gcc for PowerPc

gcc for PowerPc

[kaushik mondal]

Can we configure gcc so that it generates object files
in COFF format ?
What is the 'target' name for such a configuration?
Regards,
Kaushik

If you are using the -mcpu=powerpc with the same GCC image 
that is used to build i386 apps, then the error is expected.
You might choose to use that option with GCC built for powerpc.

I can use gcc compile for Intel and AMD cpu by specifying the switch "-mcpu=pentium4", but can't get powerPC work. if I set the switch to "-mcpu=powerpc", I always get the error message "cc1: error:had value <powerpc> for -mcpu switch". Could you help me and provide some advice if any. Thanks.

   Hi Dan, 

 Someone may have already answered this for you, but I couldn't find it,
so I may be repeating what you've already been told. The problem is that
gcc needs the header files for the target you're compiling for, and those
are the ones it's looking for at this stage. It's building libgcc2.a,
which contains support functions for the compiled code, so it has to be
compiled to run on the target, and therefore it needs the target headers.

 If you've got a real target system running some rtos, you should place
the header files from it into $prefix/$target/sys-include before you
start the build, or use the option --with-headers=/path/to/header/files
when configuring. If you don't have a target system running, you should
get newlib and use the headers from that.

Get newlib.

Re: gcc for PowerPC

Hi,

Because it is an CrossCompiler i advise you too use another prefix (the
default is /usr/)  e.g --prefix=/powerpc

First you will have to compile and install  glibc. With the same prefix
(powerpc) and then de binutils (with the same prefix) and the same goes voor
gcc. See also the CrossFAQ.

Kind regards,

It seems like the include path is not updated.
what should it contain ?

Thank you.

Hi,
can gcc be configured for PowerPc processors such that
it generates the object files in COFF format?
What is the 'target' name for such a configuration?
