Not sure if this is missing a library or some other issue?
MacOS 10.14.5, Python 3.7, Panda3D 1.10.3

This is because the Panda3D SDK was compiled with an older (ancient) version of xcode which used -stdlib=libstdc++, but newer versions only support -stdlib=libc++. You can either try to compile LUI with xcode 4.4.1 (I couldn't get it to work) or compile the Panda SDK with a newer version of xcode.

If you want to compile with a newer xcode, this is what I did to get it to work:

# Install some requirements beforehand. There may be more which I already had installed.
brew install yasm
brew install icu4c
brew install python3
export PKG_CONFIG_PATH="/usr/local/opt/icu4c/lib/pkgconfig"

# Building panda-thirdparty - these are required to build the Panda3D SDK. I skipped bullet because I can't get it to compile.
git clone https://github.com/treamology/panda3d-thirdparty.git
cd panda3d-thirdparty
# This is important! This branch has the changes needed for newer versions of MacOS.
git checkout ios
mkdir build
cd build
# NOTE: the output will be in ../darwin-libs-a
cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_BULLET:BOOL=FALSE ..
cmake --build . --config Release

# Go back to the top level.
cd ../../

# Building panda
git clone https://github.com/panda3d/panda3d.git
cd panda3d

# Copy the third party stuff over to here.
mkdir thirdparty
cp -R ../panda3d-thirdparty/darwin-libs-a thirdparty/

# You might need to change your osxtarget depending on your MacOS version.
python3 makepanda/makepanda.py --everything --no-bullet --osxtarget 10.15 --threads 4 --python-incdir=/usr/local/Cellar/python/3.7.4_1/Frameworks/Python.framework/Versions/3.7/include --python-libdir=/usr/local/Cellar/python/3.7.4_1/Frameworks/Python.framework/Versions/3.7/lib --installer

# Go back to the top-level directory.
cd ..

# Now you have an installer for the Panda3D SDK. You need to do a couple of things to install it (especially if you are using MacOS 10.15 which makes the root directory read-only).

# 1. open disk utility
# 2. Click file -> New Image -> Blank Image
# 3. Name it PandaSDK-1_11_0
# 4. Set size to 1 GB
# 5. Click save and it should be mounted automatically but if it isn't, then mount it.
# 6. Run your new Panda3D SDK installer, and when you get to the drive selection, select your volume you just created.
# 7. VERY IMPORTANT select back and make sure to check to install the headers. Whenever you change the drives it will uncheck that option...

# Now that you have the SDK installed, we can finally compile lui.
git clone https://github.com/tobspr/LUI.git
cd LUI
python3 update_module_builder.py
VERBOSE=1 PYTHONPATH=/Volumes/PandaSDK-1_11_0/Developer/Panda3D python3 build.py

# Finally you should have lui.so compiled, now we just need to add it to the sdk.
cp osx_amd64_panda1.11.0_py37/lui.so /Volumes/PandaSDK-1_11_0/Developer/Panda3D/panda3d/

# Now make python find the panda python files and try importing lui.
export PYTHONPATH=/Volumes/PandaSDK-1_11_0/Developer/Panda3D python3 -c "import panda3d.lui"

# Great! Now you have LUI compiled! A couple of gotchas:
# 1. A lot of the LUI code uses unicode(). If you're in python3, you need to replace this with str().
# 2. IMPORTANT!!! In your prc file for panda you need
#	gl-version 3 2
#
#	For example:
#		from panda3d.core import load_prc_file_data
#		load_prc_file_data("", """
#		    text-minfilter linear
#		    text-magfilter linear
#		    text-pixels-per-unit 32
#		    sync-video #f
#		    textures-power-2 none
#		    show-frame-rate-meter #t
#		    win-size 700 600
#		    window-title LUI Minimal Example
#		    gl-version 3 2
#		""")
#	If you forget this, then LUI won't render correctly.

I made this script by looking through my bash history, so there may be a small mistake somewhere. Let me know if you run into any trouble and I can help you get it sorted out. If this is too much work, I can also just upload the volume I created with the Panda3D SDK including lui.so.
