I have a basic question that I can't seem to find the answer to on the internet. I am under the impression that gcc ONLY compiles for the host system you have installed gcc on (by default gcc installations on linux machines). To compile gcc for a different processor you need to cross compile gcc for the particular target (in my case m68k). How come I can still specify -m68030 on my i386 system? I would expect compilation to fail, but it doesn't. Did it really compile for the i386 processor or the m68k? (I can't tell since it's supposed to run on the m68k - but I have other problems so I can't run it just yet). My confusion is the fact that it *looks* like I can compile for the m68k processor on my default gcc installation (Suse 9.1). I *think* I instead have to set up a full cross compiler tool chain. Note the program I am attempting to compile is a small program meant to be run on a Motorola mvme147 PowerPC. I also do not understand the -b option from the gcc man page. How does gcc know to use a different gcc compiler installed somewhere else. Also, I have a gcc binary file on a Sun machine (where the original code was created). Is there a way to get the original configuration that it was built with? For example, what it was configured to be cross compiled with (host and target system). The gcc binary was simply re-created and I can't recreate the full installation. Sorry for the basic questions, but I need to fully understand this before continuing... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
