// The purpose of this header file is to replicate appropriate
|
|
// functionality from the target-side header file <pkgconf/infra.h>.
|
|
// This header file is intended to contain configuration options
|
|
// related to the implementation of the infrastructure, as opposed
|
|
// to how that infrastructure gets used by other packages. A good
|
|
// example would be a configuration option to control the size
|
|
// of the circular trace buffer.
|
|
//
|
|
// On the host side these things are handled by autoconf, and in
|
|
// particular the configure.in script will offer command-line
|
|
// arguments allowing the relevant options to be controlled.
|
|
// The relevant information will end up in <cyg/pkgconf/hostinfra.h>
|
|
# include <pkgconf/hostinfra.h>
|
|
|
|
// Some options should always be enabled in this header file.

|
|
|
// Other options should be decided on a package by package basis,
|
|
// e.g. whether or not assertions are used. On the host side it is
|
|
// not appropriate to control these globally, instead the infrastructure
|
|
// always provides the necessary functionality and it is up to the
|
|
// other parts of the system to decide whether or not the facilities
|
|
// get used.
|
|
|
|
// A third set of options deal with the environment, e.g. the sizes
|
|
// of various data types. autoconf macros take care of most of the
|
|
// work, but some translation is needed into eCos-style names to
|
|
// avoid namespace pollution.
