For completeness sake I wanted to follow up my own question, now that I found the solution. It appears that the CT_CC_CORE_EXTRA_CONFIG and CT_CC_EXTRA_CONFIG options also need to include --with-float=softfp, so they now look like this: CT_CC_CORE_EXTRA_CONFIG="--with-fpu=neon --with-float=softfp" CT_CC_EXTRA_CONFIG="--with-fpu=neon --with-float=softfp" For details on where I found the solution (from Linaro and Ubuntu notes), see my blog entry: http://www.graphics-muse.org/wp/?p=839 Hope that helps anyone else who runs into the same issue. -- Michael J.
