eclipe-yocto: SDKTARGETSYSROOT not being expanded correctly

eclipe-yocto: SDKTARGETSYSROOT not being expanded correctly

[Bryan Evenson]

I am using version 1.6.2 of the Yocto Eclipse plug-in (from http://downloads.yoctoproject.org/releases/eclipse-plugin/1.6.2/kepler/) under Fedora 21.  After some recent issues with getting the plug-in to compile my application, I noticed that I am having a variable expansion problem with CC.

I followed the instructions for building an SDK for my image and I am using the pre-built toolchain.  In the environment script for the SDK, CC is defined as follows:

	export CC="arm-poky-linux-gnueabi-gcc  -march=armv5te -marm -mthumb-interwork -mtune=arm926ej-s --sysroot=$SDKTARGETSYSROOT"

I then generate new a simple Yocto Hello World C project and build the application.  It builds just fine, but I see the following in the console output:

	arm-poky-linux-gnueabi-gcc  -march=armv5te -marm -mthumb-interwork -mtune=arm926ej-s --sysroot=DKTARGETSYSROOT 

However, if I go to Project->Properties->C/C++ Build->Environment and change the CC environment variable to the following:

	arm-poky-linux-gnueabi-gcc  -march=armv5te -marm -mthumb-interwork -mtune=arm926ej-s --sysroot=${SDKTARGETSYSROOT}

then the SDKTARGETSYSROOT is properly expanded to the correct value.  Is anyone else seeing this problem, or is this due to the version of tools that exist on Fedora 21?

Thanks,
Bryan

I just reproduced this bug and opened a bugzilla issue to track it.

Thank you for taking the time to report this issue.

Thanks,
