.SH SYNOPSIS
|
|
\fBcurl\-config [options]\fP
|
|
.SH DESCRIPTION
|
|
\fBcurl\-config\fP
|
|
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
|
|
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)
|
|
.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 are 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 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 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)
|
|
.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 appear comma\-separated.
|
|
(Added in 7.58.0)
|
|
.IP --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)
|
|
.IP --version
|
|
Outputs version information about the installed libcurl.
|
|
.IP --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.)
