用LM4F120移植FAT文件系统对SD卡进行操作实验时,当主程序调用f_open()函数时,编译会报错,显示undefined first referenced
symbol in file
--------- ----------------
ff_convert ./ff.obj
ff_wtoupper ./ff.obj
error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "FXP123.out" not built
调用ff.c中的其他函数没问题,如f_close().f_read()等,求解! |
