[/usr/src/kernels/2.6.9-34.0.2.EL-i686]# make bzImage
CHK include/linux/version.h
CHK include/asm-i386/asm_offsets.h
UPD include/asm-i386/asm_offsets.h
/bin/sh: arch/i386/kernel/asm-offsets.s: No such file or directory
mv: cannot stat `include/asm-i386/asm_offsets.h.tmp': No such file or directory
make: *** [include/asm-i386/asm_offsets.h] Error 1

This is because RHEL4 doesn’t install kernel source package by default, but install a package including minimum kernel header and source file (kernel-devel-$(uname -r).i686.rpm).

This package provides kernel headers and makefiles sufficient to build modules against the kernel package. Hence it cannot be used to build kernel source.

To re-build kernel, please to see the “kernel” section in the release-notes in RHEL 4.

In order to eliminate the redundancy inherent in providing a separate package for the kernel source code when that source code already exists in the kernel’s .src.rpm file, Red Hat Enterprise Linux 4 no longer includes the kernel-source package. Users that require access to the kernel sources can find them in the kernel.src.rpm file.

To create an exploded source tree from this file, perform the following steps:

  1. Obtain the kernel-$(uname -r).src.rpm file from one of the following sources:
    • The SRPMS directory on the appropriate “SRPMS” CD iso image
    • By running the following command:
      up2date –get-source kernel
  2. Install kernel-$(uname -r).src.rpm
    rpm -Uvh /var/spool/up2date/kernel-$(uname -r).src.rpm (if kernel.src.rpm is gained by up2date)
  3. Change directory to /usr/src/redhat/SPECS/
  4. rpmbuild -bp –target=$(uname -m) kernel-2.6.spec
  5. Issue the following command:
    make oldconfig

You can then proceed as usual.

我接下來會有這個系列幾篇的文章, 講一下怎樣安裝好 RPM. 我會拿 perl-Text-Iconv 這個還蠻多程式會用到的 perl module 來當例子.

第一個是手動的方法.

1. 判斷你要安裝的系統是哪個 linux distribution

我相信應該自己會知道是 RedHat, Gentoo, Debian, 或是 Ubuntu. 這裡只會講 RedHat Enterprise Linux (RHEL), 以及 RedHat Fedora (FC). 判斷的方法就是

# cat /etc/redhat-release

比方說, 結果是 Red Hat Enterprise Linux ES release 4 (Nahant Update 3), 就是 RHEL4 ES Update3; Red Hat Enterprise Linux AS release 3 (Taroon), 就是 RHEL4 AS. Fedora 的例子比方說 Fedora Core release 3 (Heidelberg) 就是 Fedora Core 3. 如果是 Red Hat Enterprise Linux 的話, 因為 RedHat 已經不提供 public binary RPM 的服務, 所以本篇對您可能沒有幫助, 請見本系列的下一篇.

2. 到 Official site 找 RPM

根據 Fedora Core Wiki Site, Fedora 的 Official Download Location 如下:

找到你需要的 RPM 再安裝即可. 就我們 perl-Text-Iconv 這個例子來說, 就是在 Fedora Extras 裡就可以找到 RPM 了.

3. 到 Un-official site 找 RPM

如果您要找的 RPM 還找不到, 那一般來說, 大家都會到 rpmfind.net 來找非官方的 RPM. 這也是個信賴度比較高的網站. 比方說, 這個 URL http://rpmfind.net/linux/rpm2html/search.php?system=fedora 就是只 query Fedora 的 RPM.

如果以上還找不到, 基本上是可以求助 google 大神. 不過這個就要小心那些 RPM 是不是有被放入木馬的可能性了.
