You can use the "format elf ..." directive to create a file that can be linked with the standard C linkers.
Code: ; fasm example of using the C library in Unix systems ; compile the source with commands like: ; fasm libcdemo.asm libcdemo.o ; gcc libcdemo.o -o libcdemo ; strip libcdemo format ELF include 'ccall.inc' section '.text' executable public main extrn printf extrn getpid main: call getpid ccall printf, msg,eax ret section '.data' writeable msg db "Current process ID is %d.",0xA,0 |

Is it not possible without elf or any format ?
And how you link your program and specify start address point ? When i use ld, i have error because i have 64 bits platform... |

For 64 bits I think you need "format ELF64".
You might be able to link other formats (mscoff maybe?), but it depends upon your linker, and it depends upon your C code generating something compatible also. |

I need ELF64 ? But the output is ELF ?

You will have to ask your linker to make the raw binary after the linking stage.

And how you do that ?

That depends upon your linker program. Are you using ld?
I remember that MASM had a separate program called exe2bin for converting PE files to binary. |
