GNU Arm Embedded Toolchain

Problem with @FILE param at GCC compiler

Asked by Vinicius

When I use GCC compiler at command line it's ok at MAC or Windows
But when I use a @FILE at Eclipse environment just creating a example project, and after that include a additional file in Miscellaneous parameters with @"/home/project/compiler.via" for example in MAC OS it does not work, but if I include all parameters directly outside of file, it works well.
Doing the same thing with same version of eclipse at Windows it works perfectly.

It seems to be a bug at gcc parameters or with eclipse plugin.

The same concept at linker works well in all versions.

I am using eclipse kleper, just download the GNUARM plugin, and the actual version 2014p2 from GCC launchpad.

Best regards,
Vinicius

Does this @FILE work for a normal x86-based native project on Mac?

I might do something wrong, but I couldn't reproduce this issue with Kepler on Mac. Here are steps I tried:

1). Create a file named compiler-option with one line "-da" which is a gcc option to dump all results during the compilation.
2). Add option "@/Users/build/compiler-option" to "Expert settings: Command" field in "Tool Settings" tab.
3). Rebuild the project.
4). I can see all the expected dump files which means the @FILE works for GCC.

Here are my screen paste from Eclipse Console:

Hi Terry,

In expert configuration for some reason it's working well.
The project that it's working in windows the same parameter it's in miscellaneous "other compiler flags"

But it's working in expert place, so thank you again.
If you can check why it's working in other compiler flags at windows and not in mac, it's nice to understand.

Best regards,
Vinicius

This time I put it into "Other compiler flags" in "Miscellaneous" of "Cross ARM C Compiler" in "Tool Settings" tab. Then rebuild the project, it works fine. The only difference is the position of @FILE in command line. If this doesn't work for you, would you please check the output in Eclipse Console? Maybe you missed a space after @FILE command? Here is my screen paste again:

If you can paste one of your compiler output here, that will be helpful for diagnose.
