[Dev-C++] debugging macros

[Marc H. <ma...@e-...>]

Hi All,

I'm having a little trouble debugging. What I'd like, is something like the
VC++ TRACE macros (and maybe TRACE0, TRACE1, ...) to write to stderr, and
then to be able to view that during execution. Unfortunately, although I've
been programming for a long long time, I've never had a need for these
goodies before, so I don't even know where to start. Perhaps someone could
give me a bit of a pointer in the right direction, or a web tutorial, or
something.

Thanks,

[Dev-C++] vUpdate bug?

[<cg...@wo...>]

I read 4.9.7.1 it's there yet, today I ran vUpdate for its purpose, and 
I find that there is a message sayin 4.9.7.1 is done, but it is not in 
the update section, as critical update, and there is the crash detection 
update for the 4.9.6.5 version.

Try including `mmsystem.h'. The lib is libwinmm.a (-lwinmm).

PS: XP crashed on me. It mentioned an erroneous or missing `hal.dll' (which,
on inspection, WAS present). I had to re-install. Documented?

[Dev-C++] PlaySound()

[The S. <we2...@at...>]

I'm trying to use the PlaySound() function for a project I'm working on. 
MSDN says to include windows.h, which I have done, and it still cannot 
find the PlaySound() inplementation. I've also been careful to include 
the correct *.a files, and still no luck.

If anyone has encountered a similar problem and might know how to fix 
it, please let me know. Thanks!

[Dev-C++] Compiling MySQL programs with Dev-C++

[Manoj S. <sha...@ro...>]

Hi,

I am trying to compile programs using the MySQL APIs and have been rather
unsuccessful at doing so. The problem seems to be that the library files
included with MySQL are VC++ compliant viz. libmysql.lib and
libmysqlclient.lib. I tried generating the corresponding .a libraries for
Dev-C++ using the dllwrap utility but that still doesnt work. I may be
needing the corresponding header files for MingW for them to work.

Has anyone successfully compiled MySQL programs using Dev-C++? I would
greatly appreciate it if you could help me out here.

Regards,
Manoj.

Re: [Dev-C++] ANSI c++ forbids implicit conversion from void in argument passing

you need to perform a cast on one of the parameters. possibly 
(HBRUSH)LR_DEFAULTCOLOR

What types are the values being passed?

I suppose you have Win32 SDK. Look for GetOpenFileName() and GetSaveFileName().
Don't forget to include commdlg.h
These functions are used to browse for files. If you want to browse for folders, 
you may either play with the above functions to dig out the dir, or use 
SHBrowseForFolder(). Read "Shell's namespace" thoroughly for details. It is a 
bit more complicated to use, but not so. It has a complete example for your problem.

[Dev-C++] linked list

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

Hello everyone!

As far as I know, there is no linked list implementation in the C standard 
library. If someone knows of a good implementation of a linked list (sorted or 
unsorted), please let me know. (C only)

Although I have made an implementation of it, I don't know what kind of 
interface would be good. I have made the following:

This is the header for my "list.h":

   typedef int (*compproc)(void*,void*);

   typedef struct _node{
     void* value;
     struct _node *prev;
     struct _node *next;
   }*pnode;

   typedef struct _list{
     int length;
     pnode first;
     pnode last;
     compproc cmp; /* if NULL, the list is unsorted */
   }*plist;

   /* list management */
   plist list_create(compproc cmp);
   void list_destroy(plist pl);
   pnode list_add(plist pl, void* value);
   int list_remove(plist pl, pnode pn);
   int list_length(plist pl);

   /* list utility functions */
   pnode list_search(plist pl, void* value);

If one wants to iterate through the list, a simple for will make it:

for(pnode=plist->first;pnode!=NULL;pnode=pnode->next){
   ...
}

The list is a doubly linked non-circular list (for fast operations).

The list is sorted with the cmp function, specified at the creation of the list. 
(the same as the cmp in the qsort() in C) At each list_add() the element will be 
automatically inserted sortedly. If NULL is given, the list will be unsorted.

My question is, is this interface is a good one, or should I make changes. The 
reason why I want to know this, is because I am making a library, which will 
contain this list, and I want to know whether it is useable well?
I will release this list implementation separately (for even you), if you think 
it is good enough.

ALL suggestions are welcome. Thank you.

You must not set WS_HSCROLL. And set WS_VSCROLL if you will need more space.

g++ is the c++ compiler, the three before it are related but I don't
know well about them.
c++filt is for options like strip symbols and such.
See command prompt> program --help.
gcc is the compiler for C, if you call it over a C++ code it will call g++.
mingw32- are the same that the ones without mingw32-, made so you can
have mingw and cygwin, and so you can differentiate both.

These seems that make something about controlling command options and
passing communication between compiler and linker... depending on the
kind of source you use.

[Dev-C++] affected makefile

[Thomas B. <tho...@te...>]

Hi,

I think I just solved it. I read some about makefiles and saw that by
including a makefile that contained

override OBJ=3Dobjects/*

it should work and it did, phew...Hopefully I can start working now,
thanks for the hints Abhijit and Per (du kanske =E4r svensk Per, is s=E5
fall s=E5 kanske tack =E4r p=E5 sin plats).
