That line should be:

void CreateEmployee( struct Employee[], int); //prototype



A struct keyword by itself doesn't mean anything to the

compiler.  You have to follow it with an already defined struct

name.  Another problem is that you use the name struct Employee

in your function, but you never define a struct Employee.  You

define a struct Emp, perhaps that should be struct Employee?

Also, you'll need to move the definition of the struct before the

definition of the prototype in order for the prototype to work.



Some rules of thumb:

Your prototype and function definition should

be nearly identical.

Usual order of program files:

  #include's

  constant defintions (#defin or const)

  Structure declarations/typedefs

  Function prototypes

  Code



Hope this helps.

[Dev-C++] update on dev

[<gen...@ya...>]

it seems the prblem is with directx 9. when only the allegro devpak was installed (all directx devpaks were deleted), it could not find the directinput library. reinstalling the directx 9 devpak from webupdate gave the same directsound errors. removing the allegro, directx 9 devpaks, and the command to link in the directinput library, and reinstalling just the allegro devpak caused another set of linker errors. the linker couldn't find the directdraw lib.
 
thanks in advance again for any help

[Dev-C++] a few prblms w dev

[<gen...@ya...>]

hi everyone,
 
i have a few problems with dev-c++. okay, i was using the templates to create a few sample programs, and tried compiling the static Allegro template as-is. it kept giving linker errors, mainly about directsound function calls being undefined. i changed the order of the libraries, leaving the '-lalleg_s' for last. more link errors. the dll version worked okay.
 
---
 
i downloaded the openal devpak using webupdate, and whenever i tried compiling the example program, it always passed a parameter to the compiler: "-fmessage-length=0", which kept the compiler screaming bloody murder (okay, it was screaming 'invalid option'). the same thing happened with a program i wrote, and i had to manually edit the makefile, remove the parameters to the compiler (it's okay for the linker), and make the makefile read-only to get it to work.
 
---
 
which directx9 devpak is 'official'? there's one you can get from http://gproductions.dazart.de, and another you can get from webupdate. it seems none of them actually work for me.
 
---
 
the eFLTK devpak template complains about undefined references, mainly to operator delete(void *).
 
my dev version is 4.9.8.9, gcc 3.2
 
advTHANKSance for any help

1.  Don't use ".h" files in a C++ program.  Change those to cstdlib 
and cstring.  Assuming, of course, that you really want to use C 
strings.

2.  Your prototype for CreateEmployee needs to be after you define 
what a "struct Emp" is so that you can put "struct Emp" in your 
parameter list.

3.  Your parameter list needs a pointer to a "struct Emp" not just a 
"struct []".

4.  You're not setting the employee id based on the subscript into 
the array.

5.  You're setting the employee id to 0 for all employees.

There are probably other things that I'm not seeing in a cursory 
glance.  I made these mods and the code ran correctly.

[Dev-C++] How do I uninstall, upgrade, add Insight, add Corona?

[Joanna F. <jf...@ve...>]

I have Dev-C++ Version 4 (build on 9/10/2000, Mingw compiler 2.95.2-1
MSVCRT, GNU Debugger 4.18), and it was working just fine (on a Dell
Dimension 4600 PC w/ Pentium 4, running Windows XP Pro), until I messed
it up by trying to add Corona-1.0.2-vc6 Image I/O to it.  

 

I think I should I uninstall and upgrade Dev-C++ and get Redhat's
Insight GUI to go with the GDB.  

 

Can you direct me to instructions for uninstalling properly?  There is
no uninstall program in my Dev-C++ for some reason.

 

Can you tell me what version of Dev-C++ to download and install so I can
use Insight?  

 

Can you tell me how to include Corona properly? Or should I get
different image I/O software?

 

My aim is to write a program that will import an RGB image file,
manipulate it pixel by pixel, and export a changed image.

Re: [Dev-C++] pointers to member functions

[<gen...@ya...>]

AFAIK - A Far A I Know. lol

you can make it protected in the parent class, and use
an accessor method to call it. if you inherit as
public, it remains protected in the child class.
(protected is much like private, except derived
classes can access them. derived classes cannot access
private members). if you inherit as private,
everything inherited (public and protected members)
become private to the derived class.

Re: [Dev-C++] pointers to member functions

Hi,
I have just controlled:
in Parent class the pointer is public, and the child class is defined as:

class ChildClass: public ParentClass etc...

(It'isn't very elegant, but what I'm doing now is to call an inline function
that contains only that pointer, so I can use it.)

