25.SH NAME
26curl-config \- Get information about a libcurl installation
27.SH SYNOPSIS
28.B curl-config [options]
29.SH DESCRIPTION
30.B curl-config
31displays information about the curl and libcurl installation.
32.SH OPTIONS
33.IP "--ca"
34Displays the built-in path to the CA cert bundle this libcurl uses.
35.IP "--cc"
36Displays the compiler used to build libcurl.
37.IP "--cflags"
38Set of compiler options (CFLAGS) to use when compiling files that use
39libcurl. Currently that is only the include path to the curl include files.
40.IP "--checkfor [version]"
41Specify the oldest possible libcurl version string you want, and this
42script will return 0 if the current installation is new enough or it
43returns 1 and outputs a text saying that the current version is not new
44enough. (Added in 7.15.4)
45.IP "--configure"
46Displays the arguments given to configure when building curl.
47.IP "--feature"
48Lists what particular main features the installed libcurl was built with. At
49the time of writing, this list may include SSL, KRB4 or IPv6. Do not assume
50any particular order. The keywords will be separated by newlines. There may be
51none, one, or several keywords in the list.
52.IP "--help"
53Displays the available options.
54.IP "--libs"
55Shows the complete set of libs and other linker options you will need in order
56to link your application with libcurl.
57.IP "--prefix"
58This is the prefix used when libcurl was installed. Libcurl is then installed
59in $prefix/lib and its header files are installed in $prefix/include and so
60on. The prefix is set with "configure --prefix".
61.IP "--protocols"
62Lists what particular protocols the installed libcurl was built to support. At
63the time of writing, this list may include HTTP, HTTPS, FTP, FTPS, FILE,
64TELNET, LDAP, DICT. Do not assume any particular order. The protocols will
65be listed using uppercase and are separated by newlines. There may be none,
66one, or several protocols in the list. (Added in 7.13.0)
67.IP "--static-libs"
68Shows the complete set of libs and other linker options you will need in order
69to link your application with libcurl statically. (Added in 7.17.1)
70.IP "--version"
71Outputs version information about the installed libcurl.
72.IP "--vernum"
73Outputs version information about the installed libcurl, in numerical mode.
74This outputs the version number, in hexadecimal, with 8 bits for each part;
75major, minor, patch. So that libcurl 7.7.4 would appear as 070704 and libcurl
7612.13.14 would appear as 0c0d0e... Note that the initial zero might be
77omitted. (This option was broken in the 7.15.0 release.)
78.SH "EXAMPLES"
79What linker options do I need when I link with libcurl?
80
81 $ curl-config --libs
82
83What compiler options do I need when I compile using libcurl functions?
84
85 $ curl-config --cflags
86
87How do I know if libcurl was built with SSL support?
88
89 $ curl-config --feature | grep SSL
90
91What's the installed libcurl version?
92
93 $ curl-config --version
94
95How do I build a single file with a one-line command?
96
