Creating Static Library and Linking

[acobulareddy]

I am using Intel Fortran 9.1 and VC++ 2005.

I have two programs

PROGRAM main
write(*,*)"Calling C Function"
CALL ChgStr()
write(*,*)"Back From C Function"
END PROGRAM main

#include
#include
void chgstr()
{
printf("\nIn C function");
}

I would like to create a static library of C program and use it for fortran executable.

Please suggest how to do it.

I did the following.

cl -c chgstr.c
created a object file chgstr.obj

lib /out:clib.lib chgstr.obj
created static library for chgstr.obj

ifort /names:lowercase /extend_source -c fmain.f
created fmain.obj

ifort fmain.obj clib.lib
(to create executable of fmain.obj clib.lib but gave following error)
Intel Fortran Compiler for Intel EM64T-based applications, Version 9.1 Build 20070109
Copyright (C) 1985-2007 Intel Corporation. All rights reserved.

Fatal error cannot open "ifconsol"
ifort: error: problem during multi-file optimization compilation (code 1)

tried with the link command
link /out:1.exe fmain.obj clib.lib
gave the following error
Microsoft Incremental Linker Version 8.00.50727.42

LINK : fatal error LNK1104: cannot open file 'ifconsol.lib'

Please suggest how to do.

Is there a way I can do it through IDE (VS2005)

Thanks,
Chandra

When I did this recently (all through the IDE), I just added the lib to my fortran project.

I suggest adding the path of the ifconsol library to the link command.

May I know the procedure you have followed to add it through IDE.

What is the version of VS you have. I have VS2005, Does it have the capability

tried the folliowing

C:Documents and Settings105032692DesktopDesktopc-fortran1>link /out:1.exe fmain.obj clib.lib "C:Program FilesIntelCompilerFortran9.1ItaniumLibifconsol.lib"

LINK : fatal error LNK1561: entry point must be defined

still it is not working.

In your original post you indicated that you were using the EM64T compiler but here I see you referencing Itanium libraries. These are not the same! What kind of system are you building for?

I recommend using the ifort command to link.

[acobulareddy]

even I tried with IA32 and got the same error

C:Documents and Settings105032692DesktopDesktopc-fortran1>link /out:1.exe fmain.obj clib.lib "C:Program FilesIntelCompilerFortran

LINK : fatal error LNK1561: entry point must be defined

I am more interested with link because VS uses LINK command to create executable (VS uses ifort only for creating objects)

even I tried with ifort O gpt the following errors

I tried by changing the case of CHGSTR in C function. that is also not eliminating the unresolved symbol CHGSTR referenced in function main.

It would help if I could see all the commands used to build this application. There's something wrong in either the environment or an inconsistency in the build commands but I am not seeing everything. Part of the problem is that there is nothing supplying the main entry point (which is typically in a C run-time library. I am also puzzled by the routine names shown in the linker errors as it looks as if they are EM64T references. You cannot mix architectures - you must be consistent in the tools you use.

You are getting the error with ifconsol.lib because you might be trying to link in the normal command prompt window.

Try to do the link in the Intel IA-32 command prompt.
