[Botan-devel] Help with QNX/Momentics build

[Pat McHenry]

Regarding exit, it's declared in stdlib.h - which apparently just didn't get
pulled in anywhere for unix_cmd.cpp under the _QNX_SOURCE setup.  I just
included stdlib.h directly (and made the other two fixes you mentioned) and
the build is now error-free.

Thanks for your help.

I think the _QNX_SOURCE define was already supposed to be there for
you, it may have gotten lost when I partially rewrote the configure
script. Fortunately it's much easier to add it back now that that code
isn't a (total) mess.

Bug. I just looked, it's there, it's not supposed to be (I must have
been trying to track something down, certainly something that drastic
is not a good way of handling a simple error). You should remove the
call entirely.

Where is exit() declared on QNX? It's in (or at least made available
by) unistd.h on most platforms/standards I'm aware
of/encountered. That is a strange one.

Bug again, just forgot to include <iterator> there (GCC is too
forgiving (or alternately GCC drags too much stuff in when you include
standard headers)).

I'm afraid I don't have much. I occasionally do builds on QNX running
in VMware, but that really is the extent of it for me.
