在用Waveshare的OpenEP4CE10的開發板時,用Nios新建工程，設定好工程路徑和提供的ptf檔案後和C檔案後，編譯，

出現：

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.

糾結了老半天，重建了N次，都沒發現問題。現在總結下，出現此類問題可能的原因：

1、工程資料夾命名中包含中文與空格；

2、每次重新生成的System Library資料夾居然不在E盤，而在D盤的Altera程式目錄下的Workspace裡，於是File -- Switch Workspace，把Workspace路徑設定成當前

Holy！

新的問題：

求教大神指點迷津？？？？
