Compiling Emacs 27.1 on Fedora 32
Emacs 27.1 is out! It's another great release and has been behaving rather well from my experience. If you're curious about giving it a go, here's how to install on Fedora 32, assuming you're running Fedora Workstation and building the GTK+ frontend:
Getting the release
cd ~/Downloads # or any folder of your choice curl -L -O https://ftpmirror.gnu.org/emacs/emacs-27.1.tar.xz tar xf emacs-27.1.tar.xz && cd emacs-27.1
Installing deps
Emacs requires some basic libraries installed, which I've ironed out to these:
sudo dnf install -y \
make \
automake \
gcc \
gcc-c++ \
kernel-devel \
gtk3-devel \
libjpeg-devel \
libXpm-devel \
giflib-devel \
libtiff-devel \
gnutls-devel \
ncurses-devel
Configuration flags
--with-cairo
Emacs can use Cairo for drawing; it's disabled by default because considered experimental but a thread from last year was already considering making it the default. I use it without problems.
--with-json
Emacs ships with much faster JSON handling, through the jansson library. It's enabled by default (so we don't actually need to specify it) but if you dont' have the library installed, it will silently skip it.
sudo dnf install -y jansson-devel
--with-librsvg
In a similar fashion to JSON, Emacs enables support for SVG by default but will not install it if you're missing the underlying library.
sudo dnf install -y librsvg2-devel
Configure & install
That's enough for me, so we just need to go ahead and install it.
./configure --with-json --with-cairo --with-librsvg make sudo make install
Run emacs --version, make sure you're on 27.1 and
off you go!
Enjoy Emacs.
Afterword
To make sure I got this right without relying on my current system (which is full of bits and bobs) I built a simple Docker image from Fedora 32 (with the added Workstation group) and checked my instructions there. For reference:
FROM fedora:32
WORKDIR /tmp/emacs
RUN dnf update -y
RUN dnf group install "Fedora Workstation" --skip-broken -y
