How to enable libgfortran in yocto scarthgap (stm32mpu157f-dk2)

[AbhijithKannan]

 

I want to enable libgfortran on OpenSTLinux distribution package. Based on the information that i found on the internet I added the following lines to the local.conf

 

IMAGE_FEATURES += "tools-sdk"
FORTRAN = ",fortran"
FORTRAN_forcevariable = ",fortran"
RUNTIMETARGET += " libquadmath libgfortran"
IMAGE_INSTALL += " gfortran gfortran-symlinks libgfortran libgfortran-dev"

But i am getting the following error

bitbake st-image-weston

Your error message indicates that libgfortran was skipped because "Fortran support needs to be enabled in the compiler." This suggests that the GCC toolchain used by OpenSTLinux is missing Fortran support.

Check if gcc-fortran is available:

 

bitbake -s | grep gcc

 

If gcc-fortran is not listed, you need to include it in your toolchain.

gcc-fortran isn't listed here. Could let me know to include it ? I am new to building images using yocto.
