Endorphin is still in development, which means that there are no compiled installable packages yet. To try the latest code, follow this guide.
To see if git is installed, open up a terminal window and type git. If it is not installed, the terminal will report back command not found. If it is installed, you'll receive the git help text. To install git: Windows, Mac, and for Linux, use your distro's package manager.
If you already have Qt 5.14 or greater installed, you can skip this step. To install Qt 5.14, visit the Download Page or use your distro's package manager on Linux. Be sure to add the correct PATH variable if required in the official install instructions. When you're done, skip the alternative method section, and move onto Step 3.
Now we will download the latest tree of Endorphin. Issue these commands:
$ git clone git://github.com/EndorphinBrowser/browser.git
$ cd browser
$ mkdir build && cd build
$ cmake ..
$ make -j$(nproc)
Endorphin is now compiled. To run endorphin, simply run ./endorphin from the current directory.
Optional: To update to the latest Endorphin in the future, you can issue these commands:
$ cd browser
$ git pull
$ cd build
$ make -j$(nproc)
If you are looking for an IDE to develop Endorphin in you can checkout the free IDE Qt Creator that is available with Qt.
