curl-config(1) General Commands Manual curl-config(1)
curl-config - Get information about a libcurl installation
curl-config [options]
curl-config displays information about the curl and libcurl
installation.
--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.)
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`
