While searching for the patch I found out that ubuntu is still actively
 maintaining the version polkit 105. So I thought it was worth using 
all Ubuntu patches in ptxdist as well.

But it might not be the 'ld' in $PATH. So probably something like this is
necessary:
`gcc -print-prog-name=ld` -v | grep -q GNU

Perhaps this one can help you:

This one is also nice:

I know this fact. We are currently using different ptxdist versions up to ptxdist-2014.08.0 for the different BSP projects.

The LLVM linker is also called 'ld'. We need to check for the version string, which contains either "LLVM" or "GNU". If somebody can point me to a few places where to add this check, I can write something in the beginning of next week.

Btw.: Does somebody know a good autoconf howto? In the past years I've tried to avoid using it as best as I can, but this seems to require some autoconf knowledge ;-)

The used PTXdist version to build the toolchain is *independent* from the 
PTXdist version you can use for your BSP project.
And all PTXdist versions can co-exist on your host filesystem.

Here is the source of your problem. I originally added this because it some
really unnecessary dependencies for something in the toolchain.

Maybe we can only add it for the GNU ld? I'm not quite sure how to test for
this, because we need to check the linker called by the host compiler which
may not be 'ld'.

For this project, I need to stick with ptxdist-2013.12.0 for building OSELAS toolchain 2013.12.2.

I've performed a simple grep and stripped out the wrapper and exec lines from the logfiles. This grep searched in the installed ptxdist, the ptxdist sources and the OSELAS sources, as I'm not quite sure, if it is coming from ptxdist or OSELAS toolchain project. But I tend to blame ptxdist ;-)

Remember: The compilation of host-zlib within the OSELAS toolchain project fails.

Which ptxdist version are you using? At least for target packages we set it
in the right place. For me it looks like this:
[...]
wrapper: /usr/bin/icecc arm-v7a-linux-gnueabihf-gcc  -Wl,--as-needed -isystem [...]/platform-arm-hf/sysroot-target/include -isystem [...]/platform-arm-hf/sysroot-target/usr/include  -O3 -D_LARGEFILE64_SOURCE=1 -DHAVE_HIDDEN -o minigzip minigzip.o -L. libz.a -L[...]/platform-arm-hf/sysroot-target/lib -L[...]/platform-arm-hf/sysroot-target/usr/lib -Wl,-rpath-link -Wl,[...]/platform-arm-hf/sysroot-target/lib -Wl,-rpath-link -Wl,[...]/platform-arm-hf/sysroot-target/usr/lib
[...]

The wrapper script adds it before the other options.

I'm not sure where the "-Wl,--as-needed" is comming from. The only thing
that is added at the end of the command-line is PTXDIST_HOST_LDFLAGS and
that's just the -L / -Wl,-rpath stuff.

So we could check for the version.

You are right. I just cross-read an article and got the information wrong. According to the GNU ld man page [1], --as-needed affects the DT_NEEDED flag only of dynamic libraries given _after_ --as-needed. As ptxdist sets it as the very last flag (see below), it is a useless flag.

Hmm, "-Wl,--as-needed" should not be added implicitly and ptxdist should
only add it for target packages if PTXCONF_TARGET_LINKER_AS_NEEDED is set.

If you start ptxdist with '-v' then all calls to the compiler and linker
are logged. Look for lines starting with 'wrapper:' in the logfile.

You need to install a lot of GNU tools from exteranl sources (homebrew, MacPorts, Fink), so I do not see any problem in including bash into this list. My bigger problem is now, that there is no GNU linker available on OS X, so you need to use the LLVM linker which does not understand the -Wl,--as-needed flag. I need to dig deeper to understand since when GNU gcc set this flag by default and what the drawback is, if we remove this flag from the PTXDIST_HOST_LDFLAGS.

So you'll be stuck with the old version. Let's see if we can stay
compatible.

As you might have guessed, Bash 3.2 was the last version to be released under the GPLv2 license, and Apple will not distribute any software covered by GPLv3.

Thank you very much for the explanation. I've never heard or read about
this feature before.


> I don't know why the bash in Max OS X cannot handle this. Maybe it's too
> old? What version are you using?

Your assumption is right. My OS X is 10.9.5 (Mavericks) and way newer
than the Ubuntu 10.04.4 which is the oldest system where I use ptxdist
for my day-to-day work. That's why I didn't took the version numbers
into account. But I was wrong:

Ubuntu 10.04.4: bash 4.1.5(1)-release
OS X 10.9.5: bash 3.2.53(1)-release

Just for completeness: The redirection feature with the optional left
hand {var} notation was introduced in bash 4.1-alpha (see
http://git.savannah.gnu.org/cgit/bash.git/tree/CHANGES#n1550).

bash 4.1 was released on 31 Dec. 2009. :-)

I've installed a recent bash 4.3.33 via homebrew instead. But this is
only part of the fix, because the ptxdist' scripts have a hardcoded
shebang to /bin/bash.

