TouchGFX選擇開發板STM32F769I_DISCO，應用模板為空白模板，點擊生成代碼，完成后，用MDK5打開編譯后報錯，提示找不到C++的頭文件hpp文件，這個報錯一度困擾我很久，最后偶然找到解決方法。

話不多說，直接介紹我的解決方法：
其實很簡單，就一句話：先用TouchGFX建造工程，並生成代碼工程，生成的工程文件夾里面有一個STM32CubeMX的工程文件，打開，再用STM32CubeMX生成代碼工程（不要改變任何配置，包括工程路徑和名字，除了一點，下面會提到）。然后，再一次用TouchGFX生成代碼工程，之后用MDK5打開工程就可以正常編譯通過了！
注意：
=》工程目錄下會有兩個STM32CubeMX工程文件，例如我的兩個文件是：STM32F769I_DISCO.ioc和backup_STM32F769I_DISCO.ioc，打開前者，后者是備份文件，無需理會。
=》如果用STM32CubeMX打開文件出現如圖所示提示，點擊中間的“Migrate”按鈕
=》在Project Manage選項卡里面，Toolchain/IDE選項默認是STM32CubeIDE，將其改為MDK-ARM，版本號的話，筆者選的是V5.27，其他版本號沒有測試過。注意，在用STM32CubeMX的過程中，只有這一點需要修改，其他不要改動！
=》再次打開TouchGFX的這個工程（筆者用STM32CubeMX時是關閉TouchGFX的，打開沒試過），點擊右上角Generate Code再一次生成代碼工程，完畢后，打開MDK編譯即可通過。
=》編譯通過后會有一個警告：STM32F769I_DISCO.sct(18): warning: L6314W: No section matches pattern *.o(ExtFlashSection).，這是因為這個應用模板是空白模板，沒有任何數據存在外部flash中，什么圖片啊，字體啊什么的。所以這個警告無需理會，要想驗證的話可以在TouchGFX中隨便顯示張圖片，這個警告就會消失了。親測有效。
