Matlab Coder: C code generated, how to compile?

Hi,

I have generated C code a single matlab function. I need to call this function from other C code.

Can anyone point me towards any information on writing a makefile for matlab codegen c code?

Thanks,

Further Details:

Linux, 64bit OS, using gcc.

After code generation i have a folder full of files centered around function.c

i want to call function(args) from a separate file main.c . How do i compile the codegen files into an object for later linking to my main.c ?

[Kaustubha Govind]

There should be a makefile generated along with the code. Why not add your main.c to the existing Makefile and continue to use that?

Kaustubha, Thanks for your reply. I believe there is a make file of the form 'function_rtw.mk'. I have added my 'main.c' to its 'USER_SRCS' arguments and have added an include statement to 'function.h' within 'main.c' however i am unable to compile the code with the command:

make function_rtw.mk

How does one use these make files?

As I wrote below, once you have a make file this becomes a Linux question rather than a MATLAB question. You would use the Linux resources for solving the problem, starting with

man make

In particular, read about -f

Once you have the C code generated, this becomes a C / Linux question rather than a MATLAB question.

You might want to use GNU automake

Hi! I dont have matlab coder; but I want to test it; Someone can help me to generate this matlab code in C for me ? Tanks for your helping.

MATLAB Coder cannot generate graphics, and it cannot "clear all"
