build configuration for emscripten

Im struggling with including paragraph into my libskia.a.

here is my args.gn which successfully being built (but no paragraph in it :( )

# -----------------------------------------------------------------------------
# 2. GPU / Graphics Backend
# -----------------------------------------------------------------------------
# Enable GPU support
skia_enable_gpu   = true

# Use OpenGL / WebGL surfaces
skia_use_gl       = true
skia_use_webgl    = true

# Disable EGL (not needed for Emscripten/WebGL)
skia_use_egl      = false

# Define these flags so Skia knows it’s a GL/Ganesh build
extra_cflags += [
  "-DSK_GL",
  "-DSK_GANESH",  # Enables Ganesh (the Skia GPU backend) explicitly
]

# -----------------------------------------------------------------------------
# 3. Compression / PNG / ZLib
# -----------------------------------------------------------------------------
# Enable zlib; bundle it instead of using system zlib
skia_use_zlib         = true
skia_use_system_zlib  = false

# When building libpng, ensure PNG does not try to enable WebP support
extra_cflags += [
  "-DSK_DISABLE_WEBP=1",
  "-DNDEBUG",
]

# -----------------------------------------------------------------------------
# 4. Font / Text / Internationalization
# -----------------------------------------------------------------------------
# ICU for full Unicode / locale support
skia_use_icu           = true
skia_use_system_icu    = false

skia_enable_skparagraph   = true    # Paragraph API

# FreeType: font rasterizer
skia_use_freetype          = true
skia_use_system_freetype2  = false
skia_enable_fontmgr_empty  = false  # Use a real FontMgr instead of the empty stub

# Extra linker flag to ensure SkDebugf symbols are kept
extra_ldflags += [
  "-Wl,--undefined=_SkDebugf",
]

# -----------------------------------------------------------------------------
# 5. Optional Skia Features

skia_use_wuffs                  = false

# -----------------------------------------------------------------------------
# Enable LTO for smaller, more optimized WASM binary
extra_cflags += [
  "-flto",
]
extra_ldflags += [
  "-flto",
]

here are my commands to build:
rm -rf out/wasm      
bin/gn gen out/wasm --args="$(< /canvas/skia_args.gn)"

ninja -C out/wasm skia

everything is working except for calls to paragraph APIs

last two weeks, I ate google and chatGPT yet not even a small success. I must miss something obvious...

I really appreciate your help and guidance. 

Regards,

Sean

skia_canvaskit_enable_paragraph = true
It might be the problem here.
