Trying to compile qemu on amd64 based Solaris.
I do not have write permission to /usr/local subtree
./configure --libdir=other-path --prefix=not-ustlocal
is fine
but make always generates binaries that want to find
/usr/local/lib/libSDL-1.2.so.0 etc. (checked with ldd).
What is the way out for this sticky point?

Well, the problem is I do not root privileges so can't place libSL in
/usr/local/lib or /usr/local/lib/amd64.
I would like to keep it in $HOME/lib and want qemu to see the lib
archive.
I will try LD_LIBRARY_PATH option. Is to possible to have a staticly
linked version of libSDL in the qemu binaries?

Where is the problem 64bit versus 32bit ?
(32 bit version of libSDL-1.2.so.0 found while amd64 64bit version needed?)
(should go under /usr/local/lib/amd64/libSDL-1.2.so.0)

Read ld.so.1(1)
i.e.
# man ld.so.1
Then: One option is to set $LD_LIBRARY_PATH (or potentially
$LD_LIBRARY_PATH_64 [not required]).
bash:
# export LD_LIBRARY_PATH=/export/home/me/foo/mypersonallibs:$LD_LIBRARY_PATH
Did you set ./configure --prefix=SomeWritableLocation ?

The short answer is NO, not on SunOS >= 5.10 .
Especially not for 64bit.
In particular not for 64bit_amd64.
You will hardly be able to meet the required dependencies.
I'm leaving over the weekend now, much luck with it.

Well, the source compiled after LD_LIBRARY_PATH trick with
correct libSDL dependency, ldd shows this too, but invocation of qemu:
qemu -hda ./minix.img -m 128 -localtime -no-kqemu
results in
[1]+ Segmentation Fault ./qemu -hda ./minix.img -m 128 -localtime -no-kqemu
and
qemu-system-x86_64 ./minix.img -m 128 -localtime
results in a
QEMU[Stopped] window
The HD image minix.img does boot correctly on a Linux machine.
Also, I downloaded the SDL-1.2.11 source from opensolaris.org download
page. I can't figure out how to apply the 64bit patch (patch rejects the
diffs, a visual inspection shows that patch is already applied to the
source?)

Manually add "-L/usr/local/lib -R/usr/local/lib" to the Makefile for the link
phase so it will correctly add those paths to the library lookup. If I had
a code base to look at this instance, I could tell you where. You could
also add those flags to Makefile.target in the SOLARIS specific areas,
which would probably make more sense.
As Martin indicated, setting LD_LIBRARY_PATH may get you a running
binary, but LD_LIBRARY_PATH is the wrong answer for Solaris.

Because I doubt, an amd64 version of libSDL is currently present in
/usr/local/lib/amd64
(and he doesn't have w access).
This method is btw not really "new" to me, see my posting from a few
hours ago:

--->> Weak statement.
It has its [dis]advantages.
Namely that the paths to a library are _not_ hardwired.
That's the exactly reason, why I did recommend it in this very scenario.
And I would do it again for Ishwar's current needs.

Manually applying a patch will always work (vi or emacs -nw)

My answer had been a bit longer:
"Read ld.so.1(1)
i.e.
# man ld.so.1
Then: *One* option is to set $LD_LIBRARY_PATH (or potentially
$LD_LIBRARY_PATH_64 [not required])."

I'm not saying it doesn't work. But properly compiled programs for
Solaris include the run time paths to the libraries so an LD_LIBRARY_PATH
environment variable is not required.
LD_LIBRARY_PATH is interesting to test out new versions of support
libraries without actually having to recompile, so it has it's uses.
but too often, folks use LD_LIBRARY_PATH as a panacea on Solaris
to fix poorly compiled programs.

He is experimenting and trying out a bit.
Not building to be published packages.
I advised him to read and understand ld.so.1(1).
And I mentioned $LD_LIBRARY_PATH as *one* possible option for him to get
quick results.

Right. I knew what I meant, I just didn't type it right.

LD_LIBRARY_PATH is the wrong answer for Solaris. It's great for
trying to fix problems like this when the app won't run with a particular
set of libraries, or you're testing with new libraries and you don't
want to recompile (I've done this before). Too many people use
it as a panacea for poorly compiled/configured Open source software.
In this case, he might just set the LD_LIBRARY_PATH and never
recompile it, even though it won't work if it uses the default LIB path.

But then that requires a dependency on knowing where your
libraries are, and could possibly create an imcombaility by
overriding a library path for some other application that is
also leaning on LD_LIBRARY_PATH. Obviously you can
get around this by encapsulating each application requiring
LD_LIBRARY_PATH, thereby negating the need for a user
or system wide LD_LIBRARY_PATH variable.
> That's the exactly reason, why I did recommend it in this very scenario.
In this case, I can agree for the purposes of a test. But it also indicates
that some work is required for the Solaris port if other library paths
need to be linked in during the compliation/link phase.

Works for me.

It should work. the main thing is to not to agressive with LD_LIBRARY_PATH in
this case. Since it sounds like it already may be linking against /usr/local/lib
where the current libSDL is, you should just be able to add the new lib dir
to the LD_LIBRARY_PATH env variable, and then run ldd on qemu to make
sure it's finding the right libraries. When you have the right LD_LIBRARY_PATH,
then it should be working for you.
> Is to possible to have a staticly

There is an option for statically linked libSDL in the qemu binaries,
and I tried to make sure I kept that intact for solaris in the configure
script. Try it and see what happens.

Can you point the areas? (I only found one
ifdef CONFIG_SOLARIS
LIBS+=-lsocket -lnsl -lresolv -L/home/faculty/r/rattan/solqemu/lib -R/home/facul
ty/r/rattan/solqemu/lib
endif
)
and it does not make a difference.
