Re: libquadmath

The following I just found in local.conf.sample.extended

# Enabling FORTRAN
# Note this is not officially supported and is just illustrated here to
# show an example of how it can be done
# You'll also need your fortran recipe to depend on libgfortran
FORTRAN:forcevariable = ",fortran"

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

I think to clarify...what I need are these files:
--- snipped from gcc-runtime.inc ---
```
FILES_libquadmath = "${libdir}/libquadmath*.so.*"
SUMMARY_libquadmath = "GNU quad-precision math library"
FILES_libquadmath-dev = "\
    ${libdir}/${TARGET_SYS}/${BINV}/include/quadmath* \
    ${libdir}/libquadmath*.so \
    ${libdir}/libquadmath.la <http://libquadmath.la> \

```

to be in my $STAGING_LIBDIR
So far, I have been unable to figure out how to do that, unfortunately.

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.

Not familiar with Fortran but maybe it helps to know that this
is normally handled with the DEPENDS mechanism. When you add
other recipes as dependencies to your recipe, the task
do_prepare_recipe_sysroot (run before do_compile) will make hard
links to the files from those dependency recipes into that
recipe-sysroot directory.
See:

Kind regards,

okay...I think I have a more interesting question now...
In the package I am building I have some Fortran code that
requires `libquadmath`
I see that `gcc-runtime` provides the library but I need the
library present in `recipe-sysroot/lib` when my `do_compile`
runs
Is there a way for me to do that?
My current approach is to build my image, copy the
libraries/includes to my recipe and `install` them in
`recipe-sysroot` before `do_compile`
This doesn't seem like the correct approach but I am not
sure how else to do it at this point
Any help would be greatly appreciated.
