[Dev-C++] Problem debugging in library with version 4.9.6.0

[Bill W. <bil...@at...>]

As a new user porting my source code from Borland 5.02 and Unix, I have =
run into a debugging issue.
I jhave created a library, and a calling program called MainProg.
I cannot seem to get the debugger to step into any of the source coce =
modules for the library. =20

The debugger seems to behave like it is entering the module, but nothing =
happens on the screen when you do 'Next Step'. =20
If you do a 'Step Over', you return properly to the next line in the =
calling source file.

Even if I add a given .cpp file from the library to the MainProg =
project, I cannot debug into it.  The debugger only seems to work  when =
stepping into functions that are in the MainProg .cpp file itself.

Both the library and the Main program have been linked with debugging =
turned on.

Does anyone have a clue as to what I may not have set properly, or is =
this a problem with the GDB degbugger in connectionm with the IDE?

Thanks in advance,

Bill

[Dev-C++] dllwrap problem w/ mingw gcc 3.1

[Vern-N <ve...@cs...>]

trying to compile the default DLL application using the MinGW 
3.1 compiler, libs, and includes... also have msys bin folder 
in my path after mingw.  this is the 2.0 snapshot of MinGW.

The generated makefile works fine from a cygwin window, but 
trying to compile w/ dev-c++ gives the following log:

Executing  make...
make.exe -f "C:\newdll\Makefile.win" all
g++.exe -c dllmain.cpp -o dllmain.o -I"C:/Program 
Files/MinGW/include"  -I"C:/Program Files/MinGW/include" -
I"C:/Program Files/MinGW/include/g++-v3"  -DBUILDING_DLL=3D1 -s
dllwrap.exe --output-def libnewdll.def --driver-name c++ --
implib libnewdll.a dllmain.o  -L"C:/Program Files/MinGW/lib" -
-no-export-all-symbols --add-stdcall-alias -o newdll.dll
c++: =A0=86: No such file or directory
c:\Program Files\MinGW\bin\dllwrap.exe: no export definition 
file provided.
Creating one, but that may not be what you want
c:\Program Files\MinGW\bin\dllwrap.exe: c++ exited with status 
1
make.exe: *** [newdll.dll] Error 1
Execution terminated

All I can figure is something is going wrong w/ the 
commandline for the dllwrap command...

Would really like the convenience of not having to compile 
from the cygwin shell.

I've searched the lists for this problem for some time, and 
have not come up w/ any similar problems...

Any help would be appreciated.
Please carbon-copy any responses to me, as I may not be 
monitoring the list directly.
Thanks,
-Vern

[Dev-C++] Apstring

[Gregory H. <gr...@fr...>]

I'm having trouble using apstring in Dev-C++. My code is:
#include "iostream.h"
#include "apstring.cpp"

int main ()
{
    apstring testString = "test";
    if (testString == "test"){
        cout << apstring
    }
}
I get 6 C:\Dev-Cpp\projects\irs\test.cpp `apstring' undeclared (first use
this function).
When I put apsting.cpp into the function, the first error is the ::.
Any suggestions?

Ok you have confused things. Forget the whole thing completely. Just do:

// Example
#define MY_TYPE int

CBase	*c =3D new CDerived;


If you want to point to it using some pointer of entirely foreign type,
this means you must know what you are doing and use a cast (in your case
the ugliest of all, reinterpret_cast).


MY_TYPE *f =3D reinterpret_cast<MY_TYPE *>(c);



Forget those operators you were using.

Read up un 'stat', 'lstat' for information about files and directories

make sure that you link with libc.

Then read the paragraph about 'scandir' if you use Unix or 
'FindFirstFile'/'FindNextFile' on Windows

int fl_filename_isdir(const char* n) {
   struct stat    s;

#ifdef WIN32
   char        fn[1024];
   int        length;
   // This workaround brought to you by the fine folks at Microsoft!
   // (read lots of sarcasm in that...)
   length = strlen(n);
   if (length < (int)(sizeof(fn) - 1)) {
     if (length < 4 && isalpha(n[0]) && n[1] == ':' &&
         (isdirsep(n[2]) || !n[2])) {
       // Always use D:/ for drive letters

       n = fn;

Re: [Dev-C++] List files and check if a directory exist.

