I need crtdll.inc or replacement

[Ran]

Hello,

I did find a masm32 project where crtdll.inc and crtdll.lib is needed.
I did search the Web but cannot find it.
I did find crtdll.lib!
So I think there must be a replacement(s) for this older? crtdll.inc.
But which one(s)?

Greetings,

Ran

Hi Ran,

The attached zip file contains crtdll.lib and crtdll.inc

Hi Vortex,

It's is good to hear from You again.
I am not often on the board but everytime I am You get me out of trouble.

Thanks a lot,

Ran

Hello Ran,

You are welcome. I am glad if I could be helpful.

Hello Vortex,

I have some info about the crtdll.inc and crt.lib You sent me.

When assembling I got the following errors:

- atol error A2111 conflicting parameter definition
               A2112 Proc and prototype calling conventions conflict
- isalpha     idem
- islower    idem
- isupper   idem
- div error syntax error PROTO
-fabs idem

But since I do not use this functions I deleted them from crtdll.inc

Linking the crtdll.lib gave me following problem:

fatal error LNK1115: / MACHINE option required

But on http://search.cpan.org/src/SREZIC/Tk-804.027_500/PNG/zlib/contrib/vstudio/readme.txt
I did find the link: http://www.winimage.com/zLibDll/crtdll.zip
where I could download another crtdll.lib and this one is much bigger = 499 Kb
Anyway this new crtdll.lib did disappear my LNK1115 error.
Now my program runs happely!  :U

This is just informative because I tought You have to know this problems with crtdll.

Best of greetings and thanks again,

Ran

If I try to combine crtdll.inc with masm32.inc and macros.asm, there are conflicts on lines:
320
337
339
341
342
345
354
359
360
364
368
378
383
387
454
Which are easy enough to get around, but even modifying the LINK command line I could not get around the:

LINK : fatal error LNK1115: /MACHINE option required

Michael,

Did You try to replace Your crtdll.lib in masm32 with the one from:

http://www.winimage.com/zLibDll/crtdll.zip

This way I got rid of the "LINK : fatal error LNK1115: /MACHINE option required" error.

And try the crtdll.inc from Vortex above, it gives a lot less errors. (errors line 320-337-341-378-383-387)

Hi Ran,

I am sorry for the trouble. To create the import library, I used Pelle's librarian Polib. For the include file, I used the lib2inc tool. I will analyze the import library you found.

[MichaelW]

Ran,

There is no crtdll.lib in the MASM32 package. The library that you linked appears to be a static library, judging from the size and the presence of object module names. I did not attempt to use it because I have no need and because it is from an unknown (to me) source. Is there some reason why you cannot just use the MASM32 msvcrt.lib and include file?

[Ran]

Michael

Then I got a lot of unsupported symbols like
free
malloc
strlen
strcpy
strcat
_kbhit
_getch
_getche

Ran

[MichaelW]

For the MASM32 msvcrt.lib all of the function names have a "crt_" prefix. So the correct names are:

crt_free
crt_malloc
crt_strlen
crt_strcpy
crt_strcat
crt__kbhit
crt__getch
crt__getche
etc

The prefix was added to eliminate name conflicts with the MASM32 library and macros, and with some of the instruction mnemonics (div and fabs).

[Ran]

OK, Thanks Michael,

It is perhaps better that I replace the crtdll with the msvcrt lib.
That's why I asked for "or replacement.
I'm not using masm a lot so I'm not at home with the masm libs.
I do like asm programming but I do need a purpose to use it.
I other words, if I have a project, I code.
And I am more into C.
My problem with asm is that I never found a good (simple) tutorial about the use of floating point math.
That's what's holding me back.

Greetings,

Ran

The MASM32 package includes a FPU tutorial by Raymond Filiatreault that IMO is excellent. Look in masm32\tutorial\fputut.

Hello Ran,

Introducing the crt_ prefix, I modified crtdll.def to avoid those conflicts :

Code Select Expand

LIBRARY crtdll
EXPORTS
crt_HUGE_dll
crt__CIacos
crt__CIasin
crt__CIatan
.
.


After, I rebuilt crtdll.lib with the new symbols prefixed with crt_ in crtdll.def :

Code Select Expand

\masm32\bin\link -lib /OUT:crtdll.lib /DEF:crtdll.def /MACHINE:IX86
del crtdll.exp
rebuildlib crtdll.lib -l4


Attached contains a working example. The size of the final import library crtdll.lib is 340 Kb.

Thanks a lot Vortex,

I will put it to good use.

But Michael and Vortex, I have to ask You another question:

Using C run-time functions, is that done or not done in a masm environment if You think about speed ?
Are this functions optimised?
And if not done, do You make Your own functions or is there an existing database with optmised asm functions?

Just asking

Thanks a lot guys,

Ran
