Error when build Enigma2 Image

**lastKnight** · 07.09.2015, 21:08

@betacentauri: You are great !!!
Finally it works.
Now, I suppose I have to put the binary ''enigma2" in usr/bin/ folder of the decoder, is it right ?
And why this is about 22 Mb whereas the original one is only 3 Mb ?

Sorry again, these questions must seem too obvious to you.

You can put it wherever you want. For testing I normally copy it to /tmp, make it executable (chmod 755 /tmp/enigma2), stop original e2 (init 4) and start then the binary (/tmp/enigma2).
But you can also overwrite /usr/bin/enigma2. But then every image update may overwrite it again!

The binary is not stripped(debug symbols are included). That's why it is so big. I can send you tomorrow the command to strip the binary. It's something like that(out of my mind as my PC is not running):
..../<buildenv >/builds/openatv/release/vg2000/tmp/sysroot/i686...linux/usr/bin/mipsel..../mipsel....strip <e2 binary>

Thanks a lot, I really appreciate your support.

This has been a really interesting learning process for me ... Always interested in more detail about builds and although a bit heavy for me, really good info... Think I will still keep to the longer build process ... Easier for me!

The strip command is:
64 bit Linux:
<buildenv>/builds/openatv/release/vg2000/tmp/sysroots/x86_64-linux/usr/bin/mipsel-oe-linux/mipsel-oe-linux-strip <path to e2 binary>

32 bit Linux:
<buildenv>/builds/openatv/release/vg2000/tmp/sysroots/i686-linux/usr/bin/mipsel-oe-linux/mipsel-oe-linux-strip <path to e2 binary>

Well, there are different ways to get a modified e2 binary. The shown one is perfect for me as a developer. I don't want to build a complete image and I don't care about binary size and debug symbols are sometimes useful. I change the code in the local copy of the git, build e2, transfer it to the box and test it. Afterwards I commit or adapt again the code in the git.
If you want a complete image you can create your own git (just create github account, fork openatv e2 git and adapt it) and exchange openatv git url with your git. Then start build and you get your personal image. Or create patches and add them to the enigma2.bb in the buildenv (not in the local copy).

Thanks, maybe I will get round to the 1st option, currently the 2nd option works for me ..... And that was a learning processwith the Git commands!

Thanks a lot.
As regards debugging, is it possible to build enigma2 binary with no optimization ?
II found this line in makefiles : "LDFLAGS = -Wl,-O1 -Wl,--as-needed"
but makefiles seem to be autogenerated.
I would globally change 'O1' into' 'O0', but I don't know ho to do...

CFLAGS include -Os:
"CFLAGS = -Os -pipe -g -feliminate-unused-debug-types -ggdb3 -Wall"

You can change the -Os in the meta-oe-alliance/meta-oe/conf/distro/openatv.conf

LDFLAGS I don't currently know.

**betacentauri** · 08.12.2015, 19:43

It seems you can set LDFLAGS in bb file. E.g. look into meta-oe-alliance/meta-oe/recipes-oe-alliance/openmultiboot/openmultiboot.bb

Code:

EXTRA_OEMAKE = " \
    'CFLAGS=${CFLAGS} \
    -I=${includedir}/freetype2 \
    ${@base_contains("MACHINE_FEATURES", "singlecore", "-DOMB_DEFAULT_TIMER=10" , "-DOMB_DEFAULT_TIMER=5", d)} \
    ${@base_contains("MACHINE_FEATURES", "textlcd", "-DOMB_HAVE_TEXTLCD" , "", d)} \
    ${@base_contains("IMAGE_FSTYPES", "ubi", "-DOMB_FLASH_UBI" , "", d)} \
    ${@base_contains("IMAGE_FSTYPES", "jffs2", "-DOMB_FLASH_JFFS2" , "", d)} \
    ${@base_contains("MACHINE_FEATURES", "dreambox", "-DOMB_DREAMBOX", "", d)} \
    -DOMB_KERNEL_MTD=\"/dev/${MTD_KERNEL}\"' \
    'LDFLAGS= -lfreetype ${LDFLAGS}' \
    "

Perhaps also without EXTRA_OEMAKE like in meta-oe-alliance/meta-brands/meta-vuplus/recipes-frontpannel/vuplus-displayvfd.bb

**lastKnight** · 08.12.2015, 21:19

I added these lines to enigma2.bb file ( the one passed as argument to bitbake):

EXTRA_OEMAKE = " \
'CFLAGS=-O0 -pipe -g -ggdb3 -Wall' \
'LDFLAGS= -O0' \
"
but with no luck.
This is the log.do_compile:
