I tried to make a Build.bat file that Assembles, Compiles, Linkes, and Makes a Floppy called "build.bat"
The file is below anyone know why this doesn't work?
(Yes I looked at the Make File Tutorial)( And Googled it!)
!!UPDATED MAKEFILE!! and ERROR

Batch files don't work in linux. And this isn't a makefile. I posted a makefile for you on another thread.

Troll or incompetent noob, community, take your pick.
Linux =/= DOS & Windows. Makefiles are files that describe how the "make" command should work.

Ubuntu (Linux)?
Anyway, I'm not very familiar with makefiles. I've only use batch scripts for large projects (or IDEs). But from what I gather from the GNU Make documentation, this should have worked, right?
Code: Select all
foo.asm : foo.bin
nasm -ofoo.bin foo.asm
I'm using mingw32-make. Am I doing something wrong? And please, don't just answer
use cygwin or msys instead; I wanna know if there's something I'm missing here. It complains about there being no rules defined for foo.asm.

Use Linux Instead... jk. Though it would be a good idea.
It won't work for three reasons:
1. 'foo.asm : foo.bin' is backwards. Makefiles use 'target : dependencies'. foo.bin depends on foo.asm.
2. You must include a target called 'all'. After fixing the previous error, just add
By default make starts with all and branches out from there.
3. You must add 'foo.asm: ' at the end of the makefile. Otherwise, make won't check if foo.asm has been changed since the last build.
I recommend makefiles that build all .c and .asm files in a directory, so you don't have to change your makefile every time you add a file. However, it is up to you.

Oh, I did do that... I don't know why I got them reversed on the forum.
Anyway, thanks for the quick reply.

How do you know what commands you can use in Linux make files?
Not a ton of Linux experience
Windows Example Command: Echo Text

Simple -- you're not using makefiles with linux, you're using them with a tool called 'make'. It is used of automatically compiling/assembling/whatever (not limited to software development) only when certain files are updated (timestamps are checked). This tool can also be used under Windows; for example MinGW comes with a version of make (mingw32-make.exe). You can check the documentation
here.

In other words:
Read what we post: makefiles are not shell scripts. Makefiles are for the "make" command. Shell scripts are like Linux batch files, but more powerful. Read the wiki's
makefile tutorial again.

Note that in later versions of Windows, certain extensions may be activated. Also, they're working on a much more powerful scripting thingy called Windows PowerShell, but I'm not sure it's included with Windows or you have to download it from Microsoft's website (and I'm too lazy to check -- I don't have Windows on this machine).

You do have to download powershell, but IMHO it's confusing and a little awkward to work with.

Make is more like a really simple language, so you need to learn "syntax" more than commands. It doesn't take that long to learn, and the time spent learning it has a very good ROI.
In general, you can use any shell-based application in make (such as echo, gcc,
rm, etc.).
Just a note, nearly unrelated to this topic, you may also want to learn "shell scripting". In Linux, many programs have a command-line equivalent, so you can do some pretty interesting things in a short amount of time.
