Thread: alloca.h

I am porting some downloaded programs from visual cpp to devcpp. When compiled I get an error referring to “alloca” and an include for alloca.h . So I looked through the include dir nothing there. No alloca.h included with the zip. So I changed the alloca() to malloc(). It worked.

Question is alloca equivalent to malloc ? Need more infor on alloca. Is it specific to visual cpp ?

Question went here and here for mfc header files.

The Dev-C++ Resource Site

http://devpaks.org/

Microsoft Foundation Class Library - Wikipedia, the free encyclopedia

I have some source code asking for mfc header files when compiled but could not find them on any web site. Can I use mfc90.dll with devcpp ? Can I use vcl with devcpp ? Or mfc90u.dll ? meow.
I would still need the header files with the dll files ?

alloca - Google Search

Tip#31: alloca()

alloca() -- allocate space in the stack frame

msdn.microsoft.com/en-us/library/d06h2x6e(VS.80).aspx

did that. Where do I get the header files ? MFC comes with visual cpp this I know. Is there a MFC for dev cpp ? Cybercrimes <aka google syndication> is out to get me aaaawwww!

devcentral.iftech.com/articles/MFC/default.php
the only text item closes resemble what I looking for and it all visual cpp.

MFC Tutorial Part 1

does dev cpp have mfcsdk ?

Code:

 Step 3:
    Copy and paste the code below. 

//MFC1.CPP - MFC Tutorial Part 1 from codersource.net

#include <afxwin.h>

class MFC_Tutorial_Window :public CFrameWnd
{
public:
    MFC_Tutorial_Window()
    {
         Create(NULL,"MFC Tutorial Part 1 CoderSource Window");
    }
};

class MyApp :public CWinApp
{
   MFC_Tutorial_Window *wnd; 
public:
   BOOL InitInstance()
   {
        wnd = new MFC_Tutorial_Window();
        m_pMainWnd = wnd;
        m_pMainWnd->ShowWindow(1);
        return 1;
     }
};

MyApp theApp;

//End of program MFC Tutorial Part 1

Step 4:
   Now compile the application. It will generate linker errors. The reason is because the MFC libraries are not yet linked. 
   Do the last step of this MFC Tutorial.
Step 5:
Select Menu -->Project --> Settings and General tab. On the first combo box "Microsoft Foundation classes" and select "Use MFC in shared dll".
   Now compile and run the program.

how to do this with dev cpp ?

edit
missing all mfc header files like mfcvfx.h mfcwin.h etc.

Code:

here are some of the errors with the missing headers. It is a large project demo. I think I will have to re do this program in ansi c . With no mfc. It looked like a real nice demo.

although, the free version doesn't have MFC

I will stay with free ware. Thank you.
