Hi, On AIX 5.1 and AIX 5.2, building coreutils-8.11 is not possible out of the box, because dd.c has an enum that tries to set a new constant O_NOCACHE. On these machines, O_NOCACHE is a preprocessor define in /usr/include/fcntl.c, so the symbol in the dd.c enum definition is replaced by a constant before the compiler sees it, so can't be compiled as is. I worked around it as follows: gsed -i -e 's|O_NOCACHE|DD_NOCACHE|g' src/dd.c I am not subscribed to this list, so please keep me in Cc for any followups. Cheers, -- Gary V.
