glib

USE флаги

• 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
• doc - Adds extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• fam - Enable FAM (File Alteration Monitor) support
• hardened - activate default security enhancements for toolchain (gcc, glibc, binutils)
• introspection - Use dev-libs/gobject-introspection for introspection
• selinux - !!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur
• static-libs - Build static libraries
• systemtap - Build support for profiling and tracing using dev-util/systemtap
• test - Workaround to pull in packages needed to run with FEATURES=test. Portage-2.1.2 handles this internally, so don't set it in make.conf/package.use anymore
• utils - Install gtester-report utility to generate test report files for your software.
• xattr - Adds support for extended attributes (filesystem-stored metadata)
