Nios II编译出错：make: *** No rule to make target `e:/nios ', needed by `/cygdrive/e/nios/Debug/system_de

在用Waveshare的OpenEP4CE10的开发板时,用Nios新建工程，设置好工程路径和提供的ptf文件后和C文件后，编译，

出现：

make: *** No rule to make target `/bin/gtf/generated_app.mk.gtf', needed by `/cygdrive/e/FPGA/EP4CE10/nios/Quartus_II_Project/4x4-Keypad/software/test_fxf_keypad_i_syslib/Debug/system_description/../obj/generated_app.mk-t'. Stop.

纠结了老半天，重建了N次，都没发现问题。现在总结下，出现此类问题可能的原因：
1、工程文件夹命名中包含中文与空格；
2、每次重新生成的System
Library文件夹居然不在E盘，而在D盘的Altera程序目录下的Workspace里，于是File -- Switch Workspace，把Workspace路径设置成当前Nokia
5110工程下的Software文件夹目录下，详见：http://bbs.ednchina.com/BLOG_ARTICLE_1855871.HTM

Holy！
新的问题：
