I’m not doing it wrong. Remember, this is a simplified example. We want to be able to make foo.cc so we can look at it and compare it. Yes, we could make foo and then look at foo.cc, but until foo.cc is right, we will suffer a lot of compiler error clutter. When foo.cc looks right, then we will make foo.
BTW, changing add_custom_command to add_custom_target has no apparent effect and doesn’t help. > On 2015-06-12, at 12:24 AM, Nagy-Egri Máté Ferenc <csiga.b...@aol.com> wrote: > > You’re doing it all wrong.
