Summary
Using certain compilers for compilation, there is an alarm message:
ctc E295: ["/home/gaohd/Public/code/dev-system/apps/include/netutils/netlib.h" 1118/45] reference to incomplete enum type
ctc E295: ["/home/gaohd/Public/code/dev-system/apps/include/netutils/netlib.h" 1133/46] reference to incomplete enum type
ctc E295: ["/home/gaohd/Public/code/dev-system/apps/include/netutils/netlib.h" 1151/23] reference to incomplete enum type
ctc E295: ["/home/gaohd/Public/code/dev-system/apps/include/netutils/netlib.h" 1169/23] reference to incomplete enum type
ctc E295: ["/home/gaohd/Public/code/dev-system/apps/include/netutils/netlib.h" 1187/23] reference to incomplete enum type
To address these alarm messages, reference files have been added to the header file.
Impact
Include header files in netlib.h
#ifdef CONFIG_NET_IPTABLES
#include <nuttx/net/netfilter/ip_tables.h>
#include <nuttx/net/netfilter/ip6_tables.h>
#endif
Testing
Compile alarm information cleared, compilation passed, Ethernet communication is normal
