C++ library in QNXRTP

Hi,

I need help to use a C++ library in QNX. The library I have is NURBS++. (A
Nurbs library which ic compatible with linux,unix and even windows! and
available via http://yukon.genie.uottawa.ca/~lavoie/software/nurbs/). gcc
2.95 in linux works fine with with the library but I couldn’t manage to
compile it in QNX.

Can anyone help?

Thanks for your time.

You have posted in QNX4 conference and in a QNX6 conference. Which
OS are you trying to compile on, both?

I gave a try at compiling it under QNX6. It seems the following statement
cause
a problem.

#include
typedef ostrstream ErrorStream;

Since ostrstream is a class, when declared as such the error disappear
typedef class ostrstream ErrorStream;

I don’t know why it works under other OS. I have look for other type
of compile error either.

Mario:

What does this NURBS library do?

I don’t really know Dean, I was just trying to give a hand to Mr “please
help” :slight_smile:
From the documentation : "Non-Uniform Rational B-Splines (NURBS) curves and
surface are parametric functions which can represent any type of curves or
surfaces. This C++ library hides the basic mathematics of NURBS. This allows
the user to focus on the more challenging parts of their projects.

First of all sorry for cross posting and not being specific enough. I just
wanted to get an answer as soon as possible.
I appriciate any help.

Let me redefine the problem. I have QNX 6.0 and need to compile the
NURBS++

6.0? Ok then that’s different because the C and C++ library/header are
different
then with 6.1. I was using 6.1. I don’t have access to a 6.0 machine at
this
time to help you out sorry.

and
presumably platform independent, this library always needs some work to

270 is an unactive newsgroup which has may tips/tricks to compile it under
different platforms. I manage to compile it under linux and windows
myself,
but being a newbee not under QNX. I use gcc 2.95 compiler with QNX6.0.

By the way, for those who are interested in, the NURBS++ library helps you
to mathematically create your own surfaces (or curves), so that you can
create your own graphics. You can save results as VRML97 or .ps and even
view them with some GNU viewers. Many commertial complex CAD/CAM software
use a NURBS library, and this one is a free and a very powerful one.

Hi,
Maybe you can still explain me how you can run the configure without
problems. I guess you try to install the library as it is defined in
http://yukon.genie.uottawa.ca/~lavoie/software/nurbs/download.shtml. I am
not able to define a legal host type and default (guess) option doen’t work.

By the way I just learned that my QNX is Nuetrino 6.0. (if it makes any
difference.)

Thanks a lot.

The above won’t compile with the new ISO-compliant Dinkumware libraries which
make proper use of the std namespace.
You need either (preferably):

#include
typedef std::ostrstream ErrorStream;

or
#include
using namespace std; // you may need this in every header!
typedef ostrstream ErrorStream;


Note that strstream is deprecated, so you should instead use sstream in new
code (although there are things strstream can do that sstream can’t, so I
don’t think it should be deprecated).

You may be able to configure gcc to use the old libraries rather than
Dinkumware (check QDN?), and this may be the easiest solution for now.

Hi,

I repost my problem since I haven’t recieved any further response. This time
I try to be more clear. You are my only hope :slight_smile:)

I still need help to compile the Nurbs++ libray in QNX Neutrino 6.0. (The
NURBS library is available via http://telin.rug.ac.be/pub/ftp/sid/Nurbs/,
version 3.0.10)

I believe the problem occurs during linking with gcc 2.95.2. Here is what I
do:

tar -zxvf nurbs+±3.0.10.tar.gz
cd nurbs+±3.0.10
mkdir x86-pc-nto-qnx

(I add new config.sub and config.guess from ftp.gnu.org pub/gnu/config)

cd x86-pc-nto-qnx
…/configure

Everthing seems to work fine till here. Then

gcc --version

2.95.2

make: *** [all-recursive] Error 1



I believe the problem is due to gcc using wrong (old or maybe new)
libraries. The NURBS library is said to be ISO compilant and it works under
Linux with gcc 2.95.1
(http://yukon.genie.uottawa.ca/~lavoie/software/nurbs/download.shtml). I
have it working under VC6.0.

Please please please, help me…

Thanks.

Sorry, I know longer have a 6.0 machine, but this seems simple
enough. The error message is clear. All you have to do is
edit …/…/matrix/cvector.hh and put

#undef index

somewhere at the beginning.

index() was a macro in the old <strings.h>
#define index(s,c) (strchr(s,c))

Good luck.

I thought some one in this thread said, it compiled … no? was it
on 6.1?

There is something so … hmmm…

I decided to see what the fuss is all about, I salvage an old
6.0 that was not blown away, yet:

gzip -dc nurbs+±3.0.10.tar.gz |tar xvf -

cd nurbs+±3.0.10

cd matrix

vi cvector.hh

// edit the file and put
// #undef index
// after the #include
// save

cd …

// I was to lazy to get config.sub and config.guess from
// ftp.gnu.org pub/gnu/config)

CXXFLAGS="" ./configure --host=i386-svr4

make

…
ranlib .libs/libnurbsd.a
creating libnurbsd.la
(cd .libs && rm -f libnurbsd.la && ln -s …/libnurbsd.la libnurbsd.la)
make[1]: Leaving directory /home/alain/nurbs++-3.0.10/nurbs' make[1]: Entering directory /home/alain/nurbs+±3.0.10’
make[1]: Nothing to be done for all-am'. make[1]: Leaving directory /home/alain/nurbs+±3.0.10’

Voila!!

To recap:

  • Do not use Optimisation, some of the files will ICE gcc. If you
    do use -O2, you may have to compile some of the files by hand.
  • If you need debug, compile with -gstabs, ‘-g’ dwarf by default
    will ICE gcc when compiling matrix/vector.cc.

Best of luck,

Why would you suspect libraries? You’re only at the compile stage, not the
link stage… If you look in /usr/include/strings.h, you’ll find a macro
index(s,c) which takes two arguments. This is a case of a name collision so
you’ll have to either not include strings.h, do something like “#undef
index” or rename the index function in the Nurbs library.

cheers,

Kris

version 3.0.10)

I believe the problem occurs during linking with gcc 2.95.2. Here is what I
do:

tar -zxvf nurbs+±3.0.10.tar.gz
cd nurbs+±3.0.10
mkdir x86-pc-nto-qnx

(I add new config.sub and config.guess from ftp.gnu.org pub/gnu/config)

cd x86-pc-nto-qnx
…/configure

Everthing seems to work fine till here. Then

gcc --version

2.95.2

make

One of the main causes of the fall of the Roman Empire was that, lacking zero,
they had no way to indicate sucessful termination of their C programs.

Yep, it works… You are my HERO!!! :slight_smile:)) (I mean it.)

Thanks a lot, to you Alain and all others who tried to help. This is a great
newsgroup.

Thanks again. This will make a difference in my research.
