Re: [Simulavr-devel] OSX compilation

[Jakob Schwendner]

Bill,

I have checked the config.h and indeed it has WORDS_BIGENDIAN 1 set.
Sorry it took me a while to test all this, but I updated to OSX 10.4
and that included a bit of work, to get all the dev environment back
up.
I send you a new patch as well, as I think a few things have changed
in 10.4 (gcc 4.0 to start with).

to get simulavr working I installed a copy of DarwinPorts and
installed the following modules:
port install -k avr-binutils (keep the build files as they are needed)
port install avr-gcc (I changed the Portfile to not use the version
suffix on binaries)

get the simulavr cvs
apply the darwin-patch.1.diff
./configure address@hidden/work/build
address@hidden/include

let me know if you need to know anything about the patch. I really
don't know very much about that autoconf and libtool stuff, so I had
to fight my way through, and hope its not too dirty.

cheers,

Jakob
