本来已经在Linux下有一个eldk的编译器了.但由于PC经常工作在XP下,所以就在XP下安装了一个虚拟Linux环境的CygWin,想在cygwin上搭建PowerPC交叉编译环境(主要针对MPC875).
哪位有这方面的成功经验的?
在网上看到一篇这方面的**,照着做没成功,主要是**里混进了一大堆E文,分不清哪些是必须要做的步骤了,汗.**内容如下:
使用GNU编译器.
GNU编译器是免费的编译器. 而且是交叉编译器. 支持mips arm, ppc, M680.
Cygwin是一种linux仿真器, 可以使GNU在windows2000下运行.
有了这俩个, 应该, 不需要买什么编译器了.

我是用他来编译PPC的程序的.
安装步骤如下. 不过我用的是GCC-3.0.3版.
编译GCC我的机器是900Mhz PIII cpu 256M memory.
大约是3个小时.
如果, 你不是特别一定要用的话, 那可别玩.
(以下是从网上拷贝的).
Building a gcc crosscompiler for powerpc on win32
get cygwin, and source for binutils-2.10 gcc-2.95.2-core, gcc-2.85.2, newlib-1.82
Install cygwin [add instructions here]
run cygwin. you"ll get a bash prompt (...oh my god it"s unix!)
make a folder to do all the work in and cd to it
(e.g. mkdir /cygdrive/d/gcc-win32, cd /cygdrive/d/gcc-win32 - this translates to d:/gcc-win32 in MS land)
unzip binutils and gcc-core and gcc and newlib into there
make a build directory (build-win32, say)
mkdir build-win32/binutils
cd build-win32/binutils
../../binutils-2.10/configure --prefix=/usr/target-powerpc --target=powerpc-unknown-eabi
make
make install
以上是生成powerpc的汇编编译器.
export PATH=/usr/target-powerpc/bin:$PATH
cd ..
mkdir gcc-core
cd gcc-core
../../gcc-2.95.2-core/configure --prefix=/usr/target-powerpc --target=powerpc-unknown-eabi --with-exeext=".exe" --with-newlib
make
make install
只有编译core. 如果现在就编译全部GCC的会, 会出错, 我的个人经验.
for some reason the build produces a gcc spec file with CR/LF"s rather than LF Line endings, so convert the line endings on
/usr/target-powerpc/lib/gcc-lib/powerpc-unknown-eabi/2.95.2/spec
[ NOTE:
(if you dont have a suitable tool use the following shell script - create a file called dos2unix with this in and stick it in your /usr/local/bin)
#!/bin/sh
cat $1 ¦ sed "s/^M{1,}$//" ¦ sed "$ s/^Z//" > $2
]
以上, 如果你mount disk的模式为bin mode的话, 不会出现.
----- these following stages are only useful if you want a standard c library or c++/java/chill ----
compile newlib
cd ..
mkdir newlib
../../newlib-1.82/configure --prefix=/usr/target-powerpc/ --target=powerpc-
unknown-eabi
make
make install
and finally build a full gcc
cd ..
mkdir gcc
cd gcc
../../gcc-2.95.2/configure --prefix=/usr/target-powerpc --target=powerpc-unknown-eabi --with-exeext=".exe" --with-newlib
make
make install