[<we...@ha...>]

Hi Guys,

Thkz a lot Carlos.


>I haven't learned about it yet, but the solution is in >dirent.h, do a
search ...

Ok, i searched. But all examples that i found didn't compile.

See the example:

#include <stdio.h>
#include <dirent.h>

int main (){

DIR *dirh;

struct dirent *dirp;
static char mydir[20] = "/etc";

if ((dirh = opendir(mydir)) == NULL){

    perror("opendir");
    return(0);

}

for (dirp = readdir(dirh); dirp != NULL; dirp = readdir(dirh)){

    printf("Got dir entry: %s\n",dirp->d_name);

}

closedir(dirh);

}

When i compile i received this error:


[Linker error] undefined reference to `opendir'
[Linker error] undefined reference to `readdir'
[Linker error] undefined reference to `closedir'

What is wrong ?? How to solve it ??

Ahhh, the lib dirent.h appear that haven't a funciont to check if a
directory exist. Someone knwo other way to check ??

Thkz a lot.

Best Regards.

Re: [Dev-C++] DevCpp, Cygwin and DevPacks of GUI Toolkits

[Matthias <mm...@ma...>]

The Package Maker is a rewrite of the original code that is checked into 
  the Dev-C++ CVS at Sourceforge.

I published the source code to, so you guys can change/add to it. 
Remeber though, it is - like the original - under GPL license. That 
means that you have to publish all the changes you do.

It would be great if someone could add Makefiles for Linux and Dev-C++ 
and post them back to me. BTW: it should also compile on Mac OS... .

[Dev-C++] Package Maker utility

[Colin L. <col...@wa...>]

Hello,

We wrote a small package maker, which i was going to release soon.
As it was asked on the mailing list, you can download this utility at 
http://bloodshed.no-ip.org/dev/PackMaker.tar.gz
It should be a matter of minutes to create a .DevPak using it.

Greetings,

Hi,

I had a similar problem, in my case I changed the environmental =

[Dev-C++] Re: Dev-cpp-users digest, Vol 1 #1034 - 15 msgs

[Samuel K. <big...@ya...>]

okay,

I got another one for you. I thought windows would
create a file named LPT1 and put it in the directory
where I ran the .exe file. It didn't. I changed the
file name to USB1 and looked again. There was a file
named USB1 in the same directory as my .exe file. 
When I write LPT1 though and run the .exe file, I have
to stop the program by going through ctrl alt del.
Nothing is ever printed, no file made, or if it is I
don't know where it is going. I'm confused. Here is my
source if it will help.

#include <conio.c>



char PrintBuf[5000]; // make it large enough!

int printer(const char *Format,...) //user defined
function
{
char *Ptr = PrintBuf+lstrlen(PrintBuf);


va_list arglist;

va_start(arglist,Format);
vsprintf(Ptr,Format,arglist);
va_end(arglist);
return printf(Ptr);
}

int main()
{

FILE* sfile;
PrintBuf[0] = 0;


// your program runs here......
// just use printer() instead of printf. 
// It will print text to screen and into the buffer
// example:
printer("\t\t\tS K DATABASE SOLUTIONS\n\n");
printer("\t\t\t=-=-=-=-=-=-=-=-=-=-=-\n\n");
printer("Employee ID: %d\n",1001);
printer("Employee Name:%s\n","Shashi");
printer("Employee Pay:%f\n",1000.75);
printer("-===-=-=-=-=-=-=-=-=-=-=-=-");

// Now print the buffer to the printer

sfile = fopen("LPT1","wt");


if(sfile)
{
fwrite(PrintBuf,1,lstrlen(PrintBuf),sfile);
fputc('\f',sfile); // add a formfeed for pageprinters
fclose(sfile);
}

return 0;
}

Thanks Carlos,

You was right, declarations have to be at the front or
.c files. I'm used to writing in c++ and forgot about
that. Trouble is this only works for Linux because it
treats printers as files while windows (I think)
treats them differently. So I still can't print.

