[yocto] Eclipse-ADT-build-error (Lu, Lianhao)

[Zhang, Jessica]

Hi Andy,



I've made some changes in the eclipse plug-in code that can be more robust for handling user cross development settings that should be included in for 1.1.2 and 1.2 releases.  But in the mean time to solve your issue, instead of pointing your sysroot to "/opt/poky/1.1.1/sysroots" please go one level down to "/opt/poky/1.1.1/sysroots/armv5te-poky-linux-gnueabi" this should resolve your issue for using the ADT 1.1.1 plugin for cross compilation.



Thanks,

Jessica

Lianhao,



I've looked into this more deeply and I'm pretty sure I've followed the directions in the ADT manual correctly as I've gotten this to work before in  ADT v1.1.  I'm having the same problem Lu seems to be having.  To answer your questions:



1. Host OS? - Ubuntu 11.10 - 32bit VM

2. Which version of eclipse?  3.7.2

3. Which version of Yocto eclipse plugin? 1.2.0.2x - I just tried to get it as per the manual but the link on the ADT manual for the plugin is broken.  I was able to use the update feature from within Ecplise - this brought me from 1.1 to 1.2.0.2x

4. Which image do you use as sysroot? core-image-sato or core-image-sato-sdk? - Core-image-minimal

5. Which version of metadata do you use to build the image? Sugarbay - is that what you're looking for?

6. How do you install the toolchain? Using adt-installer or extracting meta-toolchain tarball? If using meta-toolchain tarball, which version do you use? - used the premade tarball from: http://downloads.yoctoproject.org/releases/yocto/yocto-1.1.1/toolchain/i686/poky-eglibc-i686-arm-toolchain-gmae-1.1.1.tar.bz2<http://downloads.yoctoproject.org/releases/yocto/yocto-1.1.1/toolchain/i686/poky-eglibc-i686-arm-toolchain-gmae-1.1.1.tar.bz2>  - once extracted, in Ecplise, I point at /opt/poky/1.1.1 for my Toolchain Root and /opt/poky/1.1.1/sysroots/ for my Sysroot Location.



Following the ADT manual closely, I've sourced the ADT env vars with $source /opt/poky/1.1.1/environment-setup-x86_64-poky-linux



Now, I've opened a new C Hello World template project and use Project -> Reconfigure Project.  Unfortunately this fails.  The console reads "> configure: error: C compiler cannot create executables" as Lu has seen.  All the other Eclipse requirements from the ADT manual have been installed as well.



The config.log shows this snippet as the culprit:

...

Thread model: posix

gcc version 4.6.1 20110627 (prerelease) (GCC)

configure:2413: $? = 0

configure:2402: x86_64-poky-linux-g++ -V >&5

x86_64-poky-linux-g++: error: unrecognized option '-V'

x86_64-poky-linux-g++: fatal error: no input files

compilation terminated.

configure:2413: $? = 1

configure:2402: x86_64-poky-linux-g++ -qversion >&5

x86_64-poky-linux-g++: error: unrecognized option '-qversion'

x86_64-poky-linux-g++: fatal error: no input files

compilation terminated.

configure:2413: $? = 1

configure:2433: checking whether the C++ compiler works

...



So interestingly, I went ahead and tried to run autogen.sh directly from the terminal with "sh autogen.sh" and this also gives me the same error: "configure: error: C compiler cannot create executables"



However, when I run this with sudo in the terminal it works.  I can then call "sudo ./configure" from the terminal and that also works.  Now I have a Makefile in my src directory as expected.  Unfortunately, this project still doesn't build in Eclipse.  I keep getting "no rule for make target 'all' "



I've done all of the above again, fresh, after calling "chmod -R 777 /home/userName/workspace" so it might not be a permissions problem.



I've run through these ADT steps in the 1.1 version of the ADT manual without any problems.  What changed?  Do I submit a bug?
