So, I built the latest poky and created the example recipe with the `DEPENDS` from my recipe and indeed, I see `libquadmath.so` in `sysroots-components/`.

I am really scratching my head now.  I must be missing something silly somewhere...

My build environment is running `zeus`  and the latest `poky` I grabbed is `honister`  Perhaps something changed that I am just overlooking somehow.

I have tried both of the approaches (local.conf and gcc-runtime_%.bbappend/gcc_%.bbappend), still `libquadmath.so` is not being built.

I will keep fiddling but I think we are onto something.

The interesting thing I found is that `libquadmath.so` IS being built for the nativesdk but NOT when I add `DEPENDS = "virtual/${TARGET_PREFIX}compillerlibs"` to my recipe.

Perhaps, because `FORTRAN = ""` is in the gcc_%.bb, maybe that should be something less strict?

I might be screwing up my bbappend too...

My append is in `meta-mylayer/recipes-devtools/gcc/gcc-runtime_%.bbappend`

Which is mapped correctly to $BBFILES n my layers `layer.conf`

guess that will solve your issue without the need for a bbappend.
Just inject that line via distro or local.conf

Thank you, Michael.

I have `DEPENDS = "virtual/arm-oe-linux-gnueabi-compilerlibs"`

and `do_compile[depends] += "virtual/arm-oe-linux-gnueabi-compilerlibs:do_check"`

However, libquadmath.so is still not present in `recipe-sysroot/lib`

I used the `do_check` task from gcc_runtime but that still isn't providing `libquadmath.so` in my $STAGING_LIBDIR, which is where I need it.

Many thanks.
