讓VC助手在外部文件變化時自動parse

我們的工程使用notepad++掛載protobuf的protoc代碼生成器, 每次生成后, 助手都要手動parse一次, 很麻煩. 研究了下VC助手的選項, 按下圖配置即可靜默刷新文件

OpenGL混合的在線模擬器, 等了10年的工具…

即便是老外的教科書也是晦澀的,不如幾行js來的爽快

VC工程的命令行編譯法

我使用的是VS2010, 老版本的未測

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

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

解釋: 首先調用VC上下文建立批處理, 轉到你的sln目錄,保證工作目錄正確, /maxcpucount是并行編譯, 根據你的需求配置即可

使用HG(Mercurial)做分布式代碼管理的一些經驗

距離第一次使用HG已經由2,3年了。從第一次將HG用于自己的項目，用U盤同步代碼. 到現在將HG應用于linux, 版本差異發布, 項目內部多人的分布式開發，已經感覺非常熟練。

我們的項目的客戶端和服務器均由C++開發，由于HG設計的理念是1個工程對應1個庫，因此我們的客戶端和服務器是分開的兩個HG代碼庫。這種思想和SVN管理的代碼有很大不同。SVN時代的游戲工程大多是這樣安排目錄的：

common <-客戶端和服務器共享的庫

client<-客戶端的代碼

server<-服務器的代碼

通過SVN強大的權限控制給不同的前后端賦予權限，前后端程序將獲得不同的目錄組合。SVN下的這種工程組織方法能很好的解決單一語言跨工程的代碼，協議共享問題。雖然現在各種Erlang，Java的服務器語言與as3,lua的不同客戶端腳本語言混雜的時代已經無所謂這種老式設計思想。但是對于我們純C++的手游來說，還是必須面對分布式代碼管理工具下的代碼跨庫共享問題。

我就這個問題與多年前被我推薦過HG的朋友討論起來，他們也存在我們這個問題，但是他們的解決方法就是每個工程一個庫。然后被我問到：“同步一次代碼，一次次的打開不同的庫（他們客戶端+服務器一共6到7個HG代碼庫），進行同步，完成后，還要反向pull，不累啊？”，朋友回答：“習慣就好”

隨后，我也翻查了git對多項目的支持。得到的答案也是跟HG一樣的，這類分布式代碼管理工具本身的設計理念只有賬號，而無權限，本身就是基于開源代碼精神設計的工具，如果分了權限，豈不是違背開源精神（這是我想的）。因此如果想管理多個項目代碼，要么多庫，要么合庫。

luabind 0.9.1在boost 1.49+和gcc-4.6.3以上版本的編譯問題處理

將boost更新到1.53時, 發現luabind死活編譯不過, 報錯如下

error: missing binary operator before token "("

根據老外的描述, boost中的BOOST_PP_ITERATION_FLAGS從1.49版本后發生了一些變化.

在git找到一個patch, 鏈接在此

以下簡單描述

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

去掉#elif BOOST_PP_ITERATION_FLAGS() == 1

更換為

#else

#if BOOST_PP_ITERATION_FLAGS() == 1

然后在源碼底部加一個#endif即可

Qt應用程序使用圖形解碼無法顯示的問題

最近發現一個Qt寫的切圖軟件, 導入PNG圖片可以顯示, 而JPEG圖片無法顯示. 開發機正常. Google了一下, 發現Qt通過外部插件機制支持各種擴展功能.

在啟動前, 添加如下代碼:

QApplication qapp(argc, argv);

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

將QT開發目錄下: Qt\4.8.2\plugins\拷貝到Qt的exe目錄即可

Cygwin環境下使用Android NDK r8e編譯boost 1.53

這里不能不說Google確實搜了1天都沒解決問題, baidu第一個就解決了...

cygwin參考這里

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

簡單的說

1.下載cygwin的網絡安裝包(第一次安裝只能這樣)

2. 選擇靠前一點的網站進行下載( 下好的包可以留著, 下次安裝直接從文件夾中選擇就可以安裝)

cygwin下使用NDK編譯boost參考這里

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

細節注意:

1. boost官網下載boost_1_53_0.tar.bz2, 解壓放在android-ndk-r8e/sources下

2. 生成boost編譯工具: 在boost目錄下運行 ./bootstrap.sh 或者 bootstrap.bat 生成 b2

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

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. 為了安全起見, 我打了個BoostForAndriod上的補丁: 手動修改下就好了

5. 命令行編譯:

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

使用編譯完成的boost庫

1. 將編譯boost_1_53_0\android\lib\ 下的.a庫及boost_1_53_0\boost\下的頭文件拷貝出來放在工程的boost4android目錄下

2. 在boost4android目錄下,創建Android.mk, 內容如下

可以根據自己的需要調整以上包含

3. 在應用程序的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

添加異常支持 LOCAL_CPPFLAGS += –fexceptions

添加模塊引用

Google Protocolbuf 文本格式的解析

protobuf就是為懶人而造的工具, 啥協議, 啥配置文件, 統統定義proto, 解析就ok, 非常方便

文本格式的解析錯誤不能使用捕獲錯誤來獲取, 因此,我們需要使用自定義的錯誤收集器進行收集, 看代碼:

#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;

};

解析代碼

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

    P.RecordErrorsTo( &PEC );

    P.Parse( &AIS, &AF );

另外: 文本格式的注釋使用unix shell風格: 以#開頭

下面是我的文本格式的配置文件
