[ptxdist] Fortran with OSELAS

[-- Attachment #1.1: Type: text/plain, Size: 535 bytes --]

Hello

We are using OSELAS.Toolchain-2013.12.2 for an arm-v5te-linux-gnueabi architecture. Usually we are programming in C/C++. For an extra library written in Fortran-90 we need to cross-compile it. Since GCC is including fortran compiler, I am interested in how to configure the OSELAS.Toolchain to get the fortran cross compiler. I have seen in ./rules/cross-gcc.in that there is an option to activate it but I don't know how to proceed to get this menu and what is necessary after the activation.

Thanks for help.

You're following the documentation[1]  to build the toolchain, right?
After selecting the toolchain you want to build ('ptxdist select ...') you
can run 'ptxdist menuconfig' and select fortran in the gcc submenu, save
the config and then continue as documented.
Please note, that this might not work. This option has not been tested in a
very long time.
