C++ cross compiler issues

[mkirby]

Hi all,

Just getting back in to my SGI's now i have room to have them running again. I have hit a bit of a snag getting a C++ cross compiler working and im hoping somoene can tell me where i have gone wrong.

The C compiler works and i have compiled quite a bit of working code that is now running merrily on my Octane.

Here's the output of trying to compile a hello world

compilation terminated.

Its obviously something to do with the missing directory but i dont have the brains to work out what i have done wrong.

any ideas?

Not sure how you cross compilation environment was setup, but this line

Configured with: /nfs/programming/ruby/cross/factory/src/gcc-9.2.0/configure ... --disable-libstdcxx ...

might give a clue

Thanks both.

I fixed the issue. In gcc-9.2.0/libstdc++-v3/configure comment out line 78630. This stops configure bailing and allows it to build the library. g++ now works correctly.
