| Code: | equery d gmp
* These packages depend on gmp:
dev-libs/mpfr-3.0.0 (>=dev-libs/gmp-4.1.4-r2)
dev-libs/openssl-1.0.0a (gmp ? dev-libs/gmp)
sys-apps/coreutils-8.5 (gmp ? dev-libs/gmp)
sys-devel/gcc-4.3.2-r4 (>=dev-libs/gmp-4.2.1)
|
but mpfr is also a gcc dependency
| Code: | equery d mpfr
* These packages depend on mpfr:
sys-devel/gcc-4.3.2-r4 (>=dev-libs/mpfr-2.3)
|
so check gmp & mpfr (as you already check gmp)
for gdbm it's python that depend on it (and perl), but as python=emerge, might be good to check it too.
well, without an error log, can't guess more. |

[32;01m*[0m CXXFLAGS=""

i think it's that, your CFLAGS are cleared.
check your gcc env & gcc-config -l (and ask gcc-config to switch to the same gcc version)
edit: yeah the config.log

config.log: http://pastebin.org/439779
I see this:

you've break your gcc :p
/usr/libexec/gcc/x86_64-pc-linux-gnu/4.4.3/cc1: error while loading shared libraries: libmpfr.so.4: cannot open shared object file: No such file or directory
bad idea to remove libmpfr.so.4
try locate another copy and link to that one, else use the tinderbox to grab it
revdep-rebuild could repair that, but it will ask emerge to rebuild mpfr, and of course emerge will ask gcc to rebuild it -> chicken & egg
edit: i think there's a thread for that, or at least, i saw neddyseaggon explain a guy how to fix it with the tinderbox
or check the https://forums.gentoo.org/viewtopic-t-832937.html

Uhh yeah I kinda figured that.

What? You'd think I'd run "rm -fr --no-preserve-root /" as well? Come on.

I understand but don't know how to do that.
Nevermind I found the location in the man page

At least there's a legit reason to do that. |

on a more serious note, the link i gave upper to the sticky "i remove mpfr by mistake" explain anything to correct your issue |

I downloaded the newer version of mpfr from that site and put it in /usr/portage/packages/ and ran "emerge -k mpfr" but portage still tries to compile mpfr and fails.

need v3.0.0 package, it might work but you should emerge -k =mpfr-version to force the package version (else emerge might just try to emerge the version you have and not the package version) |

Still tries to compile the source instead of using the tarball. |

Okay so it installed mpfr via the tarball but gcc still can't compile. I'll get the config.log file in a moment.
http://pastebin.org/439845
I fixed it! Two files were missing in /usr/lib: libmpfr.so.4 and libgmp.so.3, so I symlinked libmpfr.so to libmpfr.so.4 and libgmp.so to libgmp.so.3
| Code: | cd /usr/lib
ln -s libmpfr.so libmpfr.so.4
ln -s libgmp.so libgmp.so.3 |
But my question is, why did I have to do that? Why are there four symlinks in the same directory pointing to the same file in the same directory as the sysmlinks?

well, same error as before try slocate mpfr.so
or download the 3.0.0 version (at least i'm sure the file is in that one)
edit: ah ok great, try rebuild them to have the good libs.
then revdep-rebuild to check
| Code: | ls /usr/lib/libmpfr.so.* -l
-rwxr-xr-x 1 root root 305396 2 août 02:12 /usr/lib/libmpfr.so.1
lrwxrwxrwx 1 root root 16 2 août 02:12 /usr/lib/libmpfr.so.4 -> libmpfr.so.4.0.0

I hope my solution works for the original poster.
On an unrelated note, why does gcc have a gtk USE flag? |

no idea about the gtk use flag for gcc
the original poster will be fine when he will fix is ldflags, the dup -wl,--as-needed without a space = bork ldflags -> C compiler cannot...
(ok he might not, but that would be another issue) |

Hello, it seems it was glibc that had issue with my ldflags, i commented them out and it built fine and so did everything else. Now since then i get eselect new item telling that -Wl,--as-needed has been added to default profile, i can also add this to ldflags which will override default profile.
What the issue it is now working.

I found that apparently it had updated the C++ libraries and my paths (specifically in /etc/ld.so.conf), were now wrong. In order to fix it I had to:
1) edit /etc/ld.so.conf to fix the gcc-lib path (in my case it went from 3.2.3 to 3.3.3.
2) run "ldconfig" to set the proper library path
3) edit /etc/env.d/05gcc and change all the paths to the new version.
If you don't do steps 1 and 2 you won't be able to run emerge again. If you don't do step 3, it will undo your changes from step 1 when you run emerge again.
Hope this helps...

Hey Robert
this helped massively. Thought i would pull this thread up to date this is a important addition as i broke my system doing a emerge --depclean
I had 3 compilers on my system version 3.x a 4.3x and current 4.4.x
So i am sure you can imagine -depclean removed 3.x and 4.3.x but left the directory listings in the 05gcc files.
BTW 05gcc file has on my system located as: "/etc/env.d/05gcc-i686-pc-linux-gnu" so anyone need assistance in finding the file cd into /etc/env.d and find which file ending there is by doing a "ls" in that directory. I would also advise on opening a second terminal(I was in X windows so multiple terminals were open) cd each gcc directory listed in the 05gcc file to double check they exist and contain files this is a good way of checking that gcc is installed and the version it points to exists.
Most important find i have found to fix this problem something not mentioned in Roberts post was after modifying all the directories in the files make sure you run:
If you dont it wont take effect unless you reboot which i dont advise on a broken system rofl. so to conclude the perfect fix Thank You Robert:

Thanks again all and hope this helps someone.

I was emerging and compiling stuff just fine.
Finally, wine failed to emerge with a bus error. After that, I can emerge NOTHING! Every attempt says my C compiler cannot create executables, and the associated config.log looks like this (for a ccache emerge, for example):
!!! Please attach the following file when seeking support:
configure:2063: Configuring ccache

INPUT_DEVICES="evdev"

--------------------------------------------------------
On the other hand, I can compile my own programs just fine.
$ gcc myprog.c
works perfectly, giving me a working a.out
Any thoughts on where to look? |

Personnellement, toutes ces méthodes n'ont pas marché. seul
cd /etc
rm make.profile
ln -s ../usr/portage/profiles/default/linux/x86/2008.0/server make.profile
env-update && source /etc/profile
a fonctionné. (RPS OVH Release 2) |
