[Dev-C++] Few questions....

[Asfe e <e_...@ho...>]

Hi All,

Few questions...

1.What is the difference between Windows application,
   WinMain project, empty project and console application on the Devcpp ?
    Are these equal to the ones on MS VS6 ?
    Please explain briefly about each one.

2.Does Devcpp support MFC or just win32api ?

3.Where can I get the full documation for the Devcpp ? The help that comes 
with the app itself is
   partial.

I’m using Devcpp ver4 on Win2k.

Thanx,

Seth.

[Dev-C++] Strange message returned

[<ser...@ju...>]

No, I did not. However, I did re-associate them when I re-installed Dev-C++ 4.0

Thanks for replying. I thought noone was going to bother to help.

--------------------------------------------------------------
Did you unassociate the name selections for Dev-Cpp 4 when you uninstalled?

I couldn't reproduce your problem. If possible, please send me your project

4.9.8.4 and 4.9.8.5 versions are just updates, they do not change your 
compiler tree nor contains new include files. Or maybe i didn't get your 
problem.
If you use the Mingw compiler distributed with version 4.9.8.0 then you g++ 
include file path is include/c++.

[Dev-C++] Docs for Preprocessor?

[P.T. W. M. <pt...@ea...>]

Where can I find the documentation for the preprocessor?

Also, while I have installed the GNU C Library Ref in the Package Manager, 
I'm not sure how to gain access to it and use it.  As you can see, I'm a 
total beginner, even after reading the FAQ, and looking at the Docs on the 
Dev-C++ site.

Thanks,

Re: [Dev-C++] enum problem???

[jo m. <non...@ho...>]

Hello
I think I've found the problem: One of your Choices' enums is a macro. I've 
found DELETE defined at winnt.h. I don't know what it is used for, or how it 
is included, but if you delete DELETE, or rename it,  your program compiles.

[Dev-C++] Re: Config lost on Win2000 logoff

[Kevin B. <kev...@ma...>]

>After relocating the config files to their proper location on the network,

Oops, I spoke too soon. After a complete purging of the local profile cache 
and a new login, Dev-Cpp is still attempting to look locally for the 
Application Data instead of respecting the redirection. So, I have to 
manually transer my settings from the network to the local folder Dev-Cpp 
wants.

Thanks,

I finally found them. They are being stored in a local cache of my network 
settings, which is not replicated to the network on logoff. Apparently, 
they're supposed to be stored in the Application Data folder, but the 
"wrong" folder is being selected.

I think the issue here is that I am set up by a policy for Redirection. My 
profile's Application Data (among other things) is not stored locally at 
all, but is actually stored full time on the network. The Dev-Cpp config 
isn't being sent there; instead, it is going to a local directory under 
C:\Documents and Settings. Since the assumption is that things like that 
*should* be stored on the network, the logoff process does not upload 
locally stored Application Data to the network, hence the settings are lost 
every time.

After relocating the config files to their proper location on the network, 
indeed, problem solved.

So, anyway, I'm guessing this is a thing only when the Application Data 
folder is redirected to the network.

Thanks,

--- Kevin

[Dev-C++] Dependency Generation

[Kevin B. <kev...@ma...>]

I've noticed that when I have the "Use fast but imperfect dependency 
generation" option turned off, compiles fail with a "no rule to make 
target" error. "Build All" succeeds, but "Compile" fails with this error. 
Turning the "fast but imperfect" option back on eliminates the problem.

On my install of Win2000, which is set up for a network login, whenever I 
log off all the global configuration settings for Dev-Cpp are lost, and the 
next time I log in and start Dev-Cpp, it is as if I am running for the

Where are those settings stored, so I can make sure they get saved with my

[Dev-C++] Code Completion and cache

[Glenn W. <gl...@mr...>]

Ok, so this is the third post on this topic, but I'm just trying to =
understand how the cache works.
=20
In 4.9.8.4 the include directory has a c++ subdirectory which was =
scanned and included in the cache, but even including a file like =
iostream does not enable code completion but I'm not sure how this is =
supposed to work considering there are two files, one named iostream.h =
and one without the extension in two different directories. They even =
seem to be different files.  I can't tell whether the one listed in =
c++\backward is actually included because the window doesn't scroll =
horizontally.
=20
In 4.9.8.5 the include directory has a g++-3 subdirectory. By default =
this wasn't scanned and had to be manually added to the cache. Is this =
normal?
=20
Just trying to learn c++ and the code completion will go a long way =
towards familiarizing myself with the member functions but it seems to =
work differently on each system and I am not sure how it is supposed to =
work.

RE: [Dev-C++] 'string' was not declared in this scope

[P.D. v. Z. <pa...@my...>]

Everything from the standard C++ library should be (and in GCC it is) in the
standard namespace ("std"). You need to either import string into the
current namespace, or qualify the name explicitly.
In other words, either use:

using std::string;

or replace all your string variables from "string" to "std::string".
And while you're at it, read up on the C++ standard (especially namespaces)
:)

Regards,


Paul

[Dev-C++] Testing application.

[Asfe e <e_...@ho...>]

Hi All,

In order to do some testing, I’m trying to build a small tool that will 
allow
me to perform the next things:

Fill a web page text fields, radio buttons and click on buttons.
Read text from text fields (web and windows)

The ideal way will be to do everything with C++(win32api and native).
Maybe one of you can guide me to the right direction.
I'm using the devcpp ver 4.


Thanks in advance,

Seth.

[Dev-C++] enum problem???

