[ptxdist] Failed to compile gdbserver

[Denis OSTERLAND]

Hi,

I try to compile gdbserver with OSELAS.Toolchain-2018.02.0 on armv5te + armv7a, but it fails.
I tried the default version 7.6.1:

You need to use the same version as the gdb in the toolchain. That's 8.1,
if I remember correctly.

Correct, that works.
Sorry, I mixed 7.8.1 and 8.1 somehow...

Just hit me too, same setup.
Well, with ptxdist-2018.09, but same topic.

Correct, there gdb 8.1 is used. Build is successful with
PTXCONF_GDB_VERSION="8.1"
PTXCONF_GDB_MD5="0c85ecbb43569ec43b1c9230622e84ab"


Might be worth to check this, like it's done with gcc and glibc.
Their versions are set in platformconfig (and checked), in this case:
PTXCONF_CROSSCHAIN_CHECK="7.3.1"
PTXCONF_GLIBC_VERSION="2.27"
And so kind of centralizing toolchain version dependencies.

But gdb version (which gdbserver follows) is set in ptxconfig, as
PTXCONF_GDB_VERSION and PTXCONF_GDB_MD5. Where it belongs to, as those
are installed to the target. Either gdbserver or even full gdb.

Thinking of ways to improve this, I could imagine

1.) keep PTXCONF_GDB_* in ptxconfig, but add some "use version from
toolchain" config flag, which will in turn take the data setup in
platformconfig (probably new options there)

2.) add it somehow to "ptxdist migrate" (sensible / doable ?)

3.) at least add a comment to the config options

For #3 I could send in a patch, for #1 or #2 I'd need some assistance
from PTX side.

Michael, what do you think, and prefer ?

Best regards,
  Andreas

I've implemented something like this:
For an OSELAS.Toolchain it will now fetch the version and md5 from the
toolchain ptxconfig. The md5 can be overwritten if necessary.
For all other toolchains <prefix>-gdb --version is parsed and the md5 must
be specified.
This is all optional, the old way to specify version and md5 can be used
too.
