title: Toolchain configuration for softfp using yocto
body: <p>I have built images for IMX6 Sabersd using yocto as shown below.  </p>
  
  <pre><code>#curl http://commondatastorage.googleapis.com/git-repo-downloads/repo &gt; ~/bin/repo
  #repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.10.53-1.1.0_ga
  #repo sync
  #source setup-environment build
  #bitbake core-image-minimal
  </code></pre>
  
  <p>During build time it is getting the gcc-4.8 source and compiling tool chian for IMX6. The toochain is using hard floating point(checked using "./arm-poky-linux-gnueabi-gcc -v" and output is having "--float-with=hard" ), my requirement is the toolchain has to use softfp.</p>
  
  <p>The reason behind this is I am using 3rd party pre-built libraries, which are not compatible for hardfp. So during compilation time I am getting errors as shown below.</p>
  
  <pre><code>ld: error: *Executable* uses VFP register arguments,  *Library* does not
  ld: failed to merge target specific data of file *Library*
  </code></pre>
  
  <p>Can you help on how I can change the configuration in yocto to compile tool chain with softfp. </p>
  
  <p>I couldn't find which version of yocto freescale is using, but I could see gcc-4.8 recipies under "poky/meta/recipes-devtools/gcc/".</p>
