I was working on that, and it caused a conflict. Comparing the two versions, I reverted it and used mine instead. The differences are: 1. The current version uses AC_TRY_COMPILE; the previous version used AC_TRY_RUN, which is unnecessary effort and won't work when cross-compiling. 2. The current version uses HAVE_LONG_LONG_INT rather than HAVE_LONG_LONG, as that is the name used by the AC_TYPE_LONG_LONG_INT macro in more recent versions of autoconf. > It defines HAVE_LONG_LONG macro (in include/config.h) so offending code > can be segregated. > > Affected code: > - r.info > - r.terraflow > - g.region > - lib/vector/dglib/type.h I have fixed g.region. I also fixed the r.info fix: 1. The format specifier for unsigned int is %u; %d is signed. 2. "long long" values need %llu/%lld rather than %lu/%ld. AFAICT, dglib and r.terraflow remain untouched. dglib is awkward because the 64-bit values are part of the file format, so you can't just use a 32-bit int if long long isn't available. I'm not sure what the situation is with C++, i.e. whether "long long" is part of the standard. If it isn't, we need another check; whether the C compiler supports "long long" and whether the C++ compiler supports it are separate issues. -- Glynn Clements <[EMAIL PROTECTED]> _______________________________________________ grass-dev mailing list grass-dev@grass.itc.it http://grass.itc.it/mailman/listinfo/grass-dev
