Hello,

I have a weird problem using 'make'. When I try to compile using an
(automatically generated) makefile, I get some error messages like the
following:

----------------------------------------------------------------------------------------[vbc
ol=seagreen] 
cc -c <-- skipped -->  rtw_test.c
/tmp/ccrai8yi.s: Assembler messages:
/tmp/ccrai8yi.s:120: Error: suffix or operands invalid for `push'
/tmp/ccrai8yi.s:122: Error: suffix or operands invalid for `push'
/tmp/ccrai8yi.s:123: Error: suffix or operands invalid for `push'
----------------------------------------------------------------------------
-------------

However, when I copy the command "cc -c <-- skipped -->  rtw_test.c"
manually into a shell it works without errors!

Any ideas what's going on? I would be happy about any suggestions.
PS: I already tried to specify a different shell within the makefile
(using SHELL=/bin/bash, etc ...), but this did not solve the
problem.

regards,
christian

This is probably due to misconfiguration.  Environment variables (like
PATH) can be changed in a Makefile.

General makefile-debugging technique: take the part that says something like

bar.o: bar.c
cc -c bar.c

and change it to

bar.o: bar.c
@echo cc -c bar.c
@$(SHELL)

Now when you run make you will find yourself in an interactive shell
with the same environment the compiler runs in. Cut and paste the
compile line into this shell; it will fail. Debug it within the new
shell env.

Most likely it's confusion between two different versions of 'as'.

Dear Henry and Gianni,

Thank you very much! The difference was indeed the use of two
different versions of 'as'.

PS: The 'makefile-debugging technique' helped a lot!
