curl-config - Get information about a libcurl installation
</PRE>
<H2>SYNOPSIS</H2><PRE>
<B>curl-config</B> <B>[options]</B>
</PRE>
<H2>DESCRIPTION</H2><PRE>
<B>curl-config</B> displays information about a previous curl and
libcurl installation.
</PRE>
<H2>OPTIONS</H2><PRE>
--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 com-
piling 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 appli-
cation 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 ver-
sion 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...
What linker options do I need when I link with libcurl?
$ curl-config --libs
What compiler options do I need when I compile using
libcurl functions?
$ curl-config --cflags
How do I know if libcurl was built with SSL support?
$ curl-config --feature | grep SSL
What's the installed libcurl version?
$ curl-config --version
How do I build a single file with a one-line command?
$ `curl-config --cc --cflags --libs` -o example exam-
ple.c