[Dev-C++] pointers to member functions

[michele <mic...@li...>]

Question about pointers:

// A class named 'MyClass' inherits from its parent class a pointer of this
type:

    void (ParentClass::*p)(int variable);

// inside a member function this is right:

    (this->*p)(variable);

// outside (es. in main function):

ChildClass *MyClass=new ChildClass;

 (MyClass->*p)(variable)    // doesn't work (compiler: "p undeclared")


Is It possible to call this type of pointers outside member functions?

i tried downloading the 4.9.8.9 update from the main
site, i found out it had gone down, and of course,
Andreas' site. that left only the PlanetMirror site.
to my suprise, the update had been added there, to
replace the old one.

can we have a unified devpak repository? devpaks.org,
planetmirror.com, etc? can we have somewhere where
it's all sync'd? so we don't wonder which is the
latest, etc, etc.

dev-cpp doesn't have a layout any other than standar mingw bins. The 
.tar.gz's provided by them were just untarred to c:\dev-cpp directory. 
No paths were changed.

yes. but some c++ programs will require paths like:
lib\gcc\mingw32\3.4.0\include
(this one is in gcc-core-3.4)
which contains mingw version - currently in dev-cpp it's by default hard 
set to:
lib\gcc-lib\mingw32\3.2\include

For more details look at bug 910098 reported by kidkat and links to 
mingw from there.

Due to the stupid layout of Dev-C++'s MinGW "bundle", paths have to be=20
adjusted, otherwise the compiler will not find it's headers and=20
libraries. If you just do as I posted before, everything will work=20
correctly, without adjusting anything. The compiler is packaged to find=20
it's own (standard C and C++) headers and libraries automatically if=20
everything is put in the right place: that is, where the installer puts=20
them.

gcc 3.4 has nothing to do with

gdb
w32api
mingw-runtime
make
binutils

Those are separate packages, not needed to be upgraded to use gcc 3.4
Besides, the right way of upgrading is unzipping. If you ever took a=20
look at the inner layout of the .tar.gz archives of the MinGW packages,=20
you would have noticed, that they all have the same directory layout,=20
which is the same, that is created by the installer, so unzipping will=20
not create any mess anywhere. It will make everything get to the right=20
place.

gcc 3.4 works like a charm for me, and it took less than 20 seconds to=20
upgrade after download.

AFAIK when you create a c++ project you have to adjust your include 
paths to match mingw version (currently it's 3.2)

According to this page:
http://www.bloodshed.net/dev/devcpp.html
this is the mingw that was used:
ftp://ftp.nanotech.wisc.edu/pub/khan/gnu-win32/mingw32/snapshots/gcc-3.0-1/

AFAIK those components were used in current dev-cpp 5:
gdb-5.1.1-1-mingw.tar.gz
w32api-2.2.tar.gz
mingw-runtime-2.4.tar.gz
make-3.79.1-20010722.tar.gz
one of gcc-3.2 releases (with patches?)
one of binutils-2.13.90 releases (with patches?)

so basicly you would need to update those.

I think it would be good to start testing those and see the what's 
happening. mingw gcc 3.4.0 is still a cadidate.
I think it would be fairly easy to create a packman entries and then 
devpaks for with mingw components and then just upgrade them. This 
wouldn't make
as big of a mess than just unzipping the components.
Maybe I'll spend some thime on that and post the results later here....

No.

Here's what you can do, as a last resort:
Completely delete everything from
Dev-Cpp/bin
Dev-Cpp/lib
Dev-Cpp/include

Download the latest installer version of MinGW. Install it.
Add <MinGW installation path>/bin to you PATH environment variable.

Now, unpack the two gcc 3.4 upgrades (gcc-g++-3.4.0-*** and=20
gcc-core-3.4.0-***) into the MinGW install, overwriting everything.
I also recommend to download the latest W32Api (2.5 is the latest, as I=20
remember), and also unpack it (though it is not needed for gcc 3.4 to wor=
k).

That's it. Now you don't even any compilers to be set up in Dev-C++, as=20
it will be automatically found, because <MinGW>/bin is added to the=20
path, and gcc will find it's own includes and libs automatically.

looking at the image you provided I can see that you are using Dev-C++
version 4. I would strongly suggest upgrading to vesion 5, available
from the Bloodshed website, you can then use the update manager as I
previously  wrote.

I believe you have to uninstall your version 4 before installing
version 5.

If you choose not to update your devcpp then point your browser to
http://public.planetmirror.com/pub/devcpp/ and download the MySQL
devpak. I am not sure if this works correctly with version 4, then use
the package manager (ctrl+F12) to install the pak.
