Hi,
I'm attempting to cross-compile nfs-utils 1.1.4 for ARM on an x86_64 build machine. I can cross-compile other software, but nfs-utils fails. I get the following error:

cc1: error: unrecognized command line option "-mfpu=vfpv3-d16"

testlk.c:1: error: bad value (armv7-a) for -march= switch
testlk.c:1: error: bad value (cortex-a8) for -mtune= switch
I'm guessing there's some sort of problem in Makefile.am that's causing it to fail, but I am not sure what changes I need to make. Does anyone know the solution to this problem or where I might start looking to fix this?
My guess would be your cross-compiler is added those to the CFLAGS because
those flags are not set on a "normal" compilation...
steved.

I believe you are correct, however I think it should be using the ARM
specific compiler when trying to cross-compile. I don't know enough
about automake and cross-compiling to be sure, but I think that it
doesn't set the CC variable correctly. It does seem to configure
correctly though, since it shows the proper compiler being found:
"checking for armv7a-cros-linux-gnueabi-gcc... (cached)
armv7a-cros-linux-gnueabi-gcc", but then it uses the normal gcc.
Thanks for the help!
Best,
Patrick Dignan
