Linking error- LNK2001

[praveen_sup]

Hi ,

I have written program in 'c' and 'ada' . 'c' program call function existing in ada. I have compiled 'c' program in 'c' compiler and 'ada' program in ada compiler. I have gernerated obj of both 'c' and 'ada' programs. Now I want link together and generate dll. While compilation I am not having any problem but while linking I am getting link error - LNK 2001.
I am compiling these two programs on command prompt.
Please suggest me some solution.

Here are commands I am using compilation:
----------------------------------------------------
'c' program compilation command :
cl -c MY_DLL.c

'ada' program compilation command:
adacomp -gc -asm adacode.ada

Here is Linking command I am using for linking above two objs
------------------------------------------------------------------------------
link MY_DLL.obj adacode.obj /NODEFAULTLIB:libcmt.lib -dll


I am getting following linking error:
--------------------------------------------

>link MY_DLL.obj adacode.obj /NODEFAULTLIB:libcmt.lib -dll

Please help in solving these linking errors.

For your reference I am attaching my files.

I am waiting for reply.

I have never programmed in ada and I have never linked with an
ada module, however it looks like your errors are referring to
generic ada stuff. By that, I mean the function names look similar
to what you'd find in standard C. If there's an "ada C-runtime
library" or something like that, I think you should link with that.
It looks like your ada module requires your C programs to link
with that module and an additional library, but I could be wrong
having no ada experience whatsoever.
