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 cur-rent current
              rent 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 writ-ing, writing,
              ing, 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 $prefix/include and so on. The prefix is set with  "con-figure "configure
              figure --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 new-lines. newlines.
              lines. 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?

         $ 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
