下面是FC5下编译2.4.20的例子，FC5有bug，中文命名文件会没有反映，建议用稳定的FC4，FC5内核貌似2.6.15还是18忘了。 1.准备2.4.20的源代码 $tar jxf linux-2.4.20.tar.bz2 $mv linux-2.4.20 linux $cd linux $make mrproper $make config $make dep 上面这些步骤都能顺利 通过 $make bzImage 一会就出现了如下的 错误 /usr/linux-2.4.20/include/linux/smp.h:29: error: conflicting types for 'smp_send_reschedule' /usr/linux-2.4.20/include/asm/smp.h:42: error: previous declaration of 'smp_send_reschedule' was here In file included from /usr/linux-2.4.20/include/linux/unistd.h:9,from init/main.c:17: /usr/linux-2.4.20/include/asm/unistd.h:375: warning: conflicting types for built-in function '_exit' 这是因为FC5下的GCC版本太新（gcc4.1） 建议使用 gcc 2.95或者gcc3.2进行编译（Dave Thompson） 在网上寻找了一会，发现其实FC5下可以安装一个pachage，就可以使用gcc3.2，同时不会影响当前的gcc4.1。 于是就在 ftp://rpmfind.net/linux/fedora/core/5/i386/os/Fedora/RPMS/compat-gcc-32-3.2.3-55.fc5.i386.rpm 里下载了一个 该包的大致描述为：The compatibility GNU Compiler Collection Fedora Core 5 for i386，马上进行安装 $rpm -ivh compat-gcc-32-3.2.3-55.fc5.i386.rpm 安装完成后在/usr/bin下多了一个gcc32 于是马上修改Makefile，把里面的CC修改为 gcc32，接着 $make bzImage 经过漫长的等待（不长，也就15分钟左右），结果等来的却是： {standard input}: Assembler messages: {standard input}:936: Error: suffix or operands invalid for `mov' {standard input}:937: Error: suffix or operands invalid for `mov' {standard input}:1031: Error: suffix or operands invalid for `mov' {standard input}:1032: Error: suffix or operands invalid for `mov' {standard input}:1083: Error: suffix or operands invalid for `mov' {standard input}:1084: Error: suffix or operands invalid for `mov' {standard input}:1086: Error: suffix or operands invalid for `mov' {standard input}:1098: Error: suffix or operands invalid for `mov' 结论：是FC5下的binutils的一个bug， 下载相应的补丁 http://www./pub/linux/devel/binutils/linux-2.6-seg-5.patch 在待编译的内核源码（本例为linux-2.4.20/）的根目录下进行patch操作： $patch -p1 patching file arch/i386/kernel/process.c Hunk #1 succeeded at 693 with fuzz 1 (offset 96 lines). patching file arch/i386/kernel/vm86.c Hunk #1 FAILED at 294. 1 out of 1 hunk FAILED -- saving rejects to file arch/i386/kernel/vm86.c.rej patching file arch/x86_64/kernel/process.c Hunk #1 succeeded at 458 with fuzz 2 (offset 67 lines).

Hunk #2 FAILED at 96. 1 out of 2 hunks FAILED -- saving rejects to file include/asm-i386/system.h.rej $make bzImage 又是漫长的等待，出现如下错误 {standard input}: Assembler messages: {standard input}:936: Error: suffix or operands invalid for `mov' {standard input}:937: Error: suffix or operands invalid for `mov' {standard input}:1031: Error: suffix or operands invalid for `mov' {standard input}:1032: Error: suffix or operands invalid for `mov' make[1]: *** [process.o] 错误 1 make[1]: Leaving directory `/usr/src/linux/arch/i386/kernel' make: *** [_dir_arch/i386/kernel] 错误 2 是as的问题，再编辑 arch/i386/kernel/process.c 在579行，将 asm volatile("movl %%" #seg ",%0":"=m" (*(int *)&(value))) 改成 asm volatile("mov %%" #seg ",%0":"=m" (value)) 执行 $make bzImage 一切正常 $make modules $make modules_install 出现了如下的信息 cd /lib/modules/2.4.20; \ mkdir -p pcmcia; \ find kernel -path '*/pcmcia/*' -name '*.o' | xargs -i -r ln -sf ../{} pcmcia if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.4.20; fi Version requires old depmod, but couldn't run /sbin/depmod.old: No such file or directory make: *** [_modinst_post] 错误 2 那就创建一个depmod.old的链接 $ln -s /sbin/depmod /sbin/depmod.old $make modules_install $mkinitrd -f -v /boot/initrd-2.4.20.img 2.4.20 一切正常，修改相应的 lino或者 grub，重新启动。 如果你不是用FC5，再遇到错误贴出来我给你看。。。。 |
