dnl This package is called cyginfra, partly for historical reasons

dnl and partly to avoid reorganizing the testsuite subdirectory.

dnl The generated header file may get #include'd indirectly by other

dnl packages, so it is not a good idea to define package and version.

dnl

dnl The purpose of this infrastructure implementation is to provide a way

dnl of giving host code access to the same set of assertions and tracing

dnl facilities as are available on the target side. The implementations

dnl of these facilities has to be rather different, for example the host

dnl side has to worry about running in both command-line and GUI tools,

dnl not to mention supporting different languages such as Tcl as well

dnl as C and C++.

dnl

dnl After a successful build there should be a library libcyginfra.a

dnl which can be linked with the application code and which can get

dnl installed. In addition there will be a set of header files.

dnl

dnl The infrastructure exports four main header files:

dnl

dnl    cyg/infra/cyg_type.h     data types, useful macros, and a

dnl                             few compiler-related odds and ends

dnl

dnl    cyg/infra/cyg_ass.h      lots of lovely assertion macros

dnl

dnl    cyg/infra/cyg_trac.h     lots of lovely trace macros

dnl

dnl    cyg/infra/testcase.h     routines for use in testcases

dnl

dnl These header files are shared between host and target side, to make

dnl sure that a consistent set of macros is used between the two. There

dnl are a number of host-specific extensions in the header files as

dnl well.

dnl

dnl The header files rely on a number of other header files:

dnl

dnl    pkgconf/infra.h

dnl    cyg/hal/basetype.h

dnl

dnl Obviously cyg/hal/basetype.h cannot be shared between host and target,

dnl instead it has to depend on autoconf information.

dnl

dnl Sharing pkgconf/infra.h between host and target is slightly more feasible,

dnl especially if we get the configuration tool to a point where it can

dnl be used for both host and target. However for now this would create a

dnl bit of confusion because two configuration systems would be in use, and

dnl it seems better to stick with just autoconf for now. Therefore

dnl pkgconf/infra.h #include's the file generated by autoconf and

dnl generates the appropriate #define's (it is not a good idea to have

dnl autoconf generate pkgconf/infra.h directly, autoconf is slightly too

dnl eager to do substitutions).

dnl

dnl The configuration header file that is normally generated is

dnl config.h. It is more in keeping with eCos conventions to have

dnl a different header file hostinfra.h instead. This can

dnl achieved using the appropriate AM_CONFIG_HEADER macro.

dnl

dnl Making the copies of cyg_type.h etc. is the responsibility of

dnl Makefile.am, configure is responsible only for the makefile and for

dnl hostinfra.h.
