[yocto] Adding Fortran to Raspberrypi2

[Edward Vidal]

Hi

Trying to add fortran to 6.2.0 branch morty for a Raspberrypi2

Step 1 modified meta/recipes-devtools/gcc/gcc-6.2.inc
-FORTRAN = ""
+FORTRAN = ",fortran"
bitbake core-image-sato created the image 

Testing on target. I see fortran in the command gcc -v.

gcc -v --enable-languages=c,c++,fortran gcc version 6.2.0 (GCC)

With the command ./configure for octave.
checking whether a usable Fortran compiler was found... no
configure: error: A Fortran compiler is required


Step 2 Checking the mailing list.

    |Fortran support in gcc is disabled by default, to enable it add the following line to your config, then build the libgfortran package.

    |FORTRAN_forcevariable = ",fortran"

I added FORTRAN_forcevariable = ",fortran" to my config.  Still no fortran.

I added libgfortran to variable IMAGE_INSTALL_append and I get the following error
 
ERROR: oe_runmake failed

../../../../../../../../work-shared/gcc-6.2.0-r0/gcc-6.2.0/libgfortran/runtime/backtrace.c:37:33: fatal error: backtrace-supported.h: No such file or directory
 #include "backtrace-supported.h"
                                 ^
compilation terminated.

Thanks in advance,
