well, I remember adding CMAKE_EXTRA_CACHE_FILE to cmake-utils.eclass for this specific case.
crossdev has config.site support for fixing that kind of failure with autotools, I don't know of any plan to do the same for cmake, not even if it would make sense, so I'll leave crossdev maintainers comment
there isn't much we can do on the ebuild side, what I do with that kind of failure, is:
- fill the TryRunResults.cmake file properly
- copy it to e.g. $SYSROOT/etc/portage/TryRunResults.cmake/${package_name}
- add a "$CAT/$PKG $PKG.conf" line to $SYSROOT/etc/portage/package.env
- create a $SYSROOT/etc/portage/env/$PKG file containing:
CMAKE_EXTRA_CACHE_FILE="${SYSROOT}/etc/portage/TryRunResults.cmake/$PKG"
now portage & cmake-utils.eclass will append this cache file when you build "$CAT/$PKG", giving it the try run result it is asking for
i don't think crossdev is relevant here ... any code using TRY_RUN w/out compile-time fallback is bad. especially when the question can easily be answered w/only compile-time tests. i'm assuming "HAVE_WORDS_BIGENDIAN_EXITCODE" is just a "is the target big endian" test, in which case autotools solved this ages ago. this is sadly people re-inventing autotools (and failing) because they don't understand how to do it properly in the first place. look at the AC_C_BIGENDIAN macro to see how autotools does it using only compile checks. or if you want to fire&forget w/out fixing it upstream, toolchain-funcs has a `tc-endian` func you can insert into the soxr ebuild. |
