Bug#387446: glibc: Please compile for (/usr)/lib64 on amd64 as per FHS
Package: glibc
Version: 2.3.6.ds1-4
Severity: serious
Tags: patch
Hi,
the standard location for libraries on amd64 is (/usr)/lib64 but glibc
is build for (/usr)/lib. In most cases this makes no difference but
there are some:
1) Compatibility with other linux
When you copy debians libc6 or static binaries to other linux systems
then the location of plugins changes from /usr/lib to /usr/lib64
(/usr/lib/gconv/ becomes /usr/lib64/gconv/).
2) automatic conversion for multiarch
The same thing happens here. The converter for multiarch deletes the
(/usr)/lib64 link and changes (/usr)/lib to (/usr)/lib64 so the
library does not conflict with its 32bit counterpart. Again
/usr/lib/gconv/ becomes /usr/lib64/gconv/ and so on.
The attached patch is a simple solution to the problem. Glibc on amd64
gets compiled for (/usr)/lib64 as the FHS/LSB specify for amd64 but
before packaging it gets renamed to (/usr)/lib and (later) the
lib64->lib links are put in place.
This way it works everywhere.
------------------------------------------------------------------------------
I set this to serious because it sort of violates a MUST directive in the FHS:
http://www.debian.org/doc/packaging-manuals/fhs/fhs-2.3.html
| /lib64 and /lib32 : 64/32-bit libraries (architecture dependent)
|
| The 64-bit architectures PPC64, s390x, sparc64 and AMD64 must place
| 64-bit libraries in /lib64, and 32-bit (or 31-bit on s390) libraries
| in /lib.
It does not specificaly mention plugins but I hope you agree the same
rational applies there for libc6.
