Download and install

Linux platform

ArchLinux

The xfel now avaliable at AUR, You can use any AUR helper like yay to download.

yay -S xfel

Windows platform

Get the latest prebuild at RELEASE

Build from source

Linux platform

The xfel tools depends on the libusb-1.0 library, you need to install libusb-1.0-0-dev before compile, for example in ubuntu:

sudo apt install libusb-1.0-0-dev

Then just type make at the root directory, you will see a binary program.

cd xfel
make
sudo make install

Window platform

Windows adopts the cross-compilation method, to install the cross-compilation tool chain in Ubuntu, using:

sudo apt install mingw-w64
sudo apt install autoconf
sudo apt install libtool-bin

And build libusb for cross-compilation.

git clone https://github.com/libusb/libusb.git
cd libusb
./autogen.sh
./configure --host=i686-w64-mingw32 --prefix=/usr/i686-w64-mingw32/
make
sudo make install

Build xfel source code

cd xfel
CROSS=i686-w64-mingw32- make

For 64-bits windows, you can using x86_64-w64-mingw32- instead of i686-w64-mingw32 above.

macOS platform

?> TODO Add macOS ARM support

Before start, make sure the Command Line Tools is installed.

Install libusb using brew

brew install libusb

Then just type make at the root directory, you will see a binary program.

cd xfel
make