Re: Antw: [Dev-C++] DevCpp, Cygwin and DevPacks of GUI Toolkits

[<Ech...@ne...>]

A DevPak file is a *.tar.bz2 file with it's extension renamed to .DevPak

I don't believe there is any documentation on the format of the package,
but it is fairly easy to "reverse engineer".  I have made a DevPak 
(http://echempel.freezope.org/projects-fall2002/SigCpp-DevPak/libsigcpp-1.1.DevPak) 
in this manner.  I would suggest downloading a few existing DevPaks, 
renaming them to ____.tar.bz2, un-packing them, and then replacing the 
contents with your desired contents.  After this all that is needed is to 
repackage and rename the ___.tar.bz2 file to ___.DevPak.  

Hope this is helpful, if you need any more help feel free to contact me.

Absolutely. Sorry, I'm probably not being very clear :)
MY_TYPE *p = *c
Does work, problem is, what I'm looking for is some operator that does:
MY_TYPE *p = c;

I don't think this is possible...but you never know!

Style issues aside.

Correct me if I'm wrong but, your
  operator CDerived::MY_TYPE*();
converts from a CDerived object to a MY_TYPE*.

However, you try to use it to convert from a CDerived*.

This would work:
	MY_TYPE *p = *c;

RE: [Dev-C++] Why doesn't this compile?

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

Style issues aside.

Correct me if I'm wrong but, your
  operator CDerived::MY_TYPE*();
converts from a CDerived object to a MY_TYPE*.

However, you try to use it to convert from a CDerived*.

This would work:
	MY_TYPE *p = *c;

Nope, <stdio.h> does.

No, actually, if(fp) is right. This is basically

if(fp != NULL), which is what we're checking for. We're checking the
pointer, not the value of the structure (which could be anything, it's
totally unrelated to the pointer).

RE: [Dev-C++] Why doesn't this compile?

[Andrew V. <av...@in...>]

Ummm...MY_TYPE can be any type, change it to "float" if you like,
doesn't make any difference like I said.
I know the constructors etc... aren't strictly needed, they don't stop
it compiling or working though.
Also, the constructors etc... *are* required for the actual
implementation - this is just a stripped down and renamed version for
test perposes.

Oh, and I disagree with the "better to 'return 0'" comment :)
0 is an integer, I know NULL is just #defined as 0, but using NULL
implies a pointer type.
You wouldn't type the following:

UINT I = 27 + NULL;

Would you?, so why write:

UINT *p = 0;

?

You can ommit the above two.

Better: return 0;

Re: Antw: [Dev-C++] DevCpp, Cygwin and DevPacks of GUI Toolkits

"Frank Wagner" <F.W...@wi...> writes:

Hi,

A DevPac is a bzipped2 tar file with the addition of a "Manifest" file
in the root (of the archive) directory entitiled
"PackageName.DevPackage".

This file is very important and is an .ini file.

[Setup]
Version=1
AppName=LibXML
AppVersion=2.4.22
AppVerName=LibXML 2.4.22
MenuName=LibXML
Description=An XML parsing library.
Url=http://www.libxml.org/
Readme=Readme.txt
License=License.txt
Dependencies=i18n

[Icons]
Website=http://www.libxml.org/
Introduction=http://www.xmlsoft.org/intro.html
Documentation=http://www.xmlsoft.org/docs.html
FAQ=http://www.xmlsoft.org/FAQ.html

[Files]
include=<app>\include\
lib=<app>\lib\

Note that during the install, the include and lib files are copied
over and, for the above DevPack, the first directory layer looks like
this:

libxml-dev-2.4.22/:
LibXML.DevPackage  License.txt	Readme.txt  include/  lib/

So, after you make the directory structure, you can tar it up and then
run it through bzip2. Call it something with a DevPak extension.

tar cf - libxml-dev-2.4.22/ | bzip2 -c > libxml-dev-2.4.22.DevPak

[Dev-C++] Creation of devpacks - C++ port of dev-c++

[Christophe C. <chr...@fr...>]

Hi,

you should use dev-cpp package maker to create new devpacks.
I don't know of any exe distribution of this tool, but you can get it's
source from dev-cpp cvs.

If my memory is OK, borland offers a free personal delphi version to
download. I didn't find it anymore, but at least you can freely download
kylix.

But I think a C++ rewrite wouldn't be a so bad idea, since I'm not very
used to pascal...
It would be great to compile dev-c++ with "itself" (not really cause it
isn't the compiler, but...)
