整个过程用的是 vs2015命令提示工具
需要安装perl 下载地址添加链接描述 解压后 在 openssl-1.0.2e目录下创建develop这个文件夹 cd到 openssl-1.0.2e目录下
a.配置编译文件和模式 执行
perl Configure VC-WIN32 no-asm --prefixE:\curl\openssl-1.0.2e\developVC-WIN32标识windows 32位操作系统 64位用VC-WIN64A表示 若要使用debug版本请使用debug-VC-WIN64A或debug-VC-WIN32 no-asm 表示不用汇编 –prefixE:\curl\openssl-1.0.2e\develop 是设置安装目录 b.生成编译配置文件 若为Windows 64位系统执行
ms\do_win64a.bat若为Windows 32位系统执行
ms\do_ms.bat执行这一步之后在ms目录下会生成nt.mak和ntdll.mak两个编译配置文件 nt.mak 用于生成静态lib库 ntdll.mak 用于生成动态dll库 c.编译 静态库
nmake -f ms\nt.mak 动态库
nmake -f ms\ntdll.makd.测试 测试静态库 nmake -f ms\nt.mak test测试动态库 nmake -f ms\ntdll.mak test若最终显示 passed all tests 则说明生成的库正确 e.安装 安装静态库
nmake -f ms\nt.mak install安装动态库
nmake -f ms\ntdll.mak install编译安装完成后会在E:\curl\openssl-1.0.2e\develop目录下看到生成的相关文件夹 f.清楚上次编译 清除上次静态库的编译以便重新编译
nmake -f ms\nt.mak clean清除上次动态库的编译以便重新编译
nmake -f ms\ntdll.mak clean参考https://blog.csdn.net/mayue_web/article/details/83997969非常详细
2.编译zlib
a.下载源码 http://zlib.net/zlib-1.2.11.tar.gz 解压后在zlib根目录下 命令行执行 nmake -f win32/Makefile.msc
3.编译libcurl
a.下载源码 http://curl.haxx.se/download/curl-7.46.0.tar.bz2 b.拷贝所需的openssl与zlib相关库与头文件 .根据curl源代码根目录下winbuild目录下BUILD.WINDOWS.txt的提示 在源代码同级的目录下建立deps文件夹 此时的目录结构如下图伪目录
somedirectory\
|__curl-src
| |_winbuild
|
|__deps|_ lib|_ include|_ bin我这里的deps文件夹目录是 E:\curl\deps 将编译openssl时候安装目录E:\curl\openssl-1.0.2e\develop\include下的 openssl夹拷贝到E:\curl\deps\include\目录下 将zlib源码根目录下的zconf.h、zlib.h和zutil.h拷贝到E:\curl\deps\include目录下。 将E:\curl\openssl-1.0.2e\develop\lib目录下的libeay32.lib和ssleay.lib拷贝到E:\curl\deps\lib目录下 将zlib源码根目录下的zlib.lib拷贝到E:\curl\deps\lib目录下。 c.编译libcurl 命令行进入源代码根目录下 winbuild 目录
nmake RTLIBCFGstatic /f Makefile.vc modestatic VC14 WITH_DEVELE:\curl\deps WITH_SSLstatic ENABLE_SSPIno ENABLE_IPV6no DEBUGno参数详细含义如下
nmake /f Makefile.vc modestatic or dll optionswhere options is one or many of:VC6,7,8,9,10,11,12,14 - VC versionsWITH_DEVELpath - Paths for the development files (SSL, zlib, etc.)Defaults to sibbling directory deps: ../depsLibraries can be fetched at http://windows.php.net/downloads/php-sdk/deps/Uncompress them into the deps folder.WITH_SSLdll or static - Enable OpenSSL support, DLL or staticWITH_CARESdll or static - Enable c-ares support, DLL or staticWITH_ZLIBdll or static - Enable zlib support, DLL or staticWITH_SSH2dll or static - Enable libSSH2 support, DLL or staticENABLE_SSPIyes or no - Enable SSPI support, defaults to yesENABLE_IPV6yes or no - Enable IPv6, defaults to yesENABLE_IDNyes or no - Enable use of Windows IDN APIs, defaults to yesRequires Windows Vista or later, or installation from:http://www.microsoft.com/downloads/details.aspx?FamilyIDAD6158D7-DDBA-416A-9109-07607425A815ENABLE_WINSSLyes or no - Enable native Windows SSL support, defaults to yesGEN_PDByes or no - Generate Program Database (debug symbols for release build)DEBUGyes or no - Debug buildsMACHINEx86 or x64 - Target architecture (default is x86)Static linking of Microsofts C RunTime (CRT):If you are using modestatic nmake will create and link to the static build of
libcurl but *not* the static CRT. If you must you can force nmake to link in
the static CRT by passing RTLIBCFGstatic. Typically you shouldnt use that
option, and nmake will default to the DLL CRT. RTLIBCFG is rarely used and
therefore rarely tested. When passing RTLIBCFG for a configuration that was
already built but not with that option, or if the option was specified
differently, you must destroy the build directory containing the configuration
so that nmake can build it from scratch.Legacy Windows and SSLWhen you build curl using the build files in this directory the default SSL
backend will be WinSSL (Windows SSPI, more specifically Schannel), the native
SSL library that comes with the Windows OS. WinSSL in Windows XP is not able
to connect to servers that no longer support the legacy handshakes and
algorithms used by those versions. If you will be using curl in one of those
earlier versions of Windows you should choose another SSL backend like OpenSSL.3.验证
vs2015 添加好包含目录 附加库目录 附加依赖项后预处理器添加上BUILDING_LIBCURL
