編譯公用程式
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果預先編譯的公用程式不符合需求,您可以自行建構 WebP 公用程式。
使用 Visual C++ 在 Windows 上編譯
從下載清單下載 libwebp-1.6.0.tar.gz
,然後解壓縮內容。
從 libwebp-1.6.0
目錄執行:
nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output
如要查看其他選項,請執行:
nmake /f Makefile.vc
視目標平台而定,目錄 output\release-static\x86\bin
或 output\release-static\x64\bin
會包含工具 cwebp.exe
和 dwebp.exe
。output\release-static\(x86|x64)\lib
目錄會包含 libwebp
靜態程式庫。
Linux
安裝 libjpeg
、libpng
、libtiff
和 libgif
套件,以便在 JPEG、PNG、TIFF、GIF 和 WebP 圖片格式之間轉換。
套件管理方式會因 Linux 發行版而異。在 Ubuntu 和 Debian 上,下列指令會安裝所需套件:
sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev
完成安裝程序 (請參閱下文)。
macOS
MacPorts 是滿足依附元件的便利方式。如已安裝 MacPorts,請直接前往步驟 3。如果沒有,請按照下列步驟操作:
前往 MacPorts
下載網站,下載適用於 macOS 版本的 MacPorts。MacPorts 需要安裝 Xcode。
按照 MacPorts 的指示安裝 MacPorts。
更新 MacPorts:
sudo port selfupdate
安裝 JPEG、PNG、TIFF 和 GIF 依附元件:
sudo port install jpeg libpng tiff giflib
完成安裝程序 (請參閱下文)。
Cygwin
從 Cygwin 網頁下載 setup.exe。
執行 setup.exe,然後繼續安裝。
在「選取套裝方案」畫面中,將下列項目新增至預先選取的套裝方案:
完成安裝程序 (請參閱下文)。
建築物
從下載清單下載 libwebp-1.6.0.tar.gz
。
解壓縮套件。這項操作會建立名為 libwebp-1.6.0/
的目錄:
tar xvzf libwebp-1.6.0.tar.gz
建構 WebP 編碼器 cwebp
和解碼器 dwebp
:
前往 libwebp-1.6.0/
的解壓縮目錄,然後執行下列指令:
cd libwebp-1.6.0
./configure
make
sudo make install
這會建構並安裝 cwebp
和 dwebp
指令列工具,以及 libwebp
程式庫 (動態和靜態)。
這些工具通常會預設安裝在 /usr/local/bin/
下方。本機版本會建構在 examples/
目錄下。
程式庫通常會安裝在 /usr/local/lib/
目錄下。為避免發生執行階段錯誤,請確認 LD_LIBRARY_PATH
環境變數包含這個位置。C 標頭通常會安裝在 /usr/local/include/webp
下方。
如要查看其他選項,請執行:
./configure --help

Download `libwebp-1.6.0.tar.gz` from the [downloads list](https://storage.googleapis.com/downloads.webmproject.org/releases/webp/index.html)\n and extract its contents.\n\n2. From the `libwebp-1.6.0` directory, run:\n\n nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output\n\n To see additional options, run: \n\n nmake /f Makefile.vc\n\n3. The directory `output\\release-static\\x86\\bin` or\n `output\\release-static\\x64\\bin` will contain the tools `cwebp.exe` and\n `dwebp.exe` depending on the platform being targeted. The directory\n `output\\release-static\\(x86|x64)\\lib` will contain the `libwebp` static\n library.\n\nCompiling on Unix-like Platforms\n--------------------------------\n\n### Preparing the Platform\n\n#### Linux\n\n1. Install the `libjpeg`, `libpng`, `libtiff` and `libgif` packages, needed to\n convert between JPEG, PNG, TIFF, GIF and WebP image formats.\n\n Package management varies by Linux distribution. On Ubuntu and Debian, the\n following command will install the needed packages: \n\n sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev\n\n2. Complete the installation ([see below](#building)).\n\n#### macOS\n\nMacPorts is a convenient way to satisfy dependencies. If you already have\nMacPorts installed, go directly to Step 3. Otherwise, follow these steps:\n\n1. Download MacPorts for your macOS version from the MacPorts\n [downloads site](https://distfiles.macports.org/MacPorts). MacPorts requires\n the installation of\n [Xcode](https://developer.apple.com/xcode/).\n\n2. Install MacPorts following the MacPorts\n [directions](https://guide.macports.org/).\n\n3. Update MacPorts:\n\n sudo port selfupdate\n\n4. Install the JPEG, PNG, TIFF and GIF dependencies:\n\n sudo port install jpeg libpng tiff giflib\n\n5. Complete the installation ([see below](#building)).\n\n#### Cygwin\n\n1. Download setup.exe from the [Cygwin web page](https://www.cygwin.com).\n\n2. Run setup.exe and proceed through the installation.\n\n3. At the **Select Packages** screen, add to the pre-selected packages the\n following:\n\n - `libjpeg-devel`, `libpng-devel`, `libtiff-devel` and `libgif-devel`\n\n - `gcc`, `make` and `automake` (for building packages)\n\n4. Complete the installation ([see below](#building)).\n\n### Building\n\n1. Download `libwebp-1.6.0.tar.gz` from the\n [downloads list](https://storage.googleapis.com/downloads.webmproject.org/releases/webp/index.html).\n\n2. Untar or unzip the package. This creates a directory named `libwebp-1.6.0/`:\n\n tar xvzf libwebp-1.6.0.tar.gz\n\n3. Build WebP encoder `cwebp` and decoder `dwebp`:\n\n Go to the directory where `libwebp-1.6.0/` was extracted to\n and run the following commands: \n\n cd libwebp-1.6.0\n ./configure\n make\n sudo make install\n\n This builds and installs the `cwebp` and `dwebp` command line tools, along\n with the `libwebp` libraries (dynamic and static).\n\n These tools are usually installed under `/usr/local/bin/` by default. The\n local versions are built under the `examples/` directory.\n\n The library will usually be installed under the `/usr/local/lib/` directory.\n To avoid run-time errors, make sure that your `LD_LIBRARY_PATH` environment\n variable includes this location. The C headers are typically installed under\n `/usr/local/include/webp`.\n\n To see additional options, run: \n\n ./configure --help\n\nWhat Next?\n----------\n\nGo to [Using WebP](/speed/webp/docs/using) for instructions on how to start\nconverting your images."]]
