Command line length out of control with large tree giving lots of -I paths. about mbed-cli HOT 6 CLOSED

That can be fixed with "reponse files":

• put all your options in a file (options.txt for example)
• instead of doing gcc -opt1 -opt2 ..., do gcc @options.txt). ld supports this too.

armcc has similar support with the --via option. I think armlink also supports this.

No idea if IAR supports it.

Additional caveat: if this is done, in case of a compiler error, one needs to cat the content of options.txt to stdout manually (I think). Also, if we do this, compiling in verbose mode (neo compile -v) doesn't have a lot of meaning anymore.

@bogdanm Thanks for the hint. This is for the build system.
@mjs-arm Can you help me reproduce the issue? e.g. repository to clone etc

I've personally not hit it, try building the demo on windows. I believe @c1728p9 has definitely hit the issue somewhere....

From my experience, it's quite difficult to reproduce this issue on different Windows installations (even if all of them are Windows 7) across different computers. But it definitely happens.

This is now implemented in the latest tools in https://github.com/ARMmbed/mbed-os
