Passing additional enviroment variables to amu for use in MakeFiles

I am looking to rebuild my hacked-about version of DeskLib on new hardware. While I rolled my own 32 bit conversion and compiled it with an old toolset on a RiscPC, there are big problems with the build process with all-new kit because the tools run in a 26 bit world.

This was not difficult. I removed the arcane and freaky pile of scripts and assorted programs and just replaced it with a short BASIC program that goes through and deletes all the o.* files, and then generates a big TaskObey file calling AMU for each MakeFile found. I am surprised the DeskLib guys didn’t think to do that in the first place!

The reason for this post. I don’t fancy patching all of the MakeFiles to specify a (26/)32 bit world. Though, I don’t think I have to, for the macros in each are like this:

CCFlags  = -ffahi $(CCExtra) -depend !Depend -throwback -D_DeskLib_$(LibName) -I,C:
ASMFlags = -Stamp -NoCache -CloseExec -Quit $(ASMExtra)

The important part is $(CCExtra) and $(ASMExtra) which are not defined. I suspect this is to allow extra flags/options to be added externally in preference to modifying every single MakeFile.

The commands I generate are:

amu -desktop -f <makefile path here>

What would I need to add to this line to define CCExtra as “-apcs 3/32 -Wxxx -exxx”, and ASMExtra as “—throwback —32”?

I do not see any h commandline flag in the Acorn DDE manual.

amu variable=value

see amu -h

What would I need to add to this line to define CCExtra as “-apcs 3/32 -Wxxx -exxx”, and ASMExtra as “—throwback —32”?

It’s as simple as:

amu -desktop -f <makefile path here> CCExtra="-apcs 3/32 -Wxxx -exxx" ASMExtra="-throwback -32"

CCExtra="-apcs ...

That’s it? Just define it on the command line? Whoo. So simple! ;-)
Thanks.
