C++ 编译libjpeg

Compiling libjpeg

提问by NiVeR

Is there anyone who succeed to include libjpeg in some compiler? I tried everything: Dev C++, VS10, CodeBlocks, copy the headers and the lib by hand, add with the linker but nothing. Right now I am really confisued as there is not an official guide on how to compile it in any compiler. I would be really happy if someone could provide a tutorial on how the library can be compiled in any compiler. Thank you in advance.

有没有人成功地将 libjpeg 包含在某个编译器中？我尝试了所有方法：Dev C++、VS10、CodeBlocks，手动复制头文件和库，添加链接器但什么也没有。现在我真的很困惑，因为没有关于如何在任何编译器中编译它的官方指南。如果有人可以提供有关如何在任何编译器中编译库的教程，我会非常高兴。先感谢您。

Here is how I've built libjpeg using MinGW on Windows :

这是我在 Windows 上使用 MinGW 构建 libjpeg 的方法：

1. Get MinGW with MSYS

1. 使用 MSYS 获取 MinGW

I've got a copy from http://sourceforge.net/projects/mingw/. Quoting from www.mingw.org :

我有一份来自http://sourceforge.net/projects/mingw/的副本。引自 www.mingw.org ：

MSYS is a collection of GNU utilities such as bash, make, gawk and grep to allow building of applications and programs which depend on traditionally UNIX tools to be present.

MSYS 是 GNU 实用程序的集合，例如 bash、make、gawk 和 grep，用于构建依赖于传统 UNIX 工具的应用程序和程序。

We will need it to run the configurescript that comes with libjpeg sources.

我们将需要它来运行configurelibjpeg 源代码附带的脚本。

2. Get libjpeg sources

2. 获取 libjpeg 源码

From http://www.ijg.org/, take the Unix format package (the Windows one won't work with this procedure). I took the jpeg_8dversion.

从http://www.ijg.org/获取 Unix 格式的软件包（Windows 格式的软件包不适用于此过程）。我拿了jpeg_8d版本。

3. Prepare a building directory

3.准备一个构建目录

I've made a temporary directory named tmpin D:\, but you could choose whatever suits your needs. The thing that matters is the name of paths in MSYS. As it brings some * Unixity* to Windows, paths cannot be used in their original form. In a nutshell:

我已经创建了一个名为tmpin的临时目录D:\，但您可以选择适合您需要的任何目录。重要的是 MSYS 中路径的名称。由于它为Windows带来了一些 * Unixity*，路径不能以其原始形式使用。简而言之：

C:\path\to\filebecomes /c/path/to/filein MSYS land, an so D:\tmpbecomes /d/tmp.

C:\path\to\file成为 /c/path/to/file在MSYS土地，一个这样 D:\tmp变成 /d/tmp。

Decompress the libjpeg sources in D:\tmp, so you have a jpeg-8ddirectory in there.

解压 中的 libjpeg 源代码D:\tmp，这样你就有了一个jpeg-8d目录。

Create a jpeg-builddirectory inside D:\tmp, it will hold the built library.

jpeg-build在里面创建一个目录D:\tmp，它将保存构建的库。

Now everything is ready for the build.

现在一切都已准备好进行构建。

4. ./configure, make, make install

4../configure, make, make install

That is the mantra of building in Unix land. An option should be added to redirect the install process to D:\tmp\jpeg-build.

这是在 Unix 土地上建设的口头禅。应该添加一个选项以将安装过程重定向到D:\tmp\jpeg-build.

Run the following commands in an MSYS shell (also named MinGW shell in Windows start menu):

在 MSYS shell（在 Windows 开始菜单中也称为 MinGW shell）中运行以下命令：

cd /d/tmp/jpeg-8d
./configure --prefix=/d/tmp/jpeg-build
make
make install

As an additional step, you can run make testfor safety.

作为一个额外的步骤，你可以make test为了安全而跑步。

These commands will build both static and shared versions of libjpeg.

