Build Error

[BloomBabe]

I successfully built project, made petalinux sdk, and sourced its environment-setup file. But when I run build.sh script I got:

Can you check if there's "/usr/lib/gstreamer-1.0/include/gst" under your sysroot? You should follow the steps here up to and including SDK generation to get the sdk.

BTW, what's your petalinux version? 2021.1 release?

[BloomBabe]

I have it in "/usr/lib/x86_64-linux-gnu/gstreamer-1.0/include/gst". Yes, I use 2021.1 release.

Hi @BloomBabe , I think the sysroot should be at $SDKINSTALLPATH/sysroots/cortexa72-cortexa53-xilinx-linux, after you source the file $SDKINSTALLPATH/environment-setup-cortexa72-cortexa53-xilinx-linux, can you confirm? Or can you show the content of your $SDKINSTALLPATH/environment-setup-cortexa72-cortexa53-xilinx-linux?

[BloomBabe]

Content of the environment-setup-cortexa72-cortexa53-xilinx-linux:

# Check for LD_LIBRARY_PATH being set, which can break SDK and generally is a bad practice
# http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html#AEN80
# http://xahlee.info/UnixResource_dir/_/ldpath.html
# Only disable this check if you are absolutely know what you are doing!
if [ ! -z "$LD_LIBRARY_PATH" ]; then
    echo "Your environment is misconfigured, you probably need to 'unset LD_LIBRARY_PATH'"
    echo "but please check why this was set in the first place and that it's safe to unset."
    echo "The SDK will not operate correctly in most cases when LD_LIBRARY_PATH is set."
    echo "For more references see:"

@BloomBabe so you can see the SDKTARGETSYSROOT is /home/schebnev/Petalinux/petalinux-kria-2021.1/image/linux/sdk/sysroots/cortexa72-cortexa53-xilinx-linux If everything goes fine, there should be /home/schebnev/Petalinux/petalinux-kria-2021.1/image/linux/sdk/sysroots/cortexa72-cortexa53-xilinx-linux/usr/include/gstreamer-1.0 Please make sure that you follow the steps here up to and including SDK generation to get the sdk.

[BloomBabe]

I found that in order to connect the gstreamer-1.0 to SDK it is necessary to add it in 'Petalinux Package Groups-->pacakgegroup-petalinux-gstreamer' and then build the project and extract SDK. But I dont understand why this is not mentioned in tutorial

[chkohn]

@BloomBabe if you look at the PetaLinux tutorial here: https://xilinx.github.io/kria-apps-docs/main/build/html/docs/build_petalinux.html#enable-xilinx-application-packages , the step right before the SDK generation enables all the example applications in the PetaLinux BSP which in turn also enables all the dependent packages like gstreamer and others. If you do this prior to SDK generation, you will have everything enabled that is needed to cross-compile this and other example apps. Maybe we should add a note in the SDK generation section https://xilinx.github.io/kria-apps-docs/main/build/html/docs/build_petalinux.html#build-the-sdk as well that mentions to enable these package groups prior to SDK generation, would that help?

[xlnx-yuxiz]

@BloomBabe The "Enable Xilinx Application Packages" section of tutorial is to add the application and all its dependencies into rootfs and also SDK. So if you strictly flow it, there should be gstreamer libs and headers in the SDK.
