I ran that find command again, it found some stuff this time. Remerged without the -fstack-protector, updated gcc, remerged with -fstack-protector, remerged offending programs.
works great! |

On my system, the __guard check didn't do anything (I waited for about 1 hour). A "ps auwx" covered the problem: readelf was not responding while checking the file "/usr/X11R6/bin/a.out".
| Code: | | root 24990 62.5 0.1 1720 692 pts/1 S 11:30 1:31 readelf -s /usr/X11R6/bin/a.out |
After doing: | Code: | | $ pidof readelf | xargs kill |
the __guard check resumed.

Ok, i have recompiled gcc with fstack-protector and tried to recompile necessary apps, trouble so are still coming up on find command.
qt
kde
aspell
KDE has long list of stuff, kde-base, kde-games etc. when viewing kde emerge it downloads but does not recompile:
root@hamlet michael # emerge kde
Calculating dependencies ...done!

How can i force this packages to recompile with new USE flags and so allow gcc update?
cheers

I don't receive any output from the find... command. It runs for a few minutes and then returns to the prompt.
edit: I checked the ebuild file. First it checks if glibc is "infected" - which it is in my case. If it is, it also does this check:
| Code: | SCANPATH="$(for i in $(cat /etc/ld.so.conf | grep -v '/usr/lib/gcc-lib' | grep -v '^\#'); do echo -n $i; echo -n ' '; done) $(echo ${PATH} | sed 's,:, ,g')"
if [ "$(find ${SCANPATH} -type f -perm -1 -maxdepth 9 -exec readelf -s {} \; 2>&1 | grep "__guard\@GCC" 2>&1 1>/dev/null; echo $?)" == "0" ]
then
eerror "found binaries that are dynamically linked to the libgcc with __guard@@GCC"
[...] |
It scans the files in scanpath for __guard flags and if there are none found (== "0") it gives the message that it found some ? This isn't right, is it ?
(Just a guess -- I'm quite new to linux and don't even know what kind of language this is but judging from my c knowledge I'd say this is not working as intended. Or is it ?) |

|

I'm currently on gcc 3.2.3-r2 trying to emerge to gcc 3.2.3-r3. I received the message that glibc contains the guard and stack_smash functions. I've removed the stack_smash from make.conf and even put in -fno-stack-protector to explicitly inidicate no stack protector. I've also wiped the ccache directory. Then I recomiled glibc 2.3.2-r3 successfully. When I attempted to emerge to gcc 3.2.3-r3 I got the same message.
I'm hoping it's something obvious that you more experienced people can point out to me. Am I at least headed in the right direction? I even tried re-emerging my current version of gcc without stack-protector as was suggested in a previous post, but that emerge failed.
emerge error message and emerge info below:
| Code: | * Applying protector.dif... [ ok ]
* Applying gcc-323-propolice-version.patch... [ ok ]
* this sys-libs/glibc has __guard object and __stack_smash_handler functions
* scanning the system for binaries with __guard - this may take 5-10 minutes
* please do not press crtl-C or crtl-Z during this period - it will continue
* found binaries that are dynamically linked to the libgcc with __guard@@GCC
* you need to compile these binaries without CFLAGS -fstack-protector/hcc -r
* also you have to make sure that using ccache needs the cache to be flushed
* wipe out /var/tmp/ccache or /root/.ccache, this will remove possible saved
* -fstack-protector arguments that still may reside in such a compiler cache
* when such binaries are found, gcc cannot remove libgcc propolice functions
* leading to gcc -static -fstack-protector breaking, see gentoo bug id 25299
* you can run 'qpkg -f' from the gentoolkit package and reemerge the program
* to do a full scan on your system, enter this following command in a shell: |

Was your current version of gcc (3.2.3-r2) emerged with -fstack-protector? If so, I think you have to re-emerge your current version of gcc without -fstack-protector before you can emerge the new gcc. This worked for me, after puzzling for a little while about what the block was. I think you may have to re-emerge glibc again with the fresh version of the old (-r2) gcc, too; it's been a couple of weeks since I did it, and don't remember for sure whether I did that, but in any case, it won't hurt.
So, to be clear, what I'm suggesting is: re-emerge gcc-3.2.3-r2 and then glibc (in both cases, your existing versions) without -fstack-protector, then try emerging the new gcc (3.2.3-r3). After all that's done, you can put -fstack-protector back in your $CFLAGS, and re-emerge anything you want to be protected by it.
If that doesn't work, did running the lengthy find command suggested by the gcc-3.2.3-r3 ebuild produce any output? That might offer some clues. |

As recommended in previous a post I have tried to emerge gcc-3.2.3-r2 without stack-protector flag with the intent of recompiling glibc afterward. The gcc emerge doesn't complete. I've included the last portion of the log which includes the error. I don't possess the technical sophistication to understand what is causing the error so I'm not able to more forward. My emerge info was posted a couple posts back.
Is there a way to replace my gcc-3.2.3-r2 which was compiled with the stack-protector flag with a precompiled binary version? Or if I'm going to go to gcc-3.2.3-r3 anyway should I look for that in a binary package?

Right, sorry about that; I missed that you mentioned you had tried re-compiling before.
One hunch: if 'emerge -pv gcc' shows that 'nls' is enabled among your USE flags, try emerging with -nls, i.e.,
| Code: | | USE="-nls" emerge /usr/portage/sys-devel/gcc/gcc-3.2.3-r2.ebuild |
I remember running into mysterious compilation errors before, which I fixed by putting '-nls' in $USE (nls is enabled in the global make.defaults). I'm not a gcc expert, but the errors you got seem somehow text-related, hence this nls hunch.
Otherwise, I don't know anything about any available binary gcc packages. Maybe try emerging gcc-3.2.2?
Best of luck. |

gcc-3.3.2-r4 has been released, which apparently loosens the -fstack-protector detect thingy a bit, so its probably worth trying that one as well
