libgfortran.spec not found

[Tomas Veiga]

Hello,

I'm trying to build the gcc toolchain with Yocto.

I'm currently building it with `bitbake meta-toolchain -c populate_sdk` 
and then running the installer 
`tmp/deploy/sdk/poky-glibc-x86_64-core-image-sato-core2-64-toolchain-ext-5.2.999.sh`.

gcc and g++ work fine, but gfortran doesn't, getting the error:
`x86_64-poky-linux-gfortran: fatal error: cannot read spec file 
‘libgfortran.spec’: No such file or directory
compilation terminated.`

I've tried copying the `libgfortran.spec` file from 
`./build/tmp/sysroots-components/core2-64/libgfortran/usr/lib/libgfortran.spec` 
to 
`sysroots/x86_64-pokysdk-linux/usr/lib/x86_64-poky-linux/gcc/x86_64-poky-linux/14.2.0/libgfortran.spec` 
but then I get several `no such file or directory` errors for Scrt1.o, 
crti.o, crtbegins.o, etc....

I've also tried these suggestions but made no difference.

Hoping anyone has got any insight?
