curl-config(1)

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 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)

   --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
          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 "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)

   --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   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`  -o  example  example.c  `curl-config
   --libs`
