             Summary: Support cross compiling
                 Key: CLOWNFISH-115
                 URL: https://issues.apache.org/jira/browse/CLOWNFISH-115
             Project: Apache Lucy-Clownfish
          Issue Type: Improvement
            Reporter: Nick Wellnhofer
            Priority: Minor


In order to support cross compiling, we'll have to:

- Rework Charmonizer probes so they don't have to execute any test programs. This is a bit tricky for things like sizeof probes. Some work in this direction has already been done.
- Remove as many things as possible from cfish_platform.h.
-- Endian macros are only used in Lucy's NumberUtils.cfh. This needs to be reworked.
-- The following things are compiler-specific and probably don't have to be adjusted when cross compiling:
--- HAS_*_VARIADIC_MACROS (probably unneeded anyway)
--- HAS_FUNC_MACRO
--- IMPORT, EXPORT, INLINE
--- std headers
-- SIZEOF_* can already be removed. Was only needed for the old Perl labeled params code.
-- U64_TO_DOUBLE can be removed. Was only needed for MSVC6 support.
- If there are any remaining things in cfish_platform.h that can be different on the target platform, add a cross compliation mode to CFC that requires a generated charmony.h.
