map file 对于嵌入式开发是非常有用的,尤其是当你开发的module引起了 kernel panic 的时候。
仅写作Mark用
make:
$vim makefile
(add "LDFLAGS=-Map=your_file.map" to your *makefile* or just add it to your make command every time, it ups to you.)
$find / -name "your_file.map"
(Usually, It's in your current directory, but if you use a "make -C " in your makefile, it will be there.)
gcc/g++
$gcc -o your_file.c -Wl,-Map=your_file.map
(It definitely should be in your current dirctory).
