MPLAB X 使用 printf 冻结构建

Question

我的设置是：

• MPLAB X IDE v3.40
• C30 编译器 v3.31
• PIC24FJ128GA306

我尝试使用 printf 时出现问题。我可以打印一个字符串，但不能打印一个变量。

这一行是正确的：

printf("HI");

此行未正确构建：

unsigned int var;
var = 1; 
printf("%u", var);

相同的代码与其他 PIC (PIC24FJ512GA606) 和编译器 (XC16) 完美配合。 在这两个项目中，我们都使用来自同一个库 stdio.h 的 printf

当我尝试构建项目时，问题就来了。如果我使用 "printf("%u", var);"并构建它，IDE 挂起，我必须取消构建过程。之后我无法清理项目，IDE 会显示下一个文本：

rm: no se puede borrar build/SF_Utility_v31_RS485/production/interrupts_remapped.o: Permission denied
rm: no se puede borrar build/SF_Utility_v31_RS485/production/mult.o: Permission denied

rm: no se puede borrar build/SF_Utility_v31_RS485/production/SF_internal_comms.o: Permission denied

CLEAN FAILED (exit value 1, total time: 123ms)

如果我转到该文件夹​​并尝试手动删除，则会出现一条消息说我无法删除它，因为“pic30-elf-gcc.exe”正在使用它。我必须关闭该进程，然后您可以使用“printf("Hi");”清理和重建项目...

EDIT1：当我构建项目时，我可以观察到每个文件都被正确编译。问题出在链接器上......当我尝试构建项目时，它会在下一行挂起：

Answer 1

我有办法。问题是我的项目有旧库处于活动状态...取消选中项目配置中的该选项，它现在可以正常运行。
