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:

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!

This is just a guess, but I'm suspicious of these lines in
tools/locktest/Makefile.am:
CC=$(CC_FOR_BUILD)
LIBTOOL = @LIBTOOL@ --tag=CC
This might have been an oversite when the original conversion to
automake was done. What happens if you comment those lines out (and
then re-run autogen.sh)? Note that Makefile.am for rpcgen and
rpcdebug also have these lines, but they may not need to be built when
cross-compiling?
K.C.
Hi Kevin,
You're absolutely right. After I removed those lines from
tools/locktest/Makefile.am, tools/rpcdebug/Makefile.am, and
tools/rpcgen/Makefile.am the compile worked successfully.
Thanks for the help!
Here's the patch. I haven't tested it yet, but it allowed me to compile
nfs-utils, so it may at least help others out.
Best,
Patrick Dignan
