Building GCC-4.1.1 C/C++ compiler for LPC3180 + VFP + Embedded Linux

Hello,

I want to have a cross compiler running on my win32 cygwin, that can
cross compile C/C++ code for LPC3180 with VFP to run on embedded linux.


I downloaded gcc-4.1.1 source onto win32 cygwin (I dont even know if I
downloaded the right compiler source for the job), and started reading
the instructions on how to compile the compiler.  First it says you
have to configure the build, then build the compiler.

I'm not an expert and there are so many configuration parameters to
configure the build before building the actual compiler, that I know
will take me 100 years to figure out.

Does anybody have a clue on how to configure the build, then do the
build to build the gcc compiler that cross compiles C/C++ code for
LPC3180 with VFP for embedded linux.

Thanks
Over my head

Look for "buildroot" which is a mechanism to build cross
compilers, usually associated with ucLinux.

There is a "crosstools" script that could be useful as well.

Just curious, what hardware platform are you running on?  Do you have a
specific buildroot for that lpc part?
