I think the problem is the space in the filename ("Program Files"). Try
installing to another location (maybe "c:\dev-cpp").

[Dev-C++] "unable to run program file"

[Kylotan <ky...@ky...>]

I just installed the latest version, 4.9.5.0, and upon trying to compile
any program, I get this error in the 'Compiler' pane:

2 C:\My Documents\2 unable to run program file.

And this in the Compile Log:
Executing  g++.exe...
g++.exe "C:\My Documents\test2.cpp" -o "C:\My
ocuments\test2.exe"   -s  -I"C:\PROGRAM
ILES\UTILS\DEV-CPP\include"  -I"C:\PROGRAM
FILES\UTILS\DEV-CPP\include\g++-3"  -I"C:\PROGRAM
FILES\UTILS\DEV-CPP\include"   -L"C:\PROGRAM FILES\UTILS\DEV-CPP\lib"
Execution terminated

I accepted the default installation options, with the only exception of
not associating files with Dev C++ and changing the directory of
installation. I've checked the FAQ and scanned back through a few weeks
of the archives but I don't see anything like this. Any idea what the
problem is?

No, that's not the problem, GCC and related tools use '/', and it *is*
valid. Try this:

    dir "c:/"

and it will work. The error must be because of a missing file or an invalid
installation path. Do compiles without external resources work properly?

[Dev-C++] Mysql++ static libs for DevCpp

[<Met...@ao...>]

Hi there

Has anybody succeeded in compiling a static lib version of Mysql++ to use it 
with DevCpp ? Just downloaded it, and I get a *huge* amount of errors in the 
includes, even though the pathes seem to be ok...

Mysql++ is shipped with a ".lib" version of the static lib, which I cannot 
unfortunately use with DevCpp. Or is there any way to convert this MS-type 
.lib into something usable by DevCpp ?

Kind regards

 You're compressing the .tar, no?

 A nice improvement anyway, but that seems to require the use of 
'tar' to create something solid to compress? I like that about rar 
that you don't have to do that.

RE: [Dev-C++] Re: 7-Zip

I am talking about the last beta. Here is what happens in my system both
with maximum compression and solid archive:


21/08/2002  01:24 =EC=EC         4.396.125 mingw-1.1.7z
21/08/2002  01:22 =EC=EC         6.902.389 mingw-1.1.rar



For MINGW1-1 it's about 33% more compression. The half size was at GCC
3.2 core files.

[Dev-C++] Problems with error 120, calling listview funcs

[<Met...@ao...>]

Hi there

I'm trying to set up some columns and items in a list view control item on a 
Win98SE machine.

Unfortunately, each time I send the LVM_INSERTCOLUMN or the LVM_SETITEM 
messages, I get an error 120 "Only available in Win32 mode". I cannot 
understand such an error, the progs compiles and links fine. 

The messages I can find browing google groups says something like these 
messages could only be implemented on NT based systems. But the SDK does not 
say anything about this.

Anybody could help ?

Kind regards

Good.

It is the same sort(). It uses < as default. If the default works do not
use a comparison function or function object. The default is usually
more optimised. Also try to make the operator<() inline (either a member
function or a regular function).

The most important: Printing on the screen introduces tremendous time
cost. Probably it is more expensive in Windows than Linux. So rremove
all those couts from Fib(). This will make the benchmark more accurate.



Finally as you know using a loop is faster than using recursion. Also
recursion occupies more & more space in the stack, and for large
"depths" you will be without space in the stack. Loop has not this
problem too.


But this is left as an excercise for you. :)


Finally, although these drawbacks, i can't leave this code as it is
without taking advantage of the power of C++.

 With the addition of a time measuring mechanism, the removal of of
those couts from inside Fib(), and making the Fib() inline we have the
code:


#include <iostream>
#include <cstdlib>
#include <ctime>

inline int Fib(int n)
{
 using namespace std;

 if (n<3)
  return (1);

 else
   return( Fib(n-2)+Fib(n-1));
}

int main()
{
  using namespace std;

  int n, answer;
 
  cout <<"Enter number to find: ";
  cin >>n;
  cout <<"\n\n";

  clock_t t1=clock();

  answer=Fib(n);
  cout << answer <<" is the " << n <<"th Fibonacci number\n";

  clock_t t2=clock();


  cout<<"It took "<<t2-t1<<". Translated in seconds: ";
  cout<<static_cast<double>(t2-t1)/CLOCKS_PER_SEC<<endl;

  cin.ignore();

  return 0;
}


Compile it with the optimisation switches and tell me  the results. :)

The mistake was that the vector was still instantiated with PlsLine *, not
with PlsLine. It's working now, thanks. Just for the record, the other form
of sort() which takes a comparison function also works, as Eddy said.

Of course it works... it's meant to :).

[Dev-C++] Linux vs Windows speed

[jgana <jg...@vt...>]

First, thanks to everybody for your help
Second, forgive me, if I am asking something stupid=85You know, I am
learning.

I found out that a console program that is compiled with Dev-C++ (Mingw)
can run perfectly well in Linux and a lot faster. The program runs ~70%
slower in Windows.=20
Why there is a difference in speed if I am using the same machine?
(Pentium 400 MHz)=20

The program that I used is a very inefficient way to calculate the
Fibonacci Series. But, the point was to have a rough idea of the speed.
The Dev-C++ (Mingw) executable in windows took 1 minute 45 seconds in
finding the 22th element of the Fibonacci Series (17,711). The same
executable in Linux took 30 seconds to find the 22th element.
=20
#include <iostream.h>
#include <stdlib.h>

int Fib(int n);

int main()
{
  using namespace std;
  int n, answer, stop;

 cout <<"Enter number to find: ";
 cin >>n;
 cout <<"\n\n";
 answer=3DFib(n);
 cout << answer <<" is the " << n <<"th Fibonacci number\n";
