Could compile full uClinux-dist but with a recent kernel 4.5 (> 3.5).

am i doing something wrong ?
If you compile the c++ app within the uclinux-dist do you get the same
result?
Can you post the c++ app?
Or at least a simple test case that shows the problem?

It is required because it fails to compile without it :-)
I don't know why it fails, I didn't dig any further into it.

exactly Larry's solution from that thread.

I don't know. It was in that script before I started using it.
It hasn't caused any problems with it there so I have never
removed it.
Both works fine for me and the second workaround
is simpler than my old way via a extra gcc spec file
and a gcc-wrapper script.
So when you are compiling a modern gcc for m68k-uclinux you
don't hit the problem compiling linux-atomic.c?

I think it is still required. Without it, an image for
qemu-system-m68k does not boot completely.

I hit it. And I would like to get it resolved upstream.
Furthermore the buildroot people are very strict about submissions
and want to know all glory details about a required patch :)
So I just thought I might get some more detailed explanation from
the uClinux experts.

Re: [uClinux-dev] toolchain for c++ on coldfire
Hi all, Greg, i finally have the toolchain created, had to go over the 2 follwing issues: 1) as you pointed out, uclibc headers install path was not correct, had to modify manually uClibc.X.X/.config with the correct RUNTIME_PREFIX= DEVEL_PREFIX= under include, i have now all libc includes. 2) compilation was still breaking on checking whether to use setjmp/longjmp exceptions... unknown configure: error: unable to detect exception model I replaced binutils 2.26 with 2.25, all worked fine. Btw, using the new generated toolchain to compile a c++ app, i still get same error i had with older uclinux toolchians: src/manager.cc:88:15: error: ‘usleep’ was not declared in this scope usleep(1); ^ makefile:37: set di istruzioni per l'obiettivo "obj/manager.o" non riuscito make: *** [obj/irc_manager.o] Errore 1 Thomas, many thanks, will try buildroot in case.

That is where I would expect these configure checks. Any way, most of those headers should be found (so "... yes"). It looks like the header install step didn't work as expected.
