libCurl x64 在 Visual Studio 2013 (x64) 中的构建问题（Visual Studio & CMake）

Question

我正在尝试在Windows 8.1 x64上构建libCurl x64，但是遇到了链接器错误。我需要这样做，因为我需要创建一个64位调试版本的库，以便跟踪一些奇怪的FTP相关协议问题。基本的错误输出（为简洁起见已削减）如下：

请帮忙 - 我在论坛和stackoverflow上搜索了类似的内容，但没有找到。我能够成功构建x86（win32）模式，但是当我以x64为目标时，我遇到了链接错误。

步骤1： 下载最新版本的CMake 2.8.12.2并更新Windows PATH环境变量（在我的情况下，我使用MINMGW32 bash shell提示符，但如果我使用本机Visual Studio 2013 x64 shell运行cmake也会出现完全相同的链接问题） $ export PATH=$PATH:/c/Program\ Files\ (x86)/CMake\ 2.8/bin

验证Windows上Cmake的路径和版本 $ cmake --version cmake version 2.8.12.2

步骤2： 将curl-7.35.0提取到文件夹c：\temp\curl-7.35.0中，并创建一个并行文件夹“c：\temp\curl-7.35.0 \build”。

步骤3： 更改到构建文件夹并运行Cmake，将Visual Studio 12作为所需的Visual Studio Solution / project组合进行定位 $ cmake -G "Visual Studio 12" ../curl-7.35.0

这会产生大量输出，但它确实创建了一个可工作的Visual Studio解决方案，其目标是X86机器类型。

步骤4： 在Visual Studio中，使用配置管理器将目标类型更改为x64（我不得不选择一个新平台，我选择了X64并从Win32复制了设置）。这是一个非常简单明了的步骤，用于针对X64机器目标，为了避免混淆，我没有在这里包含详细的步骤。

步骤5： 从Visual Studio 2013中选择解决方案并重新构建所有内容，上面的输出将随之而来。

旁注：虽然我现在不需要SSL，但知道如何告诉CMake LIBSSL事物的位置会很好（我从http://www.confusedbycode.com/curl/下载了一个预构建库包（包括SSL和其他库的32位和64位版本），但这些是发布模式，我需要能够调试libCurl以查看我遇到的一些奇怪问题。我不擅长配置CMake，但它似乎是一个非常有前途的工具，适用于那些针对多个平台但更喜欢在Windows上开发的人。它肯定比gnu autotools容易。

在 Visual Studio 中，使用配置管理器将目标类型更改为 x64。在这种情况下，您需要使用“Visual Studio 12 Win64”生成器。 - user2288008

从第4步开始，阅读我的完整帖子，您可以看到我已经尝试过了，但出现了问题：致命错误LNK1112：模块机器类型“x64”与目标机器类型“X86”冲突。 - johnco3

Visual Studio 12和Visual Studio 12 Win64是不同的生成器。据我所知，您无法使用Visual Studio 12生成项目并切换到x64。请尝试使用cmake -G "Visual Studio 12 Win64" ../curl-7.35.0。 - user2288008

干得好，那真的起作用了，我从来没有意识到我可以将"Win64"字符串附加到生成器字符串上。谢谢 - 非常有用，现在下一个挑战将是解决OPENSSL_LIBRARIES OPENSSL_INCLUDE_DIR - 但我怀疑这不会很困难（尽管我需要确保这些库也在Win64中构建）。再次感谢 - johnco3

Answer 1

在干净的x64 / Win 8.1 / VS2013环境中构建64位libcurl的技巧是，首先使用"amd64"参数运行Visual Studio vcvars.bat批处理文件。这将正确设置制作环境。

然后按照winbuild\BUILD.WINDOWS.txt中所述运行“nmake…”命令即可。

Answer 2

看起来CMake生成的解决方案文件没有将X64作为潜在目标。我在这里找到了一个问题的微小变体。

这里输入链接描述

这是X64命令行选项的图片 - 如您所见，在我将配置管理器更改为使用X64后，

在进行这些更改后，项目最终链接成功，我能够生成库的调试版本。

你是如何告诉nmake进入winbuild并运行Makefile.vc的呢？ - NobleUplift

构建libCurl库（发布版和调试版）

（1）使用VS2015 x64本机工具命令提示符从extlibs/curl-7.44.0开始： （2）cd \Users\Johnc\main\extlibs\curl-7-44.0\winbuild （3）nmake /f Makefile.vc mode=dll VC=14 MACHINE=x64 GEN_PDB=yes （4）nmake /f Makefile.vc mode=dll VC=14 MACHINE=x64 DEBUG=yes GEN_PDB=yes - johnco3

抱歉，我的问题表述不够清晰。你是如何在Visual Studio中设置libcurl进行构建的？每次我尝试构建项目时，它都会失败并显示找不到../<某个文件夹>的错误信息。 - NobleUplift

Answer 3

我在使用命令行构建CURL时遇到了相同的问题（module machine type 'x64' conflicts with target machine type 'X86'），这是在文件夹“curl-7.40.0 \ winbuild”中按照“BUILD.WINDOWS.txt”中的描述。我使用了以下命令行：nmake / f Makefile.vc mode = dll ENABLE_WINSSL = no ENABLE_IDN = no GEN_PDB = yes ENABLE_SSPI = no MACHINE = x64 DEBUG = no。它指定“使用Visual Studio命令提示符Shell”，但是…还有更多：“Visual Studio 2005命令提示符”无法正常工作，“Visual Studio 2005 x64 Win64命令提示符”可以（用于64位）。对我来说，它适用于Visual Studio 2005，但他们说它只需要“Platform SDK”。

Answer 4

将此脚本放置在Curl的源目录中（我将其命名为winbuild.bat），如果您不需要curl项目与解决方案的其他部分一起编译，请运行它：

@ECHO OFF
CALL "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64\vcvars64.bat"
CD winbuild
nmake /f Makefile.vc mode=dll WITH_DEVEL=..\..\dll64 VC=12 WITH_SSL=dll GEN_PDB=yes MACHINE=X64
CD ..
EXIT /B 0
