让VC助手在外部文件变化时自动parse

我们的工程使用notepad++挂载protobuf的protoc代码生成器, 每次生成后, 助手都要手动parse一次, 很麻烦. 研究了下VC助手的选项, 按下图配置即可静默刷新文件

OpenGL混合的在线模拟器, 等了10年的工具…

即便是老外的教科书也是晦涩的,不如几行js来的爽快

VC工程的命令行编译法

我使用的是VS2010, 老版本的未测

call "c:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat"
cd 你的工程sln目录

MSBuild “你的工程.sln” /t:Build /p:Configuration=Release /maxcpucount:4

解释: 首先调用VC上下文建立批处理, 转到你的sln目录,保证工作目录正确, /maxcpucount是并行编译, 根据你的需求配置即可

使用HG(Mercurial)做分布式代码管理的一些经验

距离第一次使用HG已经由2,3年了。从第一次将HG用于自己的项目，用U盘同步代码. 到现在将HG应用于linux, 版本差异发布, 项目内部多人的分布式开发，已经感觉非常熟练。

我们的项目的客户端和服务器均由C++开发，由于HG设计的理念是1个工程对应1个库，因此我们的客户端和服务器是分开的两个HG代码库。这种思想和SVN管理的代码有很大不同。SVN时代的游戏工程大多是这样安排目录的：

common <-客户端和服务器共享的库

client<-客户端的代码

server<-服务器的代码

通过SVN强大的权限控制给不同的前后端赋予权限，前后端程序将获得不同的目录组合。SVN下的这种工程组织方法能很好的解决单一语言跨工程的代码，协议共享问题。虽然现在各种Erlang，Java的服务器语言与as3,lua的不同客户端脚本语言混杂的时代已经无所谓这种老式设计思想。但是对于我们纯C++的手游来说，还是必须面对分布式代码管理工具下的代码跨库共享问题。

我就这个问题与多年前被我推荐过HG的朋友讨论起来，他们也存在我们这个问题，但是他们的解决方法就是每个工程一个库。然后被我问到：“同步一次代码，一次次的打开不同的库（他们客户端+服务器一共6到7个HG代码库），进行同步，完成后，还要反向pull，不累啊？”，朋友回答：“习惯就好”

随后，我也翻查了git对多项目的支持。得到的答案也是跟HG一样的，这类分布式代码管理工具本身的设计理念只有账号，而无权限，本身就是基于开源代码精神设计的工具，如果分了权限，岂不是违背开源精神（这是我想的）。因此如果想管理多个项目代码，要么多库，要么合库。

luabind 0.9.1在boost 1.49+和gcc-4.6.3以上版本的编译问题处理

将boost更新到1.53时, 发现luabind死活编译不过, 报错如下

error: missing binary operator before token "("

根据老外的描述, boost中的BOOST_PP_ITERATION_FLAGS从1.49版本后发生了一些变化.

在git找到一个patch, 链接在此

以下简单描述

修改call_function.hpp, call_member.hpp及wrapper_base.hpp

去掉#elif BOOST_PP_ITERATION_FLAGS() == 1

更换为

#else

#if BOOST_PP_ITERATION_FLAGS() == 1

然后在源码底部加一个#endif即可

Qt应用程序使用图形解码无法显示的问题

最近发现一个Qt写的切图软件, 导入PNG图片可以显示, 而JPEG图片无法显示. 开发机正常. Google了一下, 发现Qt通过外部插件机制支持各种扩展功能.

在启动前, 添加如下代码:

QApplication qapp(argc, argv);

qapp.addLibraryPath(QCoreApplication::applicationDirPath()+"/plugins");

将QT开发目录下: Qt\4.8.2\plugins\拷贝到Qt的exe目录即可

Cygwin环境下使用Android NDK r8e编译boost 1.53

这里不能不说Google确实搜了1天都没解决问题, baidu第一个就解决了...

cygwin参考这里

http://my.oschina.net/tonywolf/blog/49214

简单的说

1.下载cygwin的网络安装包(第一次安装只能这样)

2. 选择靠前一点的网站进行下载( 下好的包可以留着, 下次安装直接从文件夹中选择就可以安装)

cygwin下使用NDK编译boost参考这里

http://blog.sina.com.cn/s/blog_a6946c8a01016aot.html

细节注意:

