[ptxdist] Using PTXdist on Mac OS

[ptxdist] Using PTXdist on Mac OS

[Bernhard Walle]

Hello,

on a rainy Easter Monday I wrote some small HOWTO that describes the
pitfalls of using PTXdist on Mac OS. It is based on the Generic SDK
using Qemu.

The HOWTO is available at http://www.bwalle.de/docs/ptxdist_mac.pdf, the
LaTeX sources are at https://bitbucket.org/bwalle/ptxdist-macos-doc.

Maybe it can be linked somewhere in the official documentation or at the
website? If something is wrong or missing, drop me a note.


Regards,
Bernhard

Rainy weather seems to be a motivator for writing documentation. :)

If you promise to keep the document at your website at the given URL, I would 
add it to the Guru manual. 

You mentioned your 'https://bitbucket.org/bwalle/ptxdist-arm-boards' BSP in 
you document. I would like to add it to our list of free BSPs 
at "http://www.pengutronix.de/oselas/bsp/pengutronix/index_en.html" if you 
send me some information about its features (to give the reader the same 
overview like with our free BSPs).

> If something is wrong or missing, drop me a note.

Just a few things that confuse me when I read it the first time. I will send 
you a patch (offlist) with my suggestions.

Juergen

I have some things to say about your HowTo (some patches may follow).

a) Fink is _not_ Debian based but uses the great Debian package format
(*.deb ;)
b) FSF GCC is _not_ required for GNU Toolchain bootstrap, I did compile
my arm-cortexa8, arm-v4t, arm-v5te, x86_64 and avr32 OSELAS.Toolchain with:

Well, depends on what you call 'Debian-based'. I didn't say that the
packages are from Debian (the MacPorts packages are also not from
Free/Open/NetBSD).

finkproject.org says "Fink uses Debian tools like dpkg and apt-get to
provide powerful binary package management. " So is the wording

Is following acceptable?

------------------------------------ 8< ------------------------------------
  \item \textbf{Fink} (\url{http://www.finkproject.org}) uses the package
    management tools and the package format from Debian.  Contrary to
    MacPorts, it has both binaries and can be built from source (but as far as
    I know, the binaries are less up-to-date compared the source packages).

This experience is from the time when I used Xcode 4.2 (I had to wait
for the update until MacPorts got support for it). I got llvm-gcc
segmentation faults and this was also "documented" in the bug tracker of
FSF GCC. And I think that in LLVM bugtracker was a fix already in SVN of
LLVM GCC.

I'm just running a build of a toolchain with Xcode 4.3(.2) LLVM GCC and
if that build succeeds then I will remove the restriction to FSF GCC and
mention Xcode 4.3 somewhere in the requirements.

I don't think that some Fink environment settings fixes GCC segmentation faults.
But we will see.

Patch is applied, thanks. But I will wait for Jürgens comments until I
upload a new PDF.

sounds way better than 'Fink is based on Debian.'

well my '(LLVM build 2336.1.00)' used to work. This f*** App Store does
not automagically update X Code as it used to in prior versions of Mac OS X.
Cause I have not encountered llvm-gcc segfaults in my X Code 4.2.1
(build 4D502), I think it is a specific problem to your version. Maybe
mention your version and/or the specific error in your doc?
BTW: Thank you for the pointer to X Code 4.3.2, download is running.
Hopefully no faulty toolchain ...

With Xcode 4.3.2 compiler it works. I checked the armv5 toolchain and
cortexa8 which uses gcc-linaro.

So I'll remove the section about gcc-apple, but I need to check first if
Qemu also works with llvm-gcc or maybe clang.

I think all comments are integrated now. I uploaded a new PDF version
at http://www.bwalle.de/docs/ptxdist_mac.pdf. Thanks to Jürgen and
Andreas for the feedback. The Changelog can be viewed with GIT
at https://bitbucket.org/bwalle/ptxdist-macos-doc, the PDFs are tagged.

Dear Bernhard,

First of all thanks for the great work on porting ptxdist to mac! Since 2010 I tried using it from time to time on my mac, but alway went back to our Linux compute servers for one reason or an other.

I'm using a "quiet modified" version of 10.6 (python27, ncurses, coreutils, git, and several others form macports). So my system is probably not a reference system at all. But 

So, following your your document I end up with a working tool-chain, a working qemu-arm-softmmu and a working kernel, but no hdd img.
I had to fix 
.../lib/ptxdist-2012.04.0/scripts/genhdimg
replacing seq by gseq. But the better approach may be a symlink in .../lib/ptxdist-2012.04.0/bin/

The next point is concerning the files system on a Mac. AFAIR the default filesystem is the case insensitive version of HFS+ (this is definitely true up to 10.6). So the OSELAS tool-chain rejects to build. And further on some of the packages will also fail. Obvious, there are two solutions. Using an external disk with a case sensitive file system (e.g. HFSX, ext*) ore using a (sparse) image as a container. I decided to use the latter approach.

The last point I tumbled over is the git command on page 10:
% git am git clone git://git.qemu.org/qemu.git
Whats the purpose of this command? Is it really needed?

An other thing is xargs ... without the gnu version make distclean fails. The solution is to symlink in .../lib/ptxdist-2012.04.0/bin/, too.

Finally I added two patches to reflect these changes. May be the second patch (Makefile.in) still needs some work to be in its final state. I am not sure, in which make targets the

Well, genhdimg is the only user of 'seq', so I'd rather fix that. Would you
care to send a patch?

