Missing fbv.tcz FrameBuffer on piCore

[Rabie]

Hi There,

Missing the extension fbv.tcz FrameBuffer on PiCore v13.x/armv7

http://s-tech.elsat.net.pl/fbv/
https://github.com/godspeed1989/fbv

Thx

[vinnie]

Do I remember wrongly or do the arms not have framebuffer support like intel?

[Juanito]

It would be easy to compile fbv yourself and test

[Rabie]

Hi Juanito,

i will try that
Thx

[Rabie]

Hi Juanito,

i downloaded the latest version of fbv "fbv-1.0b.tar.gz" and i am trying to copmile it

so here what i did:

installed all needed extensions (giflib.tcz | giflib-dev.tcz | libjpeg-turbo.tcz | libjpeg-turbo-dev.tcz | libpng-dev.tcz | libpng.tcz)

unpack the archive
./configure

and the it check for the libraries

Code: [Select]

checking for libungif presence... no   (i think this is the problem)
checking for libjpeg presence... yes
checking for libpng presence... yes
building with bmp support... yes
checking for DEFAULT_FRAMEBUFFER... /dev/fb0
installation dir: /usr/local/bin
manuals dir: /usr/local/man

if i continue with "make" anyway, i get an error:

make

Code: [Select]

any Ideas ?

Hi Rabie
If you have errors and need to start over, you should probably start with a clean slate:

Code: [Select]

make clean
./configure --prefix=/usr/local --without-libungif
make

[curaga]

Your fbv version looks to be very old, the png and gif libs have changed since. Look at Debian/Ubuntu repos, they may have patches.

Hi curaga,

i think this is the latest version of fbv

i got some warnings but jpg did work

i think jpeg will do the job for me

Thank you very much

Hi Rich,

i started a new Topic to let fbv start at boot http://forum.tinycorelinux.net/index.php?topic=25171.msg160543#msg160543

you already helped me doing that on CorePure64 v10.x but now i need to do it on PiCore http://forum.tinycorelinux.net/index.php/topic,24622.15.html

Thx

[curaga]

Hi curaga,

i think this is the latest version of fbv
i may be wrong but i think this is the homepage
http://s-tech.elsat.net.pl/fbv/

Look at the date on that page.

[Rich]

Hi Rabie
The second link you posted appears to be much more recent:
https://github.com/godspeed1989/fbv

It includes this note:

GIF support through libungif has been removed as that library is obsolete.

Looking through  main.c  I think this warning should be gone:

Code: [Select]

main.c:431:4: warning: ‘i.do_free’ may be used uninitialized in this function [-Wmaybe - uninitialized]
  431 |  if(i.do_free)
The  jpeg.c  warnings should be gone as well.

Hi Rabie
If this is just for a splash screen while booting, this may be of interest:
