Building Emacs with MinGW 64

Building Emacs with MinGW 64

[Ruslan Bekenev]

Hello Everyone,
I'm currently trying to build Emacs from source on my Windows machine.

I have mingw 64 installed and when I'm running "config.bat msdos" I'm 
getting error that DJGPP isn't installed. And it's truth actually. 
Moreover after installation of DJGPP I've noticed its binaries cannot be 
running on 64 bit system (can't I just find x64 version or is it not 
exists?).

I also have found some build instructions in the web that use MSYS2 
package. This is not what I want to use though.

Is there any workaround to build Emacs without DJGPP and MSYS2?

Excuse me if this is some kind of silly question or I've asked it in 
wrong way... mailing lists are pretty new to me.

P.S.
I'm on Windows 10 64 bit building emacs from current master branch.

You should look at the instructions that come with Emacs first. There
is nt/INSTALL for building with MSYS and mingw32 (I believe this can
only produce 32 bit binaries). nt/INSTALL.w64 describes building with
MSYS2 and mingw64 (this can produce both 64 bit and 32 bit binaries).

You don't explain exactly why you don't want to use MSYS2. Building
Emacs requires gcc, development libraries+headers and a bourne-shell
(or derivative like GNU bash) with standard Unix command line
utilities. MSYS and MSYS2 provide a simple packaged way of installing
these. The nt/INSTALL instructions explain how to install mingw32
separately from MSYS, but I don't know that you can avoid it entirely.

Thank you for the answer, Noam.

Sure I did. But thank to your message I noticed NT folder which I've 
missed.

I'm just afraid it's another toolchain I have to keep on my system and I 
have to make sure it's not conflicting with other. As far as I got MinGW 
has GCC and Make and some other tools like sed, grep, sh, etc. So I 
didn't get the point of using MSYS2.

But anyway, thank you again for your answer. I'll try to look deeper to 
the MSYS2. I guess I've just misunderstood the purpose of msys.

You are not alone; the msys and mingw websites do a terrible job of
explaining this.

Roughly, msys is for running bash scripts like configure, while mingw is
the runtime libraries.

MinGW is also the development tools: the compiler, the linker,
Binutils, etc.

There are scripts in admin/nt/dist-build for the entire build based on
msys. They can produce both 64 and 32 binaries as well as packaging all
the dependencies, so you can move the final product independent of an
msys2 installation.
