On ppc32 (G3 and G4) with already existing and functioning gcc-4.5.3-r1, the "new" ebuild of gcc-4.5.3-r1 will not build because it fails on configure. Reproducible: Always Steps to Reproduce: 1. normal daily update of system (emerge -vauDN world) 2. today 2011-11-15 brings in gcc-4.5.3-r1 (with new cxx flags) 3. build of gcc-4.5.3-r1 with previous

Yesterday, as instructed by gmp-5.0.2 * Old versions of installed libraries were detected on your system. * In order to avoid breaking packages that depend on these old libs, * the libraries are not being removed. You need to run revdep-rebuild * in order to remove these old dependencies. If you do not have this * helper program, simply emerge the 'gentoolkit' package. * # revdep-rebuild --library '/usr/lib/libgmp.so.3' revdep req'd on '/usr/lib/libgmp.so.3' * Once you've finished running revdep-rebuild, it should be safe to * delete the old libraries. Here is a copy & paste for the lazy: * # rm '/usr/lib/libgmp.so.3' ** Running revdep-rebuild '/usr/lib/libgmp.so.3' * Configuring search environment for revdep-rebuild * Checking reverse dependencies * Packages containing binaries and libraries using '/usr/lib/libgmp.so.3' * will be emerged. * Collecting system binaries and libraries * Generated new 1_files.rr * Checking dynamic linking * There are no dynamic links to '/usr/lib/libgmp.so.3'... All done. So there seems to be a bug then in revdep-rebuild???????
Just so the order is clear. I ran revdep-rebuild yesterday, whereas I ran the update for gcc today. So, revdep should have found that gcc needed to rebuilt yesterday. eix reports: app-portage/gentoolkit-0.3.0.4-r4 I'll run revdep again now, and see if it still missing gcc.

Your machine is inconsistant and you need to run > revdep-rebuild. This seems like either (1) a bug in the message given in the e-build for libgmp, which explicitly says to use --library /usr/lib/libgmp.so.3 or (2) a bug in revdep-rebuild for not knowing that a search for /usr/lib/libgmp.so.3 should also do on on libgmp.so.3. I doubt (2), but here is why I say that: Doing what libgmp suggests, as says, does not work (even now). I get: quicky ~ # revdep-rebuild -ip -L /usr/lib/libgmp.so.3 * Configuring search environment for revdep-rebuild * Checking reverse dependencies * Packages containing binaries and libraries using /usr/lib/libgmp.so.3 * will be emerged. * Collecting system binaries and libraries * Generated new 1_files.rr * Checking dynamic linking [ 100% ] However, quicky ~ # revdep-rebuild -ip -L libgmp.so.3 && revdep-rebuild -ip both correctly identify the problem. Should this be reported as a bug to libgmp then?
Final note: I followed the same procedure which led to this problem on ppc32 on the following archs, but on those I had no problem: x86_64, x86, sparc64. Why did this problem only show up on ppc32?
OK, really is my final note on why I think there *IS* a bug to report here. Thank goodness for tmux scrollback, I re-checked the steps leading to my broken gcc (which, by the way, can't be fixed as you suggested. revdep-rebuild only suggests packages to rebuild; if gcc has been broken, you have to do some backup restores, so I think this is a rather nasty bug). Here were my steps: 1. update gmp-5.0.2 (caused by gentoo adding cxx flag) 2. immediately after update, run revdep-rebuild -ip -L '/usr/lib/libgmp.so.3' as suggested by gmp ebuild 3. immediately after that, run revdep-rebuild -ip as my script always does that after every depclean 4. immediately after that, manually delete /usr/lib/libgmp.so.3 *as the gmp ebuild says to do* 5. receive nice newly broken gcc, report bug and are told you should run revdep-rebuild, which of course, now that libgmp.so.3 is gone, reports problems. Too bad if one actually follows what the e-build says? Works on all other architectures I run. Just not ppc32. Marking the bug invalid seems like it will lead others to problems. I had backups, so no big deal. I am filing the bug for the sake of others I could image running into the same problem.
For other poor souls bitten by this, I'll add my latest encounter with this: (on amd64) 1. Do an upgrade, gmp is upgraded 2. The upgrade suggests: # revdep-rebuild --library '/usr/lib64/libgmp.so.3' 3. Using this, no files linking to it are found # rm '/usr/lib/libgmp.so.3' 4. congrats, gcc (specifically: /usr/libexec/gcc/x86_64-pc-linux-gnu/4.5.3/cc1) is now broken due to missing libgmp.so.3 4.1 Interestingly: # file /usr/libexec/gcc/x86_64-pc-linux-gnu/4.5.3/cc1 /usr/libexec/gcc/x86_64-pc-linux-gnu/4.5.3/cc1: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped # ldd /usr/libexec/gcc/x86_64-pc-linux-gnu/4.5.3/cc1 not a dynamic executable So perhaps that's why revdep-rebuild does the Wrong Thing (TM). 5. [recover libgmp.so.3 from backup] 6. # emerge -1 gcc sys-devel/gcc-4.5.3-r2 is rebuilt 7. # rm '/usr/lib/libgmp.so.3' 8. congrats, it's broken still/again 9. [recover libgmp.so.3 again] 10. Hmm. Idea: # revdep-rebuild --library 'libgmp.so.3' 11. Without the specific path, dev-libs/mpc is found to be using libgmp.so.3 and gets rebuilt 12. Now, removing libgmp.so.3 no longer poses a problem.
