CCS: Makefile -WI, -MMD, -MF option

Sunny Kang said:

But GNU linker does not support -WI option in Makefile.

Could you please elaborate on what you mean by this?

The -Wl option is used to pass linker options to the compiler driver (gcc). Since the build command in CCS invokes gcc rather than the linker directly, the linker options should be passed using the -Wl option. I'm wondering why you are looking to eliminate the option.

Where and how are these options set? If they were set via the GUI project settings in CCS, you should be able to remove them also from there.
But perhaps I do not understand your question correctly, and if so, could you please clarify?

Thanks a lot for your reply.

1. on "GNU linker does not support -WI option."
- I used "Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-gcc.exe" and "Sourcery_G++_Lite/bin/arm-none-linux-gnueabi-ld.exe"
- I build on Release.

- CCS v7 made Release\makefile as follows,

- I cannot find -MMD, -MF, -MT option in "arm-none-linux-gnueabi-gcc.exe --help"

Please help me how I cannot select above 4 options as soon as possile.

Thank you in advance.

Best regards.

OK, so you are using the Code Sourcery tools and not the Linaro GNU compiler tools included with CCS?

Is this an Eclipse C/C++ project or CCS project?

If the tool invocation is changed from arm-none-linux-gnueabi-ld.exe to arm-none-linux-gnueabi-gcc.exe then the -Wl option will be valid and there should be no error. You should be able to change the executable that gets called (ld to gcc) from the Project Properties, Linker settings.

How did these options get added to begin with? I imagine you should be able to remove them from Project Properties, Compiler settings but I cannot tell for certain without looking at how the options are set in the GUI.