Additionally I needed to replace the Apple bash:
# mv /bin/bash /bin/bash.apple
# ln -s /usr/local/bin/bash /bin/bash


Here is also a potential fix for the configure script to check for a
proper bash version. I've never worked with autoconf, so please check
the patch carefully.

This problem seems to be solved now.

I'm now facing the problem, that host-zlib is not getting compiled with
the compiler setup in ptxdist setup. But this is part of another story
coming soon.

It's valid bash syntax. A bit of history here:
The standard for sh shells says, that the file descriptors up to 9 can be
used inside the shell scripts. So that's what we used originally: With
"5>&1" we create a file descriptor that we can later use to write to stdout
when the normal stdout is redirected to the log file.
However this solution as a problem: oder scripts can use the same file
descriptor numbers and the output is send to the wrong place. This happened
e.g. with configure scripts. So we changed it to:
"exec {PTXDIST_FD_STDOUT}>&1". This is valid in bash and means that a new
file descriptor is opened (with a currently unused number >= 10) and
anything written to it is send to stdout. The file descriptor number is
stored in the specified variable (PTXDIST_FD_STDOUT).

I don't know why the bash in Max OS X cannot handle this. Maybe it's too
old? What version are you using?
Maybe something like this works:
exec 7>&1
exec 8>&1
export PTXDIST_FD_STDOUT=7
export PTXDIST_FD_STDERR=8

Michael

I'm not quite sure, if this is clear or not, but the simple dollar sign is not the fix. If adding the dollar sign to convert the brace expansions to parameter expansions, the next error is in the last line of the function:

> ${logout}: ambiguous redirect

So I'm still searching for explanations on why there are brace expansions and why the work in Ubuntu's bash, but not in Apple's bash.

[ptxdist] (no subject)

[Rüdiger, Christoph]

Hello,

I'm trying to use ptxdist on a Mac OS X system to get rid of the Linux VM just for compiling things. Here is the thing I stumbled upon because I don't get the intention and therefore struggle to find a patch.

The git commit 0dc57566bc5a25d2b086de333844a3c00addf0e4 from 2012-12-13 changed the body of the ptxd_make_log() function in scripts/libptxdist.sh from this implementation

-ptxd_make_log() {
-       #
-       # fd3 == stdout to logfile
-       # fd4 == stderr to logfile
-       # fd5 == clean stdout
-       # fd6 == clean stderr
-       #
-       {
-               export PTXDIST_FD_STDOUT=5
-               export PTXDIST_FD_STDERR=6
-               export PTXDIST_FD_LOGFILE=7
-               {
-                       if [ -z "${PTXDIST_QUIET}" ]; then
-                               ptxd_make "${@}" 4>&- |
-                               # make's stdout on fd0
-                               tee -a "${PTX_LOGFILE}" 2>&4 4>&- 5>&- 6>&-
-                               check_pipe_status || return
-                       else
-                               exec 4>&-
-                               ptxd_make "${@}" 1>> "${PTX_LOGFILE}"
-                       fi
-               } 2>&1 1>&3 3>&- 7>> "${PTX_LOGFILE}" |
-               # make's stderr on fd0
-               tee -a "${PTX_LOGFILE}" 1>&2 3>&- 4>&- 5>&- 6>&-
-               check_pipe_status || return
-       } 3>&1 4>&2 5>&1 6>&2
-}

to this implementation

+ptxd_make_log() {(
+       # stdout only
+       exec {PTXDIST_FD_STDOUT}>&1
+       # stderr only
+       exec {PTXDIST_FD_STDERR}>&2
+       # logfile only
+       exec 9>> "${PTX_LOGFILE}"
+       export PTXDIST_FD_STDOUT
+       export PTXDIST_FD_STDERR
+       export PTXDIST_FD_LOGFILE=9
+
+       if [ -z "${PTXDIST_QUIET}" ]; then
+               # stdout and logfile
+               exec {logout}> >(tee -a "${PTX_LOGFILE}")
+       else
+               # logfile only
+               exec {logout}>> "${PTX_LOGFILE}"
+       fi
+       # stderr and logfile
+       exec {logerr}> >(tee -a "${PTX_LOGFILE}" >&2)
+
+       ptxd_make "${@}" 1>&${logout} 2>&${logerr}
+)}


Now, my bash is complaining at the first exec command:

> exec: {PTXDIST_FD_STDOUT}: not found


To me, it looks fully understandable, because {PTXDIST_FD_STDOUT} is an ill-formed brace expansion and is therefore ignored. But why is the Linux (Ubuntu 12.04) not complaining about?

What is the intention of this brace usage here?

However, an
> echo a{b,c,d}e
expands on both machines to "abe ace ade" and an
> echo {logout}
gets ignored on both machines. Output is just "{logout}".

Best regards,
Christoph

Sorry for leaving the subject empty, I blame my nose sneezing the whole

No functional changes, just some smaller "beautifications":
- Package brings own init scripts for sysv and systemd now
- install_tree is used instead of find + install_copy
- some dependencies have been added, expecially QT4_DECLARATIVE
- squashed into one commit
