Hash sign in a make file

is there a way to echo a # in a make file. I want to do:

echo #include "test.h" { > somefile.h }

The problem is the #sign is seen as a comment.

Not at a computer (and I use Amu because Make annoys me), but have you tried wrapping the string in single quotes?

I always think of amu as make.

Yes I’ve tried single quotes. I’ve tried / \ | % # before the #

Okay, I’ve read through the relevant parts of the Desktop Tools guide (actual dead trees, not some crappy PDF, whee! :-) ) and it doesn’t look like Make/AMU supports any form of escaping other than $$ and maybe a double (back?)slash. As it isn’t open source, one can’t rummage to confirm.

Nothing I tried works.

So, time to not so much think outside the box as to simply deny there is any box…

   echo <35>include "test.h" { > h.somefile }

Notice that the final filename is back to front. This is because the secret to how this works is that the echo line is simply passed on through to the RISC OS shell. So there’s no fudging to make file.ext style names the right way around. You must give it in a form RISC OS understands.

Your trace window, as you run Amu, will happily quote that line verbatim.
However if you look in the newly created “something” file, the shell has GSTrans’d it into the desired hash character.

You’re welcome.

Worked a treat.

Unfortunately the redirection has CRLF line endings and the compiler throws warnings which I don’t want.

When I’ve wanted to dynamically make something like that, I wrote a little BASIC program, and just had the MakeFile run it…

It’s worse than that – the endings are LFCR.
