RE: [linuxsh-shmedia-dev] How to build Barcelona-20030310

[Andrew S. <and...@su...>]

Why do you want to rebuild barcelona? Did you not download the binaries?
I suppose there may be many reasons for this.

The target we use for all the tools is sh64-superh-linux-gnu. I haven't
tested sh64-linux so I can't say that it works. Just 'sh' is definitely
wrong as that would be SH1-4, but not 5.

gcc is configured with --target=3D... --prefix=3D... --with-headers=3D...
--with-libs=3D... --enable-languages=3D... --without-newlib --disable-sha=
red
--disable-multilib --disable-nls

The binary barcelona gcc will actually tell you what it was configured
with if you use the -v option.

The --with-headers and --with-libs should point at an installation of
glibc. These are always required for a cross compiler (for the target
libraries), but if you do not have this then you can omit them and NOT
build c++. Then when you have a C cross compiler use that to build glibc
and then rebuild the compiler with the c++ afterwards. The c++ doesn't
work very well anyway.

I'll assume you know how to build glibc till you say otherwise.
