You're all probably tired of CFLAGS questions by now, ignorantly I'll still ask you. Are these good Pentium 4 "Northwood" CFLAGS for gcc-3.4.1-r2?
| Code: | | CFLAGS="-march=pentium4 -mno-sse2 -O2 -pipe -fomit-frame-pointer" |
They're pretty basic, so I'm wondering if I'm missing something important. I'm worried that -mno-sse2 will be filtered in ebuilds containing "strip-flags". Would it be better to use "-march=pentium3 -mtune=pentium4"? |

Yes, it helped! Thank you. In meantime I also reported this as bug:

Sorry for not doing enough digging, but this thread is getting a bit long.
I just emerged sys-devel/gcc-3.4.1-r2 after it was unmasked. Other than sys-libs/libstdc++-v3-3.3.4, which was built along with this version of gcc, is it important that I do anything else, like emerge -e system? Is there any reason to keep sys-devel/gcc-3.3.4-r1? Thanks.

You might want to compile OOo sometime. There may be others as well that wont compile with 3.4.x.

OOo 1.1.2 might not compile with 3.4.x, but 1.9.something-or-other does robmoss will hopefully have an ebuild for us soon 
According to the gentoo-dev mailing list, 3.4.1 will be going into ~x86 proper (i.e. without the need for a special profile) soon

You mean like this...?
| morfic wrote: | gcc 3.4 is no longer profile masked in 2004.2 default profiles
it is now ~x86 in 2004.2 profiles w/o a need for a special profile
hope anyone waiting for this will be glad, not this wont get you 3.4.2
but 3.4.2-r1 is good till 3.4.2 is all finished up
the great lv will bring this to you shortly |

I've emerged gcc-3.4.1-r2 now that it is unmasked.
I've emerged -e system twice (well, second one underway).
Now I have a question about emerge -e world. I have openoffice-ximian installed, which I gather will cause emerge -e world to fall over. I dont think portage has a skip over error and continue capability (and a little forum searching just confirmed), so the whole emerge will fail with no restart possible.
So to rebuild my world am I better off temporarily removing openoffice (perhaps building a package for reinstallation) to rebuild world? Or to edit the list of packages emerge -e world throws out and then use that as the list of packages? Other approaches? |

| Removing or commenting out 'app-office/openoffice-ximian' line from /var/cache/edb/world should do as well. |

| Is there anyway to set some cflags for some specific packages in a file (like the packages.x - files)? That would be nice for instans if I want to "emerge -e world" i have to reemerge xorg afterwards with working cflags (no, commenting out it in world does not work since it is a dep for many things). |

Sorry if this question has been covered in this thread already...but I'll admit that I don't have the patience to search thru 71 pages to find the answer 
Anyway, just noticed during my latest sync that gcc3.4 is available now. It appears that it's possible to run both 3.3 and 3.4 on the same system....so my question is, how does one specify during an emerge to use either 3.3 or 3.4?
If 3.4 is installed, does the system default to using 3.4 even if 3.3 is also installed?
Is there a list of ebuilds that are known to fail with 3.4? |

You could try editing the ebuild to filter or replace cflags. I don't know if there is a better way to do it though. It would be nice if there was a package.cflags .
Now for my question: Is it necessary to do an emerge -e world after upgrading from gcc-3.4.2 to gcc-3.4.2-r1? |

| Xview fails with gcc-3.4 and does not abort. So you get a broken install .. |

ch42:
When you emerge 3.4 it will be set to your default. If you then want to compile something using 3.3 then you could switch using:
| Code: | gcc-config i686-pc-linux-gnu-3.3.4
source /etc/profile |
After that the system uses 3.3 as default until you switch back using the same command but change the "3.3.4" part.
If you wan to know what is currently the one in use:
And the ebuild I know will fail is all somehow connected to OOo.
xorg will compile but not work if you compile it using -march=penium4 qithout specify -mno-sse2.
hitman_bond007:
Maybe file a bug? packages.cflag I think would be nice.
I dont know, but is there a meaning at all right now to do a emerge -e world every 3.4.x bump if you don't find any troubles mixing? And since an -r1 not change TAHT much...... Or am I wrong? |

"Necessary" was probably the wrong word to use. Mostly what I want to know is if the changes made in -r1, -r2, etc. are normally going to be significant enough to cause problems.
I would assume that 3.4.x bumps generally won't cause problems, I just like to have as much as possible compiled with the same gcc release. |

Does that work?
Isn't it:
emerge -e world, and then when it fails
emerge --resume --skipfirst ?

nope, because when it fails and you do | Code: | | emerge --resume --skipfirst |
emerge will not know what to emerge, where to emerge from etc.
so the correct sequence would be
and when it fails if it fails etc
| Code: | | emerge -e world --resume --skipfirst |

Well emerge --resume --skipfirst works here
If your way works too (haven't checked yet) then that's some nice extra functionality, but it's not necessary unless another emerge finishes/fails in between the emerge -e world failing and you typing the command

hehe, I remember my first post in this forum being about exactly such a feature.
I was told I shouldnt use crazy CFLAGS and that such a feature would not exist in the near future^^ |

No. emerge --resume always resumes the last merge, whatever it was. Metal leper was right. |
