curl-config

NAME

SYNOPSIS

DESCRIPTION

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)

--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.)
