我正在试图build立与zlib，ssh2和openssl支持curl dll库
但是，当我指定release-dll-ssl-dll-ssh2-dll-zlib-dll
我得到这个清单：
Usage: nmake /f makefile.vc9 CFG=<config> <target> where <config> is one of: release - release static library release-ssl - release static library with ssl release-zlib - release static library with zlib release-ssl-zlib - release static library with ssl and zlib release-ssl-ssh2-zlib - release static library with ssl, ssh2 and zlib release-ssl-dll - release static library with dynamic ssl release-zlib-dll - release static library with dynamic zlib release-ssl-dll-zlib-dll - release static library with dynamic ssl and dynamic zlib release-dll - release dynamic library release-dll-ssl-dll - release dynamic library with dynamic ssl release-dll-zlib-dll - release dynamic library with dynamic zlib release-dll-ssl-dll-zlib-dll - release dynamic library with dynamic ssl and dynamic zlib debug - debug static library debug-ssl - debug static library with ssl debug-zlib - debug static library with zlib debug-ssl-zlib - debug static library with ssl and zlib debug-ssl-ssh2-zlib - debug static library with ssl, ssh2 and zlib debug-ssl-dll - debug static library with dynamic ssl debug-zlib-dll - debug static library with dynamic zlib debug-ssl-dll-zlib-dll - debug static library with dynamic ssl and dynamic zlib debug-dll - debug dynamic library debug-dll-ssl-dll - debug dynamic library with dynamic ssl debug-dll-zlib-dll - debug dynamic library with dynamic zlib1 debug-dll-ssl-dll-zlib-dll - debug dynamic library with dynamic ssl and dynamic zlib <target> can be left blank in which case all is assumed Makefile.vc9(476) : fatal error U1050: please choose a valid configuration "release-dll-ssl-dll-zlib-dll-ssh2-dll"
用release-ssl-dll-zlib-dll构build工作正常，但是我也需要sftp。
为什么这个选项不存在？
有没有解决的办法？
答案是：你不能
CFG=release-ssl-ssh2-zlib建立curl。 在构建之后，如果你想要构建一些东西（比如说PHP），你需要将libssh2.lib添加到lincurl.lib中。 这可以用这个命令来完成（设置路径到你的libssh2.lib和libcurl.lib）：
lib.exe /OUT:libcurl_merged.lib libssh2.lib libcurl.lib copy libcurl_merged.lib libcurl.lib
您可以使用非标准的构建脚本“Makefile.vc”窗体“winbuild”文件夹。
x64动态库示例：
cd curl-src\winbuild nmake /f Makefile.vc mode=dll VC=14 MACHINE=x64 DEBUG=no GEN_PDB=yes WITH_SSL=dll WITH_ZLIB=dll WITH_SSH2=dll
构建将位于顶部curl-src目录中，并在使用给nmake调用的选项命名的目录中建立\目录。
