Thanks, Jessica 25135 4 david.nystrom 2012-09-13 05:49:26 +0000 Laurentiu Serban, asked me to followup, so here it goes: In cases where toolchains are created with ${DISTRO} != "poky", this nullpointerexception is seen, This patch has already been merged to master, and judging by the git tags, will be apart of the 1.3 release I guess. Br, David 25211 5 jessica.zhang 2012-09-13 18:47:27 +0000 fixed by commit: http://git.yoctoproject.org/cgit.cgi/eclipse-poky/commit/?id=26692a18a8245561cefcab1402b93b6325c36bed 27258 6 alexandru.c.georgescu 2012-11-06 14:40:17 +0000 Hi David, I am trying to verify this bug but I need some additional details. Can you tell me what exact distro are you using, and also what eclipse plugin version you were using? Thanks, Alex. 27270 7 bjorn.arnelid 2012-11-07 06:42:04 +0000 This bug is fixed in yocto plugin 1.3. It was a problem using yocto plugin 1.2 and earlier on any version of eclipse running on any version of Linux. As David described you need to create a toolchain where ${DISTRO} is something other then "poky" to get this error. I first encountered this bug using eclipse 3.8.1, Yocto plugin 1.2 on Ubuntu 12.04 LTS 27299 8 alexandru.c.georgescu 2012-11-07 17:03:19 +0000 Tested with 78983e939ab17f02f8911c8b0d0e326b419856b9 on master. In order to verify, I modified the DISTRO to be other than poky. To do so, the following have to be modified in poky: 1. chose a name different than poky for DISTRO, e.g: pob 2. Change in conf/local.conf DISTRO = "poky" to: DISTRO = "pob" 3. Copy meta-yocto/conf/distro/poky.conf to meta-yocto/conf/distro/pob.conf 4. In meta-yocto/conf/distro/pob.conf change the following parameters to other than standard, for ex: DISTRO = "pob" SDK_VENDOR = "-pobsdk" TARGET_VENDOR = "-poby" This way the folders under sysroots after sdk is installed will have a different name than "-pokysdk-linux" 5. Source the poky environment: $ source oe-init-build-env 6. Build the standalone toolchain: $ bitbake meta-toolchain-sdk 7. Install the resulted toolchain. In the latest eclipse (juno) with the latest plugin (http://autobuilder.yoctoproject.org/pub/nightly/20121102-2/eclipse-plugin/) the standalone toolchain created can be imported and used to create and build a new helloworld project. In eclipse indigo with the 1.2 eclipse plugin release (http://downloads.yoctoproject.org/releases/eclipse-plugin/1.2) and the above toolchain created does not exactly show me a NullPointerException but when pressing OK, a popup window appears and disappears immediately and then the Yocto Project ADT window closes without saving the changes. Given that using the fix and latest eclipse-plugin and eclipse juno I could build successfully a Hello World application, we can close the bug.
