TDA2PXEVM: Using CMake with gcc 4.9

Part Number: TDA2PXEVM
Other Parts Discussed in Thread: SYSBIOS

Hi,

I am trying to initialize CMAKE to work with gcc 4.9 for the TI-RTOS with the VSDK.

I created a CMAKE configuration file and run the CMAKE to configure everything. In my code pthread library is a must so CMAKE is looking for it but fails as follows:

cmake .. -DCMAKE_BUILD_TYPE=Release ... -DCMAKE_TOOLCHAIN_FILE="../build_tools/cmake/arm32-toolchain.cmake"

It seems that the compiler does not support pthread: "-- Check if compiler accepts -pthread - no"

The compiler I am version is as follows, as you can see it says --disable-threads:

gcc-arm-none-eabi-4_9-2015q3/bin/arm-none-eabi-gcc -v

When I search for pthread in both the GCC and the SDK I cannot find any libraries or shared object though I do find a source code

CMAKE version used: 3.16.3

How can I solve this issue?

Is this the wrong compiler that I am using?

Thanks.

    Hi,

    Why don't you use the gmake or make build configuration instead of cmake?

    Thanks

    Hi Gaviraju,

    Thanks for the suggestion, however we do not have the make files, CMAKE creates them after I configure it.

    Thanks.

    Hi,

    For SYSBIOS RTOS the pthread support is given by XDC bios-tools.

    PROCESSOR_SDK_VISION_xx_xx_00_00\ti_components\os_tools\bios_x_xx_xx_00\packages\ti\sysbios\posix\pthread.h

    C:\PROCESSOR_SDK_VISION_xx_xx_00_00\ti_components\os_tools\bios_x_xx_xx_00\packages\ti\sysbios\posix\pthread.c

    Add the below changes in .cfg file to support posix pthread support in RTOS. (ex: vision_sdk/links_fw/src/rtos/bios_app_common/tda2xx/a15_0/a15_0.cfg)

    var Settings = xdc.useModule('ti.sysbios.posix.Settings');
    Settings.supportsMutexPriority = true;

     

     


    Thanks

    Gaviraju

    Hi Gaviraju,

    Thanks for the answer.

    I have done the changes in the configuration file as you indicated.

    CMAKE does not compile the "pthread.c" code it only searches for the pthread library.

    How do I "tell" the SDK to build the pthread library? I think that I need to run a configuration utility that will use the new configuration file and build the pthread library. I search the Internet but could not find how to do this.

    Thanks.

    Hi,

    The TI SYS-BIOS  RTOS compiler do not have pthread library support.

    In order use pthread API in our code we are adding the below changes in the .cfg files.

    var Settings = xdc.useModule('ti.sysbios.posix.Settings');
    Settings.supportsMutexPriority = true;

     


    After adding the above changes we are running the below commands to build the pthread.c source file as a part of RTOS binary.

    cd $INSTALL_DIR/vision_sdk/build

    gmake -s -j

    Sample build log:

    Thanks

    Hi Gaviraju,

    thanks for the answer.

    in addition to what you wrote above i need to change the location of the compiler to match what I have on my machine; this was done in the file~/PROCESSOR_SDK_VISION_03_08_00_00/vision_sdk/build/tools_path.mk

    after doing the change (and using make instead of gmake) the build process started.

    how ever I have a lot of build errors (the following are a sample):

    algorithmLink_cfg.c", line 79: fatal error: cannot open source file "system_cfg.h"
    1 catastrophic error detected in the compilation of "algorithmLink_cfg.c".
    Compilation terminated.

    "system_initDeinitLinks.c", line 130: fatal error: cannot open source file "linksInclude_c66xdsp_2.h"
    1 catastrophic error detected in the compilation of "system_initDeinitLinks.c".
    Compilation terminated.

    And so on. should I change something more?

    Thanks,

    Hi,

    We no need to change the file "tools_path.mk" . Please refer the user-guide to build the vision SDK code.

    File: vision_sdk/docs/UserGuides/

    Thanks
