| 25 | .SH NAME |
| 26 | curl-config \- Get information about a libcurl installation |
| 27 | .SH SYNOPSIS |
| 28 | .B curl-config [options] |
| 29 | .SH DESCRIPTION |
| 30 | .B curl-config |
| 31 | displays information about the curl and libcurl installation. |
| 32 | .SH OPTIONS |
| 33 | .IP "--ca" |
| 34 | Displays the built-in path to the CA cert bundle this libcurl uses. |
| 35 | .IP "--cc" |
| 36 | Displays the compiler used to build libcurl. |
| 37 | .IP "--cflags" |
| 38 | Set of compiler options (CFLAGS) to use when compiling files that use |
| 39 | libcurl. Currently that is only the include path to the curl include files. |
| 40 | .IP "--checkfor [version]" |
| 41 | Specify the oldest possible libcurl version string you want, and this |
| 42 | script will return 0 if the current installation is new enough or it |
| 43 | returns 1 and outputs a text saying that the current version is not new |
| 44 | enough. (Added in 7.15.4) |
| 45 | .IP "--configure" |
| 46 | Displays the arguments given to configure when building curl. |
| 47 | .IP "--feature" |
| 48 | Lists what particular main features the installed libcurl was built with. At |
| 49 | the time of writing, this list may include SSL, KRB4 or IPv6. Do not assume |
| 50 | any particular order. The keywords will be separated by newlines. There may be |
| 51 | none, one, or several keywords in the list. |
| 52 | .IP "--help" |
| 53 | Displays the available options. |
| 54 | .IP "--libs" |
| 55 | Shows the complete set of libs and other linker options you will need in order |
| 56 | to link your application with libcurl. |
| 57 | .IP "--prefix" |
| 58 | This is the prefix used when libcurl was installed. Libcurl is then installed |
| 59 | in $prefix/lib and its header files are installed in $prefix/include and so |
| 60 | on. The prefix is set with "configure --prefix". |
| 61 | .IP "--protocols" |
| 62 | Lists what particular protocols the installed libcurl was built to support. At |
| 63 | the time of writing, this list may include HTTP, HTTPS, FTP, FTPS, FILE, |
| 64 | TELNET, LDAP, DICT. Do not assume any particular order. The protocols will |
| 65 | be listed using uppercase and are separated by newlines. There may be none, |
| 66 | one, or several protocols in the list. (Added in 7.13.0) |
| 67 | .IP "--static-libs" |
| 68 | Shows the complete set of libs and other linker options you will need in order |
| 69 | to link your application with libcurl statically. (Added in 7.17.1) |
| 70 | .IP "--version" |
| 71 | Outputs version information about the installed libcurl. |
| 72 | .IP "--vernum" |
| 73 | Outputs version information about the installed libcurl, in numerical mode. |
| 74 | This outputs the version number, in hexadecimal, with 8 bits for each part; |
| 75 | major, minor, patch. So that libcurl 7.7.4 would appear as 070704 and libcurl |
| 76 | 12.13.14 would appear as 0c0d0e... Note that the initial zero might be |
| 77 | omitted. (This option was broken in the 7.15.0 release.) |
| 78 | .SH "EXAMPLES" |
| 79 | What linker options do I need when I link with libcurl? |
| 80 | |
| 81 | $ curl-config --libs |
| 82 | |
| 83 | What compiler options do I need when I compile using libcurl functions? |
| 84 | |
| 85 | $ curl-config --cflags |
| 86 | |
| 87 | How do I know if libcurl was built with SSL support? |
| 88 | |
| 89 | $ curl-config --feature | grep SSL |
| 90 | |
| 91 | What's the installed libcurl version? |
| 92 | |
| 93 | $ curl-config --version |
| 94 | |
| 95 | How do I build a single file with a one-line command? |
| 96 | |
| 97 | $ `curl-config --cc --cflags` -o example example.c `curl-config --libs` |
