Re: [Ltib] LTIB on Gentoo

[Ken Gilmer]

Hey Stuart,

  Yeah, my Ltibutils.pm has the Gentoo line.  I've confirmed that "/ 
usr/portage" exists on my machine:

$ ls -ld /usr/portage
drwxr-xr-x 158 root root 4096 Jan 31  2007 /usr/portage

  And that /usr/include/[gc]++ does not (assuming there is no string  
substitution in there):

$ ls -ld /usr/include/*\+\+
ls: cannot access /usr/include/*++: No such file or directory

  But if I'm reading the error and Perl right, shouldn't the problem  
be with the preceeding check, the one for 'libstdc++'?  Here is my  
libstdc check:

$ ls -ld /usr/lib/libstdc++*
drwxr-xr-x 2 root root 4096 Apr 28  2006 /usr/lib/libstdc++-v3

 I looked up the glob() function, and extracted that particular code  
into a script and ran it:

$ cat /tmp/globtest.pm
print glob('/usr/lib/libstdc++*');

$ perl /tmp/globtest.pm
/usr/lib/libstdc++-v3

So it seems the check requires more than one return here.  If I run  
the same script on my FC5 box, I get this:

# perl globtest.pm
/usr/lib/libstdc++.so.6/usr/lib/libstdc++.so.6.0.8

Since I do not know why more than one is required to be valid, I  
cannot suggest a fix for this problem.  Throwing caution to the wind,  
I changed the test such that one file expansion would pass.  It now  
seems to be running, but I'm not sure if it worked or not.  I'll  
respond back once I know.

 Here is my box version.  It is a recent install and should be  
reasonably up to date.

$ uname -a
Linux localhost 2.6.15-gentoo-r5 #1 SMP Mon Feb 13 20:23:47 UTC 2006  
i686 Celeron-A GenuineIntel GNU/Linux


Thanks
Ken
