1.下载cygwin,并安装如下项:
autobuild autoconf autogen automake ccrypt cmake gcc-g++ gdb httpd libGLw-devel libc++-devel libglut3 make mingw64-x86_64-SDL2 mingw64-x86_64-gcc-g++ mingw64-x86_64-speex mingw64-x86_64-zlib wget
2. 修改 includeasecef_build.h 文件
#if defined(_WIN32) #ifndef OS_WIN #define OS_WIN 1 #endif
改成:
#if defined(_WIN32) || defined(__CYGWIN__) #ifndef OS_WIN #define OS_WIN 1 #endif
3. 拷贝 cef_atomicops_x86_gcc.h 到 includeaseinternal,其内容如下:

4. 修改 libcef_dllasecef_logging.cc文件,注释掉该行
//typedef DWORD SystemErrorCode;
5. 将 libcef_dllwrappercef_byte_read_handler.cc 下面这行做如下修改:
// int64 offset_abs = _abs64(offset); int64 offset_abs = llabs(offset);
6. 编译
cd 到cef根目录 mkdir build && cd build cmake -DCMAKE_GENERATOR="Unix Makefiles" -DCMAKE_SYSTEM_NAME=CYGWIN -DPROJECT_ARCH=x86_64 -DCMAKE_BUILD_TYPE=Release ..
7. 编译后使用静态库时会出现new/delete找不到定义的情况,则将它们换成 malloc/free
