Static linking userspace programs such as nftables against libnftnl
currently doesn't work out of the box, because libnftnl is linked
against libmnl, but this isn't expressed in libnftnl pkg-config
file:
CCLD nft
[...]/bfin-buildroot-uclinux-uclibc/sysroot/usr/lib/libnftnl.a(table.o): In
function `_nft_table_nlmsg_parse':
table.c:(.text+0x480): undefined reference to `_mnl_attr_parse'
table.c:(.text+0x492): undefined reference to `_mnl_attr_get_str'
table.c:(.text+0x4a8): undefined reference to `_mnl_attr_get_u32'
table.c:(.text+0x4ca): undefined reference to `_mnl_attr_get_u32'
[...]
The Libs.private field is specifically designed for such usage:
>From pkg-config documentation:
Requires.private:
A list of packages required by this package. The difference from
Requires is that the packages listed under Requires.private are not
taken into account when a flag list is computed for dynamically
linked executable (i.e., when --static was not specified). In the
situation where each .pc file corresponds to a library,
Requires.private shall be used exclusively to specify the
dependencies between the libraries.
Therefore, this patch adds a reference to libmnl in the Requires.private
field of libnftnl pkg-config file.
