[PATCH v2] kmod-native_git.bb: fix builds for hosts with older libc

[PATCH v2] kmod-native_git.bb: fix builds for hosts with older libc

[Matthew McClintock]

kmod will fail to build with the following error because O_CLOEXEC is
not defined:

| libkmod/libkmod-module.c: In function 'kmod_module_get_initstate':
| libkmod/libkmod-module.c:1640: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c:1640: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-module.c:1640: error: for each function it appears in.)
| libkmod/libkmod-module.c: In function 'kmod_module_get_refcnt':
| libkmod/libkmod-module.c:1754: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c: In function 'kmod_module_get_sections':
| libkmod/libkmod-module.c:1913: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c: In function 'kmod_file_open':
| libkmod/libkmod-file.c:282: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c:282: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-file.c:282: error: for each function it appears in.)

Since we are only using kmod-native for depmod, and it's a non-threaded
user of this libary being built this should be safe to override O_CLOEXEC.

Keep in mind this is ONLY effecting the native builds and not what is
being shipped in the root file system.

IMO It would be safer to create a patch for kmod itself where you
define O_CLOEXEC if it
was not defined before. The above seems a bit risky

Why is it risky? I only wanted to do this for affected systems. There
is not an easy way to do this with a patch, unless of course I apply
the patch manually.

manually gripping at the host installation and then if O_CLOEXEC might
be in comments
and furthermore it if it comes from fcntl.h which is not where you are
looking for
there are few variables like that where its impacting more than
affected systems.

How about grep define.*O_CLOEXEC -r ${includedir_native}/bits/fcntl.h

I am grepping this file though?

I would go into the specific file where its asking for O_CLOEXEC

and add

#ifndef O_CLOEXEC
# define O_CLOEXEC 0
#endif

and be done with it

Wasn't this proposed back a month ago:

http://lists.linuxtogo.org/pipermail/openembedded-core/2012-July/026343.html

And there was discussion about that approach then? I think it was 
rejected due to lack of testing.

Then we had a bit more analysis and discussion on the issue and others
chimed in they had implemented similar work arounds... it's all in
that thread.

Well this is seemingly the same way of doing it, just looks like you
always want it applied? I don't think it should always be applied.

If this was it takes to get the build fix in, then I will do it...
please confirm what will be accepted.

I think if it worked fine on a system like cents 5.8 then that would
cover the case
as well try it on newer systems where O_CLOEXEC is available that should do it.

This does seem like a nicer approach.

OK - 2v1 ;) I'll respin as a patch.

No, on newer systems O_CLOEXEC will be defined, so that #ifndef block
will never be entered, and there'll be no change.

Right, I was not thinking...

[PATCH v2] kmod-native_git.bb: fix builds for hosts with older libc

[Matthew McClintock]

kmod will fail to build with the following error because O_CLOEXEC is
not defined:

| libkmod/libkmod-module.c: In function 'kmod_module_get_initstate':
| libkmod/libkmod-module.c:1640: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c:1640: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-module.c:1640: error: for each function it appears in.)
| libkmod/libkmod-module.c: In function 'kmod_module_get_refcnt':
| libkmod/libkmod-module.c:1754: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-module.c: In function 'kmod_module_get_sections':
| libkmod/libkmod-module.c:1913: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c: In function 'kmod_file_open':
| libkmod/libkmod-file.c:282: error: 'O_CLOEXEC' undeclared (first use in this function)
| libkmod/libkmod-file.c:282: error: (Each undeclared identifier is reported only once
| libkmod/libkmod-file.c:282: error: for each function it appears in.)

Since we are only using kmod-native for depmod, and it's a non-threaded
user of this libary being built this should be safe to override O_CLOEXEC.

Keep in mind this is ONLY effecting the native builds and not what is
being shipped in the root file system.
