Bug 111064 – linux-info should not check for module-support when it is not building a module

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description Christian Hesse 2005-10-31 15:34:03 UTC]

Linux kernel 2.6.14 includes support for FUSE. I've built it into the kernel 
and module support is disabled. With this configuration I can't emerge sys-fs/
fuse. Removing "inherit linux-mod" from ebuild solves the problem.


Reproducible: Always
Steps to Reproduce:
1. use 2.6.14, enable FUSE, disable module support
2. emerge sys-fs/fuse

Actual Results:  
emerge stops with an error, it misses module support in the kernel.


Expected Results:  
emerge fuse

From `emerge sys-fs/fuse` (~x86 version, but the same check is present in 
latest stable as well, iirc): 
  
 * Determining the location of the kernel source code  
 * Found kernel source directory:  
 *     /usr/src/linux  
 * Found sources for kernel version:  
 *     2.6.14-gentoo  
 * Checking for suitable kernel configuration options:  
 *   We have detected FUSE already built into the kernel.  
We will continue, but we wont build the module this time.  
 * Please check to make sure these options are set correctly.  
 * Failure to do so may cause unexpected problems.  
>>> Unpacking source...  
  
  
Works fine with siefs. I'd suggest RESOLVED WORKSFORME.

well, jkt you are right but the issue here is different.

Linux-info behaves wrong here.

[Comment 3 Christian Hesse 2005-11-01 15:57:45 UTC]

To make shure everybody understands what I'm steaking about:

 * Checking for suitable kernel configuration options:
 *   We have detected FUSE already built into the kernel.
We will continue, but we wont build the module this time.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.

This part is ok.

 * These sources do not support loading external modules.
 * to be able to use this module please enable "Loadable modules support"
 * in your kernel, recompile and then try merging this module again.

That is what causes the problem. emerge aborts after this message.

johnm: any progress with this?

[Comment 5 John Mylchreest (RETIRED) 2005-12-30 10:33:35 UTC]

if im going to be strict over this, I would suggest splitting the fuse ebuild into fuse-utils and fuse-kernel or some such, since technically speaking linux-mod is doing the correct thing by exiting when it cannot confirm module support.

However, that being said, if you think this is a valid problem for now I would suggest re-defining pkg_setup as follows:

pkg_setup() {
        linux-info_pkg_setup;
        check_kernel_built;
        set_kvobj;
}

If you prefer, throw the question/bug to gentoo-kernel@ and we can bash it out to come up with a finer solution.
