Re: [libgfortran,patch] Add compiler check when configuring libgfortran


checking whether the GNU Fortran compiler is working... no
configure: error: GNU Fortran is not working; please report a bug in
http://gcc.gnu.org/bugzilla, attaching
/home/fxcoudert/svn/debug3/ibin/i686-pc-linux-gnu/libgfortran/ config.log

Perhaps we can tell the user to first look into the failure? The error
message could mention a few hints about GMP and MFPR too.

On 4.2, yes. On 4.3, GMP or MPFR mislinking would now show up earlier than that, so there's no need for a specific error message.


Bootstrapped and tested on i686-linux. OK for mainline? Would it be OK
to backport this to 4.2, a few weeks after it has been commited to
mainline? (I think it's an annoying bug for users compiling on unusual
platforms or using unusual configurations).

unusual == non-Linux I presume? Solaris is definitely not unusual. I'd second putting this on the 4.2 branch, rather sooner than later.

That would be "unusual configuration", that is, neither system libs nor in-tree (as will soon be possible). Otherwise, no, Solaris is not unusual (although it's not used much for scientific calculation anymore, in my field anyway).
