curl-config [options]

## DESCRIPTION

curl-config displays information about a previous curl and libcurl installation.

## 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 thw include path to the curl include files.

--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".

--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...

## EXAMPLES
