[GRASS5] Re: bug in configure routine

[Andreas Lange]

Hi Eric,

i am not an autoconf expert, but i gained some expirience in
hand-crafting the header files for IRIX and the cygwin setup.

Should i send you the header.* files so that you can see which
setups/paths work?

cu,

Andreas

I watched this too on IRIX. But i think that if there is a library of
that name (libsun? libnsl??, can't remember) the inclusion would not
hurt.
There are many messages in the form "libxyz not used to resolve any
symbol...". 
Does that mean that the library is linked into the binary even if it is
not used to resolve anything? That would bloat the executable.

On IRIX there seems to be a difference if you use MIPS PRO native SGI
compiler or gcc. Using gcc i have always the problem that the libraries
are found in lib, but in lib the library is in the old format, whilst
gcc compiles in the new (n32 ABI) format. So the library search path
must be lib32 (/usr/lib32, /usr/local/lib32, /usr/freeware/lib32). If
you have a 64bit machine and compile in the new 64bit mode, you'll find
the libraries in lib64, but i expect this not to work without heavy code
modification.
