[英]Trouble Compiling my Microchip PIC18f4550 USB project using MPLAB X IDE C18 compiler. The compiler keep highlighting "syntax error" and won't compile
[英]Error on compiling c file on MPLAB X ide
在Windows上尝试使用MPLAB X进行编译时,出现以下错误。
newmain.c:40:9: error: unknown configuration setting: 'JTAGEN'
newmain.c:61:2: error: 'LATA' undeclared (first use in this function)
newmain.c:62:2: error: 'TRISA' undeclared (first use in this function)
newmain.c:61:2: error: 'LATA' undeclared (first use in this function)
我在2台不同的计算机上(在Windows 8.1和Vista上)尝试了此操作,但是它们都给了我相同的错误。
好像xc.h文件已经包含在项目中,因为我可以打开该文件。 我也用谷歌搜索这个问题,但是没有解决方案。
如果您能给我解决该问题的方法,我非常感谢。
我还附上描述该项目项目属性的照片。

您收到的错误表明编译器没有看到任何库引用这些寄存器。 而是将它们视为常规变量。
您应该包括正在使用的处理器的特定头文件,并检查其中包含哪些寄存器以使您的问题更有意义。
