NAME
       curl-config - Get information about a libcurl installation

SYNOPSIS
       curl-config [options]

DESCRIPTION
       curl-config displays information about the 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. Cur‐
              rently that is only the include path to the curl include files.

       --checkfor [version]
              Specify the oldest possible libcurl version string you want, and this script will  re‐
              turn  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)

       --configure
              Displays the arguments given to configure when building curl.

       --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 or‐
              der. 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 $pre‐
              fix/lib and its header files are installed in $prefix/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)

       --ssl-backends
              Lists the SSL backends that were enabled when libcurl was built. It might be  no,  one
              or  several  names. If more than one name, they will appear comma-separated. (Added in
              7.58.0)

       --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)

       --version
              Outputs version information about the installed libcurl.

       --vernum
              Outputs version information about the installed libcurl, in numerical mode.  This out‐
              puts the version number, in hexadecimal, with 8 bits for each part: major, minor,  and
              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` -o example example.c `curl-config --libs`
