Need help with error compiling webgl-port


I’m compiling the webgl-port branch like this when I get the following errors. It seems the build system was overhauled since I last compiled this. After setting up the environment, I do this:

python2 makepanda/ --nothing --static
export PATH=$PATH:~/projects/panda3d/built/bin:~/projects/panda3d/built/lib
python2 makepanda/ --nothing --no-png --use-egg --use-zlib --no-freetype --use-bullet --no-openssl --use-python --use-direct --use-pview --use-gles2 --use-openal --use-vorbis --optimize 4 --outputdir embuilt --target emscripten --no-eg

And get this error:

I have no idea how to approach the file “embuilt/bin/deploy-stub.js” warning nor if it’s important. About Dtool_AddToDictionary, It seems to be declared in ./targetroot/usr/include/panda3d/py_panda.h. I’ve tried every combination of “-I” argument I can think of, but nothing works. I noticed #include "py_panda.h" is in libp3dtoolbase_igate.cxx twice. So, I wonder if it’s picking up one that doesn’t have the declarations.
