Create a crosstoll cross-compiling environment

Objective: To compile other instruction sets on an existing machine, for example, to compile MIPS and PPC on x86.

Body:

1. Obtain the crosstool toolkit and decompress it.

2, choose a suitable template, such as powerpc-405-linux-gnu,
This article selects the demo-ppc405.sh template.

A) vi
Demo-ppc405.sh

The red part is the source code directory, the tool directory, the language, and the corresponding version file.

B) Vim powerpc-7450.dat.

TARGET=powerpc-405-linux-gnuTARGET_CFLAGS="-O -mcpu=405"GCC_EXTRA_CONFIG="--with-cpu=405 --enable-cxx-flags=-mcpu=405"GLIBC_EXTRA_CONFIG="$GLIBC_EXTRA_CONFIG --without-fp"

Tool chain name in red

C) Vim gcc-3.4.1-glibc-2.3.3.dat.

The corresponding directory is the source code package file

D)./demo-ppc405.sh.
