so
cp -vf /home/mastag/dbox2/apps/tuxbox/plugins/enigma/ngrabstop/.libs/ngrabstop.so.0.0.0 $1/root-enigma-squashfs/lib/tuxbox/plugins/ngrabstop.so
cp -vf /home/mastag/dbox2/apps/tuxbox/plugins/enigma/dbswitch/.libs/dbswitch.so.0.0.0 $1/root-enigma-squashfs/lib/tuxbox/plugins/dbswitch.so

So after mklibs, but BEFORE it creates the root-enigma-squashfs.img, it replaces the plugins with their un-stripped versions.

Still the same missing symbols

I know enigma isn't very popular compared neutrino.
But can anyone please tell me where these symbols should be declared?

EDIT:

I think the symbols are being stripped from: cdkflash/root-enigma-squashfs/bin/enigma binary am I correct.
Since the plugins are run by enigma itself, maybe enigma should supply the functions.
Because I can see the symbols being present in the un-stripped enigma binary.

[GetAway]

Hi,

try to contact rhabarber1848. He has found a lot bugs in sourcecode related to gcc47.
Maybe that some variables not initialized so they will be stripped. I remember, that was
the problem in some drivers.

[MastaG]

GetAway you're absolutely right.
mklibs is not to blame.

I tried using the untouched and un-stripped enigma binary from the source directory with the un-stripped plugins as well.
And I get the same missing symbols.

Those symbols should be declared within the enigma binary.
And I think they're present since grepping those symbols in the enigma binary will match all of them.
However they're not exported when doing "powerpc-unknown-linux-gnu-objdump -T enigma", so it looks like a compiler issue.
I think the source needs some cleaning/refactoring for gcc 4.7.


I also tried the gcc 4.1.2 (gcc4 options) but that will build a broken image.
It's stuck on some green screen, probably related to drivers.


Finally I tried the original gcc 3.4.6 compiler and it builds a working image.
All addons are working! (movieplayer FTW).
The only downside of gcc 3.4.6 is that it generates much larger binaries compared to gcc 4.7.

I only have one problem still.
It may be offtopic, so if it's not related to the buildsystem, then I'll open a new topic.
My receiver is unable to scan for channels with the enigma image I built (kernel 2.6 and gcc 3.4.6).

I've tried my image on two Nokia 2x DVB-C receivers using Avia500 v110 firmware and the builtin v0014 ucode.
It will succesfully "LOCK" on the transponder, but scanning will find nothing.
I've tried another image (by another team) based on kernel 2.4, and both receivers will find channels when running this image.

Anyone knows about this problem?
Could be driver related?

EDIT: Here is the dmesg output during scan.

It scans 30 transponders and each of them will LOCK when mnually scanning, however it finds nothing.
After 5 seconds it will skip to the next transponder.

Any ideas?

I'm not totally sure, but I think you need a cam-alpha.bin, even for uncrypted channels.

Oh my god, you're totally right! Thanks alot!
All these forums were mentioning the cam-alpha.bin firmware was only required for using certain smartcards.
Never knew it was also necessary for using the tuner.

I have a 100% working Enigma image for dbox2 now running on linux 2.6.

So what have we learned from all this?

Compiler:
Gcc 4.7 creates much smaller and better optimized code (probably due to LTO).
Enigma is also more stable and less prone to freezes or sudden reboots when opening and closing the gui (e.g. channellist).
Also Enigma feels a bit faster when compiled with gcc 4.7 (could be due to the binaries being smaller).
However some symbols required for running certain tuxbox plugins like movieplayer and ngrab are not exposed by the enigma binary.
So these plugins will not run, this could be related to LTO or messy code.

Gcc 3.4.6 is the opposite of 4.7.
It created bigger binaries and it's less stable.
However, it does export all symbols so you can run all external plugins.

I guess if you can live without external plugins, gcc 4.7 is definitely for the win.
I'm running a dedicated low-power computer for in-house streaming, and I've also setup VLC for the dbox2 movieplayer.
So I'm sticking with gcc 3.4.6 for now.


I have a few questions left.

1. I want to play with the Enigma source (trying to fix the gcc 4.7 issues).
How can I only rebuild only Enigma and the tuxbox related apps and plugins?
Is there any Makefile target for doing that? eg Make enigma

2. Is it possible to make the dbox2 read my local cable card?
It's Irdeto2 and it runs at 6MHz, I'm now sharing it, but I'd like to stick it inside my dbox2 so it also works without network access.

3. How can I enable hardware section filtering in the kernel 2.6 drivers.
I UN-checked "Disable hardware section filtering" in the Expert settings and I'm using the builtin 0014 ucode.
However during booting I still have:
