/doc/使用nasm和gcc生成无格式的二进制文件.txt: -------------------------------------------------------------------------------- 1 | 提供下面两种方法编译生成一个没有格式的二进制文件： 2 | 1. 3 | 　　gcc -c test.c 4 | 　　ld -o test -Ttext 0x0 -e main test.o 5 | 　　objcopy -R .note -R .comment -S -O binary test test.bin 6 | 7 | 2. 8 | 　　gcc -c test.c 9 | 　　ld test.o -o test.bin -Ttext 0x0 -e main -oformat binary 10 | 11 | 　　现在假设我们有一个段使用汇编编写的程序，而我们又需要将它加入我们最后生成的文件中，我们可以使用下面的方法： 12 | 13 | 　　nasm -f elf other.asm -o other.o 14 | 　　gcc -c test.c 15 | 　　ld other.o main.o -o kernal.bin -Ttext 0x0 -e _mian --oformat binary 16 | 17 | 　　目前linux大多都是elf格式目标文件，所以我们首先将汇编程序编译为elf的目标文件，然后使用ld将多个目标文件链接到一起即可。 18 | -------------------------------------------------------------------------------- /doc/使用开源软件-自己动手写操作系统WriteOS.pdf:
