按照官方的操作说明（https://bitbucket.org/chromiumembedded/cef/wiki/MasterBuildQuickStart.md#markdown-header-windows-setup）编译会出现不少问题
1、首先如果安装的是版本的（Python 3.0以上），在调用（create.bat）生成工程会有一个接口报错，编译会被阻塞
unicode("", "utf-8")这个函数在python 3.0版本已经被废除了，因此需要切换道python 2.7才能编译通过，在安装python 2.1以后需要重新配置python的系统路径，确保优先运行低版本的python
2、在编译skia的时候会遇到如下错误：
In file included from ../../cef/libcef/renderer/blink_glue.cc:12:

#include SK_USER_CONFIG_HEADER
^
<command line>(61,31): note: expanded from here
#define SK_USER_CONFIG_HEADER "../../skia/config/SkUserConfig.h"
查阅资料，主要原因是不同编译器查找头文件规则不同，修改SkTypes.h 191行
// IWYU pragma: begin_exports
#undef SK_USER_CONFIG_HEADER
#if defined (SK_USER_CONFIG_HEADER)
#include SK_USER_CONFIG_HEADER
#else
#include "include/config/SkUserConfig.h"
#endif
再编译时这个问题就消失了
3、出现SkDrawLooper is unsupported为问题
In file included from ../../cc/layers/recording_source.cc:13:
In file included from ../..\cc/layers/content_layer_client.h:11:
In file included from ../..\cc/paint/display_item_list.h:18:
In file included from ../..\cc/paint/discardable_image_map.h:19:
In file included from ../..\cc/paint/paint_flags.h:13:
../..\third_party/skia/include/core/SkDrawLooper.h(20,2): error: "SkDrawLooper is unsupported"
#error "SkDrawLooper is unsupported"
查看了skia的源码SkDrawLooper.h，明确写了不支持，不知道为什么还要include这个文件
/** \class SkDrawLooper
DEPRECATED: No longer supported in Skia.
*/
class SK_API SkDrawLooper : public SkFlattenable {
public:
把paint_flags.h中包含文件去掉
#include "third_party/skia/include/core/SkColorFilter.h"
//#include "third_party/skia/include/core/SkDrawLooper.h"
会出错
In file included from ../..\cc/paint/paint_filter.h:13:
../..\cc/paint/paint_flags.h(142,29): error: use of undeclared identifier 'SkDrawLooper'
ALWAYS_INLINE const sk_sp<SkDrawLooper>& getLooper() const {
^
../..\cc/paint/paint_flags.h(145,38): error: use of undeclared identifier 'SkDrawLooper'
ALWAYS_INLINE void setLooper(sk_sp<SkDrawLooper> looper) {
^
../..\cc/paint/paint_flags.h(187,9): error: use of undeclared identifier 'SkDrawLooper'
sk_sp<SkDrawLooper> draw_looper_;
^
../..\cc/paint/paint_flags.h(165,21): error: use of undeclared identifier 'SkDrawLooper'
if (const sk_sp<SkDrawLooper>& looper = getLooper())
看来还是调用这个类，只好修改SkDrawLooper.h,将报错内容注释掉
/*
#ifndef SK_SUPPORT_LEGACY_DRAWLOOPER
#error "SkDrawLooper is unsupported"
#endif
*/
这一块就可以编译通过，不过新的问题又来了
../../cc/paint/paint_shader.cc(463,47): error: no matching member function for call to 'makeShader'
cached_shader_ = image_.GetSkImage()->makeShader(
