Version 1.0.19 restructured the breakout -libraries, libcrypt.so.0, libdl.so.0, and friends. The functions in -those libraries are now included in libuClibc-0.1.0.19.so. Version -1.0.21 and above removed libc support for obstack, expecting packages to -use their bundled GNU lib code. Both changes require special upgrade -procedures which we outline below: - -0. Because of changes in the library structure in previous versions, -make sure you are working with 1.0.19 and rebuild world using - - emerge -e @world - -This will make sure all the executables link directly against libc.so.0 -(as reported by `readelf -d`) rather than via symlinks like libdl.so.0 --> libc.so.0. Then upgrade from 1.0.19 to 1.0.20 without symlink-compat: - - USE="-symlink-compat" emerge =sys-libs/uclibc-ng-1.0.20 - -1. Get rid of the obstack.h header since it's used by configure scripts -to look for function prototypes and macros. - - mv /usr/include/obstack.h ~ - -2. We also need to force the use of any bundled gnu lib code. We can do -this by removing the definition of _GNU_OBSTACK_INTERFACE_VERSION from -gnu-version.h - - cp /usr/include/gnu-versions.h ~ - sed -i -e '/#define _GNU_OBSTACK/d' /usr/include/gnu-versions.h - -3. We need to tell stdio.h that __UCLIBC_HAS_OBSTACK__ is false.

To be safe, you may want to back up your entire /lib directory so -you can fall back should something go wrong: - - cp -a /lib /lib.bak - -5.