这些命令将构建 libjpeg 的静态和共享版本。

5. Take the goods, delete the temporaries

5.拿货，删除临时工

If everything runs fine, you can delete the D:\tmp\jpeg-8ddirectory, but keep the jpeg-buildone. It contains:

如果一切正常，您可以删除该D:\tmp\jpeg-8d目录，但保留该目录jpeg-build。它包含了：

• an includedirectory, containing libjpeg headers. You can move them to your compiler's headers directory.
• a libdirectory, with .afile to pass to the linker. You can move them to your compiler's library directory.
• a bindirectory, holding the libjpeg shared library libjpeg-8.dlland jpeg tools.
• a sharedirectory, containing manpages for the jpeg tools.

• 一个include目录，包含 libjpeg 头文件。您可以将它们移动到编译器的头文件目录。
• 一个lib目录，包含.a要传递给链接器的文件。您可以将它们移动到编译器的库目录中。
• 一个bin目录，包含 libjpeg 共享库libjpeg-8.dll和 jpeg 工具。
• 一个share目录，包含manjpeg 工具的页面。

You can now build your program and link it against libjpeg by indicating the right include and library paths.

您现在可以通过指明正确的包含和库路径来构建您的程序并将其链接到 libjpeg。

You can find many details about the libjpeg building and installation process in install.txtinside the source package.

您可以install.txt在源代码包中找到有关 libjpeg 构建和安装过程的许多详细信息。

I hope this will be useful.

我希望这会很有用。

To compile libjpeg9 in Visual Studio 2012, here are the steps (after unzipping the archive file):

要libjpeg在 Visual Studio 2012 中编译9，步骤如下（解压存档文件后）：

1. Download the file WIN32.MAK(for example, from http://www.bvbcode.com/code/f2kivdrh-395674-down), and place a copy in the root source code directory (possibly C:\jpeg-9, but it depends where you unzipped it). I will refer to this directory as %jpegsrc%from now on. Having this file is important; otherwise step 3 will produce an error.

2. In the Visual Studio command prompt, open to %jpegsrc%:

   cd %jpegsrc%

3. At the same command prompt, execute the following:

   NMAKE /f makefile.vc setup-v10

   This will create two Visual Studio 2010 solutions in %jpegsrc%: jpeg.slnand apps.sln.

4. Open each solution in Visual Studio 2012. Each one will prompt you to update all the projects to 2012 format. Click on “Update.” One time I did it, the prompt did not appear. In case that happens, right-click on the jpegsolution in the Solution Explorer, and choose “Update VC++ projects...,” which will produce the same prompt.

5. Save and build each solution as normal. (You have to build the jpeg.slnsolution before apps.sln, since the latter depends on the former.)

1. 下载该文件WIN32.MAK（例如，从http://www.bvbcode.com/code/f2kivdrh-395674-down），并在源代码根目录中放置一个副本（可能是C:\jpeg-9，但这取决于您将其解压缩的位置）。%jpegsrc%从现在开始，我将参考这个目录。拥有这个文件很重要；否则步骤 3 将产生错误。

2. 在 Visual Studio 命令提示符中，打开到%jpegsrc%：

   cd %jpegsrc%

3. 在相同的命令提示符下，执行以下命令：

   NMAKE /f makefile.vc setup-v10

   这将在%jpegsrc%:jpeg.sln和apps.sln.

4. 在 Visual Studio 2012 中打开每个解决方案。每个解决方案都会提示您将所有项目更新为 2012 格式。点击“更新”。我做了一次，提示没有出现。如果发生这种情况，请在jpeg解决方案资源管理器中右键单击解决方案，然后选择“更新 VC++ 项目...”，这将产生相同的提示。

5. 像往常一样保存和构建每个解决方案。（您必须在jpeg.sln之前构建解决方案apps.sln，因为后者取决于前者。）

Note: this process should work correctly in Visual Studio 2010, without the updating, but I have not tested it.

注意：此过程在 Visual Studio 2010 中应该可以正常工作，无需更新，但我尚未对其进行测试。

Update:This method still works in Visual Studio 2015 for libjpeg-9a.

更新：此方法在 Visual Studio 2015 for libjpeg-9a.

It is really simple to build jpeg.lib with VS10.

