I am trying to recover a project that I was forced to put on the back burner a few years ago when the M68HC12 was current. I have $1000 invested in prototypes, so don't want to start over with a new chip since it is a proof of concept project.
Trying to download a copy of m6811-elf-gcc for new dev laptop is OK but binutils patches for the 68HC11 web site 404's and nowhere else to be found, so I just copied binaries from backup of prior dev laptop.
I am running SuSE linux LEAP 15.0. gcc 7.4.1 and as 2.31.1.20180828-lp150.5.3.
I kept getting 'as: unrecognized option '-m68hc12'' so I copied m6811-elf-as from backup and put it in path. I still get the same error from as.
Decoding the output of make, I can see it is calling the m6811 version of as:
make -n gives (in part) ... m6811-elf-as -o mcx12.o -m68hc12 -mshort mcxif.s system.s mcx.s clkdrivr.s scidrv.s atddrivr.s main2mcx.s vectors.s ...
but when I manually type in the exact same line that make is saying it generates, it works perfectly on the previously cc'ed source code without the 'as: unrecognized option '-m68hc12' ' error.
So make is saying that it is executing that line and gets errors, but the line itself does not when entered manually.
Any ideas?
any help very appreciated!

update Oct 15: I agree with what you say, but I cannot see how it can output m6811-elf-gcc with the -n option and really be calling as!
here is the output of make:

OK, added that to makefile, and now makefile says:

I will explore those non-existent directories and see what happens if I copy them from backup :-)