It's "make clean" actually and that will remove the relevant symlink.

But gseq is not available on Linux. So I think adding it to the
configure check is the only reasonable approach?

That one is already in ptxdist, after 2012.04:

Maybe just -exec ? Maybe it is a bit slower? But see above.

Indeed, I missed that in the documentation. I'll add it soon. I
personally use the 3rd approach: A data partition on the internal disk
with a case insensitive file system.

I'll send you a personal mail for proofreading if that is okay.

You only need that if you want to use Qemu to start the image.

Well, whats the advantage of $(seq 4) over "for i in 1 2 3 4; do ..." ?

Alternatively, it is possible in just a few lines of code to check for seq or gseq within genhdimg.
SEQ=$(which seq 2>/dev/null ||which gseq 2>/dev/null)
if [[ -z $SEQ ]]; then
some error
exit 1
fi

For this reason I used the second line, starting with patch ...
But the first line is either syntactically not correct or not needed? If I am right, "git am" requires a patchset?

Yes it's there, and calling "make clean" twice still breaks.

From my point of view removing -r and adding -f is a simple, but sufficient solution. I added the corresponding patch, along with a patch fixing a typo in configure.ac.

So "find -print0" works, right? I wasn't sure if that's a GNU extension.
The xargs man-page I have says "... The GNU find -print0 option produces
input suitable for this mode.". So I wasn't sure if this works _only_ with
GNU find.

yes, OS X delivered BSD find supports -print0, but it does _not_ support
omitting the path!

Therefore the provided patch from Michael will _not_ work with that find.

Beside that that was not the question. I think a portable solution would be:

This one is my promoted solution in yesterdays patch, except I would recommend 'rm -f' to avoid errors if find returns an empty list.

well ok, +1 for your solution. I maybe missed that in my mail history
(can you please send patches inline next time?).

is this the preferred method?

As I'm using Mail.app (Apple Mail) I'm alway fearing broken patches when sending inline, as the program is set up to do automatic line breaks. And up to now I can get git send-email to play with our universities smtp server.

Yes, it makes reading and commenting the patch much easier.

Most patches get at least one round of review before I really test them.
If it fails to apply, then I'll say something and you can attach the next
version.

as Michael said it is much better to read.

(line break also broken, fix your MUA ;)

You could use a wrapper for git send-email. Some use msmtp to work
around broken/insufficient smtp support in git. There are some git +
msmtp + gmail howto's in the web, maybe that can solve your problem with
your servers?

I would also not recommend using Apple Mail for sending patches. Even
for Thunderbird (which can be configured to do everything right) it's a
mess to do so.

If you don't want git send-email directly, you could consider using git
imap-send. This one puts the formatted mails in the drafts folder of
your IMAP server and you can actually review and send the mails using
Apple Mail. However, I would guess that this produces better results
than just using copy and paste.

Re: [ptxdist] Using PTXdist on Mac OS 10.7

[Daniel Kriesten]

[-- Attachment #1.1: Type: text/plain, Size: 1945 bytes --]

Dear all,

So today I did a fresh build of ptxdist on my mac using
Mac OS X 10.7.5
XCode 4.5.2 (4G2008a)

and (nearly) following the guide of Bernhard. Only, I use the git-Version as of today (08f738f9).

In addition to the tools mentioned in the guide, I had to install autoconf and automake.

Then I did:
./autogen.sh 
./configure --prefix=/usr/local/ptxdist --with-bash-completion=/usr/local/etc/bash_completion.d
make

This ends in the following error:
----- 8< -----
gcc -g -O2  -DCURSES_LOC="<curses.h>" -DKBUILD_NO_NLS -DPACKAGE='"ptxdist"' -DCONFIG_='"PTXCONF_"' -c mconf.c -o mconf.o
mconf.c: In function ‘search_conf’:
mconf.c:378: error: invalid initializer
make[1]: *** [mconf.o] Error 1
make: *** [kconfig] Error 2
----- >8 -----

Happily, clang is more nosy on the error:
----- 8< -----
clang -g -O2  -DCURSES_LOC="<curses.h>" -DKBUILD_NO_NLS -DPACKAGE='"ptxdist"' -DCONFIG_='"PTXCONF_"' -c mconf.c -o mconf.o
mconf.c:378:25: warning: implicit declaration of function 'CIRCLEQ_HEAD_INITIALIZER' is invalid in C99 [-Wimplicit-function-declaration]
                struct jk_head head = CIRCLEQ_HEAD_INITIALIZER(head);
                                      ^
mconf.c:378:18: error: initializing 'struct jk_head' with an expression of incompatible type 'int'
                struct jk_head head = CIRCLEQ_HEAD_INITIALIZER(head);
                               ^      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 warning and 1 error generated.
----- >8 -----

So the solution is to add "missing.h" to mconf.c, when compiling on a mac. But I'm not sure, what's the pretty way to do that in a platform independent way. But I'm sure you may lend me a hand here?

${PTXDIST_TOPDIR}/bin/xargs should be a gnu xargs. Is that not used?

Just include it unconditionally "missing.h" only defines things that are
actually missing. If it breaks anything, then it's a bug in "missing.h".

It  is used, if it already exists. But on a system, where gnu xargs is not the default (like Mac), something like
./configure
make clean

or
./configure
make
make clean; make clean

fails, due to missing xargs with GNUoption -r
