无法建立，因为在食谱sysroot中缺少相关性-yocto

Question

我正在尝试使用Yocto（Rocko）为我的64位Armv8-A构建mxnet 1.6.0。首先，我从https://downloads.apache.org/incubator/mxnet/1.6.0/下载了mxnet。我将下载的tar保留在其中一层的文件文件夹中。并且我已经将该tar文件包含在我的mxnet.bb文件中，如下所示。

mxnet.bb

SUMMARY = "MXNET Package"
SECTION = "libs"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

PN = 'mxnet'
PV = '1.6.0'

DEPENDS = "openblas opencv gtest gperftools"

SRC_URI := " \
    file://apache-mxnet-src-1.6.0-incubating.tar.gz"

SRC_URI[md5sum] = "76802d6b14cd45c27f063b2bba3c9a14"

S := "${WORKDIR}/apache-${PN}-src-${PV}-incubating"

inherit cmake pkgconfig

OECMAKE_GENERATOR = "Unix Makefiles"

EXTRA_OECMAKE += " -DUSE_SSE=OFF \
-DUSE_CUDA=OFF \
-DUSE_OPENCV=ON \
-DUSE_OPENMP=ON \
-DUSE_MKL_IF_AVAILABLE=OFF \
-DUSE_SIGNAL_HANDLER=ON \
-DUSE_LAPACK=OFF"

• 然后我使用bitbake mnxet命令构建了它。我收到以下错误。

错误：

• 我检查了build/tmp/work/aarch64-poky-linux/openblas/0.3.5-r0/image/opt/openblas/lib，发现.so和.a文件。
• 我注意到build/tmp/work/aarch64-poky-linux/mxnet/1.6.0-r0/recipe-sysroot/lib64，没有libopenblas.so或openblas文件夹。
• 我还检查了build/tmp/sysroots-components/aarch64/openblas并发现其中只有sysroot-providers，没有opt/openblas/lib或任何opt或lib文件夹（如上所述，我找不到openblas图像文件夹中的文件）。

因此，问题是，如何在mxnet中将openblas添加到我的食谱sysroot中？这样就不会抛出openblas错误？

ps.s。仅当我的.so文件存在于/ opt / openblas / lib路径中时，才能构建openblas。否则，如果我尝试将.so文件放在/ lib文件夹中，则会抛出Files/directories were installed but not shipped in any package错误。

Answer 1

您可以尝试添加

FILES_${PN} = "${libdir}/libmxnet.so"

到食谱。
