Hi3516DV300晶片報錯“ undefined reference to ×”

我在使用海思硬體接口的時候，用到了mpi庫，然後Makefile裡面連結了這個庫，但是編譯到了連結的時候報錯了：

　　這些信号相關的函數連結pthread庫，HI_*相關的接口去文檔查屬于哪個庫，或許我的檔案跟目前開發闆不比對，我連續找了三個沒找到，不過這麼火的晶片别人肯定也用過，是以方案一直接上網搜該函數；方案二我有一份上司給的頭檔案和庫檔案，我到整個頭檔案裡面能找到相應的函數，然後就去把名字差不多的庫檔案連結進去，果然編譯通過了。還有要特别注意的是基礎庫要靠右側。最後，strncpy_s等幾個函數海思有自己的實作，在庫libsecurec.so（或靜态庫libsecurec.a）裡面，這個基礎庫要靠右側放。

附上自己的Makefile吧，省得下次忘記了

CC       = arm-himix200-linux-gcc
CCFLAGS   = -Wall -O -g

INCLUDE  = -I ./include 
# 可執行檔案的名字

LIBPATH  = -L ./lib/
LIBNAME   =  -lmpi -live -lupvqe -ldnvqe  -lVoiceEngine -lpthread  -lsecurec


#正規表達式表示目錄下所有.c檔案，
C_SRCS= $(wildcard ./src/*.c)

# 第一行依賴關系：冒号後面為依賴的檔案
# 第二行規則：$@表示目标檔案，$^表示所有依賴檔案，$<表示第一個依賴檔案
$(TARGET): $(C_SRCS)    
  $(CC)   $(CCFLAGS) $(INCLUDE)  $(LIBPATH) $(LIBNAME)  -o ./build/$@  $^


# make clean删除所有.o和目标檔案
