CoAP
CoAP 模块编译问题

执行 ``` scons --menuconfig ``` 使能**CoAP** package 3. 保存配置，执行`pkgs --update` 4. 执行`scons` 5. 编译提示如下错误： ``` james@james-Aspire-1602M:~/work/rt-thread/bsp/qemu-vexpress-a9$ scons scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... scons: building associated VariantDir targets: build CC build/packages/coap-latest/coap-rtthread/coap_io_rt.o In file included from packages/coap-latest/libcoap/include/coap/coap_io.h:16:0, from packages/coap-latest/coap-rtthread/coap_io_rt.c:39: packages/coap-latest/libcoap/include/coap/address.h:65:29: error: field 'sin6' has incomplete type struct sockaddr_in6 sin6; ^~~~ packages/coap-latest/libcoap/include/coap/address.h: In function '_coap_address_isany_impl': packages/coap-latest/libcoap/include/coap/address.h:83:20: error: 'in6addr_any' undeclared (first use in this function) return memcmp(&in6addr_any, ^~~~~~~~~~~ packages/coap-latest/libcoap/include/coap/address.h:83:20: note: each undeclared identifier is reported only once for each function it appears in packages/coap-latest/coap-rtthread/coap_io_rt.c: In function 'coap_new_endpoint': packages/coap-latest/coap-rtthread/coap_io_rt.c:154:5: warning: implicit declaration of function 'close' [-Wimplicit-function-declaration] close (sockfd); ^~~~~ packages/coap-latest/coap-rtthread/coap_io_rt.c: At top level: packages/coap-latest/coap-rtthread/coap_io_rt.c:213:19: error: field 'ipi6_addr' has incomplete type struct in6_addr ipi6_addr; /* src/dst IPv6 address */ ^~~~~~~~~ scons: *** [build/packages/coap-latest/coap-rtthread/coap_io_rt.o] Error 1 scons: building terminated because of errors. ``` 信息显示需要使能IPV6协议 但是`scons --menuconfig`后找不到使能IPV6的 地方 在menuconfig里搜索可以看出 NETDEV_IPV6需要设置为1 同时也不知道在哪设置这个参数。 ``` .config - RT-Thread Project Configuration > RT-Thread Components > Network > light weight TCP/IP stack > Search (IPV6) ───────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── ┌────────────────────────────────────────────────────────────────────────────────────────── Search Results ───────────────────────────────────────────────────────────────────────────────────────────┐ │ Symbol: NETDEV_IPV6 [=NETDEV_IPV6] │ │ Type : unknown │ │ │ │ │ │ Symbol: RT_USING_LWIP_IPV6 [=n] │ │ Type : boolean │ │ Prompt: IPV6 protocol │ │ Location: │ │ -> RT-Thread Components │ │ -> Network │ │ -> light weight TCP/IP stack │ │ (1) -> Enable lwIP stack (RT_USING_LWIP [=y]) │ │ Defined at ../../components/net/Kconfig:108 │ │ Depends on: RT_USING_LWIP [=y] && (RT_USING_LWIP210 [=n] || RT_USING_LWIP202 [=y]) && (!RT_USING_NETDEV [=y] || RT_USING_NETDEV [=y] && NETDEV_IPV6) ``` 请大神们帮忙指点一下

将CoAP代码中关于`case AF_INET6: `代码块的地方全部注释。 模块不支持ipv6了 就可以编译通过了。 但少了对ipv6的支持。最好还是配置好rt-thread使他支持 ipv6。

编译链接时出现问题 ： ``` build/packages/coap-latest/libcoap/src/address.o: In function `coap_is_mcast': /home/james/work/rt-thread/bsp/qemu-vexpress-a9/packages/coap-latest/libcoap/src/address.c:47: undefined reference to `IN_MULTICAST' collect2: error: ld returned 1 exit status ``` 不知道为什么 IN_MULTICAST 是这样一个宏定义，为什么出链接问题？ ``` james@james-Aspire-1602M:~/work/rt-thread$ find . -name "*.c" | xargs grep "IN_MULTICAST" ./bsp/qemu-vexpress-a9/packages/coap-latest/libcoap/src/address.c: return IN_MULTICAST(ntohl(a->addr.sin.sin_addr.s_addr));
