麻烦的地方来了,gcc中不支持at直接指定变量位置的写法,因此报错如下: $ make ./Src/MALLOC/malloc.c:12:1: warning:'at' attribute directive ignored [-Wattributes]u8mem2base[MEM2_MAX_SIZE] __attribute__((at(0x68000000)));//外部SRAM内存池^ ./Src/MALLOC/malloc.c:13:1: warning:'at' attribu...

在使用一些第三方库或源码的时候,经常会遇到编译时产生warnings情况,这些warning不是我们自己的代码产生的,当然也不好去修改,但每次编译都显示一大堆与自己代码无关的警告也着实看着不爽,更麻烦的是还有可能造成自己代码中产生的警告被淹没在多过的无关警告中,而被忽略掉的情况。
The effect of this is that GCC may, effectively, mark inline methods with "__attribute__ ((visibility ("hidden")))" so that they do not appear in the export table of a DSO and do not require a PLT indirection when used within the DSO. Enabling this option can have a dramatic ...
