編譯環(huán)境

操作平臺：win7 x64，編譯器是vs2010，cmake版本3.12.4，準(zhǔn)備好環(huán)境就可以開始代碼編譯。

注：CMake是一個跨平臺的安裝（[編譯]）工具，可以用簡單的語句來描述所有平臺的安裝(編譯過程)。他能夠輸出各種各樣的makefile或者project文件，能測試[編譯器]所支持的C++特性,類似UNIX下的automake。只是 CMake 的[組態(tài)檔]取名為 CMakeLists.txt。

編譯過程

1. 現(xiàn)將源碼解壓到本地硬盤
2. 創(chuàng)建build目錄：openjpeg-version.2.1.prj
3. 在build目錄下執(zhí)行
   "%VS100COMNTOOLS%vsvars32.bat"//配置環(huán)境變量
   cmake -G "Visual Studio 10 2010 Win64" -DBUILD_SHARED_LIBS:bool=on -DBUILD_THIRDPARTY:bool=on ..\openjpeg-version.2.1//生成project文件（vs為.sln文件）
4. 編譯：devenv OPENJPEG.sln /build "Release|x64"

注：

在上面的執(zhí)行cmake創(chuàng)建makefile時，定義了幾個參數(shù)，含義如下：
-G “Visual Studio 10 2010 Win64”
指定編譯器架構(gòu)
-DBUILD_SHARED_LIBS=ON
指定創(chuàng)建靜態(tài)鏈接庫.lib，默認(rèn)是ON,生成dll

此過程中出現(xiàn)error：

1. cmake不是內(nèi)部或外部命令
   解決：需要將cmake的exe路徑配置到環(huán)境變量，重啟cmd即可執(zhí)行
2. fatal error C1902: 程序數(shù)據(jù)庫管理器不匹配；請檢查安裝
   解決：找到vs安裝目錄C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\x86_amd64，其下mspdb100.dll、mspdbcore.dll和mspdbsrv.exe這個三個文件版本不一致，找到一個可以正常運(yùn)行VS的電腦，將其相應(yīng)目錄下的三個文件拷進(jìn)上述文件夾，問題解決。
