wrobell <wrobell at pld-linux.org> added the comment:
looking into configure.in the above fails due to following check
AC_MSG_CHECKING(for %lld and %llu printf() format support)
the check compiles and tries to _run_ a bit of software to determine lld/llu support.
that of course fails (we are cross compiling). this is similar problem to ptmx/ptc problem (we do not know if host have support for ptmx/ptc).
i wonder if the following would be acceptable
1. if in cross compilation mode, the configure.in could load config-cross.site.
2. the config-cross.site would define variables for ptmx/ptc, long long format and other checks which consist of running code snippets
3. appropriate checks (i.e. ptmx/ptc, lld/llu) would not be run in cross compilation mode. variables from config-cross.site would be used instead.
4. it would be a developer responsibility to set appropriate values for his platform in config-cross.site file.
does above sound like a solution?
