Problem running C6000 Linker from the command line

DanaT

In order to test running the linker from the command line, I have successfully created a new project using the CCS IDE v 6.1.1.00022 (File->New->CCS Project) and would now like to run the linker CL6x.exe from the command line to link the object code generated by the compiler . I copied the linker command file generated by default c6748.cmd, to the debug directory and added one line to the .cmd file main.obj.

When I run the linker using Cl6x --run_linker c6748.cmd

I get "error: no input section is linked in"

if it bypass the cmd file and just run Cl6x --run_linker main.obj" I get the same error.

How can I use the IDE to generate the .obj files and then use the linker from the command line to successfully generate the same .out file as the IDE created. I thought I could just add the .obj file to the .cmd file but I am missing something.

The compiler makes the .obj file. You need to tell the compiler to compile main.c to get main.obj. Try this:
cl6x main.c --run_linker c6748.cmd

I was trying to run the Linker independent of the compiler. SPRU186W gives the example:
cl6x --run_linker file1.obj file2.obj
But that gives me the error I indicated

This works ...

DanaT said:
cl6x --run_linker file1.obj file2.obj

only for an all assembly code program. You are building a C program. So you need to tell the linker to use the conventions for linking C code.

cl6x --run_linker --rom_model file1.obj file2.obj

Read about the option --rom_model in the C6000 assembly tools manual.

Thanks and regards,
