Compiler/LAUNCHCC3220MODASF: Using a Makefile with CCS and assembly files

Charles Fleck1
Intellectual 650 points

Part Number: LAUNCHCC3220MODASF

Tool/software: TI C/C++ Compiler

Hey guys,

I'm currently trying to compile some code using Code Composer Studio and a Makefile. It's currently working fine with .c and .cpp files, but I'm trying to include the PowerCC32XX_asm.asm file in the makefile and I've been having issues. I assume the tool I want to use to compile assembly files is armcl.exe? Or do I want to use armar.exe or armasm.exe? Also, what is the format for compiling using any of these. I've been using gcc and g++ for the c and c++ files, so I don't have much experience with these executables yet.

Thank you in advance!

Charles

    Are you using those precise names for the compiler?  Those tools don't build code for the ARM CPU in your system, but for your host system (a laptop, or something similar).  Use the GCC ARM compiler named arm-none-eabi-g++.  It uses the file extension to know how to build a source file.  The file extension .c means C, .cpp means C++, and .s means assembly.  Lots of other extensions are recognized, but these are the usual ones.

    Charles Fleck1 said:

    That's the TI ARM compiler.  Use either the GCC ARM compiler, or the TI ARM compiler.  Not both in the same project.  Not because it impossible to mix these compilers.  Just because, as a practical matter, it is hard to organize a project that uses more than one compiler.

    All that said, it is practical for one ARM compiler to link in a library that is built using the other ARM compiler.

    Thanks and regards,

    -George

    Hey George,

    We are currently using arm-eabi-gcc for .c files and arm-eabi-g++ for .cpp files. The TI assembly files have an extension .asm, not .s, and it doesn't seem like any of the arm-eabi compilers are able to compile them. I would prefer not to rewrite our entier Makefile to use the TI ARM compiler, is it possible to use the GCC ARM compiler to compile .asm files?

    I did try using the armasm.exe compiler, but it is giving me a bunch of assembly errors that I've pasted at the end of this message.

    Thanks again!

    Charles

    You can simplify that.  Just use arm-eabi-g++ for both C files and C++ files.  

    I don't recognize those names.  You must be using a GCC ARM compiler that is not released by TI.  Strictly speaking, this forum only supports compilers released by TI.  However, it is a good guess all GCC ARM compilers have the same interface, so my answers are probably correct.

    Charles Fleck1 said:

    Apparently, you don't want to rename the files from .asm to .s . So, yes.  When building a .asm file, add this option: -x assembler

    Charles Fleck1 said:

    There are differences in assembly syntax between the GCC ARM tools and TI ARM tools.  The instructions are the same.  But the assembler directives are different.  It is likely your assembly files use the directives expected by the GCC ARM tools.

    Thanks and regards,

    Hey George,

    I have confirmed that I can use arm-eabi-g++ to compile both .c and .cpp files, but I'm still having trouble with the assembly file. I tried arm-eabi-g++ -x assembler PowerCC32XX_asm.asm, but it spit out a bunch of errors. It looks like it's trying to compile a .s file, not a .asm file, as it doesn't recognize ; as a comment. I confirmed this by changing ; to @ and it then recognizes them as comments. I've attached the errors to the bottoms of this message.

    Thanks!

    Charles

    This file PowerCC32XX_asm.asm has been rejected by the TI ARM assembler and the GCC ARM assembler.  You need to get with whoever supplies that file.  Ask them which assembler and build options to use.

    Thanks and regards,

    Hey George,

    The PowerCC32XX_asm.asm file actually is a TI file. It is part of the Simplelink library that you guys make, which is why I assumed I should be able to compile it with the TI compiler somehow. It's used in the power management example you guys have. Do you have any hints on how you guys compile this file in that example? I tried checking the compiler output and it looks like it may be being built as part of one of your libraries. Am I supposed to build the Simplelink library using my Makefile? And if so, how do I do that?

    Edit: I have discovered that the arm-eabi-g++ -x assembler -mcpu=cortex-m4 -mfloat-abi=soft PowerCC32XX_asm.sm4g does a lot better at compiling, so I think the .sm4g file may be the correct one to use for g++. The issues it has now are with some variables that are defined in a .c file.

    I think either being able to compile the library or being able to get the .sm4g file compiling with g++ should resolve my issue, so any help with either of those would be apprecitated.

    Thank you!

    Charles

    Hey George,

    I got it figured out. The PowerCC32XX_asm.sm4g file actually contains the same assembler code as PowerCC32XX_asm.asm, but it's formatted for arm-eabi-g++ (and I assume arm-eabi-gcc as well, but I didn't test this). To compile the file you just need to do:

    arm-eabi-g++ -c -x assembler -mcpu=cortex-m4 -mfloat-abi=soft PowerCC32XX_asm.sm4g

    Thanks for the help!
