这可能听起来像一个愚蠢的问题.但是这里.....我正在使用一个名为db_access.c的C程序,它与MySQL交互(在Ubuntu 10.10中与MySQL Server版本:5.1.49-1ubuntu8.1(Ubuntu)).在程序中,我有:include "mysql.h" 当我执行以下操作时,一切正常:

gcc -I/usr/include/mysql db_access.c -lmysqlclient -o db_access
./db_access

当我尝试将其集成到现有(和工作的makefile)时出现问题.makefile的内容:

all: MappingServer

#Macro definitions
CC = gcc
CFLAGS = -lm
INCLUDES = -I/usr/include/mysql
LIBS = -L/usr/lib/mysql -lmysqlclient 

MappingServer.o: MappingServer.c map_registration.h 
    $(CC) $(CFLAGS) -c MappingServer.c

route_aggregation.o: route_aggregation.c map_registration.h 
    $(CC) $(CFLAGS) -c route_aggregation.c

db_access.o: db_access.c map_registration.h mysql.h
    $(CC) $(CFLAGS) $(INCLUDES) -c db_access.c 

MappingServer: MappingServer.o route_aggregation.o db_access.o
    $(CC) $(LIBS) -o MappingServer MappingServer.o route_aggregation.o db_access.o  

clean:
    -rm MappingServer.o route_aggregation.o db_access.o

我还有另外两个C程序,MappingServer.c和route_aggregation.c.这三个文件需要一起编译.顺便说一句,我也做了:

root@ahuq-kitchen:/home/ahuq/MappingServer# mysql_config --cflags
-I/usr/include/mysql  -DBIG_JOINS=1  -fno-strict-aliasing   -DUNIV_LINUX -DUNIV_LINUX

和 …