[Opacki, J. <Jos...@ng...>]

Hello All,

I'm experience an error that I am completely unfamiliar with.  If someone
can help me, please do so.  I've listed the error lines and the compile log
directly below...and for the really brave, I've placed the whole program at
the bottom.

Line 19:	enum Choices { TEXTFILE = 1, UPDATE, NEW, DELETE, END };
*
*
Line 41: 	while ( ( choice = enterChoice() ) != END )

[Dev-C++] A question about overloading

[Maya <Esc...@ne...>]

In the parent class
~~~~~~~~~~~~~~~~~~~
class Parent{
public:
    int a, b, c, d, e;
    .....
    template<class charT, class Traits>
    friend std::basic_istream<charT, Traits>&
    operator>> (std::basic_istream<charT, Traits>&, Parent&);

    template<class charT, class Traits>
    friend std::basic_ostream<charT, Traits>&
    operator<< (std::basic_ostream<charT, Traits>&, Parent& );
In the chile class
~~~~~~~~~~~~~~~~~~
class Chile : virtual public Parent{
public:
    int f,g;
    ......
    template<class charT, class Traits>
    friend std::basic_istream<charT, Traits>&
    operator>> (std::basic_istream<charT, Traits>&,Chile&);

    template<class charT, class Traits>
    friend std::basic_ostream<charT, Traits>&
    operator<< (std::basic_ostream<charT, Traits>&, Chile& );

As you can see, the derived class also has a inserter and an extractor 
overloaded operator. However, in the driver program [main.cpp] I want to 
make a call to the overloaded inserter and extractor from the Parent 
class, but don't know how to go about it!
void main(){
    Chile obj;
    obj.a = 1; obj.b = 2; obj.c = 3;  obj.d = 4; obj.e = 5;    obj.f = 6;
    obj.g = 7;
    ...
    std::cout << obj << std::endl; // which inserter is called here?
}

Well, from a shell console (cmd.exe) type

[path_to_bin_dir]ar crs [path_to_lib_dir]libxxx.a [list_of_object_files]

where xxx is the name you would give to your library (the .a file) and
paths are subdirectories (bin, lib) in your compiler installation directory.
Then you can include object files in your project by writing in the 'link'
section of project settings the line

-lxxx

Note that you can even chose to keep the lib in your project dir, but you
should set in the options '-L.', that tell the compiler to search
libraries in your dir. Well, actually I'm not so sure about this.

If you need it, I can post you some man pages in ASCII format about 'ar'
or other tools.

Please, you all let me know if I said something wrong or stupid. Bye.

[Dev-C++] creating library *.a files with Dev C++

[Coosa <co...@gm...>]

Hi all,

I have the following problem:

I'm working with Dev C++ 4.9.8.5 and suppose i have the following =
scenario:
A project consistes of the following files:
  1.. project.dev=20
  2.. main.cpp=20
  3.. FileA.cpp=20
  4.. FileA.h
After compilation i get also:
  1.. main.o=20
  2.. FileA.o
Now later i can also delete the FileA.cpp and insted use the object file =
and just include the FileA.h to the project.
Theat's all fine.

But when i want to use the same file with a normal source file (not a =
project) i can't simply use the functions i created in the FileA.cpp and =
just include the FileA.h though i copied the FileA.o to the default =
library directory and the FileA.h to the default include Directory.

I heard later that i must create a FileA.a from the FileA.o, but i have =
no idea how to do this!
Can some please one help me on that?

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

Unix doesn't forbid the use of space in directory or file names. They are
just a slight nuisance, since you have to either put the names within
citation marks, or put a break character (\) before the space.

RE: [Dev-C++] Compile problems DevC++ 4.9.8.5

[P.D. v. Z. <pa...@my...>]

Hi,

You probably installed Dev-C++ in something like "C:\Program Files\...",
right? Always avoid any paths or filenames containing spaces when dealing
with tools originating in Unix/Linux... they don't handle spaces well
(considering they're invalid in Unix/Linux). Dev-C++ uses the MingW port of
the GCC compiler set as the compiler, which was originally written for
Unix/Linux. Completely uninstall (and delete the config files), and then
perform a fresh install. Install in a path _without any spaces_. Also, don't
place any of your source files or projects in paths with spaces (note: "My
Documents" and the desktop are paths with spaces as well!).

For more information, please look at this thread from the Dev-C++ forum:
https://sourceforge.net/forum/forum.php?thread_id=959971&forum_id=48211

Regards,


Paul

I have been using DevC++ V4 very successfully for the last year. Today I
upgraded to version 4.9.8.5 from http://bloodshed.net/dev/devcpp4985.zip 

I opened an old project, and tried to compile it and got this message: 
___________________________ 
Compiler: Default compiler 
Building Makefile: "C:\Users\CSroka\FreqPlan\Makefile.win" 
Executing  make clean 
rm -f main.o FreqPlan_private.res FreqPlan.exe process_begin:
CreateProcess((null), rm -f main.o FreqPlan_private.res FreqPlan.exe, ...)
failed.

make (e=2): The system cannot find the file specified. make.exe: *** [clean]
Error 2 Execution terminated 
___________________________ 

The files "C:\Users\CSroka\FreqPlan\Makefile.win" and FreqPlan_private.res
do exist in the project directory. 

So I thought the program paths are wrong and need to be set correctly. 

When I try to point to my DevC++ program folder (In: Tools->Compiler
options->Programs) I notice that all the paths are to C:\Program. Even if I
change them to my actual DevC++ program folder they always revert to
C:\Program. Could this be causing the problem? If so then how do I get the
programs to point to my actual DevC++ folder, and not C:\Program? 

Thanks 
Chris
