Sandra Loosemore <sandra at codesourcery dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |sandra at codesourcery dot com --- Comment #7 from Sandra Loosemore <sandra at codesourcery dot com> --- Trying to build an arm-none-linux-gnueabi cross from mainline head, I'm getting this error now: /scratch/sandra/arm-fsf/src/gcc-mainline/libquadmath/libquadmath.texi:369: @include `libquadmath-vers.texi': No such file or directory. /scratch/sandra/arm-fsf/src/gcc-mainline/libquadmath/libquadmath.texi:374: warning: undefined flag: BUGURL. Reverting the patch from r216027 makes it work again. I don't see anything named BUILD_LIBQUADMATH coming out of configure, but in config.log I do see: BUILD_LIBQUADMATH_FALSE='' BUILD_LIBQUADMATH_TRUE='#' Are you sure that this patch was actually tested with a clean build directory where libquadmath-vers.texi was not already present from a previous build?
