Subject: [PATCH 2/2] Add Libs.private field to libnftnl.pc
|
|
|
|
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:
|
|
|
|
Libs.private:
|
|
|
|
This line should list any private libraries in use. Private
|
|
libraries are libraries which are not exposed through your
|
|
library, but are needed in the case of static linking.
|
|
|
|
Therefore, this patch adds a reference to libmnl in the Libs.private
|
|
field of libnftnl pkg-config file.
