libjpeg and libtiff in sysBios 6?

Other Parts Discussed in Thread: SYSBIOS, AM1808

I've been using both libjpeg and libtiff to read and write jpg and tiff image files in Linux and now I'm thinking about doing a multi-core version of my app.  If I do this exclusively in sysBios, I would need to port these libraries to sysBios.  Obviously I can't do ./configure.  Has anyone attempted this?  Is there an alternative library for reading and writing image files?  Perhaps this a good reason to have one of the cores running Linux.

    What multi-core device are you planning to use for this?

    The C6678 with 8 cores.  I have the app mapped-out to the individual cores and I could put Linux on one of them.  The code development appears simplier if I do everything in sysBios as I could do everything in CCS 5.  If I put Linux on one core how is the software development done?  Would I be forced to build in the MCSDK as I have done previously, use xdc to build the sysBios code for cores 1 to 7, and a make file for core 0?  My concern is that not all debug functions of CCS will work with a non-project debug session.  Non-project debug seems to be an afterthought with TI.

    If the libraries are compiled with CodeGen Tool, it will be able to used by BIOS. As far as the CCS debugging, it does not matter if the code is built using xdc or make file, CCS can be used to debug as long as the code is compiled with global symbols (-g). CCS needs to connect to the core it is debugging and loads the symbols.

    just want to be a bit clearer. The applications on Linux will be using GNU tools to build, whereas applications on BIOS is using CGT tools.

    Hi,

     

    I am working on AM1808 target.

     

    Our Application is running in Qt 4.7. There is image viewer, Which reads all the images. I need to import TIFF images.

     

    But Tiff images are not supporting. I think there is 'libtiff' library is required. How to get this library and solve my issue.

     

    I have gone though the below library link and cross compiled with arm tool chain. But still I am facing issue.
