compile error with gcc 4.3
Friedemann Bunjes
i have problems compiling the current comedy version using a current autimake and gcc 4.3:
…
gcc: 0: No such file or directory
gcc: unrecognized option '-G'
…
autogen, configure and compile logs: see below.
Thanks in advance for any help!
Best,
Friedemann

yes, same messages after symlinking /usr/bin/gcc-4.4 to /usr/bin/gcc.
Best,

There's no need to symlink gcc (and it may screw other things up!). You
can override it by setting LINUX_CC when running 'make', e.g.:
make LINUX_CC=gcc-4.4
Whatever you do, the comedi modules (and rtai modules) need to be built
with a similar version of gcc as the kernel so the first two components
of the version number (major and minor version) have to match. E.g. if
the kernel was built with gcc 4.3.2, the modules can be built with 4.3.4
(matches 4.3) but not with 4.4.0 (does not match 4.3).
You can find out which version of gcc the kernel was built with with
cat /proc/version
Note that the usual method of overriding the CC version when invoking
configure (e.g.: CC=gcc-4.4 ./configure) is ineffective because the
comedi configure script effectively asks the kernel Makefile what
compiler to use and sticks it in LINUX_CC.
I think it would be better if the comedi configure script had an option
to configure LINUX_CC manually, overriding the auto-detected value.
Then you could specify it once at configure time and wouldn't need to
specify it on the make command-line every time. I'll have a look into that.
In the meantime, check /proc/version to find out which compiler to use,
and set LINUX_CC=(something) when you run 'make' as shown above.
Best regards,
Ian.

thank you very much for the hints.
Weird: Although considering the approach you suggest, the problem persists:

The other thing to consider is that the compiler flags aren't set by
comedi, they are set by the kernel, and different architectures use
different flags. Strangely, the only architecture I can see in the
kernel that uses that combination of CFLAGS is the MIPS architecture!
If you're picking up flags from the kernel's arch/mips/Makefile, there
must be something strange about your kernel .config!
