Compiling Skia from source code under Windows

Draw in the PPAPI, can be combined with third-party graphics library. For example, Cairo, Skia.

Google Chrome, Chromium, and Android all use Skia as the drawing engine. I'll try it, too. Skia, first pass the compile off.

CEF-compiled Skia cannot be used alone

Chromium use Skia. under Windows, compiling CEF from source code illustrates how to compile CEF, which will be chromium by the compiler. There are skia in it, but the skia_library.lib it compiles cannot be used alone and added to the VSProject. Report n multiple link error.

Just good to build it yourself.

Compiling Skia separately

Guide to compiling Windows: https://skia.org/user/quick/windows. First of all, you have Python system. We've compiled CEF, we've got it.

Download Skia here: Https://skia.org/user/download.

Need to use Git. Depot_tools is very full. There's everything.

We have previously compiled CEF and have voluntarily downloaded depot_tools. In E:\sources\CEF\2526\depot_tools, set to path:

set path=E:\sources\CEF\2526\depot_tools;%path%

Then use git to download Skia:

git clone https://skia.googlesource.com/skia.git

Then execute the following command:

cd %SKIA_CHECKOUT_DIR%SET "GYP_GENERATORS=ninja,msvs"  //告诉GYP。产生ninja构建文件和msvs构建文件python bin/sync-and-gyp             SET "GYP_GENERATORS="

After the above command is complete, the ninja-based build file is here: E:\sources\skia\out\Release (Debug) \build.ninja. The solution based on VS2013 is here: E:\sources\skia\out\skia.sln.

I choose to compile the release version number.

The "most" target is compiled by default. Most.ninja here: E:\sources\skia\out\Release\obj\gyp, which specifies the compilation skia_lib and the DM, SampleApp, HelloWorld and other modules.

Compile commands such as the following:

cd out\Releaseninja

Compiled into the effects module, something went wrong. Said:

Ninja:build Stopped:subcommand failed.

Add a number of references and then:

ninja -v > skia_build.log

Research Skia_build.log, find error messages such as the following:

Error C2220 is due to all warnings as errors, compile-time with the/WX tag. and warning C4819. MSDN says "C4819" occurs when an ANSI source file is compiled on a system that has a code page that cannot represent all characters in a file.

Remember before compiling CEF (refer to windows to compile CEF from source code) said to set the system locale to English, and then try again.

(⊙o⊙) ..., really.

After compiling, lib files and exe files are all under the E:\sources\skia\out\Release folder. There are so some Skia libraries, see:

Try executing the HelloWorld.exe (under the E:\sources\skia\out\Release folder). Effects such as:

Well, yes, I can move on.

Next time I will combine Ppapi and Skia to try.
