[Dev-C++] Linker problems

[Lists <li...@dr...>]

Ok, forgive the ignorance.  I'm new to Dev-C++ and used to compiling the =
old fashion way, with an abacus.

Anyhow, I'm trying to compile a very basic OpenGL program (basically to =
just open a window with a GL RC).  Every time I do I get these errors:

-file format not recognized, treating as linker script
-parse error

I tried figuring out the problem with no luck.  I tried copying and =
pasting the linker paramaters diretcly from another working OGL project =
in Dev-C++, but still no dice.  Any ideas?

I mean that it needs __specific__ hardware. I don't think that gamers

3dfx Glide was not free, and so an alternative came (hardware supported 
OpenGL - I know this existed earlyly, but don't get into details

[Dev-C++] gsl installation or package??

[Ricardo R. <ri...@un...>]

I would like to know if there exists a package for automatically installing
the GSL (GNU Scientific Library) in  DEV-CPP.
In any case perhaps it would be a good idea to have the availability of
this possibility. The experts for the creation of packages for Dev-Cpp
could consider this question.

any help would be appreciated.

Re: [Dev-C++] OT - Why do I receive my messages twice?

[Per W. <pw...@ia...>]

When we answer mails from you - the default form is that we send the
answer to the list (one copy that you will get) and than we send a cc
directly to you.

There are a number of guys who doesn't subscribe to the list, so they
would not see any answers at all if we only sent to the list.

If we would not reply to all addresses, the answers would ONLY go to you,
and there would be no copy to the list.

Summary. For the majority of mail programs, we would have to do extra work
to first select 'Reply to all addresses', and then clear out the To field
and move the CC field to the To field.

[Dev-C++] including header file: <cstrstream>

[Luigi S. <gi...@li...>]

Hello all,

while answering to a message from the list, a question came to my mind.
Pre-ISO C++ compilers had the string stream class interface contained
in the header file: strstream.h, which, of course, is not part of the 
C library, so the following include directive:

#include <cstrstream>  

should be wrong, am I correct?

I could be wrong here, but: are you sure the compiler you use with Cygwin 
is *version 3.2* of Gcc?  Don't you get an error related to the header file
"strstream" when using Gcc 3.2 under Cygwin?

IMHO, You should, because the header "strstream" does not exist; generally,
one has:
 - pre-ISO C++ compilers:  "strstream.h"   or   "strstrea.h" (8-char issue)
 - ISO-C++: "sstream"

No changes is required to the source files, as these are processed by
the underlying compiler

AFAIK, you may set up any version of Dev-C++ to work with any version
of Gcc, because, basically, what Dev-C++ uses is the name of the compiler
(Gcc) and a few options, other stuff is under the control of the user.
In principle, you may hack Dev-C++ (without recompilation ;-) to use
other compilers too. 



> May I use gcc makefiles in DevC++ ?

The answer is both: no and yes :-)
 - no because there doesn't seem to be (yet) an utility that converts 
   makefiles into Dev-C++ project files 
 - yes because you probably have the program Make (which comes with
   Gcc) and so can use the makefiles directly to compile your program

Re: [Dev-C++] Access databases

[Yeoh H. <ye...@ye...>]

Hi Derick,

I'm glad to help. :-) And, you're right. I'm in the middle of a project
right now so I don't have much time. :-( But I can point you to a URL for
more information. Iczelion's Win32 Assembly Homepage has, IMHO, very good
ODBC tutorials. Although the code is in asm, his explanations on ODBC basic
programming approach, the API functions to call, the relevant function
parameter values, return values and in what order to call those API
functions are _very_ clearly explained.

Compared to MSDN, this is better and more concise. :-)

The five relevant topics covered are:
1. ODBC Basics
2. Connecting to Data Source
3. Preparing and Using Statements
4. Retrieving Results
5. An ODBC Example

The URL is:
http://win32asm.cjb.net/  in the Tutorials section.

For a tutorial in C using Visual C++, here's a URL I found sometime ago.
http://www.cxd3.com/tut/cpp/odbc/odbc.html

Many thanks to opcodevoid for providing this tutorial for free.

The C++ example program I wrote using Dev-C++ is based on his tutorial
example.

Yeoh

Re: [Dev-C++] Access databases

[Per W. <pw...@ia...>]

GlobalAlloc is like malloc() but it allocates memory directly from
Windows. It has a number of tricks, like placing the memory block in first
MB of memory etc.

GlobalLoc() tells Windows that it may not move or swap out the memory
block. This allows safe communication between multiple programs, or direct
memory access (DMA) transfers to/from hardware without the processor being
involved.

For a good reference to SQL functions, you might go to:
http://odbcrouter.com/api/SQLExecDirect.shtml
and look.

