MPLAB使用procdefs.ld作为加载程序配置文件：

但是当我尝试在MPLABX中使用相同的文件时，我会遇到多个错误：

如何为MPLABX定义加载程序配置文件？需要对mplabx进行哪些更改？
答案 0 :(得分：0)
我建议改为xc32 v1.40，当前版本，C32已经很老了。 在dir“C：\ Program Files（x86）\ Microchip \ xc32 \ v1.40 \ examples \ xc32_examples \ custom_ld_file”的方框中 是一个带有自定义.ld文件示例的示例项目，其中包含可能有用的注释。 如果您不能/不愿意更改为xc32，我建议您继续使用MpLAB IDE和C32。 X的包含路径非常不同。
