Hi3516DV300芯片報錯“ undefined reference to ×”

 

 

我在使用海思硬件接口的時候，用到了mpi庫，然后Makefile里面鏈接了這個庫，但是編譯到了鏈接的時候報錯了：

./lib//libmpi.so: undefined reference to `sem_post'

　　這些信號相關的函數鏈接pthread庫，HI_*相關的接口去文檔查屬於哪個庫，或許我的文檔跟當前開發板不匹配，我連續找了三個沒找到，不過這么火的芯片別人肯定也用過，所以方案一直接上網搜該函數；方案二我有一份領導給的頭文件和庫文件，我到整個頭文件里面能找到相應的函數，然后就去把名字差不多的庫文件鏈接進去，果然編譯通過了。還有要特別注意的是基礎庫要靠右側。最后，strncpy_s等幾個函數海思有自己的實現，在庫libsecurec.so（或靜態庫libsecurec.a）里面，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 
# 可執行文件的名字
TARGET   = encJpeg


# 鏈接 libmpi.a等庫文件
LIBPATH  = -L ./lib/
LIBNAME   =  -lmpi -live -lupvqe -ldnvqe  -lVoiceEngine -lpthread  -lsecurec


#正則表達式表示目錄下所有.c文件，
C_SRCS= $(wildcard ./src/*.c)

# 第一行依賴關系：冒號后面為依賴的文件
# 第二行規則：$@表示目標文件，$^表示所有依賴文件，$<表示第一個依賴文件
$(TARGET): $(C_SRCS)		
	$(CC)   $(CCFLAGS) $(INCLUDE)  $(LIBPATH) $(LIBNAME)  -o ./build/$@  $^


# make clean刪除所有.o和目標文件
clean:
	rm -f ./build/*
