Tested for qemuarm64 with multilib enabled:
1. set machine and enable multilib
require conf/multilib.conf
MULTILIBS = "multilib:lib32"
MACHINE = "qemuarm64"
DEFAULTTUNE:virtclass-multilib-lib32 = "armv7vethf-neon"
2. enable fortran and install to image
FORTRAN:forcevariable = ",fortran"
IMAGE_INSTALL:append = " gfortran lib32-gfortran"
3. build image and boot, run gfortran with option '-v' to verify
math-vector-fortran.h has been pre-included
for aarch64:
/usr/libexec/gcc/aarch64-poky-linux/14.1.0/f951 hello.f95 -quiet
-dumpdir a- -dumpbase hello.f95 -dumpbase-ext .f95 -mlittle-endian
-mabi=lp64 -version -fintrinsic-modules-path
/usr/lib/gcc/aarch64-poky-linux/14.1.0/finclude
-fpre-include=/usr/lib/gcc/aarch64-poky-linux/14.1.0/finclude/math-vector-fortran.h
-o /tmp/ccuPIzQY.s
for arm:
/usr/libexec/gcc/arm-pokymllib32-linux-gnueabi/14.1.0/f951 hello.f95
-quiet -dumpdir a- -dumpbase hello.f95 -dumpbase-ext .f95
