[yocto] Yocto and Qt embedded
Hi, This is my first post on this mailing list and I'm quite new to Yocto. I successfully built a distro using the latest release of hob, including Qt embedded (without X11). I wrote a Qt application and cross compiled for ARM on my host machine but when I deploy it on the device (a Freescale iMX53) I get and error because the application looks for libraries like libQtGui but on the distro all Qt libraries are named like libQtGuiE (ending with E which I suppose it stands for Embedded). Is the problem due to a wrong distro configuration or a compile problem? (I'm using a default ARM toolchain from Ubuntu repos) Thanks Giovanni -- Dott. Ing.

Re: [yocto] Yocto and Qt embedded
Hi Jessica, I built separately the qte toolchain running: - bitbake meta-toolchain-qte and the qte demo image (without toolchain) using Hob. Now I need to integrate Yocto SDK and Qt Creator IDE. I'm trying to configure Qt Creator to recognize Poky toolchain and Qt Creator asks for the compiler path inside Poky SDK. Where is the compiler located inside Poky SDK built from meta-toolchain-qte?

Re: [yocto] Yocto and Qt embedded
Hi Khem, I have to use Yocto Denzil branch (not the latest snapshot) because I'm developing for Freescale iMX53 QSB and fsl-arm branch is aligned with Denzil. >From a fresh Denzil installation I edited local.conf and bblayer.conf files and run "bitbake meta-toolchain-qte". The command ends successfully. So I tried to find g++ compiler using "find" command, into: /opt/poky/1.2.1/sysroots/i686-pokysdk-linux/ with no success. I found qmake command (into /opt/poky/1.2.1/sysroots/i686-pokysdk-linux/usr/bin) but when I set this Qt version in Qt creator the ABI detection fails, so I can't configure the right toolchain inside Qt creator and I can't build my application. Do I have to rerun the bitbake command? Am I missing any configuration? Thanks Giovanni -- Dott. Ing.

Re: [yocto] Yocto and Qt embedded
Thanks Khem, I successfully found g++ compiler path which is: /opt/poky/1.2.1/sysroots/i686-pokysdk-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++ now I was able to configure the poky tool chain into Qt creator (using default mkspec which is linux-g++); after that I tried to configure Qt Version (4.7.4) in Qt creator using the following qmake file: /opt/poky/1.2.1/sysroots/i686-pokysdk-linux/usr/bin/qmake Now Qt creator gives me a warning: *"ABI detection failed: Make sure to use a matching tool chain when building"* * * ABI is automatically set to arm-linux-generic-elf and this warning prevents me to select arm tool chain for building my application. Am I using the wrong mkspec? (The other ones seems unsuitable for me..) Thanks Giovanni -- Dott. Ing.

[yocto] Problem building Yocto Hello World demo on imx53QSB
Hi, I need to deploy a C application that I have made on a Freescale iMX53 QSB. First I wanted to test the cross-compilation environment building the Hello World demo but I got some issues. I made the following steps: - download yocto denzil - source oe-init-build-env - edit local.conf and bblayers.conf files - run 'bitbake meta-ide-support' - copied the resultant sdk in /opt/poky - installed Yocto Eclipse plugin - Configured the plugin as following - toolchain root location: /opt/poky/1.2.1 - sysroot location: /opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi When I build the project I get the following error: *Invoking autogen.sh in build directory: /home/gfoiani/workspace/idea-c-application* * * *Command-line environment variables:* * CFLAGS=" -g -O0 -march=armv7-a -fno-tree-vectorize -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a8 --sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi" CXXFLAGS=" -g -O0 -march=armv7-a -fno-tree-vectorize -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a8 --sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi" LDFLAGS=" --sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi" CPPFLAGS=" -march=armv7-a -fno-tree-vectorize -mthumb-interwork -mfloat-abi=softfp -mfpu=neon -mtune=cortex-a8 --sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi"* * * *sh /home/gfoiani/workspace/idea-c-application/autogen.sh --with-libtool-sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi --target=arm-poky-linux-gnueabi --host=arm-poky-linux-gnueabi --build=i686-linux --with-libtool-sysroot=/opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi * *configure.ac:24: error: AC_SUBST: `idea-c-application_CFLAGS' is not a valid shell variable name* *configure.ac:24: the top level* *autom4te: m4 failed with exit status: 1* *aclocal: autom4te failed with exit status: 1* *configure.ac:24: error: AC_SUBST: `idea-c-application_CFLAGS' is not a valid shell variable name* *configure.ac:24: the top level* *autom4te: m4 failed with exit status: 1* *configure.ac:24: error: AC_SUBST: `idea-c-application_CFLAGS' is not a valid shell variable name* *configure.ac:24: the top level* *autom4te: m4 failed with exit status: 1* *autoheader: '/opt/poky/1.2.1/sysroots/i686-pokysdk-linux/usr/bin/autom4te' failed with exit status: 1* *configure.ac:24: error: AC_SUBST: `idea-c-application_CFLAGS' is not a valid shell variable name* *configure.ac:24: the top level* *autom4te: m4 failed with exit status: 1* *automake: autoconf failed with exit status: 1* */home/gfoiani/workspace/idea-c-application/autogen.sh: line 9: ./configure: No such file or directory* * * *Configuration failed with error* * * What Am I doing wrong?

