OpenELP is an open source EchoLink proxy for Linux and Windows. It aims to be efficient and maintain a small footprint, while still implementing all of the features present in the official EchoLink proxy.

OpenELP also has the ability to bind to multiple network interfaces which are routed to unique external IP addresses, and therefore is capable of accepting connections from multiple clients simultaneously.

To build OpenELP you will need:

• CMake
• pkg-config
• GCC or Visual Studio

If available, OpenELP can use:

• PCRE2
• OpenSSL
• Doxygen

If your system doesn't have PCRE2 development files installed, you have the option of bundling PCRE2 with OpenELP. To do this, specify -DOPENELP_BUNDLE_PCRE:BOOL=ON when you call cmake. CMake will download the PCRE2 sources automatically and build them into the OpenELP library.

To create a Windows installer, you will also need to install NSIS

The only runtime dependency that OpenELP has is on the PCRE2 shared library, unless PCRE2 was bundled into OpenELP.

To install these prerequisites on Fedora and RHEL (w/EPEL), run:

sudo dnf install cmake doxygen gcc pcre2-devel pkgconfig openssl-devel

Linux:

mkdir build && cd build
cmake ..
make

Windows:

mkdir build && cd build
cmake .. -DOPENELP_BUNDLE_PCRE:BOOL=ON
devenv openelp.sln /build

Windows Installer:

devenv openelp.sln /project PACKAGE /build
