rda build on x86_64

rda build on x86_64

[Ralf Wildenhues]

Hello,

I'm trying to build the full src tree, plain
  ../src/configure
  make

on x86_64-pc-linux-gnu (on my way of updating autotools in src).

The build fails like this:

| make[5]: Entering directory `/tmp/build/x86_64-unknown-linux-gnu/rda/unix'
| if gcc -L/tmp/build/./ld    -DHAVE_CONFIG_H -I. -I../../../../src/rda/unix -I. -I../../../../src/rda/unix -I../../../../src/rda/unix/../include    -Wall -g -O2 -MT linux-target.o -MD -MP -MF ".deps/linux-target.Tpo" -c -o linux-target.o ../../../../src/rda/unix/linux-target.c; \
|         then mv -f ".deps/linux-target.Tpo" ".deps/linux-target.Po"; else rm -f ".deps/linux-target.Tpo"; exit 1; fi
| In file included from ../../../../src/rda/unix/linux-target.c:50:

| ../../../../src/rda/unix/linux-target.c:1643: error: ‘NUM_REGS’ undeclared (first use in this function)

Looking at configure.in, x86_64 seems simply not supported.  Is a port
to the new x86_64 architecture planned?

Until then, would it be desirable to let toplevel not configure the rda
directory on x86_64 to avoid this build error (so the user doesn't have
to --disable-rda manually)?

Thanks, and please Cc: me on replies,
Ralf

Hello Michael, Hui,

first off, my previous mail-Cc to msnyder at redhat.com bounced
<http://thread.gmane.org/gmane.comp.gdb.patches/51142>;
time to update the entry in rda/MAINTAINERS (which is where I got the
email address from)?

Thanks; however, that is

- neither convenient for users not knowing they need a special option to
  disable rda,

- not an option for me when I want to update autotools inside rda or sid.
  I *need* a way to be able to build *all* parts of the tree (ideally
  as many as possible together in as few build trees as possible), in
  order to be able to test changes to the build system.

If you tell me the latter is simply not possible on x86_64, then I can
go to i686-pc-linux-gnu; that seems to work.

Cheers,
Ralf

FWIW I think most people working on gdb just don't check out rda.
You have to ask for it explicitly, it isn't in any of the other modules
from what I can see.

I think it would be reasonable to make the change you suggest, but only
if you are really motivated to do so.
