Use GCC and NASM to compile together in Linux

Today, we compiledProgram
First, use NASM to compile an ASM file in ELF format. The Assembly file contains global _ start and functionc, which will be used for future connection. Extern is used to represent functions in the external C language.

Call structure of my program: _ start (ASM)-> funb (c)-> func (ASM)
Among them, the ASM files include extern funb, global _ start, and global func.
C file Declaration: void func ();

Function parameter transfer: Use push to passAddress
Instead of numeric values. Finally, caller is needed to clear the parameters.

Required command line:

NASM-F elf-oDest
. OSRC
. ASM

Gcc-c-oDest2
. OSrc2
. C (-C means only compile)

LD-s-oFinal
. ODest
. ODest1
. O
