Re: /usr/include/bits/local_lim.h:36: linux/limits.h: Permission denied (SOLVED, please read!)

[Manuel Bilderbeek <manuel@msxnet.org>]

Hello again,

I forgot to mention that this Permission denied doesn't occur when I run 
./configure (or another program that does an (implicit) #include 
<limits.h>) as root.

Even when I try to compile this program:
#include <limits.h>

int main(void)
{
}

I get this:
/tmp> gcc testing.c -o testing
In file included from /usr/include/bits/posix1_lim.h:126,
                 from /usr/include/limits.h:144,
                 from 
/usr/lib/gcc-lib/i386-linux/2.95.4/include/limits.h:117,
                 from 
/usr/lib/gcc-lib/i386-linux/2.95.4/include/syslimits.h:7,
                 from 
/usr/lib/gcc-lib/i386-linux/2.95.4/include/limits.h:11,
                 from testing.c:1:
/usr/include/bits/local_lim.h:36: linux/limits.h: Permission denied
Exit 1

I'm 100% sure it worked before, and it also works on all other Linux 
systems I have seen! (Logically...)

I simply can't understand the Permission denied...
What linux/limits.h is it including?

Hmm, now I tried this:
/tmp> gcc-3.0  testing.c -o testing
In file included from /usr/include/bits/posix1_lim.h:126,
                 from /usr/include/limits.h:144,
                 from 
/usr/lib/gcc-lib/i386-linux/3.0.4/include/limits.h:125,
                 from 
/usr/lib/gcc-lib/i386-linux/3.0.4/include/syslimits.h:7,
                 from 
/usr/lib/gcc-lib/i386-linux/3.0.4/include/limits.h:11,
                 from testing.c:1:
/usr/include/bits/local_lim.h:36:26: /usr/local/include/linux/limits.h: 
Permission denied
Exit 1

Hey, GCC 3.0 gives me a better idea where to look!

/usr/local/include/linux:
this directory was created by the lm-sensors package (as far as I know) 
and did not have the right permissions!

Changing the permissions of this directory solved the problem...
Although this /usr/local/include directory does not contain limits.h, it 
*does* seem to be search by the include system. And if it cannot search 
into it, errors occur.

Is this a package bug? Or is it my own fault? (Maybe I shouldn't have 
installed the lm-sensors stuff as root? (How else then? ;-))

Best regards,

Manuel Bilderbeek
