我正在尝试在 Contiki 2.7 上编译 tinygroupdtls ( tindygroupdtls )。目前，我收到链接器错误。

LD        multicast-client-example.sky
multicast-client-example.co: In function `secure_group_creation':
multicast-client-example.c:(.text.secure_group_creation+0x6): undefined reference to `dtls_new_group'

collect2: error: ld returned 1 exit status
make: *** [multicast-client-example.sky] Error 1

rm multicast-client-example.co obj_sky/contiki-sky-main.o

我不确定 tinygroupdtls 文件夹中的源文件是否正在编译，并导致此问题...

以下是我的makefile：

项目生成文件

APPS += erbium


include $(CONTIKI)/Makefile.include

应用程序生成文件 (Makefile.tinygroupdtls)

ifeq ($(WITH_GROUP_RESPONSE), 1)
tinygroupdtls_src = dtls.c crypto.c hmac.c rijndael.c sha2.c ccm.c netq.c dtls_time.c peer.c group.c key_derivation.c
else
tinygroupdtls_src = dtls.c crypto.c hmac.c rijndael.c sha2.c ccm.c netq.c dtls_time.c peer.c group.c
endif

谁能告诉我我在这里做错了什么？

谢谢
