[Debian-med-packaging] Endianness of libsis-base [Was: failed powerpc build of libsis-base-java 14.12.0-2]

[Bernd Rinn]

Hi Andreas,

There is no automatic detection of the endiness of a platform in
libsis-base, but this is a compile time setting for the C library. I
assume that you will find somewhere in your build scripts for PowerPC

   -DMACHINE_BYTE_ORDER=1

which means: platform is 'little endian', when you actually should have
there

   -DMACHINE_BYTE_ORDER=2

which stands for 'platform is big endian'. The particular test that you
found is failing checks whether the platform really has the endiness
that was specified in the build file.

All the best,

Bernd
