[ptxdist] qmake broken after ptxdist version switch?

[ptxdist] qmake broken after ptxdist version switch?

[Markus Wolters]

Hello everyone,

I've just switched my ptxdist version from 2012.03.0 to 2013.01.0. When I try to build a qt4 project which build before without any problems, I now get two warnings regarding ld:

/opt/OSELAS.Toolchain-2012.12.1/arm-cortexa8-linux-gnueabihf/gcc-4.7.3-glibc-2.16.0-binutils-2.22-kernel-3.6-sanitized/lib/gcc/arm-cortexa8-linux-gnueabihf/4.7.3/../../../../arm-cortexa8-linux-gnueabihf/bin/ld: warning: libdbus-1.so.3, needed by /home/apollon/ptxdist_V002/platform-phyCORE-AM335x/sysroot-target/usr/lib/libQtDBus.so, not found (try using -rpath or -rpath-link)

Does anyone have an idea what I'm doing wrong/ how to fix this?

Did you re-build the whole project after the PTXdist version switch?

[Markus Wolters]

Yes, I did. 
I just figured out, that providing the necessary libs in my pro file fix the problem. But that can't be the right way to fix it, I think?! And it seems to be no qmake problem...

I think the older qt mkspecs got their include path patched. This changed 
somehow in newer qt versions. So you might need to restore the old behavior 
by copying the old rules sed statement to the new file or add some ptxdist env 
variables.

I have no idea why the pengutronix guys changed the behavior. But i think its 
annoying as you can't just use the right qmake and be happy without env vars.

Are you talking about building Qt project outside PTXdist? If that is the
case then you need to use <BSP>/platform-<something>/sysroot-host/lib/wrapper
in PATH instead of the toolchain.

Re: [ptxdist] qmake broken after ptxdist version switch?

[Markus Wolters]

Hello Michael,

I though choosing the right toolchain isn't "my problem", as I use the ptxdist g++ specs:
".../sysroot-cross/bin/qmake $1 -spec .../sysroot-target/usr/mkspecs/qws/linux-ptx-g++ -r"
Wouldn't it be better to fix it at that point?

Markus

No. The mkspecs only handle things for Qt. The wrapper fix it for everything.

Hi,

unfortunately your solution didn't work for me. I've changed PATH and "which arm-cortexa8-linux-gnueabihf-ld" shows the wrapper path, but the libs still can't be found.

Re: [ptxdist] qmake broken after ptxdist version switch?

[Schenk, Gavin]

Hi Markus,

in order to build and debug QT-Projects outside ptxdist I use a small script to start QT-Creator.
I named the script start_creator.sh and put it into the ptxdist-project.

<content start_creator.sh>
#!/bin/bash

export PTXDIST_CROSS_CPPFLAGS=$(./p print PTXDIST_CROSS_CPPFLAGS)
export PTXDIST_CROSS_LDFLAGS=$(./p print PTXDIST_CROSS_LDFLAGS)
export PTXDIST_PLATFORMCONFIG=$(./p print PTXDIST_PLATFORMCONFIG)
export PATH=$(./p print PTXDIST_PLATFORMDIR)/sysroot-host/lib/wrapper/:$PATH

echo $PATH
echo $PTXDIST_CROSS_CPPFLAGS
echo $PTXDIST_CROSS_LDFLAGS
echo $PTXDIST_PLATFORMCONFIG

/opt/qtcreator-2.8.1/bin/qtcreator
</content start_creator.sh>

Things you have to concern are:
 - Start your creator using this script
 - Build a Kit using the gcc from the wrapper path "e.g.: /var/projects/xxx/platform-xyz/sysroot-host/lib/wrapper " and the qmake from your projects sysroot-cross.

constraints:
You do not see the real gcc name when building your project caused by the wrapper ( You´ll see g++ instead of e.g. arm-v5te-linux-gnueabi-g++ )
You cannot chose the creator version yet, feel free to expand my script and send it back to me :)

I hope this will help you.

