NAME
curl-config - Get information about a libcurl installation

SYNOPSIS
curl-config [options]

DESCRIPTION
curl-config displays information about a previous curl and libcurl installation.

OPTIONS
--ca Displays the built-in path to the CA cert bundle this libcurl uses.

--cc Displays the compiler used to build libcurl.

--cflags
Set of compiler options (CFLAGS) to use when compiling files that use
libcurl. Currently that is only thw include path to the curl include files.

--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)

--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.

--help Displays the available options.

--libs Shows the complete set of libs and other linker options you will need in
order to link your application with libcurl.

--prefix
This is the prefix used when libcurl was installed. Libcurl is then
installed in $prefix/lib and its header files are installed in $pre-
fix/include and so on. The prefix is set with "configure --prefix".

--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)

--version
Outputs version information about the installed libcurl.

--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.)

EXAMPLES
What linker options do I need when I link with libcurl?

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?
