I have to investigate...

Do i have to use 2013.12.2 for ptxdist-2017.05.0?
Is there a download for Ubuntu 16.04 (64-bit)?

What about installing this lib?

This toolchain is quite old already. Anyway, the symbolic link
selected_toolchain in your BSP subfolder platform-dev should guide you
where the toolchain is on your local system.

No, you probably want a newer toolchain like
OSELAS.Toolchain-2016.06.1 for example.

I'm not sure, I did build those toolchains by myself from Git. O:-)

But if you feed your search engine with "oselas toolchain" you may
find some precompiled ones.

I tried the debugger from the toolchain.
But it dies, because it cannot find libncurses.so.5.

It is OSELAS.Toolchain-2013.12.2. I don't know where
it comes from (inherited, not self compiled).

I have to investigate...

Do i have to use 2013.12.2 for ptxdist-2017.05.0?
Is there a download for Ubuntu 16.04 (64-bit)?

Thanks

Hmm, gdb searches for ".debug" subfolders by its own. And 
the "./platform-dev/root" has these subfolders when the folder contains 
code files.

Did you try the gdb coming with your toolchain? You can easily access
it from your BSP, e.g.:

  ./platform-foo/selected_toolchain/arm-v5te-linux-gnueabi-gdb

> I do a "set sysroot .../ptxdist/platform-dev/root".

Do you have ./platform-dev/root-debug as a folder? Probably not, that
was dropped in an older version of ptxdist IIRC. Then you may have to
set symbol-file like this:

  symbol-file /home/adahl/…/platform-foo/root/usr/bin/.debug/.bar.dbg

(Adapt path, the file part should match with the binary you want to
debug.)

You should use the gdb from the toolchain, *not* the one from your 
host-system.
