编译GCC-2.95.3

hillson

各位高手请帮忙:
      我在Fedora core 3 下编译gcc-2.95.3,配置为 ../configure --target=arm-linux --prefix=/home/.... --without-headers --enable-languages=c --disable-threads
并且执行过程也没问题,但是,MAKE时出现几条下面的错误:"no such instruction",百思不得其解,请各位高手请帮忙,多谢.

晨想

觉得问题是：--target=arm-linux

如果要cross的话，要有相应的kernel headers/glibc库/ld等。

（你要编译一个在本机运行的，为arm体系编译的gcc？）

hillson

是的,我为ARM编译GCC,请问我正确的步骤应该咋做?

请各帮忙分析一下!

正确步骤我不知道，不过你可以参考一下已有的脚本。

在gcc-2.95.3\INSTALL\configure.html 中有以下的说明,应该如何理解,"CC","GCC"是什么:
when configuring a native system, either "cc" or "gcc" must be in your path or you must set CC in your environment before running configure. Otherwise the configuration scripts may fail.

请各位帮帮忙吧!

晨想

CC和GCC 应该指向现有的 cc 和 gcc 命令。

比如
GCC="/usr/bin/gcc"
CC="/usr/bin/cc"
也可以扩展成

GCC="/usr/bin/i686-pc-linux-gnu-gcc"
CC="/usr/bin/i686-pc-linux-gnu-cc"
之类的。
