Currently advised way to build sage from a fresh git clone

[Maarten Derickx]

Hi All,

I haven't had a development version of sage for some time, and now am setting one up again. In setting it up I found out that both my understanding of how to do a build from a fresh git clone for some time ago, as well as the current developer documentation don't seem to matching the current situation anymore.

Here is how I got a working sage installation:

git clone git://github.com/sagemath/sage.git #I realize I need to add git.sagemath.org later

make #gives an error that I should run configure first

./configure 

make

The ./configure used and second make to be unnecessary according to my memory and the documentation on https://doc.sagemath.org/html/en/developer/walk_through.html#obtaining-the-sage-source-code 

Additionally the ./configure command is not available until you run make at least once, so is there a step that I am missing (or an argument to the first make) so that I don't get an error after the first make?

Thanks,

Maarten

Running `configure` before `make` became mandatory after

- Sage Trac ticket 29316: Require ./configure before make

  https://trac.sagemath.org/ticket/29316

merged in Sage 9.2.beta2.

With that in mind, the steps are now as follows.

Clone and change to the obtained folder:

```

$ git clone ...

$ cd ...

```

Then either

```

$ make configure

$ ./configure

$ make

```

or

```

$ ./bootstrap

$ ./configure

$ make

```

or if you like quiet:

```

$ git clone ... -q

$ cd ...

$ ./bootstrap -q

$ ./configure -q

$ ./make -s V=0

```

Happy building Sage!  --Samuel

Our README.md is up to date. Unfortunately, the section "Sage Development Process" in Developer's Guide is not.

https://trac.sagemath.org/ticket/29784 describes the task of updating this section - which needs help.
