Why does dev c create an exe file for windows

Dev-C++ FAQ

How are you running the file, from the C Prompt? What are you typing? Does the file name have any spaces or special charcters? Are you administrator? In the folder with your program type Dir and make sure the filename looks right. Make sure the file is not open in notepad or something. I've found that generally, the correct answer is don't use Dev-C because it's a steaming pile of bleep but this would also work. I tutor students that are required to use this compiler and this problem happens with great frequency, even when not using the C: directory as Jon indicated above. Alternatively, you can take the makefile that is automatically generated by Dev C and alter it, saving it under a different file name, like 'myprojectrelease.win'. What you'd do is alter it to remove command line switches like -g, -g3 or other similar flags that enable the. I am trying to write a program in C using Dev-C 5.6.1. I go to compile the program, and nothing happens. It compiles with zero errors, zero warnings, and an output of 0 bytes (it doesn't even create an exe file, nor any of the.o files). May 29, 2009 In Dev-C (at least) you can run a single-file program without making a project, which is very nice for experimenting with language features or running programs posted by people on this site. It also starts up quickly. However, Dev-C is otherwise not recommended since it is no longer in development. So it shouldn't be the only IDE you have.

5. When I compile a file, I get a message saying'could not find <filename> '
6. The EXE files created are huge. What can i doto reduce the size ?

1.When I compile my dos program and execute it, Dev-C++ minimizesand then restore in a second but nothing appears ?
When creating a console application, be sure to uncheck “Donot create a console” in Project Options (when working withsource files only uncheck “Create for win32” inCompiler Options).

2.When executing my dos program, it closes automatically. How I canchange this ?
You can use an input function at the end of you source, like thefollowing example :
#include<stdlib.h>
int main()
{
system(“PAUSE”);
return0;
}

3.After linking, i get the error“C:DEV-C++LIBlibmingw32.a(main.o)(.text+0x8e): undefinedreference to `WinMain@16'
You probably haven’t declared any main() function in yourprogram. Otherwise, try recompiling a second time.

4.When I launch Dev-C++ i get the message saying “WININET.DLLnot found” ?
If you are missing WININET.DLL on your Windows system, you candownload it at: http://www.rocketdownload.com/supfiles.htm

5.When I compile a file, I get a message saying 'could notfind <filename> '
Check in Compiler options if the direcories settings are correct.With a default setup, you should have :
C:DEV-C++Bin
c:DEV-C++Include
c:DEV-C++Include
c:DEV-C++Lib

6.The EXE files created are huge. What can i do to reduce the size?
If you want to reduce your exe file size from 330 Ko to 12 Ko forexample, go to compiler options. Then click on the Linker pageand uncheck 'Generate debug information'. This willremove debugging information (if you want to debug, uncheck it).You can also click on Optimization page and check 'Bestoptimization'.

7.Under Windows NT, every time i launch Dev-C++ i get the message“Failed to set data for”
The is because you are not in Administrator mode, and Dev-C++tries to write to the registry. To get rid of the error message,log on as the Administrator, or uncheck the file associationoptions in Environment options, Misc. Sheet.

8.when I try to compile I get: ld: cannot open crt2. o: No suchfile or directory. What can i do ?
Go to Compiler options, and check if the Lib directory iscorrectly set to:
C:Dev-C++Lib
(for a default installation).

If this stilldoesn't work, try copying the file Libcrt2.o to your Dev-C++'sBin directory.

9.How can i use the OpenGL library and others ?
All the libraries that comes with Mingw reside in the Libdirectory. They are all named in the following way: lib*.a
To link a library with your project, just add in Project options,Further option files :
-lopengl32
This is for including the libopengl32.a library. To add any otherlibrary, just follow the same syntax:
Type -l (L in lowercase) plus the base name of the library(filename without 'lib' and the '.a'extension).

10.When i compile a file that contains references to Windowsfilename (like <Mydirmyfile.h>), i get a 'unrecognizedescape sequence' message ?
