1. Building FreeType 1. Сборка FreeType

SDL3_ttf depends on FreeType. We need to build it for Wasm first. SDL3_ttf зависит от FreeType. Сначала нам нужно собрать его для Wasm.

• Download FreeType 2.14.3 from GitHub. Скачайте FreeType 2.14.3 с GitHub.
• Unzip it to C:/libs. Распакуйте в C:/libs.
• Open CMD as Administrator and navigate to the folder: Откройте CMD от имени администратора и перейдите в папку:

  cd C:\libs\freetype-VER-2-14-3

Run these commands to configure, build, and install:Выполните эти команды для настройки, сборки и установки:

emcmake cmake -S . -B dist -DCMAKE_INSTALL_PREFIX="C:/libs/freetype-2.14.3-wasm" -DCMAKE_BUILD_TYPE=MinSizeRel
cmake --build dist
cmake --install dist

2. Building SDL3_ttf 2. Сборка SDL3_ttf

• Download SDL3_ttf 3.2.2 source from GitHub. Скачайте исходники SDL3_ttf 3.2.2 с GitHub.
• Unzip it to C:/libs and enter the directory: Распакуйте в C:/libs и перейдите в директорию:

  cd C:\libs\SDL3_ttf-3.2.2

• Create a file named config-wasm.bat inside this folder with the following content: Создайте файл config-wasm.bat внутри этой папки со следующим содержимым:

emcmake cmake -S . -B dist ^
  -DCMAKE_INSTALL_PREFIX=C:/libs/SDL3_ttf-devel-3.2.2-wasm ^
  -DSDL3_DIR="C:/libs/SDL3-devel-3.4.8-wasm/lib/cmake/SDL3" ^
  -DFREETYPE_INCLUDE_DIR_freetype2=C:/libs/freetype-2.14.3-wasm/include ^
  -DFREETYPE_INCLUDE_DIR_ft2build=C:/libs/freetype-2.14.3-wasm/include/freetype2 ^
  -DFREETYPE_LIBRARY_DEBUG=C:/libs/freetype-2.14.3-wasm/lib/libfreetype.a ^
  -DFREETYPE_LIBRARY_RELEASE=C:/libs/freetype-2.14.3-wasm/lib/libfreetype.a ^
  -DCMAKE_BUILD_TYPE=MinSizeRel ^
  -DSDLTTF_SAMPLES=OFF

Run the script and build: Запустите скрипт и соберите проект:

config-wasm
cmake --build dist
cmake --install dist

set(SDL3_DIR "C:/libs/SDL3-devel-3.4.8-wasm/lib/cmake/SDL3")
set(SDL3_ttf_DIR "C:/libs/SDL3_ttf-devel-3.2.2-wasm/lib/cmake/SDL3_ttf")
set(FREETYPE_INCLUDE_DIRS "C:/libs/freetype-2.14.3-wasm/include")
