我正在尝试在 yocto 构建上编译 Ceres 解算器（适用于英特尔 Aero 无人机）。
我之前尝试使用 git 存储库进行拉取https://ceres-solver.googlesource.com/ceres-solver/但无法获取它。所以我自己下载了 tar.gz 文件，将其上传到我拥有的公共域上并尝试编译。
这是我的 bb 文件现在的样子。

PV = "1.0"
S = "${WORKDIR}/ceres-cmake"
inherit cmake pkgconfig
# Specify any options you want to pass to cmake using EXTRA_OECMAKE:
EXTRA_OECMAKE = ""
现在我看到下载已完成，但在运行 bitbake ceres 命令时，我收到一条错误消息，指出无法找到 CMakelists.txt，而它显然位于 tar.gz 文件中。我查看了其他似乎有效的食谱，并认为 do_unpack 步骤并不是失败的步骤。控制台的输出是：
Loading cache...done.
Loaded 2790 entries from dependency cache.

我做了什么愚蠢或错误的事情吗？
答案1
我不是这方面的专家，但如果你查看文件夹：
/home/thesidjway/rasl_ws/src/intel-aero/poky/build/tmp/work/x86_64-linux/ceres/1.0-r0/ceres-cmake
并检查您的 cmake 文件是否存在于该文件夹中。 Yocto 希望您的 cmake 文件存在于 ceres-cmake 文件夹中。
