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.
              Currently 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
              returns  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 order. The keywords are 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 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 "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 and many more. Do not assume any particular order. The  protocols  are  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 appear comma-separated.  (Added
              in 7.58.0)

       --static-libs
              Shows the complete set of libs and other linker options you 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
              shows the version number, in hexadecimal, using 8 bits for each part: major, minor,
              and  patch  numbers. This makes libcurl 7.7.4 appear as 070704 and libcurl 12.13.14
              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 source.c `curl-config --libs`
