   4 Subject: [PATCH 2/2] Add Libs.private field to libnftnl.pc
   5
   6 Static linking userspace programs such as nftables against libnftnl
   7 currently doesn't work out of the box, because libnftnl is linked
   8 against libmnl, but this isn't expressed in libnftnl pkg-config
   9 file:
  10
  11   CCLD   nft
  12 [...]/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libnftnl.a(table.o): In function `_nft_table_nlmsg_parse':
  13 table.c:(.text+0x480): undefined reference to `_mnl_attr_parse'
  14 table.c:(.text+0x492): undefined reference to `_mnl_attr_get_str'
  15 table.c:(.text+0x4a8): undefined reference to `_mnl_attr_get_u32'
  16 table.c:(.text+0x4ca): undefined reference to `_mnl_attr_get_u32'
  17 [...]
  18
  19 The Libs.private field is specifically designed for such usage:
  20
  21 From pkg-config documentation:
  22
  23   Libs.private:
  24
  25      This line should list any private libraries in use.  Private
  26      libraries are libraries which are not exposed through your
  27      library, but are needed in the case of static linking.
  28
  29 Therefore, this patch adds a reference to libmnl in the Libs.private
  30 field of libnftnl pkg-config file.
