Building SolveSpace Web Edition

Based on instructions here

Install prerequisites

sudo apt install git build-essential cmake

Install emscripten

./emsdk install latest

# Make the "latest" SDK "active" for the current user. (writes .emscripten file)
./emsdk activate latest

# Activate PATH and other environment variables in the current terminal
source ./emsdk_env.sh

Build

In an emscripten window, from above step:

git clone https://github.com/solvespace/solvespace
cd solvespace

# 'Web Edition' code is on a branch
git checkout emscripten

git submodule update --init
mkdir build
cd build
emcmake cmake .. -DCMAKE_BUILD_TYPE=Debug
make

Issues

• still experimental
• file open/save/export/import causes a crash

Further work

• how to build from source
• fix/avoid crashes
• implement open/save/export/import
