Hi,
Over and over again users on HP-UX and Tru64 stumble upon compilation failures
of GNU packages that are due to their use of broken vendor-installed C
compilers.
Examples are these threads:
http://lists.gnu.org/archive/html/bug-gnulib/2008-04/msg00065.html (HP-UX)
http://lists.gnu.org/archive/html/bug-gnulib/2006-08/msg00023.html (OSF/1)
Can we add some recommendations about it in the INSTALL file? I would suggest
a section like this, between the sections "Optional Features" and
"Specifying the System Type".
----------------------------------------------------------------------------
Particular Systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC
is not installed, it is recommended to use the following options in order
to use an ANSI C compiler:
./configure CC="cc -Ae"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler don't grok
its <wchar.h> header file. The option -nodtk can be used as a workaround.
If GNU CC is not installed, it is therefore recommended to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
-----------------------------------------------------------------------------
The INSTALL file in GNU gettext also contains similar advice about AIX 3 and
BeOS, but I think these platforms are not used by many people any more
nowadays.
