DESCRIPTIONcurl-config displays information about a previous curl and libcurl
OPTIONS--ca Displays the built-in path to the CA cert bundle this libcurl
--cc Displays the compiler used to build libcurl.
Set of compiler options (CFLAGS) to use when compiling files
that use libcurl. Currently that is only thw include path to the
curl include files.
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 cur‐
rent version is not new enough. (Added in 7.15.4)
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.
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
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)
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)
Outputs version information about the installed libcurl.
Outputs version information about the installed libcurl, in
numerical mode. This outputs the version number, in hexadeci‐
mal, 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.)
What linker options do I need when I link with libcurl?
What compiler options do I need when I compile using libcurl functions?
How do I know if libcurl was built with SSL support?
$ curl-config--feature | grep SSL
What's the installed libcurl version?
How do I build a single file with a one-line command?
$ `curl-config --cc --cflags --libs` -o example example.c
