OK say I have 2 object (ELF object, unix/linux), the first is written in c, second in fasm, now i want to encorporate fasm's "file" directive into my c program, so my question is, how can i make a variable in fasm that i can use in my c application. btw I am using gcc on linux ubuntu, but I will be porting using mingw, on windows.

The way to achieve that is with the use of extrn/public and use a linker.

Do you want to extract "file" functionality from fasm or getting the file contents from an assembly source which contains a "file" directive invocation somewhere?

I want to have an asm file like:

format ELF

file variable, "SOMEFILE"

C File:

int main() {
printf("Variable: %s", variable);
}

compile with like:

fasm test.asm test.o
gcc main.c -c -o main.o
gcc main.o test.o -o test

NOTE: I wrote this quickly so it may not be correct

Put 'variable' as public in the fasm file and as extrn in the C file and rewrite the line as "variable: file 'SOMEFILE'".