Guten Morgen Gavin,

entschuldige, dass ich Dich direkt anschreibe, aber ich hoffe die Kommunikation geht so etwas flüssiger :-)

Wo bekomme ich denn den "./p print " Part von Dir her? Bei mir läuft das Script so leider nicht.

Danke schon Mal,
Markus

Re: [ptxdist] qmake broken after ptxdist version switch?

[Schenk, Gavin]

Hi Markus,

sorry my mistake, I did not explain my example adequately. I answer in english, maybe others need the extra information, too.

I assume, that you put the script "start_creator.sh" into the top directory of your ptxdist project.
In our projects we create a symbolic link to the correct ptxdist version and name this link "p".

<snip>
gschenk@vm621deb-1:~/projects/prodos3/ptxdist$ ls -la
...
lrwxrwxrwx  1 gschenk users    34 Mär 15  2013 p -> /opt/ptxdist/bin/ptxdist-2013.03.0
...
</snip>

The "./p" print of "start_creator.sh" can be replaced by "/opt/ptxdist/bin/ptxdist-XXXX.YY.Z print" (put inyour ptxdist version for XXXX, YY, Z), or you create the link "p" too.

The "print" is just an option to ptxdist. ptxdist --help says:
...
print <var>                     print the contents of a variable, in the way
                                it is known by "make"
...

I hope this helps, good luck!

Best Regards
Gavin Schenk

Re: [ptxdist] qmake broken after ptxdist version switch?

[Markus Wolters]

Thank you Gavin,

your solution solved my general library problem. 
Unfortuantely, the next problem arise right after that. My project consist of own libs and executables, but at linking stage the own build libs are not known anymore (unknown reference). Does this make any sense anyone of you?

Re: [ptxdist] qmake broken after ptxdist version switch?

[Schenk, Gavin]

Hi Markus,

I give it a try. Let´s say you have two packages:

        MYEXECUTABLE
        MYLIBRARY

Both packages come with its own rule/makefile in the rules subfolder of your project.
MYEXECUTABLE builds an executable that depends on the library MYLIBRARY.

First of all you have to describe this dependency in MYEXECUTABLE.in with a line "SELECT MYLIBRARY". As a result of this, MYLIBRARY is build before MYEXECUTABLE.

Secondly, and that maybe solve your problem, you have to install the libraries build by MYLIBRARY in install step (not targetinstall!!!) into the folder $(PTXDIST_SYSROOT_TARGET)/usr/lib or $(PTXDIST_SYSROOT_TARGET)/lib. This is the place the linker searches libraries when linking. In this stage you should copy needed include files to e.g. $(PTXDIST_SYSROOT_TARGET)/usr/include, too.

If you do this correctly you can just use the library seamless in your projects.

1.) Use #include <MYLIBRARY.h> in your code
2.) The linker magically finds your library.

Here an example of an target step.

$(STATEDIR)/qextserialport.install:
        @$(call targetinfo)
        cp $(QEXTSERIALPORT_DIR)/src/build/libqextserialport.so.1.2.0 $(PTXDIST_SYSROOT_TARGET)/usr/lib/
        ln -f -s libqextserialport.so.1.2.0 $(PTXDIST_SYSROOT_TARGET)/usr/lib/libqextserialport.so.1.2
        ln -f -s libqextserialport.so.1.2.0 $(PTXDIST_SYSROOT_TARGET)/usr/lib/libqextserialport.so.1
        ln -f -s libqextserialport.so.1.2.0 $(PTXDIST_SYSROOT_TARGET)/usr/lib/libqextserialport.so

        mkdir -p $(PTXDIST_SYSROOT_TARGET)/usr/include/qextserialport

        cp $(QEXTSERIALPORT_DIR)/src/*.h $(PTXDIST_SYSROOT_TARGET)/usr/include/qextserialport/

        @$(call touch)

@Gurus: Is there a better, smarter way to achive this, like install_lib?

Best regards
Gavin
