|
|
.SH SYNOPSIS
|
|
.B curl-config [options]
|
|
.SH DESCRIPTION
|
|
.B curl-config
|
|
displays information about the curl and libcurl installation.
|
|
.SH OPTIONS
|
|
.IP "--ca"
|
|
Displays the built-in path to the CA cert bundle this libcurl uses.
|
|
.IP "--cc"
|
|
Displays the compiler used to build libcurl.
|
|
.IP "--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.
|
|
.IP "--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)
|
|
.IP "--configure"
|
|
Displays the arguments given to configure when building curl.
|
|
.IP "--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.
|
|
.IP "--help"
|
|
Displays the available options.
|
|
.IP "--libs"
|
|
Shows the complete set of libs and other linker options you will need in order
|
|
to link your application with libcurl.
|
|
.IP "--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".
|
|
.IP "--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)
|
|
.IP "--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 will appear
|
|
comma-separated. (Added in 7.58.0)
|
|
.IP "--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)
|
|
.IP "--version"
|
|
Outputs version information about the installed libcurl.
|
|
.IP "--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.)
