Hallo,

Does anybody have experiences in using WATCOM compiler and STL (STLport.org) ?

I tried to compile a project, and recognized problems. I use wpp386 (V 10.6) STL
(V4.0).

Any hints apreciated?

I’m using an older version of stlport, haven’t bothered upgrading yet. It’s hard
to give hints without you giving some details on what you did…

What type of problems? I’m using the new version with no problems other
than being able to compile the SGI iostreams…

Watcom is pre ANSI, you’ll need to specify an allocator and namespaces
are not implimented.

main () {
stack<int, allocator> buffer;
}

I find that it’s good to use typedefs with Watcom, ie:
typedef stack<int, allocator> intStack;
typedef stack<int, allocator>::iterator intStackIt;

main () {
intStack buffer;
}

What may be the problem. Does this code work with your compiler ??

Jon will probably be able to give you more specific suggestions,
but Watcom supports neither namespaces nor default template parameters.
Since stack<> is an interface to some other container, it needs to
have that container type specified. It’s supposed to default to something,
but the defaulting uses a default template parameter, so no worky under
Watcom.

Hello,

Your stack example should work fine. The second paramater is supposed to
default to a deque. I haven’t used stack yet but taking a look at it there
is some define called “__STL_LIMITED_DEFAULT_TEMPLATES” that probably gets
set in one of the config.h files. I think I would just specify the second
argument myself intead of playing with all the configuration ifdefs in
Stlport. eg:

stack<int, deque > mystack;

The default is a deque, you can use whatever you want…

And the Watcom compiler doesn’t support namespaces so you don’t need (and
can’t) the usual using namespace std; which is a bit unfortunate. There is a
gcc port avail. for QNX but I haven’t used it too much. The gcc compiler
that comes with Neutrino is good though.

Let me know if you have any other questions.

aah yes, watcom doesn’t support default template params… so don’t play
around with the ifdef I mentioned below!

Somehow?

See http://www.sgi.com/Technology/STL/stack.html.

The stack is template <T, Sequence = deque>, but defaults aren’t
allowed so try putting the default in yourself.

typedef stack<int, deque> intStack;

You may find that deque<> needs a parameter that is usually specified
by a default template paramter, if so follow the docs to see what that
is.

I think the previous poster was typing too fast, there are places in the
STL where an allocator is specified by a default template parameter, and
this is probably one of the most requently asked questions, but
if you look at the docs for stack you’ll see that what is required is
a container. Read the docs for container adaptors, and for stack.

wpp386 -d3 -db -bt=QNX -hw -i=/prj/gmc/dvp/STLport-4.0/stlport -i=/usr/include
-i=…/inc test.cpp

Also, are you providing this command line yourself? I would recommend using
dwarf debugging format, watcom’s has some hardcoded limits that you’ll reach
quickly with C++ and the STL in particular, and always use the cc front end:

/tmp$ cc -g3d -c _.cc
/usr/watcom/10.6/bin/wpp386 -zq -d3 -hd -ms -4r -i=/usr/watcom/10.6/usr/include i=/usr/include _.cc

Hi,

thanks a lot for your help. Me and the compiler are fine with

typedef stack<int,deque > intStack;

Yes, I’ve not used stack before and just assumed that it was like
vector<> which does need the allocator…

Just to follow up on this discussion, if you set

__STL_MINIMUM_DEFAULT_TEMPLATE_PARAMS to 1 in stl_user_config.h

then you can indeed write

stack mystack; // Uses default deque

The downside of this is that now, if you DO want to override the default
then you have to use an alternate form like

stack<int, deque> mystack2;

The same applies to map<>, multimap<>, set<>, multiset<>, queue<> etc. This
is all documented in stl_user_config.h (probably in the docs too but I
didn’t look).
