I was trying to build GNU grep on a NetBSD 9.3 machine when I saw this
nasty bit of business :
I just now built grep 3.11 on NetBSD 9.3 x86-64, and didn't run into any
problems.
On x86_64 it is not a problem at all. Usually.
/usr/pkg/gcc10/bin/gcc
The default GCC on NetBSD 9.3 x86-64 is GCC 7.5.0. I installed gcc10
(the instructions for this are not obvious for a non-NetBSD user, by the
way), and still could not reproduce the problem.
I assure you, nothing seems obvious in the NetBSD world. At least not
for me. However it is a pretty darn stable platform and so long as you
have a compiler and a libC with a few other things then building from
source *may* work for most things. Maybe. No promises. I just like
the fact that it seems to run on just about anything and that includes
a toaster if there is a CPU and some memory. :)
I see that you are running NetBSD on the sparc
Not for long. That old thing is heading for the re-cycle scrap heap.
extensive set of unusual compile-time options like "-std=iso9899:1999",
Not sure when C99 became "unusual" but I hear that sort of feedback all
the time from various projects. Which is to say there is no real C lang
specification at all in a lot of places. Just whatever GCC or LLVM/Clang
can compile and good luck with that. Even the OpenSSL project is all
over the map with whatever C spec they pretend to conform to. Thankfully
Curl/libCurl is still run by one top level person and it compiles on
just about everything with C90 still. However ... I digress.
All the rest of those switches are to disable features. I have seen a
SIGILL in some places just because of that VIS stuff. I still do not
know what is going on there.
whereas my simpler approach causes 'configure' to use '-std=gnu11' which
may explain why I don't run into problems. What happens if you just do a
plain "configure; make" with the ordinary GCC? If that works, then you
might try seeing which option or options cause the problem.
Worth a try I guess. However this is end of September. Actually day 1 of
October and I was trying to toss out these last sparc machines from my
life. I just wanted to give them a whirl one last time. They do make
excellent room heaters and power users.
Also, if you're not already doing so, please build grep 3.11 as opposed
to any older grep version.
Well, yes, this is from the 3.11 tarball.
In any case I will let it rip with a trivial configure and perhaps the
default compiler and see what happens. Let us not waste further time or
electricity on it.
