curl_version(3) libcurl Manual curl_version(3)NAME
curl_version - returns the libcurl version string
SYNOPSIS
#include <curl/curl.h>
char *curl_version( );
DESCRIPTION
Returns a human readable string with the version number of libcurl and some of its important components (like OpenSSL version).
Note: this returns the actual running lib's version, you might have installed a newer lib's include files in your system which may turn
your LIBCURL_VERSION #define value to differ from this result.
RETURN VALUE
A pointer to a zero terminated string.
SEE ALSO
The LIBCURL_VERSION #define in <curl/curl.h>
BUGS
Surely there are some, you tell me!

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.)
