Red Hat Bugzilla – Bug 14666
missing symlinks in kernel-headers causes compiles to fail
Last modified: 2008-05-01 11:37:57 EDT
In the process of upgrading the "kernel-headers" RPM from v2.2.14-5.0 to v2.2.16-3, two symlinks which were present in the previous version are now absent in the current version. Without these symlinks, certain compiles fail. Specifically, any C code which includes the header file "/usr/include/sys/param.h" will fail to compile. The missing symlinks in-question are the following: /usr/include/asm -> ../src/linux/include/asm /usr/include/linux -> ../src/linux/include/linux Here is a contrived code example (which will fail to build): #include <stdio.h> #include <sys/param.h> int main() { printf("Hello world\n"); } PS: What's the point of the "Component Text" field in the bugzilla page if I can't submit a component that isn't in the list? I tried submitting "kernel-headers", but I got rejected and had to type the whole Description over again. Pain in my ass...
I can not reproduce this bug. Installing "kernel-headers-2.2.16-i386.rpm" on my machine results in correct symlinks. Furthermore, a quick check of the rpm SPEC file shows the following commands being executed: cd /usr/include rm -f linux asm ln -snf ../src/linux/include/linux linux ln -snf ../src/linux/include/asm asm Were you running as root when you installed the rpm?
I was running as "root" when I installed the RPM. However, unless you made a typo in your reply to me, it looks like you installed a different RPM than I did. I installed the RPM "kernel-headers-2.2.16-3.i386.rpm", whereas you're telling me that you installed an RPM by the name "kernel-headers-2.2.16-i386.rpm" (it's missing the "-3" suffix to the "2.2.16" version number). And when I do an "rpm -qlp" on the file, the two symlinks in-question are missing from the list. As far as I'm aware, this is the latest binary kernel RPM file. I got it off of the tux.org mirror, but I think it was also the latest according to a search I did on the RedHat updates page. I'll check again to see if another update was slipped by since I last checked. Are you sure you're using the latest RPM?
You are right about the typo. However, I still get correct behavior from this RPM. Please execute the command: rpm -U -vv --force kernel-headers-2.2.16-3.i386.rpm and attach the last 50 or so lines of output to this bug report, along with the output of a 'uname -a' command.
Created attachment 1613 [details] gzipped tar of text files containing command output from rpm command-lines
Okay, I attached a gzipped-tar of command output that would help debug the problem. However, there were two snags. Firstly, in order for it to be useful, I gave more than just the last 50 lines of the rpm command output. Also, the command you told me to use failed due to dependency problems, so I had to install both "kernel-headers" and "kernel-source" on the same command-line.
The output that you included shows that the symlinks were created on your machine. From the file typescript.3.txt: ... D: running preinstall script (if any) kernel-headers-2.2.16-3 GZDIO: 467 reads, 3817852 total bytes in 0.009 secs D: running postinstall scripts (if any) + cd /usr/src + rm -f linux + ln -snf linux-2.2.16 linux + cd /usr/include + rm -f linux asm + ln -snf ../src/linux/include/linux linux + ln -snf ../src/linux/include/asm asm ...
Okay, I didn't notice that earlier. But that's on lines 1498 and 1499. Later on in "transcript.3.txt", on lines 2870 and 2871, the symlinks get removed again. It looks like there's an "order-of-operations" problem going on here. Perhaps the symlinks want to be created in the "postuninstall" stage. ...

It looks like you forgot to enter a comment explaining why the bug is resolved. Is a new RPM being released with the bug fix? _____ Please go to this URL: http://www.redhat.com/swr/i386/kernel-headers-2.2.16-3.i386_fl.html This file list does not show the symlinks: /usr/include/asm /usr/include/linux