Re: [yocto] Problem building Yocto Hello World demo on imx53QSB
Hi Jessica, downgrading from Ubuntu 11.04 (32 bit) to Ubuntu 10.04 (32 bit) and following the ADT manual procedure HelloWorld demo works. I noticed that ADT creates an armv5 tool chain instead building the toolchain using Freescale layer (because I need to deploy the application on a iMX53QSB) it creates an armv7 tool chain (that is the right processor architecture). Can this create problems? Thanks Giovanni -- Dott. Ing.

[yocto] Yocto .sdcard file missing after build
Hi, I built some images using the latest Yocto release (with Hob) on a Ubuntu 10.04 32 bit, but when the process finishes (with success) I can't find .sdcard files into "*tmp/deploy/images*" folder. Some time ago I built some other images using a Ubuntu 11.04 32 bit and .sdcard files were created properly. Could it be a problem of max file size in Ubuntu 10.04? Another question...sdcard files that I built using Ubuntu 11.04 (32 bit) were about 3 GByte, is there a way or configuration to reduce this size? Thanks Giovanni -- Dott. Ing.

The native library builds properly but it populates the wrong sysroot..I
can find protoc executable into tmp/sysroots/i686-linux but not into
imx53qsb sysroot, hence rebuilding the protobuf library it can't find the
executable..
Which configuration do I have to use to populate the imx53qsb sysroot?
Thanks
Giovanni

Re: [yocto] Yocto and Google Protocol Buffers
Thanks Ross,
Protocol Buffer README file says:
*** Note for cross-compiling ***
*
*
* The makefiles normally invoke the protoc executable that they just*
* built in order to build tests. When cross-compiling, the protoc*
* executable may not be executable on the host machine. In this case,*
* you must build a copy of protoc for the host machine first, then use*
* the --with-protoc option to tell configure to use it instead. For*
* example:*
*
*
*./configure --with-protoc=protoc*
*
*
* This will use the installed protoc (found in your $PATH) instead of*
* trying to execute the one built during the build process. You can*
* also use an executable that hasn't been installed. For example, if*
* you built the protobuf package for your host machine in ../host,*
* you might do:*
*
*
*./configure --with-protoc=../host/src/protoc*
*
*
I think I have to use this last option and point to the executable into the
i696-linux sysroot..
Can I do this overriding do_configure task? Like this:
*do_configure() {*
*./configure --with-protoc=/path/to/sysroot/i686-linux/usr/bin/protoc*
*}*
*
*
I tried this way but I got a "permission denied" error..
*/bin/bash: line 8: ../-libtool: Permission denied*
*| make[3]: *** [install-libLTLIBRARIES] Error 126*
How can I solve this error?
Thanks
Giovanni

Re: [yocto] Usb-serial device support
For me this procedure works: - bitbake linux-imx -c cleansstate - bitbake linux-imx -c patch - bitbake linux-imx -c menuconfig (add usb-serial converter support) - bitbake linux-imx Giovanni -- Dott.

[yocto] Custom splash screen using psplash
Hi, I need to setup a custom splash screen replacing the Yocto logo with a custom image. I generated my logo using make-image script into psplash screen and replaced the previous one in meta/recipes-core/psplash/files folder. Then I run - bitbake psplash -c cleansstate - bitbake psplash and then generate a new image, but during boot I still see the Yocto logo. Which is the right procedure? Does the my custom logo (a png image) have some requirements (i.e. size, colors, etc..)? Thanks Giovanni -- Dott. Ing.

Re: [yocto] Custom splash screen using psplash
Hi Scott, I copied the psplash directory (and replaced the logo with mine) into my own layer but when I run: - bitbake psplash -c cleansstate - bitbake psplash it still builds the sources located into meta-yocto directory and not sources that are into my own layer directory. How can I build a package pointing to a specific folder path ? Thanks Giovanni -- Dott. Ing.
