新手请教：编译内核的问题

morgin7

春节的时候开始研究这个，从网上搜集各种资料，gcc都以成功，到了最后了，开始make，在做make的时候，出现错误，不论make oldcomfig或者make menuconfig中怎么选择，都是一样的错误：

还请指教

你.config用错 或是你编译环境用错都有可能, 请检查

morgin7

哦，谢谢，新手，请指点怎么检查呢？

wayling

你gcc ,kernel, 怎么来的,版本是多少, gcc 跟kernl版本太多了 有些不兼容或需要做修改,
config你怎么设的,我看你是想编x64的kernel ?你去找正确的config来用八

morgin7

嗯：以下是版本号：

gcc-4.6.12.tar.bz2，gmp-4.3.2.tar.bz2，mpc-0.8.1.tar.gz，mpfr-2.4.2.tar.bz2

kenel：linux-2.6.1.tar.xz

下载的地址是百度搜索的
gcc：Index of ftp://gcc.gnu.org/pub/gcc/infrastructure/
内核：http://www.kernel.org/

我是想看看相关qla2xxxx的驱动编译

morgin7

下了一个linux kernel :linux-3.2.2.tar.bz2

make一切顺利，真的是版本问题吗？新版本的gcc对数据类型检查特别严格吗？

morgin7

我需要用linux-2.6.1的。请问都要修改什么呢？望指教

morgin7

版本：linux-2.6.32.56.tar.bz2

也可以正常编译，就2.61的出错～～～～

需要改什么地方呢？？请高手指教

morgin7

看来是过高的版本无法编译太低版本的。