In which case, you are gettin gout of the GPL world and gettin ginto the
MS specific world of OLE / COM / ADO + other acronyms :-)

I figured as much. As I mentioned before there is a time constraint (about 2
weeks). I already have the database set up, so pulling reports, issuing
queries, input forms and basic transactions are already sorted. All I need
to do is write a small program to read from the serial port and write into
the database. The rest is already done. Rewriting the program with all the
functionallity it has now will take me more than 2 weeks - espescially if I
need to learn a few new libraries.

But you are locking yourself fairly tightly into a Windows / Access
world. There are zillions of database toolkits, classes, libraries etc.
If you need something simple, do you need Access? Can't you build a
simple database into your own program? Access doesn't come cheap. Why
not have that part of the profit for yourself where possible :-) Lets
face it, how many line items are you likely to need to store? A few
hundred?

This might be a sollution for version 2 of the program...When I am more
familliar with FLTK (or whatever makes gui easier) and gui development. This
is not something I can become good at overnight! I am very busy working
during the day and most of my free time is swallowed by my family. I have at
most 2 hours a day to do my studies (I am starting my degree this year- part
time), homework and programming. So when I say 2 weeks, I mean 4-8 hours if
I am lucky. Far too little time for a hobbyist programmer like myself to do
a full project!

But you are locking yourself fairly tightly into a Windows / Access
world. There are zillions of database toolkits, classes, libraries etc.
If you need something simple, do you need Access? Can't you build a
simple database into your own program? Access doesn't come cheap. Why
not have that part of the profit for yourself where possible :-) Lets
face it, how many line items are you likely to need to store? A few
hundred?

This might be a sollution for version 2 of the program...When I am more =
familliar with FLTK (or whatever makes gui easier) and gui development. =
This is not something I can become good at overnight! I am very busy =
working during the day and most of my free time is swallowed by my =
family. I have at most 2 hours a day to do my studies (I am starting my =
degree this year- part time), homework and programming. So when I say 2 =
weeks, I mean 4-8 hours if I am lucky. Far too little time for a =
hobbyist programmer like myself to do a full project!

Hello everyone,

Actually you can write a C++ program to access a Microsoft Access database
without requiring the user to setup the ODBC DSN. I've written an example
program using Dev-C++ 4.9.8.0 (GCC3.2) that reads from a Microsoft Access
2000 database that does not require the user to setup any ODBC DSN.

If you like I could e-mail the sample source code to you. :-)

Re: [Dev-C++] Pos and Pre Incremental/Decremental Operators Examples

[Per W. <pw...@ia...>]

Example 2 - you forget about the execution order of for statement.

for (i=3D0; i < 10; i++) cout << i;

is similar to

i =3D 0;
while (i < 10) {
  cout << i;
  i++;
}

so obviously, changing i++ to ++i doesn't change function. For a change,
insted test:

i =3D 0;
while (i++ < 10) {
  cou << i;
}

which becomse

for (i =3D 0; i++ < 10;) cout << i;

Now, i++ or ++i does matter.

[Dev-C++] Pos and Pre Incremental/Decremental Operators Examples

[<and...@su...>]

Dear Users:

Please consider the following examples:

Example 1:
...
int c;
c=0;
cout << c++; ---> it will print 0;
cout << c;   ---> it will print 1;
c=0;
cout << ++c; ---> it will print 1;
cout << c;   ---> it will print 1;
...

Example 2:
...
1-int i;
2-for(i=0; i<10; i++) cout << i; ---> it will print 0 to 9
3-for(i=0; i<10; ++i) cout << i; ---> it will print 0 to 9 (too!)

Statements/Questions:
1-I only have example #1 style to teach pos and pre incremental operators;
2-I thought in Example 2, line 3 an output like numbers 1 to 10. Why this
not happens?
3-Does anybody have good and simple examples of using pos and pre
incremental/decremental
  operators?

Regards
Andre

In which case, you are gettin gout of the GPL world and gettin ginto the

[Dev-C++] compilation problem

[<mar...@po...>]

Hi,

I am newbie in DevC++ and gcc so excuse me my question.
And sorry for my English.
I have got the C++ sources which I can compile successfully with gcc 3.2 at
Cygwin.
What changes should I make to these sources in order to compile them in
DevC++.

Does DevC++ 5.0 use gcc 3.2 ?
May I use gcc makefiles in DevC++ ?


Below, there is a fragment of code that causes compilation error -
strstream, strstreambuf,
istrstream and ostrstream - not declared.

[Dev-C++] openrt

[<or...@vp...>]

Hello!

Okay, some people are fascinated by Longhorn, I'm fascinated about 3D :)

Take a look at http://www.openrt.de

And yes, this has to do something with programming, as it is something 
like opengl, but with ray-tracing, and it may change peoples direction 
in 3D development...

Re: [Dev-C++] Access databases

[Per W. <pw...@ia...>]

When programming with M$ I have used DAO a lot. It doesn't need any ODBC
registration to work - it's the native method that Access uses to access
the it's databases. Alas, it is using Com, so if you don't find any sample
code it's probably too much work.
