Re: Building Emacs on WSL

[Angelo Graziosi <angelo.graziosi@alice.it>]

Just for the record...

I adopted the workaround suggested in etc/PROBLEMS (and from the WEB [*]):

   echo 0 | sudo tee /proc/sys/kernel/randomize_va_space

and with it I was able to build,

./autogen.sh

CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe" LDFLAGS="-pipe" CC="gcc" 
./configure --prefix=/opt/emacs --build=x86_64-pc-linux-gnu --without-x 
--with-gnutls=no --disable-acl

make -j3


Emacs25 from the following source packages:

emacs-25.1.90.tar.gz
emacs-25.1.tar.gz
emacs-emacs-25.tar.gz (2016-12-11 10:50"17, 467768f64ee109fe)


BUT NOT emacs-master.tar.gz from master whose build always hangs as I 
described (./temacs --batch... see below)

At least, now I have an Emacs build (noX) working inside WSL!

Ciao,
Angelo.
