Yocto

Question

我正在使用 Yocto 安装 clBLAS 库（https://github.com/clMathLibraries/clBLAS) using the recipe https://github.com/CogentEmbedded/meta-opencl/blob/master/meta-ocl-common/recipes-graphics/clblas/clblas_git.bb

但我每次都会收到以下警告，而且构建的映像中不存在 .so 文件。

WARNING: QA Issue: clblas: Files/directories were installed but not shipped in any package:
  /usr/lib
  /usr/lib/libclBLAS.so.2.12.0
  /usr/lib/libclBLAS.so.2

Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install.
clblas: 14 installed and not shipped files. [installed-vs-shipped]

如何克服此警告并使 .so 文件出现在目标的 /usr/lib 文件夹中？

Answer 1

将以下行添加到您的 clblas_git.bb

 FILES_${PN} += "${libdir}/*"
 FILES_${PN}-dev = "${libdir}/* ${includedir}"

好的解释你会明白的

Answer 2

问题是在构建过程中没有正确考虑 multilib，查看 clBLAS 中的 cmake 文件，它使用 CMake 变量构建 multilib 路径 SUFFIX_LIB and yocto recipe is setting it to be empty here 但是它没有为 multilib 路径编码 yocto 逻辑。一个潜在的修复方法如下
