renderer.gua's Issues

Visual Studio 2015 支持

在这个 pull request 中，你建议把project file单独放到一个文件夹中。对应的lib的dll也要放过去吗？
因为要支持VS2015的话，就要重新编译源代码。所以就会有不同的 lib 和 dll。
经测试，官方最新的 build 是可以在VS2015下面用的。
能说下为什么用sdl1而不是sdl2吗？因为最新的build用的是sdl2。
我照着官方的迁移指南对windows.h做了些修改，你看看？https://github.com/happlebao/renderer.gua/blob/sdl2/src/window.h
你觉得那个null 的检查需不需要单独抽成一个函数？

觉得行的话我就开个 pull request。

我尝试用你的脚本安装SDL，失败了，于是用brew安装，以上是结果。
问题源头是g++吗？

g++ --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin15.2.0
Thread model: posix

BTW，我之前装过LLVM

lli --version
LLVM (http://llvm.org/):
LLVM version 3.8.0svn
DEBUG build with assertions.
Built Nov 11 2015 (23:25:56).
Default target: x86_64-apple-darwin15.2.0
Host CPU: has well

是否因为LLVM版本不匹配（llvm3.6.0 and llvm 3.8.0）？

Failed to build(windows10 vs2015 )

Split 没有判断字符串是否为空

split函数里 l.push_back(str.substr(start)) 没有判断为空的情况，有可能会加入一个空字符串
