[Dev-C++] Problems compiling

[Jodie a. H. W. <har...@ro...>]

Hi

I am just starting to learn C and when I compile the following simple
program I get the following error message.

#include "stdio.h"
main ( )
{
  printf("This is a short C program.");
}


Compile Error:
Line 2   File C:\Work\2    Message  unable to run program file


Could someone please tell what I'm doing wrong.

Don't you have more error output? One of the outptu tabs should display
what file it isn't able to run.

Anyway, your main() function should return int - don't use old style with
implicit int for missing data types - and you should return a value too.

int main(void) {
    printf("...");
    return 0;
}

Don't ever create projects in folders with spaces in the name.

[Dev-C++] Simple question about using libraries

[Adam R. <dan...@o2...>]

Dear Dev-Cpp users,

I've built boost C++ library (using their bjam utility), for MinGW compiler.
What the build process produced are files with extension .lib, .obj and
.dll.
My question is:
        how to link against these files?
(Especially how to link .lib and .obj files)

Does Dev-Cpp give any support for it? In that case what command line
parameters should I use (I guess for the linker, ld.exe)?

Thank you for help!

You put the DLL files where windows will find them (the directory of 
your program or maybe c:\windows\system32, etc.)

Then you add this small lib file of the same name to your project in the 
linker settings. ALternatively, you can add the dlls to your project too 
if you want.

.o files are just intermediate files before the linker puts them all 
together to a lib, dll or an executable.

hey all,
whoever compiled those Boost libraries didn't compile
them for MinGW. i've compiled Boost regex library
before, and i got .o, .a, and dll files. using dlls
from C++ is a pain in the ass because of name
mangling. unless the functions are all wrapped in a C
function, you'll have problems using the DLL.

as an aside, i'm looking for Python MinGW builds. the
workaround i have is to study the python headers and
call functions directly from the Python DLL. so far
i've not been able to build Python with MinGW. the
only other option i have is to use Cygwin Python
libraries, which would work fine, except for the
cygwin.dll dependency.
