  This comment was not very clear to me.  I guess you mean

  When you use GENTARGETS, you must also specify the install commands.
However, you can probably keep using AUTOTARGETS.  Even when you use
AUTOTARGETS, it is possible to override the CONFIGURE_CMDS and BUILD_CMDS.
But you don't even need to override the BUILD_CMDS.  Instead, you can
pass additional options to the MAKE call, by defining

V86D_MAKE_OPT += CC="$(TARGET_CC) -D__i386__"

  (As Thomas mentioned, if you assign twice on the command line it is only
the last one that counts.)

  I can't guarantee that what I'm saying is correct, though, so be sure to
test with a clean build before resending.

  Regards,
  Arnout

Thanks for your feedback. Indeed, the configure script calls uname -m
by default, that is, assumes host architecture is same as target's.

And if I don't then standard "cd $(@D); make install" or anything
similar will be used? Somehow it works without explicit install
command specification.

Due to the way v86d configure is written GENTARGETS seems to be more
proper - I got convinced.

What I have in the patch I provided, was tested build-wise on i386 and
x86-64 targets (but the program itself was only tested in 32bit mode).
I tried that Thomas suggested (redefine CFLAGS), it did not work. I
don't see much sense in changing the working command from what is in
my patch.

Thanks.

  No, with GENTARGETS the install commands are empty by default.  Or you sure
it's not the old binary from a previous compilation that you see in your
target dir?

  I tried it with a clean build and there's no v86d or testvbe in the target
dir.

  The non-existent MAKETARGETS would be even better :-)

  Sure, it's OK as it is (except for the install target of course).
Merely pointing out an alternative.

Thanks, but I'll stay with what I have.

I am resending the patch - hopefully it is good t go now.

Can you try using $(TARGET_CONFIGURE_OPTS) instead, so that CFLAGS and
al. are also passed?

Something like:

	$(MAKE) $(TARGET_CONFIGURE_OPTS) CFLAGS="$(TARGET_CFLAGS) -D__i386__" -C $(@D) all

I'm a bit surprised by the -D__i386__, because this is normally defined
by the compiler. Why is it needed?

See:

thomas at skate:/tmp$ cat toto.c 
#ifdef __i386__
#error "You are on x86"
#elif defined(__x86_64__)
#error "You are on x86-64"
#elif defined(__arm__)
#error "You are on ARM"
#endif

This patch some was discussed some time ago:

http://lists.busybox.net/pipermail/buildroot/2012-May/053825.html
http://lists.busybox.net/pipermail/buildroot/2012-May/053790.html
etc.

and other discussion in May. My initial patch missed installation
instructions, but that was fixed.

and I thouhgt we reached agreement.

Because of manually-written Makefile which somehow does not let these
flags through. I tried many ways.

I submitted this patch in May after many iterations, and I believe it
was just lost in space because of preparations for the May release.

http://lists.busybox.net/pipermail/buildroot/2012-May/053824.html

I am just resubmitting it again.

Thanks.

We generally use capitals for variable names. Also, this can be shortened to

    X86EMU = $(if $(BR2_i386),n,y)

But you don't used the CFLAGS variable. Please correct the comment.

Thanks for your persistence.

This is a local variable - still uppercase?

A http URL would be more friendly to those behind strict firewalls. Even 
better, the website you linked to above seems to offer a tar.bz2 archive of 
the package source.

In this case, just define V86D_CONFIGURE_CMDS, and use GENTARGETS instead of 
AUTOTARGETS, which in not appropriate for this package. Then, you won't need 
this V86D_REALLY_RUN_CONFIGURE hack.

Also, having the configure step above the build step looks more natural to me.
