为旧内核设置buildroot [英] Setup buildroot for old kernels

问题描述

我试图安装的buildroot为交叉编译自定义应用.

I'm trying to setup buildroot for cross-compiling a custom app.

/ # uname -a
Linux Venus 2.6.12.6-VENUS #323634 Wed May 25 13:40:36 CST 2011 mips unknown

到目前为止，我在buildroot中选择了内核版本 2.6.12.6 .现在，我已经得到了问题的命令失败大呼小叫，该规则是未知的.

So far I chose kernel version 2.6.12.6 in buildroot. Now I've got the problem that the make command fails yelling that the rule headers_install is unknown.

以下是完整的输出:

~/buildroot-2011.11$ make
(cd /root/buildroot-2011.11/output/toolchain/linux-2.6.12.6; \
         /usr/bin/make -j2 ARCH=mips \
                HOSTCC="/usr/bin/gcc" HOSTCFLAGS="" \
                HOSTCXX="/usr/bin/g++" \
                INSTALL_HDR_PATH=/root/buildroot-2011.11/output/toolchain/linux headers_install; \
        )
make[1]: Entering directory `/root/buildroot-2011.11/output/toolchain/linux-2.6.12.6'
Makefile:485: .config: Datei oder Verzeichnis nicht gefunden
make[1]: *** Keine Regel, um »headers_install« zu erstellen.  Schluss.
make[1]: Leaving directory `/root/buildroot-2011.11/output/toolchain/linux-2.6.12.6'
make: *** [/root/buildroot-2011.11/output/toolchain/linux/.configured] Fehler 2

我认为问题在于此旧内核的makefile中没有此选项.

I think the problem is that this old kernel doesn't have this option in its makefile.

我的下一个尝试是通过替换旧内核，使用新内核3.2.6的Makefile和scripts目录.

My next try was to use the Makefile and the scripts directory of the new kernel 3.2.6 by replacing the old one.

下面是输出:

# make
(cd /root/buildroot-2011.11/output/toolchain/linux-2.6.12.6; \
         /usr/bin/make -j2 ARCH=mips \
                HOSTCC="/usr/bin/gcc" HOSTCFLAGS="" \
                HOSTCXX="/usr/bin/g++" \
                INSTALL_HDR_PATH=/root/buildroot-2011.11/output/toolchain/linux headers_install; \
        )
make[1]: Entering directory `/root/buildroot-2011.11/output/toolchain/linux-2.6.12.6'
  CHK     include/linux/version.h
  HOSTCC  scripts/basic/fixdep
  HOSTCC  scripts/unifdef
Makefile:1059: *** Headers not exportable for the mips architecture.  Schluss.
make[1]: Leaving directory `/root/buildroot-2011.11/output/toolchain/linux-2.6.12.6'
make: *** [/root/buildroot-2011.11/output/toolchain/linux/.configured] Fehler 2

不知道我现在可以试试.我应该怎么办?

No idea what I can try now. What should I do?

推荐答案

所有构建交叉编译工具链的现代工具都依赖于实现headers_install目标的内核.因此，如Shawn所建议的，您可以尝试使用较旧的Buildroot版本，但我认为我们已经使用很长时间了，因此很久以前就必须使用headers_install，因此您必须面对很多其他问题.

All modern tools that build cross-compilation toolchains rely on the kernel implementing the headers_install target. So as suggested by Shawn, you can try with an older Buildroot version, but I think we have been using exclusively headers_install since quite a long time, so you would have to go way back in the past, and face many other problems.

该如何升级内核呢?
