安装 vortex 时出现 libhwloc.so.5 错误

Question

安装所有依赖项后在 vortex 中尝试“make”时，出现以下错误：

    /usr/bin/ld: warning: libhwloc.so.5, needed by /opt/pocl/runtime/lib/libOpenCL.so, not found (try using -rpath or -rpath-link)
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_topology_load'
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_get_api_version'
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_get_nbobjs_by_depth'
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_topology_destroy'
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_bitmap_isequal'
    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_topology_ignore_type'

    /usr/bin/ld: /opt/pocl/runtime/lib/libOpenCL.so: undefined reference to `hwloc_topology_init'
    collect2: error: ld returned 1 exit status

我尝试安装 hwloc 库（v1.10）并为其设置库路径，但是，我仍然遇到以下错误：

    `/opt/pocl/compiler/bin/poclcc: error while loading shared libraries: libhwloc.so.5: cannot open shared object file: No such file or directory
    make[3]: *** [../common.mk:76: kernel.pocl] Error 127
    make[2]: *** [Makefile:2: all] Error 2
    make[1]: *** [Makefile:11: opencl] Error 2
    make: *** [Makefile:7: all] Error 2`

Answer 1

我遇到了同样的问题，我尝试安装hwloc v2.40并手动创建一个可以解决链接问题的链接，但提出了新问题，如下所示：

/usr/bin/ld：/opt/pocl/runtime/lib/libOpenCL.so：从 v0.9.3 开始支持对

hwloc_topology_ignore_type'. But 

hwloc_topology_ignore_type' 的未定义引用。我不确定它是否被删除了。只是分享信息。现在没有解决办法。
