Hi again.

using 1.6.0 I get some odd messages about "-march= switch"

It's only a warning but if there is a conflict it needs to be resolved:
which value is taking precendence in this "conflict"?

I did not set switch so I'm not clear where this came from . why is
there a problem specifying a the cpu when using ct-ng?

thanks.

OK, I found a thread on nabble where a similar problem was fixed by ct-ng distclean.

I'll assume that fixes it and start again.

regards.


Oh well. I spoke too soon.


Even with a disclean and new tarballs I'm still getting both the nptl and a ton of -march conficts in gcc.

however from the build.log:


[DEBUG]    CT_LIBC_SUPPORT_NPTL=y
[DEBUG]    CT_LIBC_SUPPORT_LINUXTHREADS=y
[DEBUG]    CT_THREADS="nptl"
[DEBUG]    CT_THREADS_NPTL=y
[DEBUG]    # CT_THREADS_LINUXTHREADS is not set
[DEBUG]    # CT_THREADS_NONE is not set



[DEBUG]    CT_ARCH_ARCH="armv4t"
[DEBUG]    CT_ARCH_CPU="ep9312

So why is ct-ng apparently not passing my NPTL and ARCH to configure ?

thanks.
