LSPServer uses a Wolfram Language kernel to generate code at build time and a C++ compiler to compile a native library.
LSPServer uses C++11 features and requires a compiler that can support at least C++11.
LSPServer uses CMake to generate build scripts.
Here is an example transcript using the default make generator to build LSPServer:
cd lspserver
mkdir build
cd build
cmake ..
cmake --build .
The result is a directory named paclet that contains the WL package source code and a built LSPServer .paclet file for installing.
Inside a kernel session you may then install the paclet by evaluating:
PacletInstall["/path/to/build/paclet/LSPServer-1.9.paclet"]
Specify MATHEMATICA_INSTALL_DIR if you have Wolfram System installed in a non-default location:
cmake -DMATHEMATICA_INSTALL_DIR=/Applications/Mathematica.app/Contents/ ..
cmake --build .
On Windows:
cmake -DMATHEMATICA_INSTALL_DIR="C:/Program Files/Wolfram Research/Mathematica/13.1" ..
cmake --build .
You can install the paclet from CMake:
cmake --install .
This starts a kernel and calls PacletInstall with the built .paclet file.
