Help Building Binutils

Hello!
I've been following the wiki tutorial on how to build my compiler and im running into a bit of a problem,
Code: Select all
mkdir build-binutils
cd build-binutils
../binutils-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot --disable-nls --disable-werror
do i need to have '/binutils-x.y.z/configure' in my '/src' directory, is it already on the cygwin system or am i just dumb?
Thanks in advance!
(sorry if this isn't the correct place to post this issue
)

It's hard to say because you didn't post any error messages, but here's how I built binutils on cygwin:
Code: Select all
export PREFIX=/usr/local/x86_64-elf
export TARGET=x86_64-elf
export PATH="$PREFIX/bin:$PATH"
cd build-binutils
../binutils-2.34/configure --target=$TARGET --prefix=$PREFIX --with-sysroot --disable-nls --disable-werror
make ; make install
There may be some library prerequisites. I'm not remembering which at the moment, but I think I remember that the cygwin repository didn't offer all of them and some had to be built from source.

binutils-x.y.z is a placeholder for whatever version of binutils you are building.
For example, for binutils 2.31, you would download and extract it.
It should produce the binutils-2.31 folder.
Then you would create and cd into your build-binutils folder.
Then you would execute the configure script in the binutils-2.31 folder by doing ../binutils-2.31/configure <arguments>

Oh, i'm sorry.
I'm using Cygwin and installed binutils with the package selection thing, i just need to build it.
Code: Select all
../binutils-2.34/configure --target=$TARGET --prefix=$PREFIX --with-sysroot --disable-nls --disable-werror
-bash: ../binutils-2.34/configure: No such file or directory
is there a specific directory it is in or...

configure should definitely be at the top level of the binutils-x.y.z directory.
I would just download the binutils-x.y.z sources from gnu.org and build them. That's what I did (binutils 2.34 on cygwin64/Win10). Both it and gcc built just fine for both 32-bit and 64-bit elf targets.

The tree should look something like this:
Code: Select all
|
├── binutils-2.31.1
│ └── configure
├── build-binutils
├── build-gcc
└── gcc-7.3.0
└── configure
To build binutils, cd into build-binutils, then run the ../binutils-2.31.1/configure command.
To build gcc, cd into build-gcc, then run the ../gcc-7.3.0/configure command

The binutils you install via your platform's package manager -- no matter whether that's Cygwin, Windows, Linux or something else -- is a ready-built package of binutils
binaries that are targeted
for your platform. That is fine if you want to use the binutils to handle binaries
for your platform. For building your "My Own OS" compiler, they are not necessary.
If you want to
build your
own binutils, targeting your
own "My Own OS" platform, you start with the
sources for binutils, which you can (and should!) download
directly from the GNU.org FTP server.
The "binutils-x.y.z" directory mentioned in the Wiki How-To is
the directory where those sources are located.

Oooooh..
That makes much more sense now, sorry.
Thanks for explaining it to me!
