1 Building with Visual C++, prerequises 2 ===================================== 3 4 This document describes how to compile, build and install curl and libcurl 5 from sources using the Visual C++ build tool. To build with VC++, you will 6 of course have to first install VC++. The minimum required version of 7 VC is 6 (part of Visual Studio 6). However using a more recent version is 8 strongly recommended. 9 10 VC++ is also part of the Windows Platform SDK. You do not have to install 11 the full Visual Studio or Visual C++ if all you want is to build curl. 12 13 The latest Platform SDK can be downloaded freely from: 14 15 http://msdn.microsoft.com/en-us/windows/bb980924 16 17 If you are building with VC6 then you will also need the February 2003 18 Edition of the Platform SDK which can be downloaded from: 19 20 http://www.microsoft.com/en-us/download/details.aspx?id=12261 21 22 If you wish to support zlib, openssl, c-ares, ssh2, you will have to download 23 them separately and copy them to the deps directory as shown below: 24 25 somedirectory\ 26 |_curl-src 27 | |_winbuild 28 | 29 |_deps 30 |_ lib 31 |_ include 32 |_ bin 33 34 It is also possible to create the deps directory in some other random 35 places and tell the Makefile its location using the WITH_DEVEL option. 36 37 Building with Visual C++ 38 ======================== 39 40 Open a Visual Studio Command prompt or the SDK CMD shell. 41 42 Using the CMD Shell: 43 choose the right environment via the setenv command (see setenv /?) 44 for the full list of options. setenv /xp /x86 /release for example. 45 46 Using the Visual Studio command prompt Shell: 47 Everything is already pre-configured by calling one of the command 48 prompt. 49 50 Once you are in the console, go to the winbuild directory in the Curl 51 sources: 52 cd curl-src\winbuild 53 54 Then you can call nmake /f Makefile.vc with the desired options (see below). 55 The builds will be in the top src directory, builds\ directory, in 56 a directory named using the options given to the nmake call. 57 58 nmake /f Makefile.vc mode=<static or dll> <options> 59 60 where <options> is one or many of: 61 VC=<6,7,8,9,10,11,12> - VC versions 62 WITH_DEVEL=<path> - Paths for the development files (SSL, zlib, etc.) 63 Defaults to sibbling directory deps: ../deps 64 Libraries can be fetched at http://windows.php.net/downloads/php-sdk/deps/ 65 Uncompress them into the deps folder. 66 WITH_SSL=<dll or static> - Enable OpenSSL support, DLL or static 67 WITH_CARES=<dll or static> - Enable c-ares support, DLL or static 68 WITH_ZLIB=<dll or static> - Enable zlib support, DLL or static 69 WITH_SSH2=<dll or static> - Enable libSSH2 support, DLL or static 70 ENABLE_SSPI=<yes or no> - Enable SSPI support, defaults to yes 71 ENABLE_IPV6=<yes or no> - Enable IPv6, defaults to yes 72 ENABLE_IDN=<yes or no> - Enable use of Windows IDN APIs, defaults to yes 73 Requires Windows Vista or later, or installation from: 74 http://www.microsoft.com/downloads/details.aspx?FamilyID=AD6158D7-DDBA-416A-9109-07607425A815 75 ENABLE_WINSSL=<yes or no> - Enable native Windows SSL support, defaults to yes 76 GEN_PDB=<yes or no> - Generate Program Database (debug symbols for release build) 77 DEBUG=<yes or no> - Debug builds 78 MACHINE=<x86 or x64> - Target architecture (default is x86) 79 80 Static linking of Microsoft's C RunTime (CRT): 81 ============================================== 82 If you are using mode=static nmake will create and link to the static build of 83 libcurl but *not* the static CRT. If you must you can force nmake to link in 84 the static CRT by passing RTLIBCFG=static. Typically you shouldn't use that 85 option, and nmake will default to the DLL CRT. RTLIBCFG is rarely used and 86 therefore rarely tested. When passing RTLIBCFG for a configuration that was 87 already built but not with that option, or if the option was specified 88 differently, you must destroy the build directory containing the configuration 89 so that nmake can build it from scratch. 90
