[PATCH] configure: Add flags for MinGW32 standalone build

[PATCH] configure: Add flags for MinGW32 standalone build

[Joshua Watt]

There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
 1) A standalone distribution, where QEMU is self contained and
    extracted by the user, such as a user would download from the QEMU
    website. In this case, all of the QEMU files should be rooted in
    $prefix to ensure they can be easily packaged together for
    distribution
 2) QEMU integrated into a distribution image/sysroot/SDK and
    distributed with other programs. In this case, the provided
    arguments for bindir/datadir/etc. should be respected as they for a
    Linux build.

Add a configure time flags --enable-standalone-mingw and
--disable-standalone-mingw that allows the user to control this
behavior. The flag defaults to "enabled" if unspecified to retain the
existing build behavior

I think this should maybe be done independently from MinGW, so that it could 
be used on other systems, too. Thus maybe rather name the switch 
"--enable-standalone-distribution" or "--enable-standalone-installation" or 
something like this? On MinGW, the value of the switch could then default to 
"yes" while on other systems it would be "no" by default.

We could, but I'm curious how useful that is? Does that make the option 
just a shorthand for "--mandir=$prefix --bindir=$prefix 
--datadir=$prefix etc..." for all builds?

Yes, that would basically be a shorthand for that. Could be useful for 
people who want to create standalone binaries on Linux etc., too.

Aren't nearly all files already rooted in $prefix? The only exception I 
know is /etc/qemu.

Rooting in $prefix still allows hierarchical subdirectories. I'd prefer 
them for MinGW, too.

I agree, it was an issue before 5.2 but now we have relocatable 
installations.  So it would be better to remove all the special casing 
of mingw, except that (for backwards compatibility) on mingw bindir 
defaults to $prefix instead of $prefix/bin.  Then Joshua's usecase is 
covered simply by --bindir=/mingw/bin.

Right. Removing the special case for MinGW would solve my problem and
be fine with me; the thing I don't know is if we need to preserve the
backward compatibility of forcing a specific "flat" layout in $prefix
when building for MinGW. There are basically 2 options I can see:
 1) Add a flag to default MinGW to the "flat" layout, but allow it to
be overridden so that it can follow a normal layout (e.g. --bindir,
etc. are respected). This what my patch adds
 2) Remove the special casing for MinGW entirely. A "flat" layout
would still be possible by doing e.g. "--bindir=$prefix
--datadir=$prefix ..." manually but it would no longer be the default.

I'm fine with either option, but I'm not familiar enough with the
project to be able to know which is better.

I think it's okay if you remove the special case _almost_ entirely. 
That is, MinGW would still default to --bindir=$prefix (and that would 
be the only "flattened" directory), but it would be possible to override 
it for your use case.

[PATCH v2] configure: MinGW respect --bindir argument

[Joshua Watt]

There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
 1) A standalone distribution, where QEMU is self contained and
    extracted by the user, such as a user would download from the QEMU
    website. In this case, all the QEMU executable files should be
    rooted in $prefix to ensure they can be easily found by the user
 2) QEMU integrated into a distribution image/sysroot/SDK and
    distributed with other programs. In this case, the provided
    arguments for bindir/datadir/etc. should be respected as they for a
    Linux build.

Restructures the MinGW path configuration so that all of the paths
except bindir use the same rules as when building for other platforms.
This satisfies #2 and #1 since these files do not need to be directly in
$prefix anyway.

The handling for --bindir is changed so that it defaults to $prefix on
MinGW (maintaining the compatibility with #1), but if the user specifies
a specific path when configuring it can also satisfy #2.

Yes, I think this makes most sense, thanks for the update!
