Description
cannot enable gfortran in core-image-full-cmdline

Steps to reproduce the issue:
1.
~/riscv-yocto/meta-rvcore/recipes-devtools/gcc$ cat gcc-runtime_%.bbappend
#FILESEXTRAPATHS:prepend := "${THISDIR}/${PN}:"
RUNTIMETARGET += "libgfortran"

~/riscv-yocto/build$ cat conf/local.conf
#enable fortran
FORTRAN_forcevariable = ",fortran"
#FORTRAN = ",fortran"

Describe the results you received:

| checking whether we are using the GNU Fortran compiler... (cached) no

Can you try

FORTRAN:forcevariable = ",fortran"

this message disappeared:
libgfortran was skipped: libgfortran needs fortran support to be enabled in the compiler

but has configure error, can you explain the principle behind this?
i am bitbake gcc-runtime or libgfortran, why it check "whether the GNU Fortran compiler is working" ?
i want to compile fortran compiler

kraj commented

@zhangze0722 fortran support comes from a separate recipe called libgfortran, Please try setting

FORTRAN:forcevariable = ",fortran"

in local.conf and try building again.

thanks a lot, I found that if no gcc-runtime_%.bbappend, gfortran will be ok.
