VS2015编译openjpeg(32/64位)

版权声明：本文为博主原创文章，转载请注明源地址。 https://cloud.tencent.com/developer/article/1433778

上一篇博客《mingw(gcc)编译openjpeg》讲了如何用gcc编译openjpeg,但我目前只会在64位平台下生成64位目标代码，如果需要在64位平台生成32位目标代码怎么办？我还没有找到不修改CMakeList.txt的情况下在Windows 64位平台用gcc生成32位代码的办法（待研究），因为我的调试环境还是喜欢用VS2015所以我决定还是用VS2015再把openjpeg编译一遍，而且可以编译32和64位代码，方法比较笨，但总算有效，以后再研究更好的办法。

下面分别说明在win7 x64平台下编译32位和64位代码的过程

编译环境

作者使用的操作系统平台是win7 x64, 编译器是目前最新的vs2015,cmake版本是3.1.0，准备好以上环境就可以开始代码编译了。

先将源码包解压到本地硬盘

D:\os.package\cpp\openjpeg\openjpeg-version.2.1

创建build目录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下编译32位openjpeg

安装好VS2015后在命令行下执行set显示环境变量，会有如下图红圈所示的VS140COMNTOOLS变量

然后在命令行执行

D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>”%VS140COMNTOOLS%vsvars32.bat” 来设置VC的命令行编译环境。

然后执行cmake来生成makefile文件

D:\os.package\cpp\openjpeg\openjpeg-version.2.1.prj>cmake -G “NMake Makefiles” - DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=j:/openjpeg-windows-vc-x86 -DCMAKE _BUILD_TYPE=RELEASE ..\openjpeg-version.2.1 – The C compiler identification is MSVC 19.0.23026.0 – Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/cl.exe – Check for working C compiler: C:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/bin/cl.exe – works – Detecting C compiler ABI info – Detecting C compiler ABI info - done – Check if the system is big endian – Searching 16 bit integer – Looking for sys/types.h – Looking for sys/types.h - found – Looking for stdint.h – Looking for stdint.h - found – Looking for stddef.h – Looking for stddef.h - found – Check size of unsigned short – Check size of unsigned short - done – Using unsigned short – Check if the system is big endian - little endian – Looking for string.h – Looking for string.h - found – Looking for memory.h – Looking for memory.h - found – Looking for stdlib.h – Looking for stdlib.h - found – Looking for stdio.h – Looking for stdio.h - found – Looking for math.h – Looking for math.h - found – Looking for float.h – Looking for float.h - found – Looking for time.h – Looking for time.h - found – Looking for stdarg.h – Looking for stdarg.h - found – Looking for ctype.h – Looking for ctype.h - found – Looking for assert.h – Looking for assert.h - found – Looking for stdint.h – Looking for stdint.h - found – Looking for inttypes.h – Looking for inttypes.h - found – Looking for strings.h – Looking for strings.h - not found – Looking for sys/stat.h – Looking for sys/stat.h - found – Looking for unistd.h – Looking for unistd.h - not found – Checking for 64-bit off_t – Checking for 64-bit off_t - not present – Checking for fseeko/ftello – Checking for fseeko/ftello - not found – Large File support - not found – Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR) – Z lib not found, activate BUILD_THIRDPARTY if you want build it (necessary to build libPNG) – Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR) – TIFF lib not found, activate BUILD_THIRDPARTY if you want build it – Could NOT find LCMS2 (missing: LCMS2_LIBRARY LCMS2_INCLUDE_DIR) – Could NOT find LCMS (missing: LCMS_LIBRARY LCMS_INCLUDE_DIR) – LCMS2 or LCMS lib not found, activate BUILD_THIRDPARTY if you want build it – Configuring done – Generating done – Build files have been written to: D:/os.package/cpp/openjpeg/openjpeg-version.2.1.prj

在上面的执行cmake创建makefile时，定义了几个参数，含义如下：

-G “NMake Makefiles”

生成NMake 格式的Makefiles ,nmake是msvc的命令行编译工具

-DBUILD_SHARED_LIBS=OFF

指定创建静态链接库.lib，默认是ON,生成dll

openjpeg提供的CMakeList.txt不能同时创建静态库和动态库，所以你既想要静态库，又想到动态库的时候，就得修改这个参数，编译两次。undefined 当生成动态库的时候，还可以参加参数 -DCMAKE_GNUtoMS=ON 生成MSVC格式的导入库(import library .lib文件)。这样MSVC就可以直接使用GCC编译的动态库了。参见我之前的博客《cmake:让mingw(gcc)生成MSVC可用的dll(.lib)》

-DCMAKE_BUILD_TYPE=RELEASE

就是生成RELEASE，这个参数即使不定义，默认也是生成 RELEASE版本

CMAKE_INSTALL_PREFIX=j:/openjpeg-windows-vc-x86

这个参数指定在执行make install时的安装路径。如果不指定默认是安装到”C:/Program Files (x86)/OPENJPEG”。

然后执行nmake

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

然后执行nmake install

然后执行nmake install ,就会将生成的二进制文件自动复制到前面CMAKE_INSTALL_PREFIX指定的J:\openjpeg-windows-vc-x86文件夹下，分为bin\include\lib三个子目录。

win 7 x64下编译64位openjpeg

上面的步骤执行下来，nmake生成的默认就是x86(32位)目标代码，因为对cmake nmake了解不够，现在还不知道如何在这个过程中指定生成64代码，所以生成64位代码我用了另外一个过程。

不要忘记了，在编译之前一定也要像上面的步骤一样，先执行”%VS140COMNTOOLS%vsvars32.bat”来设置VC的命令行编译环境哦

清理掉上面过程的文件，重新创建build文件夹（openjpeg-version.2.1.prj）

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

编译结束，所有的目标文件都在openjpeg-version.2.1.prj/bin/Release下。使用devenv编译sln工程没有install过程，你得手工把目标文件复制到你需要的位置。

在调用cmake生成OPEN.sln时如果 BUILD_SHARED_LIBS设为ON，就会生成openjp2.dll和导入库(import library)openjp2.lib

说话，我觉得编译32位和64位目标代码要用不同的办法，还是挺麻烦的，对于cmake交叉编译，目前还没有完全搞明白，如果哪位朋友有办法，不吝赐教啊。
