Subject [jira] Commented: (HDFS-1619) Does libhdfs really need to depend on AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T and AC_TYPE_UINT16_T ?

Allen Wittenauer commented on HDFS-1619:
----------------------------------------

The issue that we face is that is nearly impossible to cater to every flavor's customized
autoconf build system (OS X, I'm looking at you).  So we either need to make the autoconf
bits extremely lightweight or pretty much dictate what version gets used.  So however we solve
this particular problem needs to be done in light of the fact that this is a cross-platform
project.

> Currently configure.ac uses AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T and AC_TYPE_UINT16_T
and thus requires autoconf 2.61 or higher. 
> This prevents using it on such platforms as CentOS/RHEL 5.4 and 5.5. Given that those
are pretty popular and also given that it is really difficult to find a platform
> these days that doesn't natively define  intXX_t types I'm curious as to whether we can
simply remove those macros or perhaps fail ONLY if we happen to be on such
> a platform.
