| .TH curl-config 1 "25 Oct 2007" "Curl 7.17.1" "curl-config manual" |
| .SH NAME |
| curl-config \- Get information about a libcurl installation |
| .SH SYNOPSIS |
| .B curl-config [options] |
| .SH DESCRIPTION |
| .B curl-config |
| displays information about the curl and libcurl installation. |
| .SH OPTIONS |
| .IP "--ca" |
| Displays the built-in path to the CA cert bundle this libcurl uses. |
| .IP "--cc" |
| Displays the compiler used to build libcurl. |
| .IP "--cflags" |
| Set of compiler options (CFLAGS) to use when compiling files that use |
| libcurl. Currently that is only the include path to the curl include files. |
| .IP "--checkfor [version]" |
| Specify the oldest possible libcurl version string you want, and this |
| script will return 0 if the current installation is new enough or it |
| returns 1 and outputs a text saying that the current version is not new |
| enough. (Added in 7.15.4) |
| .IP "--configure" |
| Displays the arguments given to configure when building curl. |
| .IP "--feature" |
| Lists what particular main features the installed libcurl was built with. At |
| the time of writing, this list may include SSL, KRB4 or IPv6. Do not assume |
| any particular order. The keywords will be separated by newlines. There may be |
| none, one, or several keywords in the list. |
| .IP "--help" |
| Displays the available options. |
| .IP "--libs" |
| Shows the complete set of libs and other linker options you will need in order |
| to link your application with libcurl. |
| .IP "--prefix" |
| This is the prefix used when libcurl was installed. Libcurl is then installed |
| in $prefix/lib and its header files are installed in $prefix/include and so |
| on. The prefix is set with "configure --prefix". |
| .IP "--protocols" |
| Lists what particular protocols the installed libcurl was built to support. At |
| the time of writing, this list may include HTTP, HTTPS, FTP, FTPS, FILE, |
| TELNET, LDAP, DICT. Do not assume any particular order. The protocols will |
| be listed using uppercase and are separated by newlines. There may be none, |
| one, or several protocols in the list. (Added in 7.13.0) |
| .IP "--static-libs" |
| Shows the complete set of libs and other linker options you will need in order |
| to link your application with libcurl statically. (Added in 7.17.1) |
| .IP "--version" |
| Outputs version information about the installed libcurl. |
| .IP "--vernum" |
| Outputs version information about the installed libcurl, in numerical mode. |
| This outputs the version number, in hexadecimal, with 8 bits for each part; |
| major, minor, patch. So that libcurl 7.7.4 would appear as 070704 and libcurl |
| 12.13.14 would appear as 0c0d0e... Note that the initial zero might be |
| omitted. (This option was broken in the 7.15.0 release.) |
| .SH "EXAMPLES" |
| What linker options do I need when I link with libcurl? |
| |
| $ curl-config --libs |
| |
| What compiler options do I need when I compile using libcurl functions? |
| |
| $ curl-config --cflags |
| |
| How do I know if libcurl was built with SSL support? |
| |
| $ curl-config --feature | grep SSL |
| |
| What's the installed libcurl version? |
| |
| $ curl-config --version |
| |
| How do I build a single file with a one-line command? |
| |
| $ `curl-config --cc --cflags --libs` -o example example.c |
| |
| .SH "SEE ALSO" |
| .BR curl (1) |