1. boost官网下载boost_1_53_0.tar.bz2, 解压放在android-ndk-r8e/sources下

2. 生成boost编译工具: 在boost目录下运行 ./bootstrap.sh 或者 bootstrap.bat 生成 b2

3. 修改 boost/tools/build/v2/user-config.jam 内容修改如下

import os ;

if [ os.name ] = CYGWIN || [ os.name ] = NT {

androidPlatform = windows ;

else if [ os.name ] = LINUX {

androidPlatform = linux-x86_64 ;

else if [ os.name ] = MACOSX {

androidPlatform = darwin-x86 ;

modules.poke : NO_BZIP2 : 1 ;

ANDROID_NDK = ../.. ;

using gcc : android4.6 : $(ANDROID_NDK)/toolchains/arm-linux-androideabi-4.6/prebuilt/$(androidPlatform)/bin/arm-linux-androideabi-g++ :

<archiver>$(ANDROID_NDK)/toolchains/arm-linux-androideabi-4.6/prebuilt/$(androidPlatform)/bin/arm-linux-androideabi-ar

<ranlib>$(ANDROID_NDK)/toolchains/arm-linux-androideabi-4.6/prebuilt/$(androidPlatform)/bin/arm-linux-androideabi-ranlib

<compileflags>--sysroot=$(ANDROID_NDK)/platforms/android-9/arch-arm

<compileflags>-I$(ANDROID_NDK)/sources/cxx-stl/gnu-libstdc++/4.6/include

<compileflags>-I$(ANDROID_NDK)/sources/cxx-stl/gnu-libstdc++/4.6/libs/armeabi/include

<compileflags>-DNDEBUG

<compileflags>-D__GLIBC__

<compileflags>-DBOOST_FILESYSTEM_VERSION=3

<compileflags>-lstdc++

<compileflags>-lgnustl_shared

<compileflags>-mthumb

<compileflags>-fno-strict-aliasing

<compileflags>-std=gnu++11

<compileflags>-O2

4. 为了安全起见, 我打了个BoostForAndriod上的补丁: 手动修改下就好了

5. 命令行编译:

./b2 --without-python --without-mpi --without-serialization toolset=gcc-android4.6 link=static runtime-link=static target-os=linux --stagedir=android

使用编译完成的boost库

1. 将编译boost_1_53_0\android\lib\ 下的.a库及boost_1_53_0\boost\下的头文件拷贝出来放在工程的boost4android目录下

2. 在boost4android目录下,创建Android.mk, 内容如下

可以根据自己的需要调整以上包含

3. 在应用程序的Android.mk中添加

LOCAL_WHOLE_STATIC_LIBRARIES += boost_system
LOCAL_WHOLE_STATIC_LIBRARIES += boost_filesystem
LOCAL_WHOLE_STATIC_LIBRARIES += boost_thread

用多少, 包多少

添加异常支持 LOCAL_CPPFLAGS += –fexceptions

添加模块引用

$(call import-module,boost4android)

Google Protocolbuf 文本格式的解析

protobuf就是为懒人而造的工具, 啥协议, 啥配置文件, 统统定义proto, 解析就ok, 非常方便

文本格式的解析错误不能使用捕获错误来获取, 因此,我们需要使用自定义的错误收集器进行收集, 看代码:

#include <google/protobuf/text_format.h>

#include <google/protobuf/io/zero_copy_stream_impl_lite.h>

#include <google/protobuf/io/tokenizer.h>

class PBTextErrorCollector : public google::protobuf::io::ErrorCollector

public:

    PBTextErrorCollector( const std::string& FileName )

        : mFileName( FileName )

    virtual void AddError(int line, int column, const string& message)

        CCLog("%s(%d:%d) %s ", mFileName.c_str(), line, column, message.c_str() );

    virtual void AddWarning(int line, int column, const string& message)

        CCLog("%s(%d:%d) %s ", mFileName.c_str(), line, column, message.c_str() );

private:

    std::string mFileName;

};

解析代码

google::protobuf::TextFormat::Parser P;

    P.RecordErrorsTo( &PEC );

    P.Parse( &AIS, &AF );

另外: 文本格式的注释使用unix shell风格: 以#开头

下面是我的文本格式的配置文件
