标题: 编译libdisplay_gfx.z.so，该库依赖闭源库xxx.so，但是libdisplay_gfx.z.so的NEEDED字段包含了xxx.so的路径信息，该如何配置gn脚本把这个路径信息去掉？ [打印本页]

如题，readelf -d libdisplay_gfx.z.so，期望的结果是

(NEEDED) 共享库：[xxx.so]

但是实际结果是：

(NEEDED) 共享库：[obj/device/soc/xxx/xxxx/hardware/xxxx/lib64/xxx.so]

使用的是4.1-release版本

正常链接动态库带路径和rpath是正常的，如果想不带路径，需要重新编译被依赖的共享库，指定该共享库的library，不存在library name。

我直接用ldflags来指定依赖的共享库就没问题了
ohos_shared_library("libdisplay_buffer_vdi_impl") {
  sources = [
   "src/display_gralloc/display_buffer_vdi_impl.cpp",
   "src/display_gralloc/display_gralloc_gbm.cpp"
  ]

  include_dirs = [
"./src/display_gralloc",
"//drivers/peripheral/base",
"//drivers/interface/display/composer/hdifd_parcelable",
"//drivers/interface/display/buffer",
"//drivers/peripheral/display/utils/include",
"//drivers/peripheral/display/buffer/hdi_service/include",
  ]

  output_name = "libdisplay_buffer_vdi_impl"
  cflags = ["-Wno-macro-redefined"]
  #deps = [ "//device/soc/xxxx/xxxx/hardware/xxx:libxxx" ] #原来写法
  ldflags = [ "-L../../device/soc/xxx/edge10/hardware/xxx/lib64", "-lxxx" ] #修改后写法

  external_deps = [
"c_utils:utils",
"drivers_interface_display:display_buffer_idl_headers",
"drivers_interface_display:display_composer_idl_headers",
"hdf_core:libhdf_utils",
"hilog:libhilog",
"ipc:ipc_single",
  ]

  install_enable = true
  install_images = [ chipset_base_dir ]
  subsystem_name = "xxxx"
  part_name = "xxx"
}
