masm with spinx c--

[Emil_halim]

Hi Vortex,

I have no experience of anti virus  Seriously , so i  downloaded  avira anti virus and starting scan my system.

deleted done.

does avira repare  that problems. 

[TWell]

I use Avast free scanner, no actual virus in that zip ?
That might be heuristic problem again ?
So, what file inside zip is infected ?
Colfire.exe ??

VirusTotal Detection ratio: 4 / 48

CAT-QuickHeal    (Suspicious) - DNAScan    20131018
Comodo    MalCrypt.Indus!    20131018

@Emil_halim
You could split that package to smaller parts.
Let people download OllyDbg if they wish.

Hi Emil,

Me too, I am an Avira user but no any AV can provide 100% guarantee. Scan all the drives of your computer and be sure that you have a safe programming environment.

[avcaballero]

I've got that av warning in some c-- progs examples, though I assumed a false positive. It is very usual in no common tools? in tinyc many times too. One way to avoid such false positive is providing just the code and the compiler... Or just the source codes in "unsafe" exes...

Regards

Hi TWell,

after installing anti virus it has detected some virus , just like you post , the file  Colfire.exe  is infected .

but there is 2 exe of that file one is downloaded from net , the site i was posted later of sphinx c-- , and the
other is compiled in my system and has no virus.

any way i will check all exe in the zip file and repost again.

@Vortex

ok , i am doing.

@ avcaballero

thank you , all programs in example was downloaded from the site of c-- , i will check them all.

Hi all,

Okay  here is a clean zip file.

download here http://speedy.sh/aDd4G/Ext-c.rar

Enjoy codeing c-- & masm.

[Vortex]

Hi Emil,

Not to be pedantic and no offence but you don't need a site like that to share your code :

Download this file for free using Tiny DM manager (exe app)

It asks to use a download manager.

Kindly, could you delete all the executables in your archive? You can attach here the resulting zip archive.

Hi Emil,

Not to be pedantic and no offence but you don't need a site like that to share your code :

all your advises are be welcome any time.

here is an other like http://bcxdx.spoilerspace.com/C--/Ext_c--.rar

Hi all,

Here is an other example that accept a term "uses" with masm procedure.

this masm code is Mr dedndave's code ,  topic : http://masm32.com/board/index.php?topic=1046.0

It looks interesting
What about source level debugging?
64 bit?

[Emil_halim]

It looks interesting

thanks , the interesting thing is that you can use high level asm with Masm code .

ie. instead of writing this

Code Select Expand


   mov al , byte ptr [esi]


you can do it like that

Code Select Expand


  al = char [ esi]


What about source level debugging?

I am afraid , there is no source level debug with c-- , instead you can use  ollydbg debuger.

64 bit?

note well ,the back end is c-- compiler ver 0239 2005 , so c-- will not produce 64 bit.

I so not know about 64bit , but c-- can produce an object file that can be linked with masm linker ,but can
obj32 file linked with 64 bit linker ?

hi all;

this time i have add c preprocessor  by using cpp exe of gcc.

so what it is good for ?

actually you can use define c macro with masm and c-- to make inline function style.

see this demo

enjoy coding masm % c--.

Hi all,

also added  Equ masm directive , so Ext_c-- will understand it.
