请问为什么在编译IS0-MINI光盘中“野火emWin_ISO_MINI例程\0.ISO_MINI_gui”工程会出现如下错误呢??
..\..\Output\WFGUI.axf: Error: L6218E: Undefined symbol abort (referred from pngread.o).
..\..\Output\WFGUI.axf: Not enough information to list image symbols.
..\..\Output\WFGUI.axf: Finished: 1 information, 0 warning and 1 error messages.