用 VS10 构建 jpeg.lib 真的很简单。

First, download the libjpeg source code in zip format. At the time I'm writing this you can find it here.

首先，下载 zip 格式的 libjpeg 源代码。在我写这篇文章的时候，你可以在这里找到它。

Then extract the contents of the zip file to your disk.

然后将 zip 文件的内容解压缩到您的磁盘。

Then open a VS2010 command prompt shell (or call vcvarsall.bat on any command prompt window), cd to the jpeg source directory (jpeg-8d in the download referenced above) and type the following:

然后打开一个 VS2010 命令提示符 shell（或在任何命令提示符窗口中调用 vcvarsall.bat），cd 到 jpeg 源目录（上面引用的下载中的 jpeg-8d）并键入以下内容：

nmake -f makefile.win setup-v10

This will generate two VS2010 solutions, and a bunch of project files. The solutions are:

这将生成两个 VS2010 解决方案和一堆项目文件。解决方法是：

• jpeg.sln, which builds jpeg.lib
• apps.sln, which builds the sample applications.

• jpeg.sln, 建立 jpeg.lib
• apps.sln，构建示例应用程序。

Good luck!

祝你好运！

If you don't happen to have Visual Studio 2010 installed, here is what works on Visual Studio 2017:

如果您没有安装 Visual Studio 2010，以下是适用于 Visual Studio 2017 的内容：

Basic / Common steps:

基本/常见步骤：

1. Download the latest version of libjpeg from: http://www.ijg.org/(zip version) and extract it to a folder
2. Open the "Developer Command Prompt for VS2017"
3. Change directory (cd) to where you extracted the library source

1. 从以下位置下载最新版本的 libjpeg：http://www.ijg.org/ （zip 版本）并将其解压缩到一个文件夹中
2. 打开“VS2017的开发人员命令提示符”
3. 将目录 ( cd)更改为提取库源的位置

VS 2017 Approach:

VS 2017 方法：

1. Include the Windows SDK v7.1A directory(required for Win32.Mak by nmake later on) by running: set INCLUDE=%INCLUDE%;c:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include

2. Run nmake /f makefile.win setup-v15(note the v15 for VS2017 here)

4. 通过运行包含 Windows SDK v7.1A 目录（稍后 nmake 需要 Win32.Mak）：set INCLUDE=%INCLUDE%;c:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include

5. 运行nmake /f makefile.win setup-v15（注意这里是 VS2017 的 v15）

From here on follow what @AthanasiusOfAlex explained to upgrade the Visual Studio 2010 solution to the Visual Studio version you are running. If you want the Debug configuration, follow what @SteveEng explained.

从这里开始，按照@AthanasiusOfAlex 的解释将 Visual Studio 2010 解决方案升级到您正在运行的 Visual Studio 版本。如果您需要调试配置，请按照@SteveEng 的说明进行操作。

Errors you might stumble across:

您可能会遇到的错误：

• If nmakefails and tells you it doesn't know how to make jconfig.h, manually rename the file jconfig.vcto jconfig.h
• If nmakefails and tells you Win32.Mak cannot be found, manually copy it from the SDK dir mentioned in step #4 to the libjpeg source directory. If you don't happen to have that SDK version installed, download the file from a trustworthy resource.
• If nmakefails and tells you it doesn't know how to make setup-v15, trial and error your way through starting with setup-v10, setup-v11, etc... These are VS versions and one of them should work as long as you have any VS version later than VS 2008 installed.

• 如果nmake失败并告诉您它不知道如何制作 jconfig.h，请手动将文件重命名jconfig.vc为jconfig.h
• 如果nmake失败并告诉您找不到 Win32.Mak，请手动将其从步骤 #4 中提到的 SDK 目录复制到 libjpeg 源目录。如果您没有安装该 SDK 版本，请从可信赖的资源下载该文件。
• 如果nmake失败并告诉您它不知道如何setup-v15通过从setup-v10,开始的方式进行尝试和错误setup-v11...安装。

Hope this helps people going through similar pain with this.

希望这可以帮助人们经历类似的痛苦。
