cross compiling library icu in buildroot and linked on application , applition outputs nothing

Hi guys , 

I encountered a very strange issue while cross compiling library ICU and application with linaro arm toolchian generated from Buildroot . Application works fine without linking ICU , but failed to run and exit immediately with nothing output in console . I tried to debug with

LD_DEBUG=files ./application  

LD_DEBUG=files ./application 347: file=libz.so.1 [0]; needed by ./appliation [0] 347: file=libz.so.1 [0]; generating link map 347: dynamic: 0xb5da7d78 base: 0xb5d93000 size: 0x00014f98 347: entry: 0xb5d94838 phdr: 0xb5d93034 phnum: 6 347: 347: 347: file=libdl.so.2 [0]; needed by ./application [0] 347: file=libdl.so.2 [0]; generating link map 347: dynamic: 0xb5d90ef8 base: 0xb5d87000 size: 0x0000a0b0 347: entry: 0xb5d8793c phdr: 0xb5d87034 phnum: 8 347: 347: 
       347: file=libicudata.so.48 [0]; needed by ./application [0] 

It seems that application found libicudata.so smoothly , but failed to generate link map .

ICU library used to work fine on another platform compiling with codesocery toolchain .
For new project , I downloaded a buildroot-201306 and added linaro-201205 toolchain .

I am wondering is this issue related with linaro toolchain or some bug of library ICU .

If anyone has faced same situation , please give me some suggestion .

Any advice would be great appreciated as well .


Kindly Regards ,

DirectFB application silently crashes when event buffer is used

Hi,

I'm experiencing the following problem when using DirectFB 1.2.8 on an
embedded linux device running kernel 2.6.38 (mipsel).  The device is
equipped with a tslib-compatible touchscreen.  It works fine with
DirectFB and I can see the mouse cursor on the screen and it moves
correctly when the screen is touched.

However, when I create an event buffer to process window events, the
application suddenly crashes when a screen is touched.  This happens
independently on whether or not I was trying to process events from
the buffer.  The weird thing is how it crashes: it simply terminates,
leaving no error message, no core dump, simply nothing.  I've tried
some debug outputs and it seems that the application terminates at
random positions whenever a screen is touched (sometimes it can be
touched few times but it always crashes later on).

Also I've made the following observation.  My application also uses a
serial connection (using libmodbus) and when I disable this serial
line (i.e. not open it) then everything works fine as expected.  I've
tried to separate DirectFB and serial line communication into
different threads and even processes but it did not help.

Does anyone have an idea what might be wrong.  I would be grateful for
any suggestion as I'm becoming a little bit desperate ;-)

Thanks,

Jan

Fusion, One modules, separate input events by apps

Hello directfb-users.
I'm just diving in directfb. Trying it in VirtualBox.
And I must say documentation is pretty poor and unclear.

I think maybe this mailing list can help me to figure out some questions:

1) linux-one and linux-fusion.
    Both of them are IPC mechanisms?
    AFAIK linux-fusion is dbus like system?(ask/register service
communicate with it)
    what is linux-one for?
    Why IPC mechanism is working in kernel space? Why just not to share
some memory?
2)  ilixi compositor and application flags:

Let's say I want to create an environment where I have statusbar like
application and all remaining space to current application. Applications
can replace each other. How to handle input in this apps? My statusbar
must always receive input events. And all other input events must be
translates to only foreground application.

Thank you.

avoid using surface's lock()/unlock()?

Hi,

In projects I'm working with, sometimes we check out the surfaces to access their data directly either to READ or to WRITE and in our blitter, we don't flush the surfaces if they had been checked out for READ only.

In my opinion, if possible I would avoid using lock/unlock() and let DirectFB core decide whether to flush the surfaces or not. This would simplify our code and also avoid problems with synchronizations in multi-threaded applications?

Could someone please comment on this for me?

Thanks!

Using DirectFB build in 32bits on a 64bits linux desktop

Hi,

 

I managed to build DirectFB in 32bits on my 64bit Linux desktop.

But when entering linux Fusion world, I get the following message :

 

(!) Fusion/Init: Could not enter world '1'!

    --> Not a typewriter

Could not initialize DirectFB

 

I tried rebuilding the linux-fusion kernel bodule using the –m32 flag, but got the same message.

When tracing the code, ioctl(fd, ENTER_FUSION, &enter) (fusion.c:725) returns with errno! EINTR

Any idea on wath is going wrong?

 

Regards,

Eric

++DFB: Missing APIs

Hi,

I wonder whether APIs are added to ++DFB on a as-needed basis.  If that's the case, can you add `IDirectFBSurface::SetRenderOptions()` and `IDirectFBWindow::[GS]etApplicationID()`?

Patches attached.

I'd like to use ++DFB in a production environment but I miss these three methods.

Cheers,
Kris

Surface Memory deallocation

Hi ,
 I used DFB 1.6.1 . I create surface using dfb->CreateSurface with DSDESC_PREALLOCATED. When the memory allocated through dfb_surface_buffer_create via CreateSurface is released. I don't see this memory getting released after dfb->release(surface). Please advice. Is there a API to release the memory?

Newer GNU toolchain doesn't compile directFB examples as it should?

Hello,

I've been trying to run directFB on Xilinx boards with Zynq-ARM processor. I've compiled the directFB with directFB-examples with the older Codesourcery compiler (arm-xilinx-linux-gnueabi toolchain; version 2011.09-50 of Xilinx SDK) and examples work flawlessly.

I've wanted to move to the newer compiler since the one I mentioned above is very old. When I compile directFB with newest compiler (2013.02 of Xilinx SDK) examples can't be started and "df_dok" example exits with this message:
