上一篇部落格《mingw(gcc)編譯openjpeg》講了如何用gcc編譯openjpeg,但我目前只會在64位平臺下生成64位目的碼，如果需要在64位平臺生成32位目的碼怎麼辦？我還沒有找到不修改CMakeList.txt的情況下在Windows 64位平臺用gcc生成32位程式碼的辦法（待研究），因為我的除錯環境還是喜歡用VS2015所以我決定還是用VS2015再把openjpeg編譯一遍，而且可以編譯32和64位程式碼，方法比較笨，但總算有效，以後再研究更好的辦法。
下面分別說明在win7 x64平臺下編譯32位和64位程式碼的過程

編譯環境

作者使用的作業系統平臺是win7 x64, 編譯器是目前最新的vs2015,cmake版本是3.1.0，準備好以上環境就可以開始程式碼編譯了。

先將原始碼包解壓到本地硬碟
D:\os.package\cpp\openjpeg\openjpeg-version.2.1
建立build目錄openjpeg-version.2.1.prj：

    D:\os.package\cpp\openjpeg>rmdir openjpeg-version.2.1.prj /s/q
    D:\os.package\cpp\openjpeg>mkdir openjpeg-version.2.1.prj
    D:\os.package\cpp\openjpeg>cd openjpeg-version.2.1.prj
    D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>

win 7 x64下編譯32位openjpeg

安裝好VS2015後在命令列下執行set顯示環境變數，會有如下圖紅圈所示的VS140COMNTOOLS變數

這裡寫圖片描述

然後在命令列執行

    D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>”%VS140COMNTOOLS%vsvars32.bat”
    來設定VC的命令列編譯環境。

然後執行cmake來生成makefile檔案

    D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>cmake -G “NMake Makefiles” -

在上面的執行cmake建立makefile時，定義了幾個引數，含義如下：
-G “NMake Makefiles”
生成NMake 格式的Makefiles ,nmake是msvc的命令列編譯工具
-DBUILD_SHARED_LIBS=OFF
指定建立靜態連結庫.lib，預設是ON,生成dll

    openjpeg提供的CMakeList.txt不能同時建立靜態庫和動態庫，所以你既想要靜態庫，又想到動態庫的時候，就得修改這個引數，編譯兩次。
    當生成動態庫的時候，還可以參加引數 -DCMAKE_GNUtoMS=ON 生成MSVC格式的匯入庫(import library .lib檔案)。這樣MSVC就可以直接使用GCC編譯的動態庫了。參見我之前的部落格《cmake:讓mingw(gcc)生成MSVC可用的dll(.lib)》

-DCMAKE_BUILD_TYPE=RELEASE
就是生成RELEASE，這個引數即使不定義，預設也是生成 RELEASE版本

CMAKE_INSTALL_PREFIX=j:/openjpeg-windows-vc-x86
這個引數指定在執行make install時的安裝路徑。如果不指定預設是安裝到”C:/Program Files (x86)/OPENJPEG”。

然後執行nmake

    D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>nmake

然後執行nmake install

然後執行nmake install ,就會將生成的二進位制檔案自動複製到前面CMAKE_INSTALL_PREFIX指定的J:\openjpeg-windows-vc-x86資料夾下，分為bin\include\lib三個子目錄。

win 7 x64下編譯64位openjpeg

上面的步驟執行下來，nmake生成的預設就是x86(32位)目的碼，因為對cmake nmake瞭解不夠，現在還不知道如何在這個過程中指定生成64程式碼，所以生成64位程式碼我用了另外一個過程。

    不要忘記了，在編譯之前一定也要像上面的步驟一樣，先執行”%VS140COMNTOOLS%vsvars32.bat”來設定VC的命令列編譯環境哦

清理掉上面過程的檔案，重新建立build資料夾（openjpeg-version.2.1.prj）
