Hi,
We are using the IAR toolchain for cross-compiling parts of our builds
and encountered a problem when we recently enabled response files for
our Windows builds. It seems that the syntax used for the response file
flags on the IAR compilers is wrong, we needed to insert a space after
the '-f' to make it work.
I attached a patch that fixes the problem in our environment.
We are building with the 'Unix Makefiles' generator from a Cygwin shell
in Windows. Can someone confirm that this is a proper fix for our issues
and whether it would make sense to have the patch merged into the CMake
trunk?
Thanks & best regards,
Andreas
