正确的编译命令代码:
g++ c_mysql.cpp -L/usr/local/mysql/lib/ -lmysqlclient -lz -lm -o cout
注意:
如果/tmp/ccTGmMS21.o: In function `main':
/tmp/ccTGmMS21.o(.text+0x11): undefined reference to `mysql_init'
那么参数增加-L/usr/lib/mysql -lmysqlclient
如果
usr/lib/mysql/libmysqlclient.a(my_compress.o): In function `my_uncompress':
my_compress.o(.text+0xaa): undefined reference to `uncompress'
那么增加-lz参数
规范点: g++ c_mysql.cpp -L/usr/local/mysql/lib/ -lmysqlclient -lz -lm
