Package: libc6-dev
Version: 2.3.2.ds1-11
Severity: grave
Tags: experimental
Justification: renders package unusable
Hello, Im Debian-sarge user.
function 'pow' are suppose to be in the 'math.h' according the "C
Library manual" glibc-doc.. :
file:///usr/share/doc/glibc-doc/html/libc_19.html#SEC394
(if you have it installed)
That was that.
But there is one more thing that puzzle me is this:
Command: "dpkg -l glibc*" list:
un glibc (Don't exist in my dselectlist)
un glibc-2.3.2.ds1-11 (Don't exist in my dselect-list nether)
ii glibc-doc 2.3.2.ds1-11 (THIS EXIST, I have it installed) GNU C Library: Documentation
un glibc-pic (Don't exist in my dselectlist)
un glibc2 (Don't exist in my dselectlist)
un glibcdoc (Don't exist in my dselectlist)
And command: "dpkg -l libc6*" list:
ii libc6 2.3.2.ds1-11 GNU C Library: Shared libraries and Timezone data
un libc6-bin (Don't exist in my dselectlist)
pn libc6-dbg
ii libc6-dev (this bugreport! GNU C Library: Development Libraries and Header Files)
un libc6-doc (Don't exist in my dselectlist)
pn libc6-i686
pn libc6-pic
pn libc6-prof
un libc6.1 (Don't exist in my dselectlist)
un libc6.1-dbg (Don't exist in my dselectlist)
un libc6.1-dev (Don't exist in my dselectlist)
un libc6.1-pic (Don't exist in my dselectlist)
I have both a updated apt-list and dselectlist!
I speculate that "glibc-doc" don't document "libc6"..
( I use ftp.dk.debian.org, in my /etc/apt/sources.list file)
Any ideer whats wrong???
