compiling and linking C/C++ user subroutine

[Antonio Lorenzo Mendicino]

Dear all

I want run an abaqus simulation with a user subroutine written in C/C++.
I have downloaded one from abaqus online support system answer 737.

I don't know how can I do this so I tried as it follows and I get:


C:\Documents and Settings\alorenzom\Documenti\HC3FEM\AbaqusUSrI>abaqus make libr
ary=visco.c
ABAQUS Error: The following file(s) could not be located: visco.c.for
ABAQUS requires an appropriate input file(s) to compile the user routine.
The ABAQUS Make execution procedure exited with errors

I know that in abaqus environment file there is compile_cpp parameter which contains c++ compile command.It appears like this

compile_cpp=['cl', '/c', '/nologo', '/W0', '/MD',
'/TP', '/GX', '/DNDEBUG', '/DWIN32', '/DTP_IP', '/D_CONSOLE',
'/DNTI', '/DFLT_LIC', '/DOL_DOC', '/D__LIB__', '/DHKS_NT',
'/DFAR=', '/D_WINDOWS', '/O1', '/I%I']


and I don't know how I can use this information.

If it could be useful:I work on windows/x86-32.I have installed intel fortran compiler9.1,ms vc++7.1,ms platform sdk 2003.I run an abaqus analysis with a fortran user subroutine successfully.

Has any one got any suggestions for me?

Thanks a lot in advance.

Hi Antonio,

C:\Documents and
Settings\alorenzom\Documenti\HC3FEM\AbaqusUSrI>abaqus make
library=visco.c
visco.c.for ABAQUS requires an appropriate input file(s) to compile
the user routine. The ABAQUS Make execution procedure exited with
errors

Note that ABAQUS "understood" that you were trying to compile a
fortran file (visco.c.for), which is evidently wrong. Try the
following: compile the visco.c file into visco.obj with the command
line version of the C compiler. Then run abaqus job=xxx obj=visco.obj

This has the additional advantage that you can keep the object file,
which will save you a couple of minutes from the compilation --only
the linking phase will be carried out-- if you submit the analysis
often (note that you need to recompile after each modification to the
source file!).

Hope this helps,
Fernando

Both compilers agree to complain at line 107 of your source file,
which is a very clear hint. I would say that you don't have the
"#include<string>" line, or else that you are missing a "use namespace
std" (in order to be able to address "string" as such, instead of
"std::string".

Hope this helps,
Fernando

I modified my extension file from .c to .cpp and I add it to an
empty .net project in Ms Development Environment 2003.
I compiled it successfully.

I try to run my abaqus procedure and I get

Perhaps I should pay attention for something in link_sl parameter in
abaqus env file?

I solve my problem.Thank you to all and special thanks to fcn_public.

Do you still remember how you solved it? I could not think of other
alternatives than what I proposed, other than "play around" --which I
thought you were already doing.

I'm quite sure many users will apreciate your first-hand report :-)

I compile successfully my c file with Ms Development Environment 2003, adding it to a project (named only_for_compile_an_existing_unit) and modifying some project properties, but I can't find corresponding object file.I expected it in Debug folder but it isn't there.

Here is the message I get in IDE:

------ Build started: Project: only_for_compile_an_existing_unit, Configuration: Debug Win32 ------

Compiling...

Build log was saved at "file://c:\Documents and Settings\alorenzom\Documenti\Hc3fem\AbaqusUSrI\only_for_compile_an_existing_unit\Debug\BuildLog.htm"
only_for_compile_an_existing_unit - 0 error(s), 0 warning(s)
