Yocto：没有可用的食谱（完整）

Question

I'm attempting to create an image with

bitbake core-image-minimal

For my jetson nano (nvidia tegra). I've added the meta-layer for tegra devices from https://github.com/madisongh/meta-tegra and added it to bblayer.conf. I have also added lines

IMAGE_CLASSES += "image_types_tegra"               
IMAGE_FSTYPES = "tegraflash"

to the local.conf file to be able to flash it later.

When I attempt to run the bitbake command to create the image, I get the error message:

ERROR: No recipes available for:
/home/mci/yocto/jetson-nano/meta-tegra/recipes-graphics/vulkan/vulkan-loader_1.1.%.bbappend
/home/mci/yocto/jetson-nano/meta-tegra/recipes-graphics/vulkan/vulkan-tools_1.1.%.bbappend
/home/mci/yocto/jetson-nano/meta-tegra/recipes-graphics/wayland/weston_7.0.0.bbappend

But aren't the files it says there is no recipes for the same recipes it's looking for? Isn't "vulkan-loader_1.1.%.bbappend" a recipe?

How do I solve this problem? Is it because it can't find the files or is the bbappend not the recipes but something else?

Answer 1

我删除了所有内容，然后重新开始构建，执行完全相同的过程，并将所有相同的行添加到local.conf和bblayer.conf ...但是这次，bitbake命令运行完全没有错误。

Answer 2

Michael,

I don't have an answer for the vulkan pieces but I do have a few pointers since we seem to be going down a similar path with the nano.

1. Use the warrior branch of yocto
2. You'll need to download the binary pieces of the nvidia sdk through the SDK manager
3. Point to these sdk packages in your local.conf with the NVIDIA_DEVNET_MIRROR variable. ex: "file:///home/nvidia/yocto/git/poky/devnet/nano-dev"
4. Because of the binary pieces in step 2, you need to use an older gcc version which isn't really supported in warrior. I used the linaro-7.2 layer.
5. Since gcc7 is not supported in warrior, yocto / openembedded will attempt to pass flags to gcc which will make the build fail. Here's a summary, which I hope is complete, to help you through this.

Add DEBUG_PREFIX_MAP="" to local.conf and apply the following patch.

Best of luck! I apologize if this is a bit rough, but I'm just getting through this myself.
