Hi folks,
i thought to give C::B a try along my OGRE project. Tried to compile some of my old console code that i have developed under Borland Builder 5 but encountered a problem with the _setcursortype(); function.
Actualy the cursor don't do what it supposed to do and i don't know why.
When i compile my hello world app with _setcursortype(_NOCURSOR); the cursor appears like this:
(http://www.dreadnoughtproject.org/heinrich/Media/Images/ForumPics/nocursor.jpg)
Not that it just appears as a normal cursor it also appears on the top of the line and not on the bottom of it :?
When i compile it with _setcursortype(_NORMALCURSOR); the cursor appears not as a normal cursor but as a half solid cursor !!!
(http://www.dreadnoughtproject.org/heinrich/Media/Images/ForumPics/normalcursor.jpg)
When i compile it with _setcursortype(_SOLIDCURSOR); it appears as its supposed to:
(http://www.dreadnoughtproject.org/heinrich/Media/Images/ForumPics/solidcursor.jpg)
I tried it with GNU and also Borland 5.5 compiler but with the same results
I have no clue WTF is wrong :?
Anybody ?

_setcursortype() is not ANSI/ISO C neither POSIX standard.
It came with conio.h provided with old borland compilers, it's not standard, and obviously not portable.
Do you really need that non-standard non-portable functionality?

Didn't knew that. Thanks.

If there is no ANSI compliant equivalent then yes! Is there any ?
Is there a way to let the Compiler use this old conio.h ?
EDIT: Is there any online documentation or docs for download that explain all the functions of the ANSI .h's ?

Not that I know, probably not, because it's not something portable.

I don't know but I wouldn't advice that.
EDIT: Is there any online documentation or docs for download that explain all the functions of the ANSI .h's ?
Yes, here http://www.cppreference.com/ or here: http://www.google.com :)

Deamon use conio2 this is an opensource project on sourceforge.net http://conio.sourceforge.net/ (http://conio.sourceforge.net/)
it is very useful

Thanks. But it looks like it doesn't describe all the C++ headers.

Hey conio is back ! :) Found it just yesterday. This is great actualy, cose my console app builds heavily on it. It's so damn handy.
How to make it work with C::B ?
Is it enough to just drop it in to the include folder of gcc or Borland 5.5 ?
And what do i do with the DevPack file of it ?
EDIT: BTW is there a way to change the resolution of the console ?

C::B has a plugin for it, i.e., Dev-C++ DevPacks updater/installer :).

Sorry for my newbishness but what am i supposed to do with this DevPack now ?
Should i put it into some folder or open it with what ?

Hello,
There are (IIRC) one or two posts which should help you out. Try a search on the Code::Blocks forum.

Ok i unziped the devpack but one question remain: How do i make the conio2.h run ? I putted it in to the include folder of the Borland 5.5 compiler but when i include it in the code it gives me error messages. I also tried to include it from another folder but with the same results:
Error E2238 D:\Programme\DevPack\conio_content\include\conio2.h 30: Multiple declaration for 'BLACK'
Error E2344 D:\Programme\CodeBlocks\share\CodeBlocks\plugins\compilers\BCC55\Include\conio.h 56: Earlier declaration of 'BLACK'
Error E2238 D:\Programme\DevPack\conio_content\include\conio2.h 31: Multiple declaration for 'BLUE'
Error E2344 D:\Programme\CodeBlocks\share\CodeBlocks\plugins\compilers\BCC55\Include\conio.h 57: Earlier declaration of 'BLUE'
Error E2238 D:\Programme\DevPack\conio_content\include\conio2.h 32: Multiple declaration for 'GREEN'
Error E2344 D:\Programme\CodeBlocks\share\CodeBlocks\plugins\compilers\BCC55\Include\conio.h 58: Earlier declaration of 'GREEN'
Error E2238 D:\Programme\DevPack\conio_content\include\conio2.h 33: Multiple declaration for 'CYAN'
Error E2344 D:\Programme\CodeBlocks\share\CodeBlocks\plugins\compilers\BCC55\Include\conio.h 59: Earlier declaration of 'CYAN'
Error E2238 D:\Programme\DevPack\conio_content\include\conio2.h 34: Multiple declaration for 'RED'
So how to make it run ?
Is it meant to run only with MingW compiler ?
I also tried it with MingW, means i putted it in to the include folder of MingW but it then complains:
.objs\main.obj(.text+0x24):main.cpp: undefined reference to `_setcursortype'

From here (http://conio.sourceforge.net/docs/html/index.html), did you:
2. Link with libconio.a (add -lconio parameter to linker).

Me idiot. Thank you so much. It works now. Well, kinda. It display _NOCURSOR as a _NORMALCURSOR and _NORMALCURSOR as a half _SOLIDCURSOR and _SOLIDCURSOR as _NOCURSOR. :?
Anyone experianced the same ? Do i still do something wrong ?
When i open conio2.h and change this values:
#define _NOCURSOR 0 /**< no cursor */
#define _SOLIDCURSOR 100 /**< cursor filling whole cell */
#define _NORMALCURSOR 20 /**< cursor filling 20 percent of cell heigh */
to:
//#define _NOCURSOR 100 /**< no cursor */
//#define _SOLIDCURSOR 99 /**< cursor filling whole cell */
//#define _NORMALCURSOR 10 /**< cursor filling 20 percent of cell height */
It finaly works properly. Still it's weired !
BTW: Talking about -lconio parameter. Is it right to put it to Settings -> Compiler -> Linker tab -> Other linker options field ?
And when ever i want to put several parameters is the "-" enough to separate them from each others or is a "," necessary ?

Hello,
May be you can try the conio forum and/or mailing list, though they seem not very active :(. Look at here (http://sourceforge.net/projects/conio/).
You can also try to report (http://sourceforge.net/tracker/?atid=673250&group_id=115967&func=browse) the problem ("bug") you have.
Best wishes,
Michael

Well, libconio.a would be -lconio :). Simply add the libconio.a to the linker-->Link libraries and the directory path into the directories-->Linker.
Best wishes,
Michael
