I have a system that was built with USE="nptl nptlonly" and profile 2006.1/desktop
I now want to use the newer profile 2007.0/desktop. When I emerge glibc, it won't use the nptl adn nptlonly flags:
Code: Select all
Zeus ~ # USE="nptl nptlonly" emerge -pv glibc
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild U ] sys-libs/glibc-2.6.1 [2.5-r4] USE="nls -debug -glibc-compat20 -glibc-omitfp (-hardened) (-multilib) -profile (-selinux) (-build%) (-nptl%*) (-nptlonly%*)" 16,006 kB
Total: 1 package (1 upgrade), Size of downloads: 16,006 kB
Strangely equery still reports that the nptl flag will be used:

[ Colour Code : set unset ]
[ Legend : Left column (U) - USE flags from make.conf ]
[ : Right column (I) - USE flags packages was installed with ]
[ Found these USE variables for sys-libs/glibc-2.5-r4 ]
U I
- - build : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1]
- - debug : Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see http://www.gentoo.org/proj/en/qa/backtraces.xml .
- - glibc-compat20 : Enable the glibc-compat addon.
- - glibc-omitfp : Configure glibc with --enable-omitfp which lets the build system determine when it is safe to use -fomit-frame-pointer
- - hardened : activate default security enhancements for toolchain (gcc, glibc, binutils)
- - multilib : On 64bit systems, if you want to be able to compile 32bit and 64bit binaries
+ + nls : Adds Native Language Support (using gettext - GNU locale utilities)
+ + nptl : Enable support for Native POSIX Threads Library, the new threading module (requires linux-2.6 or better usually)
+ + nptlonly : Disables building the linuxthreads fallback in glibc ebuilds that support building both linuxthreads and nptl.
- - profile : Adds profile support to builds of packages (will likely vary from ebuild to ebuild in support)
- - selinux : !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
BTW. The system does not use unicode:
Code: Select all
Zeus ~ # equery uses baselayout
[ Searching for packages matching baselayout... ]
[ Colour Code : set unset ]
[ Legend : Left column (U) - USE flags from make.conf ]
[ : Right column (I) - USE flags packages was installed with ]
[ Found these USE variables for sys-apps/baselayout-1.12.9-r2 ]
U I
- - bootstrap : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used during original system bootstrapping [make stage2]
- - build : !!internal use only!! DO NOT SET THIS FLAG YOURSELF!, used for creating build images and the first half of bootstrapping [make stage1]
- - static : !!do not set this during bootstrap!! Causes binaries to be statically linked instead of dynamically
- - unicode : Adds support for Unicode
