Hi Richard, I have downloaded the docs and am having a browse now, thanks. I did export the projects build file and searched it for "abi" but only found "-mfloat-abi=soft" which specifies an ABI for floating point values. There is a GCC option "-mabi=name" but that does not appear anywhere in my command lines. Given that the -mabi option is not present presumably I am using a default ABI, but what is it? Is there a way to get GCC to display all of its default options that it uses when for example certain comman line options are not specified?
