Avoid the horror of an unintelligible build breakage! LD_LIBRARY_PATH=../lib:../stubdata:../tools/ctestfw:$LD_LIBRARY_PATH ../bin/icupkg -tb ./in/icudt49l.dat ./out/icudt49b.dat udata_swapDataHeader(): header size mismatch - headerSize 32768 infoSize 5120 length 1024 make[1]: *** [out/icudt49b.dat] Error 8 make[1]: Leaving directory `/builddir/build/BUILD/icu/source/data' make: *** [all-recursive] Error 2 This requires the simple setting of a CPPFLAG which is trivial, as outlined below. Top of spec file: %{!?endian: %global endian %(%{__python} -c "import sys;print (0 if sys.byteorder=='big' else 1)")} Before the %configure # Endian: BE=0 LE=1 %if ! 0%{?endian} CPPFLAGS="-DU_IS_BIG_ENDIAN=1" %endif You would think that rpm would have had an endianess macro/test variable by now. Oh well. Phil =--=
export CPPFLAGS="-DU_IS_BIG_ENDIAN=1" ^^^^^^ and BuildRequires: doxygen, autoconf, python ^^^^^^ Sorry I was a bit careless Phil =--=
All variables in the %build section are not exported, so it shouldn't be necessary for this one? Anyhow, just pushed a change without export.
