QLB libraries

[jakykong]

ok so LIB.exe is pretty easy to use for my needs.
I am using the C programming language to make functions and subs for qbasic to use instead of and in addition to qbasic commands to allow for qbasic to be a much lower-level language but still have the higher-level functions. Ok, so that is what i am doing. The problem i am having is getting my C functions to work in qbasic. I can compile them to an object file, then put them into a library, but the library is not a qlb library, and i can't figure out how to make it into one. I know it has to do with LINK but i can't find any documentation at all on the command line parameters of LINK, so i have no idea how to use LINK to make a LIB into a QLB. Can anyone help me with this?

Have you tried MultiLib yet? It's a QuickBasic library utility. Just Google for MultiLib QBasic if you want to check it out.


Here's the direct method to make a .QLB file from a .LIB file...

Code: Select all

LINK /Q MyLib.LIB, MyLib,,BQLB45;

[jakykong]

cant fine the multilib program anywhere! it looks to me like it is not available yet but will be...  Anyway, the LINK command gave me **32** errors in the process and i renamed the files to match the command exactly...
i'm going to try recompiling the OBJ file, but if that doesent work, i dont know what to do!

[Dr_Davenstein]

Well, are all of the other files in the same directory? I mean LIB, LINK, BQLB45, etc...

It would require that all of those be in the same folder. It can also get real messy if the OBJ files are in different dirs. I'll see if I can find that link to MultiLib. It was kinda hard for me to find too. ::)

[jakykong]

yeah, all the files are in the same folder. i downloaded the qb45 install diskettes and installed with the setup program. no alterations were made to the files in the dir(only new ones were added). The list file that i got running your command(LINK /q hello.lib, hello,,bqlb45) contained 32 errors. the list file contained all the below:

BQLB45.LIB(..\rt\ulstart.asm) : error L2025: _main : symbol defined more than once

and just in case you need to know, i compiled my OBJ file with Miracle C(get it at dowlnoad.com). i compiled this source code(exactly):

#include <stdio.h>
int main()
{
printf("Hello, world!");
return 1;
}

and that is what i have so far.

[jakykong]

also, if you have AIM then we can go onto AIM and you could give me the multilib with a file transfer in aim... my screenname is the same on AIM as this forum...

[jakykong]

ok so i found the Multilib program(and figured out how to use it). but it gave me the same errors as the LINK command did, and really wasnt any more help than anything else... i think it may be something with the bqlb45 library that isnt liking my C obj file... do you know of any C compilers for DOS that will make an OBJ file that Qbasic will work with?

[Dr_Davenstein]

Have you tried using a 16Bit compiler?

Here's a link to Borland's old stuff...
http://community.borland.com/museum/

You might try compiling with that and see if it helps.

[jakykong]

i only got one error that is _printf is an unresolved external. Qbasic starts with it, but i run into one problem:

DECLARE SUB main CDECL ()
CALLS main

causes the whole command window to close and return me to my windows 2000 folder tree screen. by declaring it without CDECL it gives me an error. The code i compiled was nothing but this:

#include <stdio.h>
main ()
{
&nbsp; printf("Hello, world!\n")
}

and that should be the same as the qbasic statement:

PRINT "Hello, world!"

but it stops the whole thing and closes my window.

[jakykong]

ok so that isnt the problem any more. i ran the command window in full screen mode to find out what errors i would get. The NTVDM(or something) CPU encountered an illegal operation at some long address... so i think it is a compatability thing. I am going to try the same thing on my 486 and see if that changes it...

[Guest]

If it's 32bit then it probably won't work with quickbasic
since it's 16 bit.

You might try using QuickC

[jakykong]

QuickC... never heard of it. it's a 16 bit C compiler for DOS i am assuming... know where i can get a copy?

[Dr_Davenstein]

You could try that link that I posted up there. It's not QuickC, but it's a 16Bit DOS compiler. It's called TurboC, by Borland. It's extremely easy to use and it's free... and plenty fast too

[Guest]

QuickC. MS C answer to QuickBasic.

It's around.

I don't think it sold much (relatively speaking of course).
I don't know how good/bad it is, but it should be compatible some way with QuickBasic I would think, perhaps commented in the help file if/when you find it.

[Dr_Davenstein]

Oh god... ::)
I can't believe I didn't notice that. QuickC...QuickBasic... ;D
I'm gonna have to check it out too.
